Good to see us here, back at a talk session, 0:13 here in the office again. It's my pleasure today to introduce Dr. Michio Kaku 0:20 and to hear his guest lecture here about his new book, which is-- 0:26 if you've read a lot of his books, you know he's been working up to, hopefully, quantum computing. And his new book, "Quantum Supremacy-- 0:34 How quantum computers will change everything." Dr. Kaku clearly has figured out how 0:40 to work in multiple universes because, in addition to being a bestselling author, he's 0:46 also a professor, a father, and an academic author 0:51 in the space of physics. So with that, I would like to welcome onto the stage, for our guest lecturer today, Dr. Michio Kaku. 1:00 [APPLAUSE] 1:09 MICHIO KAKU: Well, after such a great introduction, I can't wait to hear the speaker myself. 1:15 [LAUGHTER] First of all, let me say that I have the privilege of dealing 1:20 with other great scientists. And every time I meet a scientist, I ask them the key question, the most important question of all. 1:31 I ask them, is there intelligent life on the Earth? 1:36 [LAUGHTER] Well, I was watching "The Kardashians" on TV last night. [LAUGHTER] And I'm convinced there is no intelligent life 1:44 on this planet. Nope, not on this planet, except in this room. 1:49 [APPLAUSE] I think that, in this room, we have some of the most inquisitive, energetic, creative minds 1:56 on the planet. And also, I signed copies of my latest book for you. 2:02 After you pick up a copy of my signed book, you can go to eBay and auction them off for money. 2:08 [LAUGHTER] That's right, you can actually make money on today's lecture. Let me also say that in two weeks, 2:15 I'm flying to Santa Barbara. I'll be touring the quantum computer facility for Google 2:22 at Santa Barbara for 60 minutes, and it'll be filmed. And then it'll show up perhaps in fall. 2:29 So watch for it. We're going to talk about quantum computers. These are, by the way, some of the books that I've written. 2:36 My latest book, "Quantum Supremacy," has just hit "The New York Times" bestseller list. 2:43 Just today-- [APPLAUSE] --it hit "The New York Times" bestseller list. [APPLAUSE] 2:50 And the previous books, you can see here, they're all "New York Times" bestsellers, for example, "The Future of the Mind." 2:56 I talk about the fact that in the future, digital will gradually be phased out, 3:02 that digital will be replaced by quantum and by neural transmissions. 3:08 That is, directly we will communicate from the brain to the internet-- not anytime soon. 3:14 We're talking decades in the future. But the future of the internet will be quantum. And it'll be neural. 3:22 And this means, of course, that we physicists can now probe the thinking brain with MRI scans. 3:28 We can now see blood flow in the brain as thoughts are created. For example, we can now show that certain old wives' 3:37 tales are correct. It's an old wives' tale that everybody knows that, when a man talks to a pretty girl, 3:45 he starts to act stupid. Well, on a brain scan, we can actually see that effect, OK? 3:52 It's been published. What happens is, when a man sees a pretty girl, blood drains from the prefrontal cortex, 3:59 and he starts to act stupid. Actually, you can see that now with brain scans. 4:05 Anyway, these are some of the books that I've talked about. "The God Equation" is what I do professionally for a living. 4:11 I work in something called string theory, which we think is the theory of everything, 4:17 the theory that eluded Einstein, the theory of everything. When I was eight years old, something 4:24 happened which changed my life entirely. When I was eight years old, all the newspapers 4:30 ran a picture, a picture of a scientist's desk. And the caption said, a great scientist 4:37 could not finish this book. So on the desk was a book. 4:43 And it said, the greatest scientists of our era could not finish this book. 4:49 Well, I was fascinated. What could be so hard that a great scientist could not 4:54 finish? Why didn't he ask his mother? Why didn't he go to the library and just look up the answer? 5:00 So over the years, I would go to the library. And I found out that this man's name was Albert Einstein. 5:09 And that book was the unfinished "Theory of Everything," 5:14 an equation no more than 1-inch long that would allow us to, quote, "read the mind of god." 5:22 Well, we think today we have it. It's called string theory. I'm the co-founder of one of the main branches of string theory, 5:29 string field theory. But it's too difficult to solve with the human mind. 5:34 We have the equation. But the equations are so powerful, we cannot solve them analytically. 5:40 So that's why I got interested in quantum computers because quantum computers may be powerful enough 5:48 to solve the theory of everything, to give us an understanding of why 5:54 we had the Big Bang, why we have the universe, why are we here. 6:00 We may be able to answer that question with a quantum computer. So let's now begin at the beginning. 6:08 In the year 1901, in the Mediterranean ocean, 6:13 divers found a shipwreck, a shipwreck that dated back 2,000 years into the past. 6:21 And they found this thing on the left. It was encrusted with coral. They thought it was a piece of junk. 6:27 But then they looked closely. By removing the coral and the debris, they realized it was a machine, a machine that shouldn't exist, 6:37 a machine that was 2,000 years more advanced than its time. It was a computer on the bottom of the Mediterranean ocean. 6:47 So scientists came to look at this thing, X-rayed it, and then reassembled this device. 6:55 And they realized, oh, my god, 2,000 years ago, the ancients 7:00 created a computer. It is the most advanced piece of human machinery 7:07 in thousands of years. It tracks the motion of the Earth, the moon, Mercury, Venus, Earth, Mars, predicts eclipses. 7:16 It gives you a handle on the universe itself. Who created this? 7:21 We don't know. But we think it was supposed to be a coronation gift for Julius Caesar. 7:28 But a shipwreck took place, and it wound up on the bottom of the Mediterranean ocean. 7:33 So for the next 2,000 years, we roamed in darkness, 7:39 creating analog computers, computing on sticks, computing on beads, computing on hand-cranked mechanical 7:47 devices. We were rediscovering what the Greeks had already worked out 2,000 years ago. 7:54 These are analog computers computing on gears, levers, and pulleys. 8:00 And then, late in the 1800s, England was rising as a great maritime power. 8:07 They needed to calculate interest rates. They needed to calculate navigational charts. 8:13 They had to map the heavens so that ships can then navigate. So Charles Babbage, shown here created 8:21 a modern, analog computer. But you needed somebody to program it. 8:27 So Lady Lovelace, a member of the aristocracy, was curious about this machine being 8:32 built that could track the stars, that could calculate interest rates, that could calculate commerce. 8:39 And she was the world's first programmer. She wrote a program to compute the Bernoulli numbers. 8:47 Now, his machine, his final machine, was never built. He ran out of money. 8:53 He got involved with disputes. So later, many decades later, we rebuilt 8:59 the machine of Charles Babbage. He's the father of the modern computer, 9:05 father of the analog computer. This invention here, he never finished. 9:10 And then we had World War II. All of a sudden the Nazis were communicating 9:16 with this far-flung empire with a code called Enigma. 9:22 The Allies captured one of these machines. And they realized, oh, my god, the Nazis 9:28 were communicating with their war machine using a code that could not be broken. 9:34 So what happened was they gave the job to a mathematician. 9:39 Alan Turing, shown here on the right, was given the job to lead a group to crack the Nazi code. 9:46 And there's even a movie about it called "The Imitation Game" on the left. This group of mathematicians were 9:54 able to not only crack the code, but they even began the process of systematizing 10:00 the laws of artificial intelligence and computation. Before then, it was a question of amateurs 10:08 just dabbling in coding, dabbling in mathematics. What Alan Turing did was he codified 10:15 the laws of computation through what are called digital computers. 10:23 His Turing machine, shown here on the right, uses an infinitely long tape with zeros and ones, zeros 10:30 and ones, binary, with a processor shown in the middle, which takes a 0 10:36 and converts it to a 1 or another 0. And these rules on the left are the rules of computation. 10:43 All of a sudden, this became rigorous mathematics. So Alan Turing is the father of artificial intelligence 10:51 and the father of modern computation. And these are the machines that he built 10:57 that cracked the Nazi code. Historians believe that he shortened the length 11:03 of World War II by two years. World War II could have ended in 1947 11:10 without the work of Alan Turing. He cracked the Nazi code, and he created the Turing machine. 11:17 But it's a sad story. Years later, his work was classified. 11:23 And the people of England and the world did not know that he helped to win World War II. 11:29 In America, we celebrated the people at Alamogordo that built the atomic bomb. 11:34 But in England, Alan Turing was a complete unknown. And then, one day somebody burglarized his home. 11:42 The police came, and they found out he was gay. And they arrested him. 11:48 And they put him on trial. And they gave him a choice. 11:54 One of the options was to be injected with sex hormones to basically feminize him. 12:00 He grew breasts. He became very depressed as a consequence of these chemical treatments given to gay people who were gay. 12:08 And he committed suicide. He drank some cyanide. Actually he ate an apple laced with cyanide, 12:16 took a bite out of it. And we think that's how he died. Some historians say that that is the symbol of Apple computers. 12:26 The Apple computers, in some sense, could be dedicated-- the symbol of Apple computers 12:31 could be dedicated to the memory of Alan Turing, one of the greatest scientists of our time, 12:36 the father of artificial intelligence, the father of modern computation who invented the Turing 12:42 machine, which is the basis of the second era of computation. 12:47 The first era was analog computers, computing on sticks, computing on levers and pulleys and gears 12:54 and turning the crank. The second is based on electricity, on vacuum tubes 13:00 and then transistors to the point where now you can pack a billion transistors on a little chip. 13:07 But then the question is what's beyond that? What is beyond digital? 13:13 Well, take a look at this. This is Moore's law, which says that computer power doubles 13:18 every 18 months. It's held, as you can see here, since World War II, and even before that. 13:25 If you go to mechanical computers, analog computers, Moore's law goes back over 100 years 13:31 into the era of sticks and levers and gears and pulleys. But all things must pass. 13:38 This too shall pass. It turns out that transistors today, 13:46 the smallest ones can be about 20 or so atoms across approximately. 13:51 It's only a matter of time before transistors are 5 atoms across. At that point, all hell breaks loose. 13:59 At that point, Silicon Valley could become a Rust Belt, a monument to obsolete technologies. 14:06 That's why Silicon Valley is desperately working on the next generation beyond silicon. 14:15 Silicon technology will be exhausted when we hit about five atoms across. 14:20 At that point, the Heisenberg uncertainty principle kicks in. You don't know where the electron is anymore, 14:26 and it short circuits. Heat generation, leakage will kill Silicon Valley. 14:34 So Richard Feynman, after World War II-- he was one of the people who helped to build the atomic 14:39 bomb-- said, we have to go beyond digital computers. 14:46 Mother Nature does not use digital. Digital is alien to Mother Nature. 14:54 Zeros and ones, zeros and ones. Who uses zeros and ones, zeros and ones? 15:00 Humans, but not Mother Nature. What Richard Feynman said was nature is quantum mechanical. 15:08 Nature believes in electron waves, the uncertainty principle, the Schrodinger equation. 15:14 Look on the right. That's how a physicist looks at a hydrogen atom. We don't see a hydrogen atom as zeros and ones, zeros and ones. 15:23 We see them as waves, electron waves, a new way that Mother Nature uses to do computation. 15:31 When you walk outside and you see the trees, the leaves, 15:37 you see vegetation everywhere, do they use zeros and ones, zeros and ones? 15:43 Is that how Mother Nature creates the world around us? 15:48 No, everything is quantum mechanical. And so Richard Feynman said, it is only a matter of time 15:54 before we leave the digital era and enter the next era, the quantum era, when we compute on atoms. 16:04 Now, it's not easy to compute on atoms, but that's the future. That's the way Mother Nature does it. 16:11 And you have to have quantum computers to understand the quantum laws of life. 16:18 So let's do an elementary understanding of why quantum computers are so powerful. 16:24 Let's say that this is an atom. An atom spins. A spinning atom is like a magnet. 16:30 So it spins up in a magnetic field. Or it could spin down. So in this way, we have two ways of calculating a number. 16:40 An atom can spin up, or an atom can spin down. So that, in some sense, is the basis 16:46 of our civilization today. Things can spin up, or things can spin down. 16:52 But in reality, atoms can spin in any orientation whatsoever. 16:58 Now, how many more orientations are there than up or down? 17:05 How much more complex is the direction of an atom if it can spin in any direction? 17:12 You realize that, if you can compute in any direction, you are infinitely-- 17:19 infinitely more powerful than computing up and down, 17:24 up and down. Not only that, but your states, when 17:31 you rotate in any direction, you calculate in these states simultaneously. 17:37 Now, that violates common sense. Everything you've learned about the world says that you cannot 17:44 be two places at the same time. Your parents told you that you cannot be two places 17:50 at the same time. Well, we lied to you. Mother Nature is everywhere at the same time. 18:00 Let's take a look at a maze. If a maze is digitized, a mouse on the upper left 18:06 can make decisions to go left, right, left, right to map out all possible paths through a maze. 18:14 That's time-consuming. How many paths are there? There could be hundreds, thousands 18:19 of paths in a simple maze that a mouse has to navigate. At each juncture, the mouse has to say, left or right? 18:28 Left or right? And how many paths are there? Potentially hundreds, thousands of paths. 18:34 In a quantum computer, the mouse surveys all paths 18:39 simultaneously. Let me repeat that again. The mouse surveys all paths simultaneously 18:50 to pick out the correct path. Now, you may say to yourself, that's impossible. 18:55 That violates common sense. Common sense says you go one at a time, one at a time. 19:02 You mean to tell me that I can split it in half, that I can be in many states at the same time? 19:08 And the answer is, yeah, that's what we're talking about. You can be in multiple states at the same time. 19:16 And that is the power of quantum computers. Not only that, but these atoms can talk to each other. 19:24 This is called entanglement. And they can talk to each other faster than the speed of light. 19:29 Of course, the information traveling faster than the speed of light is not usable information. 19:34 But the usable information travels below the speed of light. And that is another reason why these computers 19:41 are more powerful than any digital computer. Now, these things exist. 19:49 We're not talking science fiction. And in fact, at the end of the month I'm flying out to Santa Barbara for 60 minutes. 19:57 And we're going to film. We're going to film the quantum computer that your company has built in Santa Barbara. 20:05 This is just one of several different kinds of quantum computers. Why does it look like a chandelier? 20:13 These are cooling pipes. These are not the quantum computer at all. [CHUCKLES] This is not really the quantum computer. 20:20 Look at the very bottom. That's where the quantum computer is. The quantum computer computes on an object 20:26 about the size of a quarter. The whole assembly is like the size of a suitcase. 20:31 Everything else is cooling pipes. Why? Because the slightest vibration, somebody sneezes 20:40 in another room, somebody burps, a car backfires, and it could upset the calculation. 20:47 Errors build up. And this is one of the reasons why this technology is not yet 20:53 ready for prime time. But about two or three years ago, two groups 20:59 created quantum supremacy. Quantum supremacy is the point at which 21:04 a quantum computer exceeds the power of a digital computer. And that was reached by two groups, one in China 21:13 and the other one, Google. Quantum supremacy has been attained 21:19 for certain discrete calculations. Now, an all-purpose quantum computer that you can program 21:27 does not yet exist. But that's the race. There's a race now between the Chinese, Google, IBM. 21:37 There's a race between all the major players of Silicon Valley, realizing that this is, 21:43 quote, "the next big thing." And how do the Chinese do it? 21:50 The Chinese do it not with electricity, not with electrons, but with light beams. 21:55 Light beams are polarized. Light beams-- like when you take sunglasses, sunglasses have striations on them, 22:03 let's say vertical striations, so that the only light that enters your eye vibrates up and down. 22:10 Light that vibrates to the side does not enter your sunglass. And that's how sunglasses work. 22:16 Well, that can be used to make a transistor, an optical transistor. 22:21 And with an optical transistor, you can make a quantum computer. 22:26 This is the Chinese quantum computer. It doesn't look like a chandelier. That's what the American version looks like. 22:33 This is the Chinese version. Look carefully. What you see are mirrors. 22:38 A mirror and a piece of glass can be a beam splitter. And what is a transistor? 22:44 A transistor is a way, in some sense, to control the beams of electrons. Here, these are beams of light. 22:51 And so the leaders in this race-- there's a race. And the leaders of the race are, one, the Chinese. 22:58 And then in America, we have Google, IBM, Microsoft, everybody-- 23:03 Honeywell. You name it, everybody is jumping in the game. What's at stake? 23:09 The world economy. The world economy today depends upon digital computers. 23:15 They will eventually become obsolete. When, we can't say for sure. But Moore's law will eventually flatten out. 23:22 It's beginning to flatten already. You can see it. At Christmas time, Christmas presents 23:28 are not twice as powerful as they were the previous Christmas. Now, let me ask you a question. 23:33 Would you upgrade at Christmas time? Would you upgrade knowing that your computers are just 23:39 as powerful as they were the previous Christmas? This could send shockwaves through the world economy, 23:46 realizing that computer power is stagnating, stagnating in the digital era. 23:53 So how will we communicate with a quantum computer? The quantum computer will probably be in the cloud. 24:01 They probably need a lot of cooling systems to bring it down to near absolute zero. 24:06 But you will communicate using probably a digital access 24:12 to a quantum computer in the cloud. This interface could be in your wristwatch. 24:19 It could be in your earrings. Or it could be in your contact lens. This is internet contact lenses, where you can access 24:27 the internet by blinking. And if the internet is in your contact lens 24:35 communicating with a quantum computer in the cloud, who will buy these things? Well, college students studying for final examinations-- 24:44 [LAUGHTER] --will be among the first to buy internet contact lenses. 24:50 They will blink, and all the answers to my exam will be right there in their contact lens. 24:56 Who will also buy them? These contact lenses will also identify people's identity. Just by looking at them, you'll know who they 25:03 are, what language they speak. It'll translate these languages. For example, let's say you're on a date, OK? 25:11 And your date says that he's rich, single, powerful, 25:17 and available, but your contact lens says, no, he's a loser. [LAUGHTER] 25:22 Child support payments-- this guy, stay away from this guy. He's poison. 25:28 Very important that you know who you're talking to instantly. Let's say you're looking for a job, 25:34 and you're at a cocktail party. And there's some very important people at that cocktail party, 25:40 but you don't know who they are. In the future, you will know exactly who to suck up to 25:46 at any cocktail party. Very useful. And these things actually already exist. 25:51 One contact lens gives you a golf score, for example. Eventually, you'll download the entire internet on your contact 25:59 lenses or your wristwatch or earrings or whatever. Now, what else can you do with this? 26:04 As I said before, the greatest consumer of quantum technology is Mother Nature. 26:11 You go outside. You see photosynthesis. You see leaves, trees, agriculture. 26:17 You see the variations of life on the Earth. All of it is a benefit from the quantum theory. 26:25 Nowhere do you see zeros and ones, zeros and ones, zeros and ones. Photosynthesis is a quantum process, 26:32 taking light, photons from the sun, combining it with carbon dioxide, 26:39 and creating oxygen and sugars. This is why you can breathe. 26:45 This is why humans can exist. We are benefits of a quantum process 26:50 that is beyond the capabilities of our most advanced chemistry. 26:56 In other words, we have to follow Mother Nature. And who else is interested in this? 27:02 D-Wave technology in Canada is already marketing quantum computers. 27:07 They're kind of primitive. They can only do minimization and maximization programs. But they're being sold commercially. 27:13 The aerospace industry is interested because the aerospace industry wants to create supersonic transports. 27:20 Remember that we used to have a supersonic transport called the Concorde? It was a failure. 27:26 Why? They had 1960s technology to analyze air flow. 27:33 Now, [CHUCKLES] 1960s technology is a dinosaur era. As a consequence, the Concorde created a sonic boom, 27:41 a sonic boom so great that it would shatter the windows in your house. So who wanted a supersonic transport overhead? 27:50 Nobody. The United States outlawed them, so it was a financial failure. 27:55 Now we have supercomputers. We can model airflow over the wings to reduce the sonic boom. 28:04 So supersonic transports now are hot business. They are the next chapter in aviation. 28:11 In the future, you'll have breakfast in New York. You'll have afternoon tea in Tokyo. 28:18 And you'll have dinner in New York again. So we're talking about a new era, a new era in space travel 28:25 even. Just last month, Elon Musk's moon rocket blew up on national television. 28:32 But-- but-- it is the future. We're talking about a reusable rocket that can go 28:38 to the moon, Mars, and beyond. This is an interplanetary rocket. 28:44 It's called the Starship. The original name for this rocket-- the biggest rocket in existence-- 28:51 the original name for it was the BFR, B for Big, R for Rocket. 28:59 [LAUGHTER] And you can imagine what the F stands for. It's now been renamed the Starship. 29:07 And Mercedes Benz is interested in this technology to streamline their cars to increase fuel economy. 29:15 So a lot of companies are jumping into the game. These quantum computers already exist. They're sold commercially. 29:21 They're not that powerful. But they will do maximization and minimization. And the solar industry is interested. 29:29 We've been talking about the solar era for decades. Ever since you were a child, we were 29:35 talking about the solar age. It never came. Why? People forget that Moore's law does not apply for batteries. 29:46 Batteries are the weak link. When the sun doesn't shine, the winds don't blow, 29:52 you lose your shirt. Look at this. In France-- acres and acres of solar cells. 29:57 The problem is the battery. So supercomputers can now do chemistry 30:04 in the memory of a quantum computer. Think about that-- chemistry without chemicals. 30:11 We're talking about a new era in science where we can model molecules. 30:17 We can't do that with ordinary computers. An ordinary computer is powerless to model 30:23 the intricacies of a chemical, of a molecule. But that's what we're talking about here. 30:28 Quantum computers can model quantum processes, including 30:33 to create a super battery. And this is the fertilizer industry. 30:40 About 100 years ago, the Germans were able to create artificial fertilizer 30:48 by taking nitrogen out of the air and creating factories, huge factories, 30:54 to create fertilizer. This was the first Green Revolution. This is the reason why you're here today. 31:01 50% of the atoms of your body are made possible by artificial fertilizer. 31:07 Let me repeat that again. 50% of every molecule in your body 31:13 has been made possible because of the Green Revolution. But this revolution is nearing its end. 31:19 They are polluting. They're inefficient. They use up 1% of the entire electric supply of the planet 31:27 Earth. Let me repeat that again. 1% of the entire electrical output of the planet Earth 31:36 goes into making fertilizer. We need a new way to do this. 31:42 Let's follow Mother Nature. Mother Nature creates fertilizers for free. 31:49 We have to have huge plants, gigantic plants absorbing 31:54 1% of the total electric output of the planet Earth to create fertilizer. 32:00 Mother Nature does it for free at room temperature. In other words, we need a quantum computer that 32:08 can duplicate this process. Now, on the left is the enzyme that makes it possible. 32:14 We've sequenced it. Look at that thing. That thing on the left makes life on Earth 32:19 possible by creating fertilizer. Can we use that, manipulate that using a digital computer? 32:25 No. Digital computers only work on zeros and ones, zeros and ones, 32:31 [CHUCKLES] zeros and ones. Look at that thing. There's no way that a digital computer can model that thing. 32:36 Except a quantum computer can. That's the power of quantum computers. 32:42 And now let's talk about cancer, Parkinson's. Let's talk about Alzheimer's disease. 32:47 Of course, we now have been able to sequence the DNA of plants, animals. 32:54 And what can we do with it? Well, not much. First of all, this is how we make the new next wonder drug. 33:03 Look at this thing. Thousands of Petri dishes shown here. 33:08 You put the germ in each one. And then you put a chemical in each Petri dish, 33:15 hundreds, thousands of them. And then what do you do? You cross your fingers. 33:21 You cross your fingers and hope and pray that one of them works and kills a germ. 33:26 Now, think about it. This is stupid. [LAUGHTER] [CHUCKLES] I mean, there's no rhyme or reason to this. 33:32 You just take all sorts of chemicals, and then you apply them to germs and cross your fingers 33:39 and hope that one of them kills the germs. This is how we make wonder drugs. 33:44 That's why they cost a billion dollars. It costs about a billion dollars to market one wonder drug. 33:50 This is how we do it. In the future, we'll do it in the memory of a quantum 33:56 computer. The memory of a quantum computer will now do chemistry. 34:01 Now, some people say, will this put chemists out of work? Well, chemists who do not use quantum computers 34:10 will be out of a job. Chemists who do use quantum computers will thrive, 34:16 and they'll have jobs. That is the future of quantum computers, to be used as a tool for chemists, biologists. 34:26 And look at Alzheimer's disease. Alzheimer's disease is incurable. 34:32 And it means that people in their 80s, about 50% of them, 34:37 have dementia. I repeat, about 50% of those people in their 80s have some 34:43 form of dementia and Alzheimer's. Why? Because of this. 34:49 That's the protein that gums up the brain. Now we realize-- using MRI and other chemical techniques-- 34:57 we now realize that this thing gums up the brain, causing Alzheimer's. 35:02 But there are two types of this protein. One bends to the right. 35:09 One bends to the left. It turns out the one that bends to the right kills you. 35:15 That's why we have problems with Alzheimer's disease. That's why your parents may have dementia. 35:21 But the one that bends to the left does not. You can have gum all over your brain, amyloid 35:28 proteins in your brain, and be clear-minded. Why is that? 35:33 It means there's not a one-to-one correspondence between the protein and Alzheimer's disease. 35:39 Why? Because only one variety causes it. With quantum computers, in the future 35:45 we may be able to separate the left and the right, curing Alzheimer's disease, the disease of the century. 35:54 And what else can we do with this thing? We can also use it to give unlimited power with fusion. 36:02 Mother Nature does not use oil and coal for energy. Mother Nature does not use uranium for energy. 36:10 In fact, the only place in the galaxy that we know of where uranium is used for power 36:17 is on the planet Earth. What does Mother Nature use? Fusion power. 36:22 And we're going to create fusion on the Earth. Just a few months ago in California, 36:29 we hit break even with a fusion plant. Why has it taken so long to create a fusion reactor? 36:36 Because of the instability of the plasma, the hydrogen gas. With supercomputers, with quantum computers, 36:44 we should be able to stabilize the gas to create an operating fusion plant to power the world, 36:51 to save us from global warming. And what else can we do with this thing? 36:57 This is the largest atom smasher on the planet Earth outside Geneva. This is the Large Hadron Collider. 37:04 On the right is what we do with it. What do we do with it? We smash atoms, hoping to recreate 37:11 the birth of the universe. And how do we model this? 37:16 With quantum computers. One of the first things we've done now is to put a quantum computer to analyze the right-hand side 37:24 when two protons are smashed together in order to create a theory of the universe. 37:31 In other words, the Big Bang, we think, shown here, will eventually be decoded by a quantum computer. 37:38 And hopefully it'll answer the question, why are we here? As I said before, I work in string theory. 37:45 This is the reason why I got interested in this. String theory is so powerful but so complicated 37:51 that the human mind is incapable of solving it. We think maybe a quantum computer 37:57 can solve this problem. And the aging process. 38:04 Why do we have to die? Well, there's a second law of thermodynamics 38:10 which says that in a closed system, everything eventually gets old, falls apart, rusts, corrodes, 38:17 and dies. In other words, it's a law of physics that you have to die. 38:24 But there's a loophole. There's a loophole in the laws of physics. Notice that I said that the second law of thermodynamics 38:32 says that, in a closed system, all things must eventually fall apart. 38:38 The key word is "closed." In an open system, where you have energy 38:45 from the outside, technology from the outside, you can, in principle, stop the aging process. 38:51 We don't have to die. For example, in a car, where does aging take place in a car? 38:58 Think about it for a moment. Where does aging take place in your car? The engine. 39:04 Why is that? That's where you have oxidation. That's where you have combustion. That's where you have moving parts-- 39:10 the engine. Well, what is the engine of a cell? Mitochondria. You now know where aging takes place in your body. 39:19 You now know why you will eventually die. And then the question is, can we go 39:25 around the second law of thermodynamics with a quantum computer by being able to correct the mistakes because 39:35 of wear and tear? That's how we repair cars. Why can't we repair humans the way we repair cars? 39:43 Well, maybe we can. And let's say a few things about cancer now. 39:52 By the time you have a tumor, you go to the doctor and the doctor says, it could be too late, 40:00 by the time you have a tumor, you have over a billion cancer cells growing in your body-- 40:07 a billion cancer cells growing in your body. In the future, we will do it with a blood test. 40:15 Already this year, for the first time in world history, for the first time, the FDA made it commercially available, 40:24 a blood test that detects 50 different types of cancers. 40:31 Let me repeat that again. Up to today, up to now, there was no way 40:37 to tell whether you had cancer or not until you found a tumor or some obvious symptoms. 40:44 And by then, sometimes it was too late. Now we have a blood test, a simple blood 40:51 test that can pick up 50 different kinds of cancers. In the future, this will be hooked up to a quantum computer 40:58 to detect hundreds, maybe thousands of different types of cancers growing in your body. 41:03 And where will we hook it up to? Your toilet. Ladies and gentlemen, this could be the cure for cancer. 41:12 Your toilet will pick up enzymes, proteins, cells from your body, from your bodily fluids, 41:20 send them to a quantum computer that will detect cancer and tell you that you have cancer maybe 10 41:28 years before a tumor forms. Ladies and gentlemen, this means that the word "tumor" 41:35 may disappear from the human language. You know, we don't say "bloodletting" anymore. 41:41 We don't say "leeches" anymore. That's an old technology that is shown to be obsolete. 41:48 George Washington, the father of our country, how did he die? He was bled to death-- 41:54 bled to death. We killed our president because of incorrect knowledge. 41:59 In the future, your toilet will [CHUCKLES] be your first line of defense. 42:05 Every time you use it, it'll be picked up by a quantum computer and tell you, uh-oh, you have cancer. 42:12 Do something. You have 10 years to do something. And who else is interested in this technology? 42:20 The CIA. Anything this powerful, even though we don't have it commercially available yet, 42:27 anything this powerful can break any known code. 42:32 How do you break a code? Well, let's say I have a number that is a hundred digits long 42:37 and I factorize it. I factorize it into two separate numbers. How long did it take for you to factorize 42:45 an integer 100 digits long? It may take you a few centuries-- 42:51 a few centuries to do that. That's how we protect the crown jewels 42:56 of our secrets, our nuclear codes, banking transactions. 43:01 The crown jewels, how do we protect them? By factorizing long numbers. 43:08 It takes centuries for a digital computer to perform this factorization process unless, of course, 43:15 you know the code, in which you can break right in. A quantum computer can conceivably 43:21 break into any known digital code. So who's interested in this? 43:26 The CIA. I was in Russia a few years ago speaking at a conference in Moscow. 43:32 [CHUCKLES] And yeah, the Russians are there, too. They too realize the power of what a quantum computer can do. 43:41 And let me now end on a few notes. First of all, how does it work? 43:47 It works because of the fact that you can be two places at the same time. 43:53 That is the power of quantum computers. Let's say I take an electron beam 43:58 and shoot it through two slits. On the right-hand side is the interference pattern because the electron beam will interfere 44:06 with the other electrons to create a pattern on the far right. OK, you got that? 44:12 Now let's shoot one electron-- [CHUCKLES] one electron through the double slit. 44:21 What's on the other side? You think that it's just going to be one dot. 44:28 One electron creates one dot, right? No. 44:33 What you find is that each time you shoot the electron through the slit, an interference pattern shows up where it impacts on the screen. 44:44 So in other words, the electron interferes with itself. Now, how can that be? 44:49 How can you interfere with yourself? [CHUCKLES] Because in some sense, 44:55 there is a parallel world that you are interfering with. In other words, you are two places at the same time. 45:03 This is the famous Schrodinger cat. A cat can be both dead and alive simultaneously. 45:10 And this is the reason why quantum computers are so powerful. They compute in all possible realities 45:16 simultaneously at the same time. And then the next question that everyone 45:22 asks me is, is Elvis Presley still alive in a parallel universe? 45:27 And the answer is, well, probably yes. There probably is a parallel universe where he's belting out hits still 45:36 because the universe splits in half, constantly splitting in half. 45:42 Now, I'm going to wind up. I once asked a Nobel Laureate to explain this in simple terms. 45:48 Steve Weinberg said the following. Imagine your living room, where radio waves from many countries 45:57 fill your room. Radio, Moscow, Havana, whatever, right? All these radio stations in your living room at the same time. 46:05 But your radio only picks up one frequency. Why? It vibrates in unison only with one frequency. 46:14 And that's why you hear only one station-- not an infinite number of stations, one station. 46:20 You got that? The wave vibrates in unison with your radio. 46:25 Now, replace the radio with electrons. All of a sudden, your living room 46:31 is full of different types of atoms, the atoms of dinosaurs, 46:36 the atoms of aliens from outer space, the atoms of pirates 46:41 all in your living room. But you have decohered from them. 46:47 You cannot shake hands with Elvis Presley, because he's vibrating at a different frequency than you. 46:55 This is the multiverse idea, the idea that reality is full of different parallel universes. 47:02 But you only vibrate coherently with one universe. 47:08 And that explains the power of quantum computers. They compute on parallel universes. 47:14 Where do you find them? Well, the first mention of a parallel universe was in "Alice in Wonderland," written by Charles Dodgson, 47:23 a British mathematician who wrote under a pen name, Lewis Carroll. Einstein talked about parallel universes 47:30 in 1935, introducing wormholes. And now Hollywood has discovered parallel universes. 47:39 The Oscars this year were dominated. All the awards went to a movie talking 47:45 about parallel universes. Well, I'm running out of time. So I'd like to introduce some questions. 47:51 So let me end on one final note. And that is, when I was a child my role 47:57 model was Albert Einstein. And my favorite Einstein story is this. 48:02 When Einstein was an old man, he was tired of giving the same talk over and over again. 48:10 So one day a chauffeur came up to him, and the chauffeur said, Professor, I'm really a part-time actor. 48:17 I've heard your speech so many times, I've memorized it. So why don't we switch places? 48:24 I will put on a mustache. I will put on a wig. I will be the great Einstein. 48:29 And you can put on my jacket and be my chauffeur. Well, Einstein loved the joke. So they switched places. 48:35 This went along famously until one day a mathematician in the back asked a very difficult question. 48:42 And Einstein thought, oh, the game is up. But then the chauffeur said, that question is so elementary 48:49 that even my chauffeur here can answer it for you. [LAUGHTER] OK, thank you very much. 48:54 I think we have time for a few questions. [APPLAUSE] 49:00 SPEAKER: Thank you, Dr. Kaku. I'll kick off a question or two here. First, we have microphones on both sides of the room. 49:07 Feel free to hop up to there. We're on a short timeline. But we'll get to some audience questions here soon. 49:13 Thank you very much. It's an inspiring view of the future. And so to kind of kick off some of our questions, 49:22 we're all kind of on this plane of existence together with limited resources and time, probably, on Earth. 49:29 For our practitioners and for folks in the quantum computing race, what would be your guidance on focus? 49:37 Do we try to focus in on the things that we know we have the largest impact in the short term, 49:42 by having not a general quantum computer but more of a specific thing, think like a GPU or TPU, 49:48 a very specific type of device? Or should we go all in and go for the generalized quantum 49:55 computer first? MICHIO KAKU: Well, I think we have to take a long-term view of this thing 50:01 that, if you put a crash program on one specific thing, maybe you're putting your money on the wrong horse. 50:07 It's a horse race. Each horse is pushing a different mode of physics. The Chinese are using optical methods. 50:15 We're using computer electron methods. But even then, there are different ways in which you can use electrons. 50:21 And it's not clear which of the different horses will win. It's not clear at all, because they're all quantum processes. 50:29 How many quantum processes are there? An infinite number of them, if you think about it. So I think what you've got to do is 50:35 you've got to hedge your bets. You've got to realize that you've got to put your money over a set of different kinds 50:42 of technologies because it's not clear which one technology will survive. 50:47 Each of these technologies is based on a quantum principle. But each of them has a potential defect. 50:53 You saw the optical computer. The optical computer does not have to work at near absolute zero, which is great. 50:59 But it's gangly. You saw how huge and how difficult it is to put all these mirrors in exactly the right alignment. 51:08 So each of these methods has a plus and a minus. And it's still too early to determine which 51:14 one will eventually win out. SPEAKER: Got it. So not placing any bets yet? MICHIO KAKU: Yeah. SPEAKER: [CHUCKLES] Awesome. 51:20 And then, for the next generation of folks that are coming up-- and I have children. I know you have children, as well. 51:28 We live in a world right now where there's a great plane, a spectrum of depth in science. 51:33 We have everything from something that might go out as a tweet today from someone who has an opinion all the way to academic peer-reviewed papers. 51:41 And you certainly have been able to build a career across the gamut there. What advice do you have for some of our Googlers 51:48 working with social platforms and online knowledge systems? How do we go and elicit the next generation of Dr. Kakus 51:55 to arrive? MICHIO KAKU: Well, when we are in college, 52:00 we specialize in a certain area. For me, it was quantum physics, for example. 52:06 But then if you want to communicate with your mother [CHUCKLES] or you want to communicate with your girlfriend, boyfriend, 52:12 or whatever, you just get these blank stares. We have to understand the language of people. 52:20 We have to be able to communicate with them because their lives are going to be dependent upon it. And that's how a democracy works. 52:27 A democracy works only if the people that are voting can make rational decisions. 52:32 And just remember that our future will be dependent upon voting-- a democracy. And politicians-- and politicians, of course, 52:41 would love to get their handle to pass all sorts of stupid regulations on things that are totally irrelevant but, of course, make them look good 52:49 and get them re-elected. So I think that, for example, on the question of chat bots 52:54 and things like that, I think it should be self-regulated, rather than having politicians come in, 53:01 which means that we have to talk to people in the language of people. So what I try to do is, instead of rattling off names, dates, 53:09 places, which go right over people's head, I try to talk about concepts and principles. 53:16 And then you see that these principles are universal. And they can be applied for many different purposes. 53:22 For example, when I talk to biologists, I talk about evolution-- one principle that explains so many different kinds of animals, right? 53:30 And when I talk about physics, I talk about relativity, motion. 53:36 I talk about rocket ships, clocks, things that people understand. So we have to learn the language of people 53:43 because they're the ones who determine our future because they're going to vote. [CHUCKLES] They're going to vote to make sure 53:49 that their interests are preserved. But if they don't know what their interests are, then we're in trouble. 53:54 SPEAKER: Great. Yeah, I think we can definitely get behind inclusive science and bringing everyone to the future 54:00 together. And then last, for me, before we go to our audience here, on my team, we have a tradition 54:06 of giving our speakers a magic wand here at Google. So I'm handing you the Google magic wand. 54:12 What would you prioritize for us to focus on? It can be in the quantum realm. It can be in the LLM world. 54:18 What would you do if you could wave the Google magic wand and get us all working in a common direction? MICHIO KAKU: Well, I like to look at history, 54:25 looking at technologies which dominate history. First was the Industrial Revolution in the 1800s. 54:31 Then came the electric revolution. So we had dynamos and electricity and so on, 54:37 and television, radio. Then we had the computer revolution. And now we're entering the artificial intelligent realm. 54:45 So we have to educate people on artificial intelligence because that's going to dominate our life. 54:50 It's going to dominate the market, the stock market. It's going to dominate culture. And already, people are sometimes 54:57 freaking out and sometimes overexaggerating some of these things. So we have to learn to speak to people's concerns. 55:04 And the concerns right now are, as we're entering the age of artificial intelligence, artificial intelligence will affect jobs, education. 55:12 It'll affect everything. And we have to be able to communicate that to the public so the public is not freaked out. 55:18 [CHUCKLES] And that's why I think it's important that we understand, first of all, that we're 55:23 entering the age of artificial intelligence. But we have to be able to then tell people 55:29 that this could be useful. It could create jobs. It could make life easier, life more productive, 55:35 life more efficient. These are the benefits of artificial intelligence. SPEAKER: Thank you. 55:41 Very timely. I think most of the folks in this room are working on an AI-related project this year anyways. 55:46 So that's really good. Thanks for the great leverage of that magic wand. First, I'll go here to one of our guest questions. 55:55 AUDIENCE: Hello. Good afternoon, doctor. Thank you so much for this presentation. That was really illuminating to see that kind of portrait 56:01 of technology. A lot of the things you describe sounds really fantastic. And I really wish them to happen that way, 56:07 to really make our lives better with minimal impact. However, I have to admit I'm a little bit concerned sometimes 56:12 about technology. We tend to see all the good it could do, and we don't necessarily stop to look at all the externalities and the potential negative impact. 56:21 For example, a lot of this technology, like with sensors in the bathroom detecting our health, that's great. 56:27 But we're going to use semiconductors that are going to have a lot of environmental impact. So my question to you is, while all of those things 56:36 sound great, do we necessarily have to try to maximize as much as we can technology? 56:41 Or would it be sometimes better or wiser to take maybe a pause and to wonder, it's not because we can do something as much as we can, 56:48 maybe should we do it? Or maybe should we take a broader picture, a more middle way to really benefit the greater good for most people, 56:56 including all the aspects, including environmental impacts? Thank you. MICHIO KAKU: Well, I think we definitely 57:03 have to look at the downside of technology because if we don't, then the politicians come up and monkey around and really make a mess out of things. 57:11 And that means self-regulation, when technologies become too advanced. And so I think, for example, take a look 57:18 at the movie industry. After the end of every movie, there's a little sign 57:24 that says, this movie was fake. All the actors are fake. All the dialogue is fake. 57:30 And you're a chump if you believe it's real. So every movie has a disclaimer. 57:35 So it's self-policing. The industry does not want governments to police which movies are good, bad. 57:42 They have a self-policing mechanism. Same thing with freedom of speech. What about freedom of speech? 57:48 Well, you cannot yell "fire" in a crowded theater. There are limits to free speech even. 57:55 And so I think that the industry has to mature to the point where, yeah, you're competing against the next guy. 58:01 It's a race against time. And you realize that if you fumble, then the next guy will grab your lunch for you. 58:07 Yeah, there's that, too. But you have to look at the bigger picture, too. And that is that, unless you begin 58:13 the process of self-regulation, then the industry gets looked upon adversely by the politicians. 58:21 And then it's political football. God knows where it's going to go. Or look at the Comics Code of the 1950s. 58:29 I still remember the time when people were saying comic books should be banned-- 58:34 this is after World War II-- because we're talking about violence. Well, the comic industry created the Comics Code. 58:40 That's a little symbol on the comic books saying that, yes, it's been approved by the Comics Code. 58:46 And that prevented the government from censoring and regulating the comic book industry. 58:52 So I think the computer industry is no different. That is, at a certain point, it's better to be self-regulating than have politicians do it 59:00 because right now people are a little bit afraid. They're afraid about what the impact will be on their jobs, their children's education, 59:07 stuff like that. And so I think we have to put that to rest by having the industry self-regulate itself. 59:13 And already, some of the leaders of these companies are meeting with the president pretty soon, which I think 59:19 is a good sign-- a good sign. So it means that, yes, the industry is looking at the ethical, moral dimension, as well. 59:27 AUDIENCE: Thank you. SPEAKER: Great. Thank you, Dr. Kaku. I know we have a lot of questions we'd like to ask you. 59:33 But you have a very tight schedule today. MICHIO KAKU: Yeah, maybe one more question. SPEAKER: One more? MICHIO KAKU: Yeah. SPEAKER: OK. AUDIENCE: Hi, I'd also like to thank you 59:39 for coming out and speaking to us in person here. I have a question that is simple but probably doesn't have a simple explanation. 59:46 You mentioned that we kind of already have a theory-of-everything equation, but it's just "too complicated" to solve right now. 59:53 What about it makes it too complicated to solve with our classical digital computers? 59:58 Is it like a P-versus-NP NP thing? Or what about the complexity of it needs quantum computers? 1:00:05 MICHIO KAKU: Well, the simplest problem with putting the theory of everything on a computer is that the theory of everything is not based on numbers. 1:00:12 It's based on super numbers, Clifford algebras. You can Google it. And you realize that-- 1:00:18 [LAUGHTER] [CHUCKLES] You know that super numbers cannot be easily 1:00:25 programmed in a computer program. A computer uses ordinary digital numbers, 1 plus 1 1:00:31 is 2, things like that. We use super numbers, Clifford algebras. And as a consequence, they cannot be put on a computer 1:00:39 very well. So a computer would go bonkers trying to solve string theory. 1:00:44 And that's what we want to do. We want to calculate our universe. Why are we here? 1:00:49 Why do we have stars, galaxies? It could have been something else. I mean, for example, in some universes, 1:00:56 protons are not stable. If protons are not stable, then everything collapses into a mist, a mist of electrons and neutrinos. 1:01:03 But here we are. We have stable protons. It's very difficult to get a stable proton. We've tried very hard. 1:01:09 So far, nobody has been able to show that a theory of everything gives you a stable proton. 1:01:14 In other words, reality itself should dissolve in most scenarios. And so we want to be able to calculate with string theory 1:01:22 to show that our universe is stable, so it doesn't collapse, and to prove that the proton is stable. 1:01:27 But nobody could do that. In fact, if any of you ever figure out why protons are stable, tell me first. 1:01:34 [LAUGHTER] And we'll split the Nobel Prize, you and me. OK, I have to go. 1:01:39 SPEAKER: Knowingly or not, I think you just put down the gauntlet here in a room full of smart engineers. So thank you for that. 1:01:44 Thank you for joining us today. And congratulations on your book's success already. We're looking forward to having you back here soon. 1:01:51 MICHIO KAKU: OK. SPEAKER: Thank you, Dr. Kaku. MICHIO KAKU: Thank you.

In fact, you will NEVER catch him discussing just how we can get out of our CURRENT mess, only of his dreams of a glorious future created by high technology. The fact is, simply by viewing the current rate of ecosystem degradation by human beings, we actually have very little time on the geological clock to even guarantee that we'll even be around to see the miraculous future visions Dr. Kaku so enthusiastically promotes. 4 Reply 2 replies @davidl6757 7 months ago Love it!!!

I discovered my curiosity about this topic as recent as fee weeks ago,- at its most! My journey began after I’d listened to one of Lex Fridman podcast episodes, and I’ve yet to listen to the episode where he interviews Professor Kaku! Every time I listen to professor Michio Kaku’s I’m completely captivated and blown away by his immense intellect and knowledge. it’s his ability to explain his field of expertise in laymen’s terms, which makes it possible for me as a newbie to make sense, comprehend what he says, I don’t know if the use of layman language comes naturally to him or is something he has developed over the years, in any way I’d like to propose that speaking in a way that is accessible to everyone is really powerful, and must be seen in the light of brilliancy! Anyone who like myself is new to an area where specific knowledge and expertise is required to be able to work in the field knows what it’s like listen to someone who doesn’t apply Professor Kaku’s layman language, it’s a struggle! A struggle defined as having to look up definitions every other word “the person” is talking. Hence my deep appreciation for Mr Kaku and his ability to formulate himself,- & his complex work, as well all the various challenging scientific theories and scenarios he presents in an easy,- & instant accessible format. Professor Kaku manages to explain the most profound, powerful l,- and the most complex of all complexities there is in our world today by his use of a layman terminology, a language that includes rather than excluding people like myself - so when I hear him describes something extremely complicated it still makes sense to me instantly,- & thus far - every time I’ve listened to him he has always presented what he talks about in this cohesive way and for that reason I’m immensely grateful.

Whichever it is, you will always find your way out, provided that the maze is designed to allow a way out. How? Start walking with your hand on one side of the wall (left or right) and keep it that way. You will go through all passages, taking a bit longer, but eventually you will get to the exit without fail.

When an object in a multidimensional space is replaced with a lower dimension, for example, when an object in a three-dimensional space is replaced with a two-dimensional plane, the parts that are not in contact with the two-dimensional plane exist as shadows. Have you ever found out that what you thought was 2D is actually a 3D shadow? In that case, S needs to consider the invisible dimension. 1 Reply @Andrew_EvsW 1 year ago (edited) What a great human being! 5 Reply 2 replies @claragabbert-fh1uu 9 months ago Transmutes? You might say that. I usually think of it as "processes". Others regard it as "controls by logic". All together, it amounts to being that a quantum computer works by talking to itself; it arrives at answer BY the logic that we put into it in design of it's process, called an "algorithm"; ancients called it a song or a tune. The process is composed in relational definitions and is sequenced essentially by words that we use; we have already evolved into those words logic useful to us in thinking. We have represented that logic as alphabetic characters and punctuations and sentence syntax of word reference by function. So really, the quantum computer mimics our use of logic, but it uses signals of quantum bubble presence or collapse as its characters, and it does so very fast. In fact, by using words as titles for subroutines and functions, like titles of books, the computer, just like us, can create new dimensions in information processing, leaping far ahead in time to the answer because it can figure out how the answer behaves from any attempt that it figures out; instead of only finding an answer to a question as we ask it, it can find the answer to an easier question and then from there figure out what the answer is by changing to a more complicated question. So you see, the quantum computer is a language computer that works because Man has discovered logic and put logic into Man's languages; Man discovered logic BY paying attention to, remembering and considering God in all that Man did, over a VERY long time. The Universe taught God's logic to Man, who put it into language, then translated it into signals, notes and numbers that a computer could work with. Then we downsized the computer processor to qubit size (very few atoms at a time, as a bump on a chip) and downsized the "clock" to 1 or two atoms for VERY fast speed. The result was QUANTUM COMPUTER. Now you understand HOW it works, WHY it works, and HOW it came to be that way. It is easy to comprehend (get the general picture of). BUT, when you get down to atomic scale with electrons, simple things become VERY inordinately complicated, and nothing is obvious anymore without being proven. But because the speed increases so much, you can resolve the proofs against complications and still get the answer blazingly faster than if you yourself had to figure it out. This is a compliment, but you might think of it as talking to a (speed talking) South American or a Hindu or East Indian; such old societies have been talking about complex, ancient problems for so long they evolved everyday languages that really "cut to the chase". Every time I think about it, I am amazed and astonished at how BRILLIANT! ancient ancestral cultures were, especially compared to today. 1 Reply @ltavare 7 months ago will there be windows updates? 9 Reply 2 replies @jeffbguarino 10 months ago From the point of view of the electron in the double slit experiment, the whole universe has become a wave and the electron does not see a double slit.

The Enigma code was first broken by the Poles, under the leadership of mathematician Marian Rejewski, in the early 1930s. In 1939, with the growing likelihood of a German invasion, the Poles turned their information over to the British, who set up a secret code-breaking group known as Ultra, under mathematician Alan M. Turing. Because the Germans shared their encryption device with the Japanese, Ultra also contributed to Allied victories in the Pacific. See also Cryptology: Developments during World Wars I and II.

Instead, they represent probabilities of finding particles in multiple places in the FORM OF wave equations modeling fictitious particles called "calculons". They do this in an analog way using actual atoms. Actual atoms do NOT have multiple states or locations at 1 time; they have probabilities of finding things in any 1 place at any 1 time. 35 Reply 15 replies @ophthojooeileyecirclehisha4917 1 year ago thank you 1 Reply @usher-p 1 year ago i would have loved to watch this if i was 12 3 Reply 1 reply @mje19D 3 months ago So many holes in string theory.

When you study a proton, we are told they contain 3 quarks, and when you study the nucleus of an atom we are told that is where the protons and neutrons reside and is typically drawn as a group of spheres of one color or another all jumbled together. But what if the nucleus was more like a drop of water? We know water comes as a molecule, but when included in a drop of water individual molecules lose their identity, fluidly interacting with all the other molecules in the drop. So, I would suggest to apply that same grouping result to the items that make up the nucleus of the atom. Once included in the group, the different quarks quit acting like protons and neutrons and start interacting with all the members of the group. It then becomes the surface tension of the entire group that forces them to remain in the proximity of the nucleus. Reply @jamesgreenler8225 1 month ago Quantum computing might make it possible to use a directed energy of some sort to make a neural connection from one brain to another. This type of communication would theoretically eliminate any language barriers because the particular area of the brain involved automatically translates everything to something you understand. That's my theory. Something like blue tooth but more advanced than we have dreamed of.

However, he knows how to talk about a lot of it. 2 Reply @claragabbert-fh1uu 10 months ago Yes! I've explained how a quantum computer is like an atomic, electronic musical steel drum "computer". Now you know HOW it works. Let me explain WHY it works. So, you know that morse code communicates by short sequences of 2 characters (dots & dashes); this is just "binary" code based on 0 & 1. But also, a xylophone can compose meanings of signal in 2 ways: 1) by sequences of "lettered' notes that we are familiar with by assigning a letter to them. With this we can build words that we are already familiar with based upon the number of notes per measure of music (or cycle of computer system time). This is like the individual signals if quantum entanglement bubbles "measured" when they either collapse or are felt by the rim of the qubit. Or, 2) we can compose a tune as a sequence of note signals, and assign it to a word we already know, like the Title or Chorus of a song. This lets us compose subroutines faster by sets of words that we recall just from the title alone. This is like the path, algorithm or song/tune of the computer qubits "arrangement". So by binary we can represent numbers (or anything), and by signals of bubbles or their collapse we can compose words, phrases, sentences, paragraphs, stories subroutines. Now, resolving the answer becomes much like you interpretively reading a book. The computer does much the same, interpreting words as subroutines by manipulations of logic. The final answer is a composite signal that must be interpreted in the context of these definitions of signals, even like smoke signals. So a computer CAN think because it can be enabled to talk with words that we think with, as a propagation of AI into the language ... kind of like "Trick or Treat". Just watch out for the noise and the "dog doo" of power supply spikes .n.U.

In Spinors it takes two complete turns to get down the "rabbit hole" (Alpha Funnel 3D--->4D) to produce one twist cycle (1 Quantum unit). Can both Matter and Energy be described as "Quanta" of Spatial Curvature? (A string is revealed to be a twisted cord when viewed up close.) Mass= 1/Length, with each twist cycle of the 4D Hypertube proportional to Planck’s Constant. In this model Alpha equals the compactification ratio within the twistor cone, which is approximately 1/137. 1= Hypertubule diameter at 4D interface 137= Cone’s larger end diameter at 3D interface where the photons are absorbed or emitted. The 4D twisted Hypertubule gets longer or shorter as twisting or untwisting occurs. (720 degrees per twist cycle.) If quarks have not been isolated and gluons have not been isolated, how do we know they are not parts of the same thing? The tentacles of an octopus and the body of an octopus are parts of the same creature. Is there an alternative interpretation of "Asymptotic Freedom"? What if Quarks are actually made up of twisted tubes which become physically entangled with two other twisted tubes to produce a proton? Instead of the Strong Force being mediated by the constant exchange of gluons, it would be mediated by the physical entanglement of these twisted tubes. When only two twisted tubules are entangled, a meson is produced which is unstable and rapidly unwinds (decays) into something else. A proton would be analogous to three twisted rubber bands becoming entangled and the "Quarks" would be the places where the tubes are tangled together. The behavior would be the same as rubber balls (representing the Quarks) connected with twisted rubber bands being separated from each other or placed closer together producing the exact same phenomenon as "Asymptotic Freedom" in protons and neutrons. The force would become greater as the balls are separated, but the force would become less if the balls were placed closer together. Therefore, the gluon is a synthetic particle (zero mass, zero charge) invented to explain the Strong Force. The "Color Force" is a consequence of the XYZ orientation entanglement of the twisted tubules. The two twisted tubule entanglement of Mesons is not stable and unwinds. It takes the entanglement of three twisted tubules to produce the stable proton.

Rife with spelling errors: "Rusts Belt" "Turning Machine" 1 Reply @claragabbert-fh1uu 10 months ago No, it balances. Now you will understand why a quantum computer operates very much like a musical "steel drum". The "qubit" is like a mesa plateau of many atoms that raise it above the substrate surface. This makes the qubit like a mason jar in that it affixes the electromagnetic field of the mesa island to the upper rim of the qubit, like a soap film clinging to the mouth of a mason jar that you invert into soapy water, remove & set upright. The electromagnetic field, like the soap film, sets the tension within the qubit like a tight-walker's rope does. Now, the field (like a soap film) exerts influence upon the atoma in the qubit; it creates an "entanglement" or equilibrium among however many atoms that it takes to make a quantum, or electron circulation, (soap) bubble of the same tension as the field (film). This is how the rim of the qubit is made to feel the presence of the bubble inside. The tension of the field film establishes both the speed of the qubit switch, the size of its signal compared to "noise" AND the shape of the signal that the bubble makes when it collapses. This is important to know the purpose assigned to that bubble. All of this so far is like making one dented area in a steel drum that pings 1 musical note. The "computer" comes from linking these qubits together in sequences of connection that make a "song" or "program" that answers a question. This is done in 2 ways: 1) different size qubits (or the same size qubits) are placed in differing geometric patterns around each other, so they can handle different numbers of (inputs + outputs) that basically in math define a "word", meaning (characters + aspects of answer), which is the same as saying they do an "operation" of math or of relational truth called "logic". 2) then all or some of these qubits are linked to each other as needed by structures inbetween them that make fields between them, much like more soap films. This is like clustering a bunch of mason jars together into shapes, with just the screw part of the lid on each, and putting small magnets between only some of them. By designing these tension pathways of (magnet) films, we can make sequence circuits like mazes that solve problems "bit by bit". Doing this is like making a musical steel drum to answer a specific question. Ancients actually made steel drums AS computers TO model the stars in the heavens, to see how big a problem would become, and by THAT knowing that if they could solve it. Some steel drum musical tunes became their "program" to solve it. Today, the quantum computer leaps beyond that. By being atomic (quantum), it is fast, so it can resolve very complex problems with the blazing speed of an orbiting electron. By being electronic, meaning based on streams of electrons, we can reconfigure the computer quickly to resolve all kinds of problems with the same or with different programs. Steel drums can only solve a few problems at a time, beyond which we enjoy making noise. So THAT is how ancient knowledge became new ... AGAIN .U. Reply @robertwilliams5979 1 year ago A few corrections on the intro section: * The Antikytera mechanism shown at 6:30 was not a computer/ calculator in the sense we'd understand it, it's more like a very precise and sophisticated gearing set-up which modelled planetary motions to a high accuracy. The calculating machines shown at 7:35 serve entirely different purposes and are not "rediscoveries". * The machine shown at 8:45 is a difference engine, not the Analytical engine which Lovelace was writing programs for. Babbage's Analytical engine has never been built * Turing's work on computable numbers (including Turing machine) was done in 1936, before WWII and before anyone in England had heard of Enigma. Turing Machine is more of a theoretical device for analysis than a useful computer design. Turing's work in AI was after the war. * This machine shown at 10:55 is a Bombe, an electromechanical device for checking valid Enigma wirings, again not something we'd recognise as a computer. A programmable computer was invented at Bletchley Park by a different group and for a different cipher.
