#166 Sự Thật Nổ Não SS02E33: Siêu Máy Tính Lượng Tử! 😱😱😱

Hello, I'm Voi. Nice to see you again in the familiar video series, Brain Facts. Do you know how people grow carrots? Just like a picture. And just like a picture, how to say it right? Or where is the world's strongest computer so far? Welcome to Brain Facts season 2, episode 33. Super Computer Alphabet The main use value of a carrot tree is its core. It contains a lot of vitamin A, which is good for your eyes. But have you ever asked yourself what people grow carrots with? With leaves? It doesn't make sense. Or with seeds? It doesn't make sense either. Because a carrot tree only has one seed. If you use that seed to grow a new tree, you will still only get one seed. So why don't you use fertilizer? The answer is that people grow carrots with seeds. Now you know that carrots also have seeds. In fact, carrots are a two-year-old plant. Biennial plant. In the first year, the tree developed a place with no leaves, and no fat for its stem, to prepare for flowering and creating seeds. Thousands of new seeds in the second year. And now you know that the old carrot you've been eating is the stem of the carrot tree. People often think that Sydney is the capital of Australia, Rio de Janeiro is the capital of Brazil, or Tokyo is the capital of Japan. In fact, the capital of Australia is Canberra, the capital of Brazil is Brasilia, and the capital of Japan is... Wait a minute. It seems that Japan does not have a capital. In fact, although most of the research results on Google show that Tokyo is the capital of Japan, some articles on Wikipedia say that there is no law in Japan that states that Tokyo is the capital of Japan. Not only that, the Japanese constitution does not have any description of the concept of capital. This means that in theory or on paper, Japan does not have a capital. That's why people call Tokyo the capital in reality, the factor capital, not the capital according to the law, the dual capital of Japan. Speaking of capitals, while most countries in the world have a single capital, up to 16 countries currently own more than one capital. With the South African Republic, it is the country that owns the most capitals when there are 3 capitals, that is Pretoria, the administrative capital, Cape Town, the legislative capital, and the capital of the court. You see your neighbor waking up early every day at 6 a.m. You praise him for working hard, walking like a picture. Your neighbor answers you with a smile. Maybe you think it's a friendly smile. Actually, he smiles because you are praising him in an incorrect way on the paper. In fact, this saying is quite common in everyday life. Just like a picture with a picture of a car or a picture of a light sky means a picture. And the action of picking a picture means picking a picture. This is a rather absurd and meaningless saying if you pay a little attention. Therefore, the correct saying in terms of vocabulary and meaning in case you want to praise someone for something, in an even or even way, must be as even as a picture, that is, a picture of a car or a picture of a light sky. With pictures here, it means that the leaves or coconut leaves are put together into pictures, all in a hurry to set up the house. Similarly, the idiom very poor, is often used to describe the poverty of someone who is often misunderstood in terms of meaning. To be more specific, Mùng Tơi Trong Nghèo Rất Mùng Tơi is not just a leaf of Mùng Tơi that we often use to cook soup or to pick green Mùng Tơi in the poem Người Hàng Xóm by the poet Quê Mùa Nguyễn Bình. Instead, Trư Tơi Trong Nghèo Rất Mùng Tơi means a shirt made from grass used to cover the sun and rain of our farmers in the past. Still, the top of the shirt is folded so that the strings go through the neck and shoulder which is called Mùng Tơi. The idiom very poor, is often used to describe the poverty of someone who is often misunderstood in terms of meaning. To be more specific, Mùng Tơi Trong Nghèo Rất Mùng Tơi is not just a leaf of Mùng Tơi that we often use to cook soup or to pick green Mùng Tơi in the poem Ngheo Khổ Đen Mức means a shirt made from grass used to cover the sun and rain of our farmers in the past. Wikipedia Supercomputer is a computer with superior performance compared to other computers. The performance of a supercomputer is often measured by the Flops unit with a Flops Floating Point Operations Per Second which is equivalent to a Fibonacci per second. Simply put, it is a Fibonacci per second. Accordingly, today's supercomputers have the ability to process up to petaflops which is millions of Fibonacci per second. In fact, all supercomputers are in the top 500 of the world's most powerful supercomputers which are in the top 500. All of them have the ability to process up to 1 petaflops. The world's most powerful and smartest supercomputer until now in October 2019 belongs to the top supercomputer SUMMIT developed by IBM. It has a scale of 2,414,592 processing units from 9,216 IBM Power 9 CPUs and 27,648 NVIDIA TESLA chips. 2,801,664 GB RAM which is a random memory set with a memory set of 250,000,000 GB or 250 petaflops. All are scaled down to 4,608 nodes which is 4,608 smaller supercomputers with the size of a fridge and are linked together to operate as a single supercomputer. With such a scale it is easy to understand that SUMMIT has the ability to process up to 200 trillion petaflops per second in theory with the highest performance ever achieved in practice at about 148.6 trillion petaflops per second. To make it easier for you to imagine SUMMIT's computing power is equivalent to the power of about 1 trillion of ordinary computers or equivalent to 7.7 billion people on Earth. Each person performs about 26 trillion petaflops per second and is clearly strong enough to open millions of Chrome tabs at the same time to upload and use millions of Facebook accounts at the same time to set up millions of views at the same time or to play millions of Pikachu games with the highest graphics quality at the same time. However, trust me, you will not use a computer with maximum energy consumption equivalent to the energy consumption of more than 8,000 households up to 15 megawatts equivalent to 15,000 power cells per hour to do the above. Instead, a supercomputer worth about 200 billion dollars equivalent to about 4,641.7 billion petaflops per year will be used in complex scientific research to solve calculations that ordinary computers will take thousands or even millions of years to complete. For example, designing chemical formulas, discovering new materials, solving mysteries about transportation, studying heat energy, about space, about supernova explosions, learning more about the structure of the Earth's core, as well as imitating climate change on a global scale. Still related to supercomputers, maybe you have heard about the concept of quantum computers, which is defined as a device capable of performing quantum calculations, while Nona is a computer model with a completely different nature compared to classical models on ordinary computers. The most basic difference between a quantum computer and an ordinary computer is that while a classical bit, the smallest information unit that an ordinary computer can understand, can always only receive one of the two values, 0 or 1. A quantum bit, quantum bit, or qubit can be both 0 and 1 at the same time. It is worth mentioning that quantum computers are no longer a product of imagination or a device from the future. They are real and real monsters. Accordingly, although it has been around for a long time with the first commercial quantum computer named D-Wave 1 introduced to the public on May 11, 2011 with a price of $ 10 million, but until recently, the public could only really imagine the tremendous power of quantum computers when a group of researchers from Google surveyed a monster with a price of $ 10 million named Sycamore. Specifically, the group of researchers gave both Sycamore and Summit the strongest classic supercomputer at present and carried out a task named Random Circuit Sampling to measure the power of quantum devices like Sycamore. The result was that the quantum computer took only 3 minutes and 20 seconds to complete the task. Meanwhile, Summit needed at least 10,000 seconds ah, wrong 10,000 years to be able to calculate with the current formula. This means that in the above experiment, Sycamore was faster by 1.5 billion times and saved energy by 10 million times compared to the classic supercomputer model. And remember this is only a quantum computer at the experimental level. Speaking of quantum, this word itself also has a rather interesting connotation that it can transform any object into a more divine and supernatural object. For example, a cave and a quantum cave. Jumping with a quantum jump. World with a quantum world. Or reading with a quantum reading method. Quantum speed reading. Actually, on October 14, 2019, the Chinese Communist Party held a debate after the video of reading at a quantum speed was posted on the social network. The point that most viewers cared about was that children under the age of 2 were reading at the speed of a poem. According to the Chinese Communist Party, reading at the speed of a poem was the best way to understand the content of a book, even when it was written in foreign languages. Not only that, reading at the speed of a poem was the best way to understand the content of a book. It was the best way to understand the content of a book. It was the best way to understand the content of a book. It was the best way to understand the content of a book. It was the best way to understand the content of a book.
