Now it is only 93 years before 2 1 12, so we can discuss how likely it is to realize Doraemon before 2 1 12. F. Fujio Fujiko graduated from the Electrical Department of Gorkon Institute of Technology in Toyama Prefecture, and has a solid foundation in science. He made a reasonable extension of props in comics and robot manufacturing based on certain physical principles such as Doraemon. This is not just a wild imagination.
For example, F. Fujio Fujiko cleverly designed the body structure of Doraemon.
In fact, Doraemon's integrated infrared eyes, super nose, radar beard and anti-skid hands have all been realized now.
For example, Doraemon's little round hand, the University of Chicago and Cornell University jointly invented Doraemon's spherical manipulator, which uses an air pump to pump pressure and keep things stable. Whether it is a small clip or a smooth egg, you can easily pick it up and even pour water to write.
As for the eyes that can see clearly in the dark, the technology of infrared thermal imaging night vision device is very developed now. The infrared thermal imager uses an infrared detector and an optical imaging objective to receive the infrared thermal radiation energy of the measured object, and the distribution pattern is reflected on the photosensitive element of the infrared detector, thus obtaining an infrared thermal image corresponding to the thermal distribution field on the surface of the object.
Generally speaking, infrared thermal imaging night vision device converts invisible infrared energy emitted by objects into visible thermal images. Different colors on the thermal image represent different temperatures of the measured object.
There are three main problems in creating Doraemon: the first is the brain that can have human emotions, the second is the anti-gravity technology that blends with the skin, and the third is the small nuclear fusion reactor that supplies power to it. If you want to consider his four-dimensional pockets, it is four.
We must first know where the IQ of the robot comes from, from Bayesian formula. Let me tell you what Bayesian formula is. To put it simply, if you like eating in a restaurant, you may like the food in this restaurant very much. In other words, when you can't accurately understand the essence of a thing, you can judge the probability of its essential attribute by the number of events related to its specific essence.
Artificial intelligence is not a person. It won't grow up in society like us. It has a conventional name for any object. We can think and judge things through our brains. It has no brain. Then Bayesian-Laplacian formula becomes the brain of artificial intelligence at this time.
So this is the case when it is applied to artificial intelligence. We showed artificial intelligence a map of a kitchen knife and asked it what it was.
Seeing the shape of a kitchen knife, it may be a metal product; One side is very sharp, which may be used to divide items; There is a handle at one end, which may be kitchen utensils. . . Finally concluded that it was a kitchen knife.
Artificial intelligence constantly collects the information it stores and uses it to infer whether the original probability is accurate. Every new inference reduces the scope of uncertainty, and thus draws a correct conclusion. So Bayesian-Laplace formula can be said to be the cornerstone of AI evolution.
There is also artificial intelligence to recognize our voices. We said a word to artificial intelligence. Assuming this sentence is a, artificial intelligence needs to determine which meaning e it appears to be the most reliable. That is, we need to calculate: P(e|a). According to the formula I gave above, we can draw the conclusion that:
P(e|a) ∝ P(e) * P(a|e)
Finally, artificial intelligence will determine what you mean and why many brands of mobile phone voice assistants often roll over, including Siri. This calculation is a problem.
Bayesian formula gives the robot the ability to think and judge, and deep learning on this basis gives the robot the ability to simulate and learn human emotions. From 65438 to 0956, Frank Rosenblat, an American cognitive psychologist, invented a method to simulate neurons based on neuron theory. Can simulate the way the human brain calculates. Just like we get data from our senses, these neurons can get incoming data and learn, so neural networks can make decisions over time.
But at present, the deep learning of artificial intelligence is still very primary. It does not have the function of simulating human emotions, but in the era of 5G Internet of Things, the intelligence level and judgment level of artificial intelligence will reach the same level as that of ordinary people, thus helping us to better realize the Internet of Everything.
The other is Doraemon's power system. The atomic furnace is a small nuclear fusion reactor. We must first know that nuclear fission is used in our nuclear power plant. If nuclear fission is used, the radiation problem will be unavoidable. Nuclear fusion can reduce radiation and reduce radiation hazards.
Nuclear fusion is that the nuclei of light element hydrogen combine with each other to form heavier nuclei with greater atomic mass, and at the same time release neutrons to generate huge energy. Let's take the principle of hydrogen bomb explosion as an example (high technology is used in war, this sentence is really not bad at all): D+T → he+N, where D and T are hydrogen isotopes "deuterium" and "tritium" respectively, He is helium, and N is the energy source of neutrons, such as stars.
Using nuclear fusion to provide endless energy is also regarded as a breakthrough to realize the next energy revolution. Different from nuclear fission, the nucleus of nuclear fission is massive and unstable, so as long as the environment is normal temperature and pressure, the fission reaction can be realized, and nuclear fusion needs to create a special high temperature and high pressure environment. .
At present, China is at the forefront of controlled commercial nuclear fusion, and China has completed the physical scheme of fast-fire laser nuclear fusion. 20 18, 1 12, EAST, an "artificial sun" device made in Hefei, completed the 100 million-degree operation of the plasma center for the first time. Last year, it successfully realized that the electron temperature exceeded 50 million degrees and the duration. This is also the longest plasma discharge with an electron temperature of 50 million degrees on the international tokamak experimental device as of February 2065438+2006.
China's superconducting device is one of the most possible ways to realize the application of controllable thermonuclear fusion energy. At present, China has made the fastest progress in controlled nuclear fusion technology in the world. In 20 16, scientists in China successfully operated this device for 60 seconds, while foreign countries were still in the drawing stage. It takes about 60 years for nuclear fusion to reach the controllable commercial stage, and it takes about 100 years to realize a small nuclear fusion reactor.
Nuclear fusion research is also known as the artificial sun program.
The third is that Doraemon's body is wrapped in a special anti-gravity material. Because of the existence of this anti-gravity material, dirt and other things can't touch Doraemon. That is, floating on the surface. So even if it looks dirty. Wipe it and it will be clean. This is why it is obviously a robot. But you can also take a bath without shoes. Doraemon's feet actually don't touch the ground, so there is no problem of being dirty and wearing shoes.
We all know that gravity is produced by gravity, and its size is equal to the mass of the object multiplied by the acceleration of gravity g, that is, G=mg. People cannot get rid of the influence of gravity. The so-called anti-gravity system is to give an object a force outside the ground. When it is in the opposite direction to gravity, people can float.
The shoes in this state are in an anti-gravity state.
19 15 years, after Einstein put forward the theory of relativity, 19 16 years, on the basis of general relativity, Einstein put forward the gravitational wave conjecture, which is also the ripple effect of time and space. In layman's terms, it is the time and space in the universe that is elongated under the action of gravity, resulting in different dimensions of time and space.
In the last two years, Chad Hanna, an astrophysicist from Pennsylvania State University, discovered that two black holes extend indefinitely in the extraterrestrial universe. At first, the masses of these two black holes were 8 times and 14 times that of the earth respectively. But after gravitational stretching, the black hole began to merge into a huge black hole, and the mass of this black hole is only 2 1 times that of the earth, which is equivalent to twice as much.
What is lacking is that it bends in the universe through gravitational waves, causing ripples in time and space, just like throwing a small stone on the lake, which will produce endless ripples with the water level. This is completely in line with Einstein's gravitational wave effect. So there is no dispute about the existence of gravitational waves!
With the gravitational wave winning the Nobel Prize in the past two years, the technology of "anti-gravity" (which can shield the influence of gravity and make the spacecraft fly to the moon) described by British science fiction writer Wells has become active again, because gravitational waves can cause fluctuations in time and space, and it is reasonable to think that anti-gravity flight can be realized.
Anti-gravity technology has become a dream of human beings for more than a century. If anti-gravity can really be applied, it will definitely change the whole world. Cars, trains, ships, all the transportation systems you can think of can be driven by the energy obtained by the gravitational field.
Scientists even gave a specific time. In another hundred years, the anti-gravity era will come. It is basically consistent with the 22 nd century that Buxiong said.
At present, deep learning neural networks are used to simulate human emotions, which can make people cry and laugh like people. At the current development speed of AI, this can actually be achieved around 2050, but how to ensure that artificial intelligence can effectively avoid the negative energy of human beings when simulating human emotions, such as hatred, greed and evil. , is still a topic of constant debate in the scientific community. After all, people are unwilling to create robots to destroy themselves.
Now, we are also making a breakthrough step by step in the controllable commercial small nuclear fusion reactor, which is a technology that human beings must break through. With the continuous depletion of the earth's resources, nuclear fusion has just solved such a difficult problem.
The same is true of anti-gravity technology, which will also lead a new generation of traffic changes. But the biggest headache at present is actually the four-dimensional pocket of Doraemon.
Humans are three-dimensional creatures and can perceive three-dimensional things at most. Four dimensions are understood as time and space including the time axis, and the time and space of human real life is four dimensions, which is also one of the hypotheses of relativity. As a successful physical theory, four-dimensional space-time is widely accepted.
It is still very difficult for human beings to explore four-dimensional space (also called four-dimensional space). After we enter the fourth dimension, all the three-dimensional rules no longer apply. Compared with our three dimensions, the biggest feature of four dimensions is that it has one more dimension, and that is time. Everything we see after entering the fourth dimension is broken down into countless lines. These things cross horizontally and vertically, and make a specific location point through the intersection of time and space.
For example, for example, we can never reach the speed of light. He only needs to fold the whole three-dimensional painting in half, and he can instantly reach the other side of the universe, far exceeding the speed of light. For example, we humans can't conquer the cancer so far. Humans who enter the four-dimensional space can directly take out the cancer cells one by one from our bodies. For these miraculous signs like gods, it is as simple as drawing a circle on a plane for human beings to enter the four-dimensional space.
But if we enter the four-dimensional space, our bodies are likely to be twisted and torn, because the distortion of time and space in the four-dimensional space is definitely more intense than that in the three-dimensional space, so if we enter, we will first face the problem that our bodies may be torn.
It is also interesting whether humans will enter high-dimensional space. For example, Professor li miao, a famous physicist in China, analyzed the process of three-body from a scientific point of view. He believes that according to physics, the human body is composed of molecules and atoms, and how molecules and atoms are stable is due to the electromagnetic force between the nucleus and electrons. But when molecular atoms enter the four-dimensional space, this electromagnetic force does not exist in the four-dimensional space, and people will disintegrate in the four-dimensional space!
In other words, only the soul can enter the four-dimensional space.
How to enter the four-dimensional space is more difficult than traveling through time and space, because we still have specific operation methods on how to travel into the future. In Einstein's special theory of relativity, when the speed of human beings reaches the speed of light, time can stop, and when the speed of human beings exceeds the speed of light, people can travel to the future. Of course, going back to the past is more difficult. You can study relativity by yourself. After all, Einstein did not give specific methods and steps.
Generally speaking, 2 1 12 is very likely to realize Doraemon's birthday, but it is very unlikely to travel in time and space with a four-dimensional pocket.
We have to admire F. Fujio Fujiko, who created the whole Doraemon world with profound scientific knowledge and rigorous attitude, and also made scientists eager to recreate the whole Doraemon world. The props in Doraemon also brought a lot of inspiration to realistic scientists. Promoted the progress of science and technology. All the above are personal opinions.
