After explaining the "Super Alloy" series of materials, a few people took a few steps forward and suddenly saw a white platform and a suspended black stone!
This is the core combination in the center of the entire hall: the stone is gray-black and unremarkable, that is, an ordinary ore.
But, it's completely suspended in the air!
If you are uninformed, you will mistakenly think that this is anti-gravity technology, but in fact it is not...
What holds this huge boulder is just a small ring underneath, and this semi-metal ring is what humans dream of...
Superconducting materials at normal temperature and pressure!
The light of a piece of superconducting material almost covered up the seventeen pieces in the "Super Alloy" series, and even Dr. Rimbaud's face showed an embarrassment of fascination.
Superconductivity under normal temperature and pressure, the crystallization of science and technology across the ages!
Dr. Rimbaud is also really convinced. I don’t know how this epoch-making achievement and such ultra-complexity materials were developed...
There is also superconductivity at normal temperature and pressure in the materials of the Mars flying saucer, but it is all piecemeal, and the process is extremely complicated, and humans are completely unable to imitate it.
Just like primitive people faced with a modern laptop computer, there is no way to build an original one. This is entirely due to deficiencies in both theory and craftsmanship.
But now...inexplicably, I did it?!
A large group of scientists gathered around the boulder and discussed it excitedly, even shouting.
These are experts in electromagnetics and materials science. Their faces are flushed, they are making exaggerated gestures, and they are spitting out a lot of professional terms.
They deeply understand the epoch-making significance brought by superconducting materials!
This is truly superconducting under normal temperature and pressure! To be precise, it needs to be under standard atmospheric pressure and in an environment below 15 degrees Celsius to function.
But this is enough. This superconducting condition is not much different from normal temperature and pressure...
Many scientists who were observing superconducting materials for the first time were beating their chests in front of this huge stone, eager to study it immediately.
For them, it is still conceivable that the superalloy series will appear in the exhibition, but...superconducting?
It’s so unexpected!
They feel like they are going crazy.
It can be said that almost any cutting-edge technology in the future will require the support of superconducting materials. For example: controllable nuclear fusion technology, ultra-high-speed electromagnetic guns, high-power laser pulses, quantum computers, etc. Without superconductivity, these technologies will be just a mirror image.
, can only exist in imagination.
At room temperature, the best conductive material is metallic silver. The resistivity of silver at 20°C is 1.59×10-8Ω?m. However, this resistance is still too large for some ultra-high-power weapons-grade equipment.
As long as there is resistance, the conductor will generate heat. Heating is fatal to high-tech devices!
For example, weapons-grade laser pulse devices have instantaneous power of hundreds of millions of watts. Just a small amount of resistance will generate a large amount of heat, creating the risk of conductor melting. Such devices are unstable, affecting the final power and accuracy.
These problems can be completely avoided by using superconducting wires without resistance.
In addition, in addition to the "zero" resistance characteristics of superconductors, complete diamagnetism is also an important feature. This is also the basic principle of the levitation of this boulder!
Since a superconductor "does not allow" any magnetic field inside it, if an external magnetic field wants to pass through the inside of the superconductor, then the superconductor will inevitably generate an opposite magnetic field to ensure that the internal magnetic field intensity is zero, which forms a repulsive force.
This kind of repulsive force can be used to fight gravity!
When a magnet is placed directly under a superconductor and the magnetic field lines pass vertically through the superconductor, the superconductor will obtain a vertical upward buoyancy force!
There was once a movie called "Avatar". The movie depicted huge rocks floating in the sky, which were caused by room-temperature superconducting materials...
Superconductivity, the strongest bottleneck for mankind to move towards the era of electricity and magnetism, has been overcome with inexplicable ease, leaving many people with an unreal feeling.
Yu Yifeng and others were listening to the discussion of this group of scientists. Some people lamented the ups and downs of this arduous road, while others had a beautiful vision for the future... Many people felt that this road would take a long time and would continue for several more years.
Ten or hundreds of years later, it suddenly ended, which made people feel very dreamy.
Yes, very dreamy...
Everyone thinks so. In fact, current humans have never thought about overcoming this problem.
But now it happened suddenly and inexplicably...
The origin of superconductivity comes from 1911. Kamerling Onnes of Leiden University in the Netherlands accidentally discovered that when mercury is cooled to minus 268.98°C, the resistance of mercury suddenly disappears. This phenomenon is called a superconducting state.
Because of this discovery, he won the Nobel Prize in 1913 and kicked off the research of superconducting materials.
Now, more than a hundred years have passed, and people's progress cannot be said to be great. It is really disappointing to see that room-temperature superconductivity was unexpectedly conquered by a newly emerging genius when it was still far away.
Just like a twisting mountain road with no end in sight, scientists just want to spend hundreds of years running step by step towards the end. But someone suddenly stopped and used an airplane to directly cross tens of thousands of kilometers to the end...
Yes, that's it, that's how scientists feel...a dreamy feeling, and an inexplicable sense of emptiness.
The structure of this superconducting material is extremely complex, and a similar structure has never appeared before. It is a high molecular polymer with silver as the core. The molecular formula is ****, and it is a macromolecule composed of millions of atoms.
!
The most peculiar thing is that a hexagonal "high-speed channel" is formed between molecules, and electrons can pass through the high-speed channel quickly without any obstacles... thus forming superconductivity at normal temperature and pressure.
This is indeed the case simply explained, but scientific theory cannot be explained so simply.
This research report on superconducting materials is confusing, and the specific principles are also vague. Therefore, even the inventor himself does not know how this "high-speed channel" between electrons is formed, as if
Found it by accident...
But the report itself describes the manufacturing process of this superconducting material in detail, and after verification, it is indeed feasible.
When Yu Yifeng heard the scientists talking, he was also very interested in the inventor. Just like a blind cat encountering a dead mouse, could it be that he was lucky enough to solve this big problem?
Yes, it is so magical and weird...
However, the probability of this kind of thing happening is not to say that it will never happen. It can only be said that it is very, very low. It can no longer be calculated as one in a billion, but one in ten billion or one trillion! Just like a monkey acting randomly
It’s as weird as tapping the keyboard to type out a beautiful article!
“Do otakus change the world?”
"Perhaps I was guided by God to get such inspiration..."
Scientists are talking a lot...except for luck, there seems to be no other explanation.
Yu Yifeng frowned and looked at the personal information of the inventor and creator. This guy named "Zhang Peng" was a super otaku who usually worked as a researcher at the Huguang Supercomputing Center.
Yes, a researcher in information engineering! Not a researcher in materials science?!
Normally, this Xu Peng is unremarkable, but this time, he suddenly had an idea, or rather got it wrong, and researched this superconducting material across industries?!
I don’t know if it’s a genius or a stroke of luck?!
Very weird!
To the disappointment of many scientists, this otaku did not even attend this materials conference, choosing to stay in his own house and maintain a strange sense of mystery...
Yu Yifeng shook his head, feeling very confused.
He really had very little impression of Zhang Peng, not that he didn't know him, but he only knew this person.
Moreover, this guy was brought from the earth to the moon through the "Victory" spacecraft, and he was one of the hundreds of survivors who luckily escaped from the earth.
He thought about it carefully, and although he wanted to visit the Frankenstein in person, he resisted.
Everyone has their own secrets. Since Zhang Peng is willing to keep a low profile, let him keep a low profile.
It is impossible for him to rashly investigate a rising scientific star because of some doubts in his heart.
At least the room-temperature superconductor invented by Zhang Peng is indeed very, very beneficial to mankind. Maybe he just patted his head and had a flash of inspiration?
Didn't Newton discover the universal gravitation in a flash of inspiration?
As for scientific matters, who knows, maybe it’s just such a coincidence and luck...
