Auditorium of the Institute of Physics.
Li Zhen led a group of physics experts to review and approve the submitted materials.
Compared with the Mathematics Award, the Physics Award has the largest number of entries and the highest quality.
When submitting materials, some people were removed. All those who tried to trick themselves into winning nominations and awards were dismissed. The only people who can be submitted for review and screening by Li Zhen and others are those who really have some real skills.
Fang Hanxian picked up a paper and looked at it, and his eyes couldn't help but shine: "This is really unique."
Li Zhen walked over and said, "Anything gained?"
Fang Hanxian smiled and said: "This man proposed a very interesting law, which I think is quite interesting."
Li Zhen picked up the paper and looked at it, and couldn't help but raise his eyebrows: "Verify this law immediately."
Everyone gathered around curiously and eagerly circulated the paper.
"The thousand-pound law?"
"What does it mean?"
"It's a bit convoluted."
"Hey, that's interesting."
"It's amazing that this law was discovered by him. We had made assumptions before, but it was not comprehensive. In the end, it was just an idea. I didn't expect that someone would come up with it completely."
"The Kyushu Academy of Sciences has made any ideas before?"
"No, our Motor Vehicle Institute has made ideas in this area before. Mainly, the small gear drives the large gear, which can generate greater force. The speed is reduced and converted into greater force. But it is not perfect. We just know this truth , but no perfect assumptions have been made.”
"This thousand-pound law is not talking about gears."
"I know, it's the same principle."
“…”
The paper says:
"Thousand-pound law. Using the characteristics of stationary liquid and pressure, using a small force to push a force that is a hundred times more than the original force... When any point in the incompressible stationary fluid is subjected to an external force to generate a pressure increase, this pressure increase is instantly transmitted to all points of the stationary fluid. …”
"The pressure of the liquid is consistent everywhere, so that in a balanced system, the pressure exerted on the smaller piston is smaller, while the pressure exerted on the larger piston is larger, which can keep the liquid stationary...
Therefore, through the transmission of liquid, different pressures on different ends can be obtained, so that a transformation can be achieved... By converting the liquid principle into a mechanical principle, it can be concluded that the small bevel gear drives the large bevel gear and rotates the lifting screw. And achieve the function of lifting pulling force. According to the above principle, everything is universal, that is, a smaller force is transmitted through a specific 'pressure increment' system, and the force is not only increased, but also reaches a force hundreds of times greater than the original force. This is the thousand pound law. "
"As for the basic equation of static pressure (p=p0+ρgh), when the external pressure p0 of a liquid contained in a closed container changes, as long as the liquid remains in its original static state, the pressure at any point in the liquid will remain unchanged. Changes of the same size will occur. Therefore, in a closed container, the pressure exerted on a stationary liquid will be transmitted to all points at the same time with equal value... "
After everyone rushed to circulate it, they all found it interesting.
This thousand-pound law can be said to be really new.
Everyone has some understanding of the principle, and it is more intuitive to use mechanical examples. It is the small gear that drives the large gear, the speed decreases, and the force increases exponentially.
But this specific principle is not perfect yet.
The thousand-pound law proposed by this scientist completely completes this blank and can not only apply mechanical principles. It is even pointed out that static, incompressible liquids can achieve the purpose more easily and easily.
How to experiment
This is not a problem for the students of the Automobile Institute.
We are all high-level intellectuals. After reading the paper, we will roughly understand the principles.
Several cylinders were found, connected through rubber tubes, and then connected to another separate cylinder by a universal valve.
After filling it with clean water, a simple jack appeared.
Even though the test has not yet been carried out, the physicists present know that this thousand-pound law is definitely true.
But it still needs to be verified.
When several cylinders are arranged in a square array and a wooden board is added, a fifty kilogram weight is placed on the wooden board. Fang Hanxian used one hand to push a separate cylinder. While pushing the cylinder, the internal space was compressed, and the liquid dispersed and flowed to the six neatly arranged cylinders through the universal valve.
Fang Hanxian only had one hand and didn't use much strength. But as the water continued to be injected, the fifty kilogram weight was continuously lifted.
People who don’t understand are amazed when they see it. With the power of one hand, water was poured down, and the fifty kilogram weight was easily pushed up
Some people did not believe in evil and stood on the wooden board by themselves. At this time there is fifty kilograms of weight on the board, as well as the weight of a person.
But still, Fang Hanxian didn't use much more strength. With the continuous injection of water, the weight of one to two hundred kilograms was lifted up as if it was light.
"Amazing!"
"Amazing."
"Tsk, tsk, this is magical physics."
"A simple principle can actually do such incredible things."
"The law of a thousand pounds."
“…”
Li Zhen was also very happy. Being happy alone is not as good as being happy with others. It’s unreasonable for people from the Kyushu Academy of Sciences to always occupy the top of science. He is more willing to see science for all, and he is more willing to see new science emerging in the world.
Obviously, more than half of the success is now achieved.
Li Zhen waved his hand: "The law of a thousand pounds has been moved to the undecided area. Look at the back to see if it is a nomination award or a quasi-winner."
“…”
The thousand-pound law is just a small disturbance. Immediately, Li Zhen discovered another very interesting paper.
Looking at a paper in his hand, Li Zhen was shocked to find that New Kyushu's science had unknowingly advanced to such an extent. It's unbelievable.
In fact, if you calm down and think about it, you can know why.
There is no shortage of geniuses in the world. As long as we take the right approach when looking at the overall situation, geniuses will continue to emerge.
Li Zhen took the lead and spread a lot of basic theoretical knowledge from the Kyushu Academy of Sciences. Those who had high attainments but just wanted to go archeology started to learn from scratch. Each one of them is a talented person. After their thinking was transformed, they began to learn to create on their own.
Therefore, New Kyushu became full of vitality, and the soil of science began to be radiant. People keep coming up with wonderful ideas, and then by chance... they just come true.
The paper in hand comes from a physics professor at Fuxing University. This physics professor has in-depth research on optics.
The title of this paper is - "On Convex Lens Photography Technology"
