Auditorium of the Faculty of Physics.

Li Zhen led a group of physics experts to examine and approve the materials submitted.

Compared to the Mathematics Prize, the Physics Prize is the one with the largest number of entries, and it is also the highest quality.

When I reported the materials, I brushed some people down. The kind of little trick that wants to mix up with the nomination award has all been brushed down. The only people who can report for Li Zhen and others to review and screen are those who really have some real kung fu.

Fang Hanxian picked up a paper and looked at it, and couldn't help but shine in front of him: "This is really unique. ”

Li Zhen walked over: "Do you have any gains?" ”

Fang Hanxian smiled: "This person proposed a very interesting law, I think it is more 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, scrambling to circulate this paper.

"The law of a thousand pounds?"

"What does that mean?"

"It's a bit of a tongue-twisting statement."

"Hey, that's interesting."

"Amazing, this law was discovered by him. We had an idea before, but it wasn't comprehensive, and in the end it was just an idea. I didn't expect someone to put it up completely. ”

"The Kyushu Academy of Sciences has made a plan before?"

"No, we've envisioned this before. It is mainly the pinion that drives the big gear, which is able to generate more force. Reduces the speed and converts it into more power. But it's not perfect. We only know this truth, but we haven't made a perfect idea. ”

"This law of jacks is not about gears."

"I know, it's the same principle."

“……”

The paper says:

"The law of a thousand pounds. Taking advantage of the characteristics of still liquid and pressure, it pushes more than 100 times the power of the prime mover with a small force...... After the pressure increase caused by any point in the incompressible stationary fluid due to external force, the pressure increase is instantaneously transmitted to each point of the stationary fluid......"

"The pressure of the liquid is consistent everywhere, so that in a balanced system, the pressure exerted on the smaller pistons is smaller, and the pressure exerted on the larger pistons is also higher, so that the liquid remains stationary......

Therefore, through the transfer of liquid, different pressures at different ends can be obtained, so that a transformation purpose can be achieved...... Converting the liquid principle into a mechanical principle, it can be obtained: the small bevel gear drives the large bevel gear, and the lifting screw rotates to achieve the function of lifting tension. According to the above principle, everything is universal, i.e., a smaller force is transmitted through a specific system of 'pressure increase', and the force is not only increased, but also reaches a force that is hundreds of times greater than the prime mover. This is the law of the jack. ”

According to the basic equation of static pressure (p=p0+ρgh), when the external pressure p0 of the liquid contained in a closed container changes, the pressure at any point of the liquid will change by the same magnitude as long as the liquid remains unchanged in its original state of rest. Therefore, in a closed container, the pressure exerted on the still liquid will be transmitted to each point at the same time at an equal value......"

After everyone rushed to circulate it, they all felt interesting.

This law of jacks is really fresh.

Everyone understands the principle a little, and it is more intuitive to use machinery as an example. It is the pinion that drives the big gear, the speed decreases, and the force increases exponentially.

But this specific principle is not perfect.

The law of jacks proposed by this scientist completely perfects this blank, and it can not only apply mechanical principles. It is even pointed out that stationary, incompressible liquids can achieve their purpose more easily and easily.

How to experiment?

This is not difficult for the students of the mobile college.

Everyone is a high-level intellectual, and after reading that paper, you can probably know the principle.

Several cylinders were found, connected by rubber pipes, and then connected by a universal valve to another separate cylinder.

After filling it with water, a simple jack appeared.

Even though the experiment has not yet been conducted, the physicists present know that this law of the jack is definitely true.

However, verification is still required.

After adding a plank to the phalanx of several cylinders, a weight of fifty kilograms was placed on the plank. Fang Hanxian pushed the individual cylinders with one hand, and while pushing the cylinders, the internal space was compressed, and the liquid was dispersed through the universal valve to the six neatly arranged cylinders.

Fang Hanxian was just a hand, and he didn't use much strength. But as it continued to be filled with water, the 50-kilogram weight was constantly lifted.

Those who don't understand are amazed to see it. The power of one hand poured water down, and it was easy to push a fifty-kilogram weight up?

There are those who do not believe in evil and stand on the planks themselves. At this time there was a weight of fifty kilograms on the board, and the weight of one more person.

But still, Fang Hanxian didn't use much strength, and with the continuous water injection, the weight of one or two hundred kilograms was lifted up lightly.

"That's amazing!"

"It's amazing."

"Tsk, that's amazing physics."

"A simple truth can do such an incredible thing."

"The law of a thousand pounds."

“……”

Li Zhen is also very happy, it is better to be happy alone than to be happy with everyone. It's not like people from the Kyushu Academy of Sciences are always at the top of science. He is more willing to see science for all, and he is more happy that new science is constantly emerging in this world.

Obviously, more than half of it has been successful now.

Li Zhenyi waved his hand: "The law of thousand catties has been moved into the pending area." Look at the back for the nominees or prospective winners, and then look back. ”

“……”

The law of jacks is just a small storm. Immediately, Li Zhen found a very interesting paper.

Looking at a paper in his hand again, Li Zhen was shocked to find that New Kyushu had unknowingly improved science to such a level. It's unbelievable.

In fact, if you think about it, you can see why.

There is no shortage of geniuses in the world. As long as the overall situation is on the right path, then geniuses can continue to emerge.

Li Zhen took the lead and spread a lot of basic theoretical knowledge of the Kyushu Academy of Sciences, and those who originally had high attainments but just wanted to go to archaeology began to learn from scratch. Each of them is an amazing and brilliant person, and after their thinking has been transformed, they have begun to learn to create on their own.

So the new Kyushu became vibrant, and the soil of science began to glow. Someone keeps coming up with a whimsical idea, and then by chance...... And so it went.

Hand is a physics professor at Fuxing University, who has a deep understanding of optics.

And this time, the title of the paper is "On the Convex Lens Imaging Technique"
