Chapter 809: A Lesson on the Frontline of War

When it came to the knowledge about space tension, after deliberation, Yang Yuping decided to add an extra class to the military scientific research class, focusing on space tension.

Knowledge can always be turned into power, and even on the front lines of war, it is still important to take classes.

Admiral Rhodes passed the application for this class and recalled the students from the military scientific research class.

There are 37 students in the military scientific research class on the front line, but only 32 can be present, and the remaining 5 can only listen to the lectures online through the communication channel.

This class is held in the lab in Crater Mountains.

Before the class started, Da Liu and several other researchers were busy preparing the experimental equipment.

Due to the rush of time, even the seats of the students were not arranged.

When a student from a military scientific research class walked into the temporary classroom, Da Liu pointed out the door and said, "Make your own chairs and come in and sit, we are too busy here."

"Want to help?" Ye Zheyu was the first to arrive, and stepped forward to help.

"No, no, just find a seat and sit down. The class will start in about half an hour. The professor should be here soon." Da Liu pushed his glasses and began to fill a pot with a transparent liquid.

Ten minutes before the start of the class, 32 students from the military scientific research class arrived. Ten minutes earlier, the timing was very accurate.

After all, he is already a soldier in the army and has developed discipline.

With five minutes left, Yang Yuping straightened his clothes and walked in, and began to give a lecture: "Students, I never thought that one day I would teach you on the front line of the war.

"However, as a student of the military scientific research class, we should have an iron will. We are a military scientific research class, not only to fight for the fate of mankind, but also to continuously absorb knowledge for human scientific research.

"Military and scientific research, this is the real meaning of our class."

Having said that, Yang Yuping paused, opened the speech script he had prepared overnight, and got to the point:

"Today's lecture is about space tension and curvature drive. Research and hypotheses on space tension and curvature drive are not new. Scientists have put forward relevant views as early as the 20th century.

"Why there is such a class all of a sudden, it starts with Fang Yuan's newly absorbed abilities.

"'Super power characteristic evolution', the name of this ability, I named it, and that was more than 30 years ago.

"However, it is a pity that the "super power evolution" thirty years ago did not meet the "lightning speed", and there is no subsequent story.

"After testing the source, we discovered an interesting phenomenon. After the energy level evolution of 'Lightning Speed', a magical power appeared.

"According to Fang Yuan's own description, this magical power will pull him away.

"According to the normal power engine thinking, if you want to get the power to move forward, you need to move forward through propulsion.

"From the jet engine, to the chemical propulsion of the rocket, to the ion propulsion...all the power engines manufactured by human beings are propulsion test engines, and none of them can escape this category.

"Moreover, from the perspective of human science at this stage, the pulling force generated out of thin air is a phenomenon that violates science.

"After discussing with several old friends, we thought of a possibility, a possibility that can generate tension.

"If this conjecture can be confirmed, then it can be said that the material technology I am studying now will not be worth mentioning in front of this technology.

"Before talking about curvature drive, we must first talk about what is spatial tension.

"First of all, let's take the word 'spatial tension' apart. Putting 'space' aside, let's talk about 'tension' and what is 'tension'."

In such a rigorous science class, Niu Dazhi insisted on being skinny, and suddenly said: "A classmate of mine in junior high school is called Zhang Li."

Most of the military scientific research classes are students, young and lively. When they heard this, they wanted to laugh, but when they thought about how serious the class was, they held back.

Fang Yuan and the others turned their heads and cast their eyes at him, especially Eve, if they were usually at odds with him.

Yang Yuping was very kind, he laughed and said, "Okay, let's see what is this thing with the same name and surname as your junior high school classmate?"

At this point, Da Liu came up with a set of experimental equipment.

This group of experimental equipment is a transparent plastic tray, in which there are two one-dollar coins, and there are two bottles of transparent liquid next to it.

The liquid is filled with a sharp mouth bottle, and the liquid can be dripped out drop by drop.

"Let Liu do this experiment. If some students want to take a closer look, they can come up." Yang Yuping signaled Liu to start.

Da Liu took over the conversation and began to say: "Here are two one-dollar coins, which have been wiped dry and laid flat on the table.

"There are two bottles of transparent liquid, one bottle is water, the other bottle is hand sanitizer, I just poured it from the sink in the bathroom.

"Now, let's put water on these two coins and see what happens."

As he spoke, he dripped water on the two coins.

One drop, two drops, three drops...

The water droplets fall on the surface of the coin, but instead of flowing off the coin, it condenses on the surface of the coin.

As more and more water dripped, the water droplets gathered on the coin and formed a raised arc, covering the upper surface of the coin like a mushroom, but it just didn't flow down the coin.

Both coins had seven or eight drops of water, and the same thing happened. The water remained on the coins and did not flow down.

"Look, everyone, according to the common sense that water flows downhill, the water droplets should not stay on the coins. Why does this happen? Is this not in line with scientific laws?"

Da Liu guided everyone to think about the problem, and then continued: "Of course the experiment is not over here, what we will do next is a set of controlled experiments.

"I need to put a drop of hand sanitizer on one of the coins and see what happens."

As he spoke, he picked up the bottle containing the hand sanitizer and dropped a drop of hand sanitizer on the coin.

The hand sanitizer came into contact with the water on the coin, and in an instant, the water on the coin seemed to be punctured, and flowed down from the coin in an instant.

On the other side of the coin, the "mushroom" formed by water droplets is still staying on the coin.

Da Liu went on to say: "At this point, some students may have to say that maybe a coin can only withstand eight drops of water, and it won't be able to withstand one more drop.

"If there is no control group, there is really no way to rule out this suspicion. However, the rigor of the experiment lies in this."

As he spoke, he picked up the water bottle and continued to drip on the second coin.

Nine drops, ten drops, eleven drops...

Until the eleventh drop, the water on the coin still stayed on it, but the "mushroom" was getting bigger and bigger.

"Okay, I can only stop here, if it drips again, I really can't hold it anymore."

Liu made a joke, which made everyone laugh: "Why can water stay on the coin? The answer is tension, the tension of water."
