"Everyone is quiet. Today we invited Lin Feng, a famous professor from the Nanhai Branch, to give a lecture at our school. I hope that during the lecture later, everyone can abide by the classroom order and listen quietly."

At about two o'clock, Cao Wenyan walked up to the front desk and gave a prelude to the open class.

"Next, we welcome Professor Lin to the stage!"

Slap sex...

The applause was thunderous, like firecrackers, detonated throughout the auditorium.

Zhang Xiaojiang applauded, and his face turned red with excitement. He focused on the direction of the import and exit of the backstage, hoping to see the true appearance of his idol as soon as possible.

But when Lin Feng walked out of the background, Zhang Xiaojiang was stunned for a moment, and his mind felt like he was struck by lightning.

"He is actually him, he is Professor Lin..."

Similarly, all the students in the audience were shocked when they saw Lin Feng appear.

They thought Lin Feng was an old man in his seventies or eighties, but they didn't expect that he was so young.

He is so young that he is a professor, so amazing.

As for the portraits hanging in the classroom, can we take them seriously? Confucius is always an old man, Lu Shuren will always be forty years old, and Lin Feng's portrait is also an abstract painting of ink painting. I heard that this is privacy protection.

So when Lin Feng stood on the podium, everyone was so surprised.

Lin Feng stood in front of the microphone and was surprised. He glanced at the entire auditorium. There were many people. Not only were the seats full, but there were even many students standing in the aisle.

Judging from this scale, it is estimated that more than 2,000 people will be worth more than 2,000 people.

Everyone is so enthusiastic? It’s not that Cao Wenyan deliberately arranged someone to support him.

But none of these matters. Lin Feng cleared his throat and made a joke:

"Maybe many classmates think I'm a bad old man, I'm sorry, I disappoint everyone."

"I'm honored to come to Mecha University and tell you something about Mecha. This occasion is too profound. I don't think it's appropriate to have too profound theories, so today I will mainly talk about three aspects."

"One, the definition of mecha, two, the advantages and disadvantages of mecha, three, the prospects of mecha."

"First of all, let's talk about the definition of mecha."

"As students of Mecha University, we should first figure out what the mecha is, what the meaning of the mecha is, the origin of the mecha and the history of the mecha."

"The definition of mecha, literally, is the armor made by a machine, referred to as mecha, which is named according to the concept of consciousness. In fact, the word mecha is an imported product and does not have such a deep meaning, but one thing is correct. Mecha is indeed inseparable from the machine."

"I think the history of mecha can be divided into three stages."

"Mechanism, machine, mecha."

"In ancient times, the art of mechanism appeared. The art of mechanism was the prototype of the machine, but it could not be called a machine, because the art of mechanism has no own power, and it is all about borrowing power, human, material and natural power."

"It was not until after the steam engine was invented that the mechanism was installed with power and the heart was used that the mechanism had evolved into a machine."

"The mecha is a giant machine developed based on the machine to fight monsters."

...........

The origin and history of mechas are probably aware of the students who are working on them. Lin Feng said it just to lay the groundwork and deepen the impression.

What he is going to talk about is the second and third points.

"Second, let me talk about the advantages and disadvantages of mechas."

"Everything, every person, and everything is not perfect. Mechas are the same. Mechas have advantages and disadvantages."

"Mecha is an efficient and timely conversion tool that can quickly convert chemical energy into physical kinetic energy."

"Mecha is a rigorous and comprehensive science. Because of this, it intuitively reflects the biggest disadvantage of a science - no explosive power."

"A normal person has about twice the weight limit of weight carrying, for example, a person weighing 120 kg, his limit of weight loading is 240 kg. But this is just the conventional limit, and the real limit is unimaginable.

A few years ago, there was a news report that in a certain place, in order to prevent the floor from hitting his child, the mother used her body to support a floor weighing several tons. This completely broke the concept of conventional limits and should be called explosive power.

People have explosive power. If their normal power is only 70, then they can reach 100 or even more than 100. However, the mecha does not have explosive power. The power parameter is 100. Then, without changing the mecha parts, this parameter will always be frozen at 100."

"However, this disadvantage can also be regarded as an advantage. Because of this old-fashioned parameter, the battle becomes more formulaic and greatly reduces variable factors...."

In this paragraph, Lin Feng explained the major advantages and disadvantages of mechas, and explained them in detail.

If these students want to achieve success in the mecha industry in the future, they must understand these things.

After answering the questions from several students, more than an hour has passed since the open class. Then, Lin Feng entered the next stage.

"Thanks to the three students for their questions, so let's talk about the advantages and disadvantages of mecha first. Next, I will focus on the prospects of mecha."

"What are the prospects of mechas? What is the future of mechas? If you want to understand the future of mechas, you must have a certain understanding of the performance of future mechas."

"How performance directly determines the prospect."

"Performance not only includes the size and combat power of the mecha, but also includes the various functions of the mecha."

"Some people think that the bigger the mecha, the stronger it will definitely be. Although this view is contrary to the actual situation, I personally uphold this view."

"However, with the current scientific level, it is difficult to build a mecha above 150 meters. There are many reasons, so I will list a few briefly."

"First point, the driver's nerve strength requirements are required. If a 150-meter-high mecha is built, it is estimated that the nerve strength values ​​of the two drivers must reach about 700 before driving. At present, the nerve strength values ​​of the top drivers are only 500, and there is a large numerical empty section in between. Therefore, the driver's level limits the height of the mecha.

Perhaps in the future, the driver's nerve strength can be improved through other methods such as drugs, but at present, this is not possible at all."

"The second point is the mode of transportation of mechas. The height of mechas exceeds 150 meters and the weight usually exceeds 10,000 tons. It is very difficult to transport mechas of this weight.

In the past few years, the Pacific Rim Defense Organization's mecha had tens of thousands of tons, but it turned out that the transportation speed was extremely slow through freighter and train sheath, and after transportation was in place, it had to be reassembled, making it difficult to fight against monsters as soon as possible.

Some people think that it can be lifted with a transport aircraft. The largest transport aircraft at present is the Y-20 transport aircraft, which can lift cargo with a weight of 1,500 tons. A 10,000 tons mecha requires eight transport aircraft to lift.

However, the plane was lifted, and the weather was greatly affected. Monsters invaded, but were not affected by the weather."

Third, this kind of 10,000 tons of mecha causes great damage to buildings, such as the damage to the road surface.

For example, if a mecha of 10,000 tons is the pressure on the road surface when walking, the pressure on the road surface is 100 million N, while the limit pressure on the road surface can withstand only 1 million N, which is equivalent to the gravity of the mecha, which has exceeded the pressure limit of the road surface by 100 times.

When using this mecha to fight monsters in the city, there is no need for monsters to attack. The mecha has begun to destroy the city when it walks.

"So!" Lin Feng said three reasons in one breath before he raised his own point of view.
