After a detailed introduction to Mozi's other researches, Professor Pan stroked the sparse bangs on his forehead and sighed: "It's a pity, it's a great pity that there were too many saints in the Warring States Period, and some saints think that just by thinking, they can reach the pinnacle of their lives and know how the world works." ”

"It wasn't until Mencius criticized Mozi that our Chinese culture began to move towards Confucianism and was associated with philosophy, so science was not well developed in China."

"But speaking of which, I suddenly want to mention that there are many people on the Internet who say that there are no philosophers in my country? I'm really ......," Professor Pan showed a laughing expression, "If you hear someone say that next time, you can recommend the book "A Brief History of Chinese Philosophy" to him, and it can be regarded as a contribution to primary education." ”

"Hahaha......"

Wu Bin couldn't help laughing, he didn't expect this old professor who looked quite rigid to be sharp.

"But we don't talk about philosophy today, so I won't say more, I just said that, just to explain why we call Mozi Salon, because we want to express that in fact, we have great scientists in China since ancient times, so you must not feel inferior to others."

"Bang bang."

Wu Bin applauded, while a little emotional, he found that these scientific research bulls in the science popularization will emphasize not to think that we are inferior to the concept of the West, in addition to the patriotic factor, Wu Bin feels that maybe sufficient self-confidence is also an important quality of creating inventions.

"In the past two years, there has been a time that can go down in the history of science, that is, the laser interferometer observatory announced that human beings have detected gravitational waves for the first time, and what are gravitational waves, and how were they discovered?"

"More than a billion years ago, two black holes collided millions of miles away from our Earth, and the gravitational waves from this collision propagated like ripples. At this time, on our earth, dinosaurs are going through the process of rising, evolving and dying out. ”

"The ripples of gravitational waves are still advancing, about 50,000 years ago, gravitational waves reached our galaxy, and this is the time when our ancestor Homo sapiens began to replace Neanderthals as the most important apes on Earth."

Hearing this, Gu Jiaqi subconsciously wanted to ask Wu Bin what Homo sapiens and Neanderthals were, but thinking of Wu Bin's advice just now, he still swallowed back the question that came to his mouth.

"100 years ago, Albert Einstein, known as the most powerful brain, predicted the existence of gravitational waves and inspired decades of speculation and fruitless search."

"It wasn't until 20 years ago that the team of Nobel laureate Professor Reinavis built a huge detector of nearly four kilometers or so that it finally detected this gravitational wave that has been moving in the universe for more than a billion years."

"The reason why I want to quote this matter today is to be stronger, when we become human beings, there will be an eternal topic, that is, exploration, and the topic I want to report today is ......" Professor Pan pointed to the big screen, which showed five big characters.

【Motivation for Exploration】

For a while, there was another sound of cameras taking pictures.

After Professor Pan introduced the topic of his lecture today with an interesting incident, he introduced the religion that originally brought human beings a sense of spiritual security and promoted equality, to Copernicus's heliocentrism and Galileo's observation after the invention of the telescope.

For the first time, mankind discovered that the earth was not the center of the universe.

Because until then, Christianity has always told everyone that we are the center of the universe.

Subsequently, Kepler summarized the laws of motion of the planets and laid a very important foundation.

After saying this, Professor Pan suddenly raised his glasses and said, "First of all, I want to emphasize, I am not a religious believer, but the next thing I want to talk about does make me feel very amazing. ”

"That is, after the death of Galileo in 1642, and in 1643, Newton was born."

After introducing the deeds of this genius, Professor Pan's concluding remarks were:

"The reason why Newton is so important in the scientific community is that he told mankind why apples fall to the ground and why planets revolve around the sun, these are actually calculable."

"In this way, it has brought about the greatest emancipation of human history and thought, and mankind has learned that the world exists independently of human beings, and that human beings can gaze at the world, think deeply, and understand and study a part of the world."

Although Wu Bin knows all this knowledge, he is still taking notes, because this kind of lecture that connects the entire history of mankind and the history of science makes him find it very interesting, and sometimes it takes a certain level to organize a large number of events into a clear main line.

Then Professor Pan introduced Faraday's discovery of the phenomenon of electromagnetic induction, and understood that electricity can be changed into magnetism, and magnetism can be converted into electricity through motion, and now we can generate electricity, which is the benefit of this.

Then Maxwell used a system of equations to unify all the seemingly independent phenomena of light, electricity, and magnetism.

Finally, Planck's quantum theory and Einstein's theory of relativity are introduced, which are the theories of falling in love and killing each other for a hundred years.

And their purpose is actually the same, they are all to reveal the origin and evolution of the universe.

As for why scientists are so curious about the origin of the universe, the reason is simple.

For example, when you are so hungry that you can't do it, a bowl of rice suddenly falls from the sky, and you gobble it up.

Then when it was time to eat the next day, another bowl of rice fell from the sky.

You just eat comfortably for a week, but you start to worry, why does food fall from the sky? What if it doesn't fall tomorrow? Am I going to starve again?

So the next day with this idea, you eat half of the meal, and the remaining half is used for research, hoping that you can make your own food in the future, so that you don't have to worry about starving again.

The example is very shallow, but the truth expressed is very profound, in all things in the world, no matter what you want to understand, you have to start from its source, that is, the most basic part, otherwise no matter how much you learn, you will only learn a type, learn a skin.

Can you make the shell of an airplane like an airplane and fly? Of course not.

And that's why so many generations of scientists want to understand the origin of the universe.
