Chapter 272 The Motivation for Exploration (First Update)

After introducing Mozi's other research in detail, Professor Pan lifted his sparse bangs on his forehead and said with emotion: "What a pity. It's a great pity that there were so many saints during the Warring States Period. Some saints felt that just through thinking , you can reach this pinnacle of life and know how the world works."

"It wasn't until Mencius later criticized Mozi that our Chinese culture gradually began to move toward Confucianism and became associated with philosophy, so science did not develop well in our country."

"But when I say this, I suddenly want to mention that there are many people on the Internet saying that there are no philosophers in our country? I really..." Professor Pan showed a dumbfounded expression, "If you hear someone say that next time, You recommended the book "A Brief History of Chinese Philosophy" to him, which can be regarded as a contribution to primary school education."

"Hahahahaha..."

Wu Bin couldn't help but laugh out loud. He didn't expect that this professor who looked quite rigid was actually sharp in appearance.

"But we are not discussing philosophy today, so I won't say more. What I just said is to explain why we call it Mozi Salon, and to tell everyone that in fact, our country already had great heroes in ancient times. I am a scientist, so everyone must not feel inferior to others.”

"Pa pa pa pa pa pa pa."

While applauding, Wu Bin felt a little emotional. He found that these big names in the scientific research field would emphasize the concept of not thinking that we are inferior to the West when doing science popularization. In addition to the patriotic factor, Wu Bin felt that perhaps sufficient self-confidence is also responsible for creation. important qualities.

"In the past two years, something happened that is worthy of being recorded in the history of science. That is the Laser Interferometer Observatory announced that humans have detected gravitational waves for the first time. What are gravitational waves and how were they discovered?"

“This dates back to more than a billion years ago, when two black holes collided millions of outer galaxies away from our earth. The gravitational waves generated by this collision spread like ripples in all directions. At that time, on our planet, dinosaurs were experiencing the rise, evolution and demise of the dinosaurs."

"At this time, the ripples of gravitational waves were still advancing. About 50,000 years ago, the gravitational waves reached our Milky Way, and this happened to be when our ancestors, Homo sapiens, began to replace Neanderthals and began to become the oldest living species on earth. When it comes to the main apes.”

After hearing this, Gu Jiaqi subconsciously wanted to ask Wu Bin what is Homo sapiens and what is Neanderthal, but thinking of Wu Bin's instructions just now, she swallowed the question that was on her lips.

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

"It wasn't until 20 years ago that the team of Nobel Prize winner Professor Renavis built a huge detector nearly four kilometers long that they finally detected the gravitational force that had been advancing in the universe more than a billion years ago. Wave."

"The reason why I want to quote this incident today is to make it stronger. After we become human beings, there will be an eternal topic, that is exploration, and the topic I want to report today is..." Pan said The professor pointed to the big screen, which displayed five large characters.

Suddenly, there was another sound of cameras taking pictures.

After Professor Pan used an interesting incident to introduce the topic he was going to talk about today, he introduced the religion that initially brought a sense of spiritual security to human beings and promoted the equality of all people, to Copernicus’ heliocentric theory and Galileo’s observations after he invented the telescope. .

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

Because before this, Christianity has been telling everyone that we are the center of the universe.

Kepler then laid a very important foundation for summarizing the laws of planetary motion.

After saying this, Professor Pan suddenly raised his glasses and said: "First of all, let me emphasize that I am not a religious person, but what I am going to say next really made me feel very magical."

"That was after Galileo died in 1642, and Newton was born in 1643."

After introducing the deeds of this genius, Professor Pan’s concluding remarks were.

"Why Newton is so important in the scientific community is because he told mankind why an apple fell to the ground and why the planets revolve around the sun. These can actually be calculated."

"This has brought about the greatest liberation of thought in human history. Human beings have since understood that the world exists independently of human beings. Human beings can gaze at this world, think deeply, and understand and understand part of the world. Research."

Although Wu Bin knew all this knowledge, he was still taking notes because he found this kind of lecture that connected the entire history of mankind and the history of science very interesting. Sometimes it was necessary to organize a lot of events into a clear main line, which was also A certain level is required.

Then Professor Pan introduced Faraday’s discovery of the phenomenon of electromagnetic induction, and he understood that electricity can be transformed into magnetism, and magnetism can be transformed into electricity through movement. Today we can generate electricity, thanks to 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 were introduced. These two theories have been in love with each other for hundreds of years.

And their purpose is actually the same, both 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 extremely hungry, a bowl of rice suddenly falls from the sky, and you wolf down it.

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

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

So the next day after you came up with this idea, you finished half of the meal and used the remaining half for research. You wanted to be able to cook your own meals in the future, so you didn't have to worry about going hungry again.

The example is very superficial, but the truth expressed is very profound. No matter what you want to understand about everything in the world, you have to start from its source, that is, the most basic part. Otherwise, no matter how much you learn, you will only learn. I gained a style and a new skin.

If the shell of an airplane is made according to the shape of an airplane, can it fly? Of course not.

And this is why so many generations of scientists have wanted to understand the origin of the universe.
