Xueba's Sea of ​​Stars

Chapter 272 Motivation for Exploration (Part [-])
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."

"Until Mencius criticized Mozi later, the culture of our Hua country gradually began to move towards Confucianism, which was connected with philosophy, so science did not develop very 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 laughing out loud, he didn't expect that this rather rigid-looking professor would be sharp in black.

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

"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 not to think that we are inferior to the concept of the West when they do science popularization. In addition to patriotic factors, Wu Bin feels that perhaps sufficient self-confidence is also an invention. important quality.

"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 goes back more than a billion years, when two black holes collided millions of galaxies away from our earth, and the gravitational waves generated by this collision spread like ripples in all directions. At that time on our earth, dinosaurs were going through the process of rising, evolving and extinction."

"At this time, the ripples of gravitational waves are still advancing. About 5 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 most When the main orangutan."

Hearing this, Gu Jiaqi subconsciously wanted to ask Wu Bin what is Homo sapiens and what is Neanderthal, but thinking of Wu Bin's exhortation just now, she still swallowed the question that came to her lips.

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

"It was not until 20 years ago that the team of the Nobel Prize winner Professor Renavis created a huge detector nearly four kilometers in length, and finally detected this gravitational force that has been advancing in the universe more than billions of years ago. Wave."

"The reason why I want to quote this matter today is to make it stronger. When we become human beings, there is 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.

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

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

Human beings discovered for the first time 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.

Then Kepler 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, I want to emphasize that I don't believe in religion, but what I'm going to say next really made me feel very amazing."

"That's when Galileo died in 1642, and Newton was born in 1643."

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

"The reason why Newton's status in the scientific world is so important is because he told mankind why apples fall to the ground and why planets revolve around the sun. These are actually calculable."

"In this way, the greatest liberation of thought in human history has been brought about. From then on, human beings understand that the world exists independently of human beings. Human beings can gaze at this world, think deeply, and understand and understand a part of the world. Research."

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 very interesting. Sometimes it is necessary to organize a large number of events into a clear main line. 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 the seemingly independent phenomena of light, electricity, and magnetism.

Finally, it leads to Planck's quantum theory and Einstein's theory of relativity, which are theories that have been in love and killed each other for a hundred 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 also very simple.

For example, when you are so hungry that a bowl of rice suddenly falls from the sky, you gobble it up.

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

You ate comfortably for a week, but you started to worry, why did the food fall from the sky?What if it doesn't drop tomorrow?Am I going to starve again?
So on the second day when you had this idea, you ate half of the meal and used the remaining half for research, hoping that you could cook your own meals in the future, so you don’t have to worry about starving again.

The examples are superficial, but the truth expressed is very profound. Of all things in the world, no matter what you want to understand, you have to learn from its source, which is the most basic part. Otherwise, no matter how much you learn, you will just learn Get a shape, learn a skin.

Is it possible to fly by building an airplane shell according to the shape of an airplane?Of course not.

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