Scholar’s Starry Sea

After introducing Mozi’s other research in detail, Professor Pan teased the sparse bangs on his forehead and said with emotion: “It’s a pity, it’s a pity that Saint in the Warring States Period really There are too many. Some Saints feel that they can reach the peak of this life just by thinking, and they know how this world works."

"Until Mencius criticized Mozi later, slowly Our culture in China began to move towards Confucianism and was linked with philosophy, so science has not been well developed in our country."

"But at this point, I suddenly want to mention something, the Internet is actually Many people say that there are no philosophers in our country? I’m really..." Professor Pan showed an expression that didn’t know whether to cry or laugh. "A Brief History" is recommended to him, and it is considered to have contributed to elementary education."

"hahahahaha..."

Wu Bin couldn't help but laugh. He didn't expect this rather rigid-looking professor to be sharp in black.

"But we are not discussing philosophy today, so I won’t say more. I just said that, just to explain why we are called Mozi Sand Dragon, and tell everyone that China is in ancient times. There were already great scientists at that time, so you must not feel inferior to people."

"bang bang bang bang pa pa pa."

Wu Bin applauded. With a bit of emotion, he found that these big cows in scientific research always emphasize not to think that we are inferior to the Western concept when doing science. In addition to patriotic factors, Wu Bin feels that perhaps sufficient self-confidence is also an important quality of creation and invention.

"In the past two years, there has been a time that is long enough to be recorded in the history of science, that is, the Laser Interferometric Observatory announced that humans have detected gravitational waves for the first time. What is a gravitational wave, and how it was discovered What about?"

"This has to be traced back more than a billion years ago, and beyond Earth several millions of outer galaxies, two black holes collided. The gravitational waves produced by this collision, Just like ripples, moved towards all around spread. And at that time on our Earth, dinosaurs were experiencing the process of rise, evolution, and extinction."

"At this time, the ripples of gravitational waves are still the same. It’s still moving forward. About 50,000 years ago, gravitational waves reached our galaxy, and this was when our ancestor Homo sapiens began to replace Neanderthals and became the most important apes on Earth."

I heard that Gu Jiaqi here subconsciously wanted to ask Wu Bin what is a Homo sapiens and what is a Neanderthal, but thinking of Wu Bin's instructions just now, I forcibly swallowed the question back to her lips.

"100 years ago, 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 Renavis produced a huge detector nearly four kilometers in length, and finally detected this stock that had been in the universe more than a billion years ago. Progressive gravitational waves."

"The reason why I want to quote this thing today is to be a little stronger. When we become humans, there will be an eternal topic, which is exploration, and today I The subject of the report is..." Professor Pan pointed to the big screen with five characters displayed on it.

[Motivation to explore]

"ka-cha", "ka-cha", "ka-cha"

For a while, it was another shot of a camera The sound rang.

After Professor Pan used a very interesting event to introduce the topic he was going to talk about today, he introduced the religion that initially brought mankind a sense of spiritual security, promoted the religion of equality for all, and went to Copernicus’s heliocentric theory. And observations after Galileo invented the telescope.

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

Because before this, Christianity has always told 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 lifted his glasses and said: "First of all, I emphasize, I am not religious, but what I want to say next is true. It makes me feel very magical."

"That is after Galileo's death in 1642, Newton was born in 1643."

After introducing the deeds of this genius, Professor Pan The conclusion is.

"Why Newton’s position in the scientific community is so important because he told humans why the apple fell to the ground and why the planet revolves around the sun. These are actually calculable."

"In this way, it has brought about the greatest liberation of thought in human history. From then on, mankind has learned that the world exists independently of mankind, and mankind can stare at this world, think deeply, and can be a part of the world. To understand and research."

Although Wu Bin knows all this knowledge, he is still taking notes, because this kind of lecture that connects the entire human history with the history of science makes him very interesting. Sometimes It takes a certain level to organize a lot of events into a clear main line.

Professor Pan then introduced Faraday’s discovery of electromagnetic induction, and understood that electricity can be transformed into magnetism, and magnetism can be transformed into electricity through motion. Now we can generate electricity because of this.

Then Maxwell used another Simultaneous 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 killed 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 very simple.

For example, when you were too hungry, a bowl of rice suddenly fell from the sky, and you gobbled it up.

Then when the meal was ordered on the 2nd day, another bowl of rice fell from the sky.

After eating so comfortably for a week, but you are starting to worry, why does the sky fall? What if it doesn’t fall tomorrow? Am I going hungry again?

So the 2nd day with this idea, you eat half of the meal, and use the remaining half for research. If you want to be able to cook your own meal later, you don’t have to worry about starving again. NS.

The example is very simple, but the truth is very profound. Everything in the world, no matter what you want to understand, you have to learn from its source, which is the most basic part, or else learn No matter how many of them, they just learned a type and a skin.

Is it able to fly by making an airplane shell like an airplane? Of course not.

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