Chapter 54 54. The theory of round earth, advanced wisdom (3.5k monthly votes requested)
【What is the shape of the world?Is the sky round and the square square correct?Does the world have borders?If you reach the edge of the world, will you fall? 】
Zhao Xuanqi decided to answer this question.
With his knowledge, answering this question is relatively easy, has a relatively large impact, and is more appropriate. Other questions are more difficult for him to answer.
As long as this question is answered, it can definitely reshape people's outlook on the world, make great progress in astronomy and geography, and give people a new and different understanding of the world!
Some of the knowledge and theories contained in it are definitely pioneering and advanced for this era, and will have a profound impact on future generations!
It would be best if the rewards he could get could be increased. If he couldn't, it wouldn't matter. It wouldn't have much impact on him anyway.
The additional questions are not scientific examination questions.
No matter how you answer, no matter how outrageous your answer is, it will not have much impact on the results of the Jinshi examination.
"The myths of the Northern Wei Dynasty are not much different from the Chinese myths. They are also about the creation of the world by Pangu, heaven and earth. People's understanding of the world belongs to the round sky and the earth."
"The sky is a circular cover that covers the square earth. In their understanding, the world has boundaries. If you reach this boundary, you will fall and die..."
"In this mythical concept of a round sky and a round place, the height of the sky is limited. When you reach a certain height, you can touch the barrier of the sky. The thickness of the earth is also limited. If you break the deepest part of the earth, you will fall out of the earth. …”
"And the understanding of the starry sky and the universe is also at its most elementary stage..."
"The Northern Wei Kingdom is the center of the world and the center of the universe. All the surrounding countries are born around the Northern Wei Kingdom. The center of the stars, the universe, and all things is the Northern Wei Kingdom. The Kingdom of Heaven is barbaric and wild in all directions..."
A smile appeared on Zhao Xuanqi's face.
Modern education allowed Zhao Xuanqi to understand the ridiculousness of all this and the ridiculousness of this worldview.
The sky is round.
Naturally not true.
The world is not a cover, nor is the ground a square.
The world is round!
The whole world is a round sphere!
Well, this answer is even more outrageous.
However, this outrageous answer is the truth.
This knowledge theory is groundbreaking for this era and can definitely break the three concepts.
Presumably, once other people hear the statement that the world is round, they will laugh from ear to ear and regard this as hysteria.
If they were told that the ball of the world was still spinning at a high speed, they would probably go crazy.
If the world is round and constantly rotating, wouldn’t people living in the world fall out of the world?
The world keeps spinning, why can’t people living on the mainland feel it?Why don't people spin?Why don't people get dizzy?
I'm afraid there will be a hundred thousand reasons why.
"So I want to prove, use some reasons to prove why the world is round, and at the same time prove that the stars in the sky are also round, and turn the geocentric theory of this world into a round earth theory..."
Zhao Xuanqi slowly thought about it in his mind.
Go through the knowledge you usually learn in your mind, and think back to how people on earth proved that the world is round in previous lives.
Since ancient times, ancient civilizations such as China, ancient Egypt, ancient Babylon, and ancient Greece have believed that the earth is flat, and the sky is like a huge, transparent, upside-down pot, covering the entire earth, that is, the sky. Round land is "square".
The junction between heaven and earth, or the end of heaven and earth, is far, far away, and no one has ever been able to reach the end.
Some people believe that there is a thin gap at the junction of heaven and earth, which is insurmountable by humans and only gods can pass through.
Others believe that the end of the earth is an abyss and there is no real horizon. No matter where you go, the horizon is always infinite.
So, what is the shape of the earth underneath?
Some people think that the earth was humped by an extremely huge turtle, and then this turtle was humped by another huge turtle, and the cycle repeated until infinity.
Some people believe that the earth is semi-spherical or rectangular, floating in the air.
The first person to raise questions was the ancient Greek mathematician Pythagoras. As a mathematician, he believed that everything in the world should be composed of numbers, and the initial shapes should be geometric figures. The beauty of nature is the beauty of figures and numbers, and the most harmonious The most perfect geometric figures are circles and balls.
The stars in the universe should be perfectly spherical, and the earth at the center of the universe should be spherical, and cannot be an imperfect semicircle.
In fact, Pythagoras just guessed the answer by chance and did not provide convincing evidence.
At the same time, some people continued to question it, because according to the spherical hypothesis, if you keep walking until you reach the edge, you will fall immediately. This is terrible.
Then comes the philosopher Aristotle.
Aristotle presented several pieces of evidence in his published Treatise on the Heavens.
First, the sails and hull will not disappear on the horizon at the same time, indicating that the earth is uneven.
When sailing on the sea, you will find that when a ship in the distance moves towards the horizon, the hull will first fall below the horizon, followed by the sails.
On the contrary, when a distant ship is approaching you towards the horizon, the sail appears first and then the hull. In short, the sail and the hull will not slowly become smaller and disappear at the same time.
Many people still think that the above experiment proves that the earth is spherical. In fact, at most it can only prove that the earth's surface is curved.
Because if the earth is flat, the scenery will only get smaller and smaller at the same time until it disappears from the human eye's vision.
In response to this evidence, opponents explained: Since the transparency of the sea air changes with altitude, the transparency of the air below is not good, so the eyes cannot see it disappearing at the same time.
The second is that the stars change with the changes in the position of the earth.The different positions of the stars depend on your position on the earth. If you follow the North Star, there will always be stars appearing on the horizon in front of you, and there will always be stars disappearing on the horizon behind you, which means that the earth cannot be flat.
The third is the lunar eclipse phenomenon.
The moon can be seen by us because it reflects sunlight, but during a total lunar eclipse, the direct light from the sun to the moon is blocked by the earth, or the moon walks into the shadow of the earth.
During the entire lunar eclipse, it can be clearly seen that there is an obstruction blocking the moon's reflection and casting a shadow on the moon's surface. This shadow is obviously almost arc-shaped.
This means that the obstruction must be a sphere, and this sphere can only be the earth itself. At the same time, no matter what angle the earth rotates, the shadow cast by the earth on the moon is always round.
So the earth can only be a round sphere.
Although Aristotle gave a sufficient argument, it was still difficult for the ancients to accept it.
It’s not that ancient people had low IQs, the main reason is the above-mentioned question: If the earth is spherical, why don’t people fall while walking?
This question has troubled mankind for more than 2000 years, and it can only be answered until the genius Lord Niu is born.
Therefore, if Zhao Xuanqi wants to prove that the earth is round, he must write down Newton's laws and gravity, and then make up a story for himself about an apple hitting his head.
Fortunately, he had these memories of his previous life vividly in his mind, so Newton's laws could be written down easily.
Zhao Xuanqi wrote down the above methods one by one that can prove the roundness of the earth, listed a lot of rigorous knowledge, and then compiled Newton's law and gravity theory below.
Keep thinking about history.
After Newton, the ancient Greek mathematician, geographer, and astronomer Eratosthenes took the stage.
Eratosthenes discovered that during the summer solstice, the sun would shine directly on the city of Seini (now Aswan) (apparently located exactly on the Tropic of Cancer).
So he came up with a genius experiment:
Observations of the sun were made at the same time as the summer solstice in Alexandria, 5000 Greek miles (800 kilometers) away.
Eratosthenes raised a stake in the ground and watched its shadow.
It was found that the angle between the sunlight and the wooden pile was about 7°.Eratosthenes believed that this was because the earth's surface was curved, causing the sun's rays to hit each place on the earth at different angles, thus indicating that the earth was spherical.
Through estimation, Eratosthenes calculated that the Earth's circumference was approximately 40000 kilometers, with an error margin of within 10%, which was a remarkable achievement.
Erecting a pole, touching the sun at different times refracts the shadow, and finally forms a circle. This proves that the roundness of the world is indeed very reliable.
Finally, in the early 16th century, the Portuguese navigator and explorer Magellan's voyage around the world (actually working for Spain) proved indisputably that the earth is a sphere.
Zhao Xuanqi went through this knowledge in his mind.
Then write down the answer.
Write down all the knowledge and experiments that can prove that the world is round on the answer sheet, densely packed.
Various mathematical laws and some physical laws are also added as supporting evidence.
As long as the people above do some experiments, such as erecting a pole experiment, they can basically confirm that the world is round, and even calculate how wide and wide the world is.
The most important thing is that Zhao Xuanqi wrote down the method of making a telescope. He used a special telescope to look at the stars in the sky at night and roughly concluded that the stars were round. That was enough to prove that the world was round.
Of course, there may be some people who don’t believe it, but that doesn’t matter.
Anyway, I wrote it down. Whether others believe it or not, and whether they conduct experiments or not, that is their business.
The genius is on the left, the madman is on the right.
Your knowledge is 100 years ahead of time and others may be able to understand it.
Three or four hundred years in advance, perhaps only a genius can understand it.
But if it were 1000 or two thousand years in advance, you would only be regarded as a madman.
This wisdom is inherently advanced, and it is normal for people of this era not to understand it. It is also normal for people of this era to be unable to understand advanced geniuses.
"From now on, Newton's law will no longer be Newton's law. The theory of gravity no longer belongs to Newton, but to me. Everything Newton achieved scientific status in his previous life will belong to me..."
"You must know that with these theories, Newton directly became the top physicist in human history and the greatest scholar who influenced human history. As long as humans exist, there will be knowledge about him in textbooks. Now these achievements are all mine. It’s over!”
"Even if the theories I wrote down include laws, gravity, etc., contemporary people don't believe them and even sneer at them."
"But it doesn't matter. As time goes by, the world continues to develop, and eventually science breaks out and physics develops. This knowledge of mine will always have its own vitality in the future."
"Only those in later generations, those thousands of years from now, will understand the value of this knowledge, and will be shocked by the advancement of this knowledge, and will understand my greatness."
"Maybe I can get many titles."
"For example, the greatest physicist in ancient times? The greatest wise man in ancient times? The most powerful astronomer in ancient times? The greatest mathematician? Zhao Xuanqi's law of gravity? The theory of round earth No. 1?"
While muttering to himself, Zhao Xuanqi put the last word into words.
Every handwriting is perfect, without any alteration or error.
At this point, this scientific examination is over for him, and he can just wait for the end of the scientific examination silently.
