The content of the sketch Xu Yun saw was very simple, but the information it revealed was also obvious:
Student Xiao Niu has become curious about gravity.
In terms of nature, this is undoubtedly a landmark painting.
But for Xu Yun, who was acting as Apple, the feeling in his heart was a little subtle.
Of course.
Although Newton had some vague premonitions at this time, he was still a long way from completely deriving the law of universal gravitation.
Readers who are not mad at the physics teacher should know this concept:
There is a difference between gravity and universal gravitation.
Gravity is the force that objects experience due to the attraction of the earth, while universal gravitation refers to the tendency of objects to accelerate closer together.
And the direction of gravity is always vertically downward, not necessarily pointing to the center of the earth - it only points to the center of the earth at the equator and poles, but the direction of gravity is pointing to the center of the earth.
As far as the ground is concerned.
The gravity exerted on an object is one component of the gravitational force between the object and the earth. The other component of the gravitational force is used to provide the centripetal force required for the object to rotate with the earth.
Therefore, the acceleration due to gravity is maximum at the poles and minimum at the equator.
Because of this, the derivation process of universal gravitation requires the use of three concepts:
The first is Kepler's three laws, the second is the flow theory derived by Maverick himself, and the third is Hooke's elliptical orbit.
That's right.
The person who first judged the hypothetical experiment of the earth's gravitational object was not Mavericks, but Hook, who later fell in love with and killed Lao Niu.
This hypothetical experiment is actually very simple:
If an object is thrown flatly from a high tower, assuming the earth can penetrate it without resistance, what should be the final trajectory of the object?
Student Xiao Niu proposed that the trajectory of an object should be a spiral and will eventually stay at the center of the earth.
Lord Hooker believed that a flat parabolic object should circle the earth in an elliptical orbit without losing any energy and return to its original place.
Of course.
Hooke intuitively stated the elliptical orbit, but he did not derive it - he only derived the inverse square law together with Huygens. The basis of this thing is to treat the planetary orbit from an ellipse to a circle.
So for those students who failed in this aspect in high school, stop scolding Lao Niu and go scold Hu Ke instead.
But Mr. Niu is such a stubborn person. When faced with Hook's opinion, he accepted it in his heart, but did not show it.
Then I secretly calculated it myself.
At that time, classmate Mavericks had already deduced the art of fluidity, so with the last piece of the puzzle put together, gravity was just like this, or in other words, it was finally deduced by him.
Therefore, the derivation process of universal gravitation is not as simple as smashing an apple and producing results. Unless Xu Yun lists a lot of derivation processes such as ?=dA/dt, otherwise it will simply imply "Why do I fall down?"
Such words make no sense.
And if you want to let the arrogant Mavericks watch your deduction in peace, it is absolutely impossible without some friendship:
Just five months before Mavericks returned home, a girl from Trinity College wanted to ask Mavericks a question. Because she wasted some extra time, Mavericks splashed ink on the girl's face.
This matter was recorded in the files of Trinity College. By the way, there are more than a dozen similar files about Xiao Niu, who can be said to be incorrigible despite repeated admonitions.
So again, Mr. Niu’s academic status is like Mount Everest, but his character is like the Mariana Trench...
The task Xu Yun received was to become friends with Mavericks. In terms of difficulty, it was actually not much lower than deriving the law of universal gravitation.
Moreover, based on the urine properties of that aperture, Xu Yun doubted whether he could successfully write out the entire derivation process without loss - things like traveling through time and space have already appeared, and the Great Speech Spell is nothing at all.
So again, everything must be considered in the long term.
Then Xu Yun's eyes moved away from the manuscript and fell on a metal pedestal.
The main body of the metal pedestal is a cross, about thirty centimeters high. The base is suspected to be made of copper, with a number engraved on it:
1642.12.25.
12.25, which is Christmas.
The moment Xu Yun saw this number, a flash of light flashed in his mind, but he still asked knowingly:
"Mr. Isaac, please tell me this..."
Mavericks reached out and touched the top of the cross and said calmly:
"As you can see, it's my birthday."
Maverick's answer was a bit casual, just like a local introducing to a guest, "That's the flower I planted last year." He didn't expect the other party to give any feedback.
But to his surprise, Xu Yun had a hint of surprise on his face:
“December 25th? Isn’t that Christmas?
It turns out that Mr. Exar and Jesus have the same birthday?”
Then he pointed to the "Holy Bible" on the desk that knocked him unconscious, and said with a smile:
"Mr. Isaac, in my faraway eastern homeland, people like you are generally regarded as lucky ones who have been blessed.
Maybe in a few years, you will be like that person and be worshiped by others in a certain field."
Hearing Xu Yun's words, Mavericks was stunned for a moment, then a hint of excitement appeared on his face, and his tone was slightly trembling:
"Lucky man? Fatty fish, are you telling the truth?"
Xu Yun nodded with certainty and explained:
"Of course it's true. Sometimes such lucky people are nicknamed 'This Son'
They may have had a bad life when they were young, such as being divorced, bullied, betrayed, or even rejected by their parents.
But as long as the right time comes, they will soar into the sky, eventually shining like stars and being as terrifying as the stars!"
Upon hearing these words, Newton's eyes suddenly lit up:
At first, he thought that Xu Yun might be flattering him, but when he finished what he said later, he was sure that what Xu Yun said was true!
Because except for breaking off the engagement, everything else happened in Maverick’s childhood!
And he could be sure that he had no interaction with Xu Yun in the past, and the other party had no ability or need to inquire about his past - he was just an ordinary college student with a bad temper and no popularity. Who would inquire about him?
Therefore there is only one possibility:
I am exactly what Xu Yun said!
Of course.
Newton made this judgment not because he was possessed by a halo of wisdom, but because it involved a secret that he never disclosed and was only mentioned in a letter sent to Formissa in 1719:
He was a senior high school sophomore, and until his death he believed that he was a chosen one who had been given a sacred mission.
And the bud of all this begins with Maverick's birthday - two birthdays assigned to different nodes in later calendars.
...
Note:
Today I asked a friend to inquire about it, and unexpectedly learned that the scanned version of Newton's manuscripts can be found on the Internet at the Bodleian Library of Oxford University. There are more than 170 letters in total, so I downloaded them all first.
When you read this chapter, I was still downloading. It was extremely slow to bypass the firewall, 23kb per second....
Finally, I discovered something so outrageous that even I have been misled for more than ten years, Zhuo!
