Vol 4 Chapter 163: Gravitational constant

Back home, Sulu was still asleep, and Warren closed the door and quickly put in the design of the new torsion scale.
"The reflection of light can achieve secondary amplification, that is to say..."
Valen used magical power to create a slender metal suspension wire, and fixed one end of it to the metal plate, and the other end fixed a flat mirror.
Under the plane reflector is an inverted T-shaped frame. Wallen uses wooden materials. He also prepared two copper of equal weight to be fixed at both ends of the inverted T-shaped frame. So far, the basic structure of the torsion scale is completed.
Obviously it is a very simple instrument, but when it was completed, Varen seemed to see the scorching brilliance. He kicked Sulu, who was still sleeping, excitedly said: "Hurry up, it's time to witness history!"
Su Lu suddenly woke up from his dream, rubbing his distressed eyes and said, "Damn, I had a nightmare. I became an apprentice in a magic school, and the old man Bayern is a calculus teacher, and the Calculus must It takes 90 points to graduate!"
Warren seemed to be a little impatient. He said hurriedly: "Don't worry about calculus, we are about to discover the gravitational constant. Be sober, and help quickly."
Sulu was shocked, Gulu rolled off his chair, and followed Warren to a closed room in shock.
Under the command of Varen, Sulu fixed the metal plate of the torsion balance to the ceiling, and Varen prepared a long metal scale and placed it far away.
Warren took a deep breath and said to Sulu who was confused: "Our experimental design is very simple, but the effect will be very outstanding! Now, you use bright light to aim the mirror."
Su Lu nodded ignorantly, a beam of light burst out from his fingertips, centered on the reflector, which reflected the beam to the metal scale ruler farther away.
Warren frowned and said solemnly: "It's too thick, make it thinner, as thin as you can!"
Sulu looked at the solemn Varun, and didn't dare to care. He concentrated his mind and minimized the beam of light, hitting the straight beam.
Warren raised a high-powered telescope and observed the scale of the graduated ruler, then put down the telescope and recorded a series of numbers with a blank magic scroll.
Then Warren looked tense and hung two large copper of the same weight at the same distance from the two small copper at the same time. Sulu was stiff, controlling the thin beam of light to stay motionless.
The suspension wire is twisted at a certain angle, and the flat mirror rotates accordingly. Although the angle is small, the beam is greatly deflected.
The inverted T-shaped frame stood still, and Wallen raised the high-powered telescope to observe the new value and record it accurately.
He put down his binoculars at will, and ignored Sulu, who was stiff and dare not move. The magic scroll naturally stretched and suspended in the air, and Warren took a quill and wrote seriously on the paper:
"Walen-Sulu Torsion Scale Experiment
Experiment goal: Measure and calculate the gravity constant (symbol)
Gravity often exhibits a weak force. What we need to measure is a pure weak force. Specifically, with the help of Sulu, I designed a simple device called a torsion balance.
The torsion scale is composed of a metal suspension wire, a flat reflector, an inverted T-shaped frame, and two copper of equal weight.
The experiment process is as follows...
The key to this experiment is to amplify the weak force. Sulu and I used two ingenious designs to amplify the weak force.
On the one hand, a small force can generate a larger moment through a longer force arm, which can cause the suspension wire to twist at a certain angle; on the other hand, a flat mirror is fixed on the suspension wire, which can reflect the incident light to a distance from the flat mirror. On the scale, the movement of the light spot from the reflected light to the scale can reveal the slight twist of the hanging wire.
After knowing the weight of the two big copper and the distance between the big copper and the two small copper balls... With the aid of the Ace formula (the formula of universal gravitation), we can easily get the constant = . "
With the help of the universal gravitation formula and the exquisite torsion balance experiment, Wallen easily calculated the gravitational constant. This is an extremely small number. As soon as this number appears, there will be roaring bursts of thunder.
The stiff Sulu also looked at Valen subconsciously, as if a sacred light emerged from Valen, he seemed to hear the world cheering and the stars sighing.
Sita, Ace discovered the anomaly for the first time. With such a lively atmosphere and closely related to him, there must be a wizard who made amazing discoveries through "Magic Mechanics", which drew feedback from Dayuan.
In the temple, the statue of Thoth flickered, and his clone appeared here instantly, murmured: "Wizards and magic are really magical. In my life, I have never seen great source of joy a few times. I did not expect that there is only one I saw it several times in the month.
Can I learn from this path? "
His gaze is a bit blurred and he has some expectations. Even if he is a demigod, he still has it. Thoth has always dreamed of becoming a deity with unlimited potential and a vast territory. He was a demigod at birth, but still half-god after ten thousand years. God, just because he doesn't want to achieve the realm at will.
"The dream realm that Ace fancy is also ordinary in my eyes. Although he is loved by the world, his vision is still too narrow. The stupid dragon is even more so. What an extraordinary food is simply a shame!
I shall achieve a higher field. What is more concise and charming in this world than mathematics. If I can achieve the of mathematics, I will be the king of the world! "
Usually gentle and gentle, Toth speaks his heart here. The reason why he is willing to shelter wizards is because these people use mathematics as a tool, and Toth's ambition rests on mathematics.
Dayuan’s feedback has aroused many people’s reactions~EbookFREE.me~ Ace has flown near Villa Valen, and formal wizards such as Bayern and Dana have also arrived.
Dana was also studying "Calculus" and "Magic Mechanics" during this period. As a faithful believer of Ace's thought, Dana's acceptance of "Magic Mechanics" was very high, and she reconstructed herself in a very short time. Meditation environment and fate star, and follow Ace’s suggestion to use a godless star as fate star.
Her strength has also reached the first level peak state, Ace looked around at will, a little awkwardly avoiding Dana's burning eyes, and nodded in satisfaction.
"Your strength has been greatly improved. Maybe in three to five years, a large number of second-level wizards will emerge. Let's wait here together. It must be an amazing discovery."
Everyone nodded and stared at the villa with hopeful eyes, feeling the feedback from Dayuan, and their mood was agitated.
In the sealed room of the villa, Warren is still writing seriously. The gravitational constant is one of his conclusions. He also wants to calculate the mass of the largest celestial body inside the world, the center of the earth!
The aura of Dayuan is getting stronger and stronger. Although it is far unable to compare with the three laws of Ace and the law of universal gravitation, this kind of strong feedback is almost equivalent to the phlogiston theory.
