Chapter 242 Zeno's Turtle
Soon Isaac and Ye Zhen started making many rodent-killing tools that night.
Compared to the original method of rodent control.
The tools created by Ye Zhen can be said to be beyond the times.
Because Ye Zhen had obtained [Mechanical Heart] before, this made Ye Zhen very handy when making anything related to machinery.
Because this machinery is not limited to those steel products, lathes and the like.
To put it bluntly, machinery is a tool device that can help people reduce the difficulty of work or save labor.
Items such as chopsticks, brooms, and tweezers can be called machines. They are simple machines.
Only because Ye Zhen has the [Mechanical Heart] can he have such hands-on ability.
But Isaac is not inferior to Ye Zhen in any way.
And he handles some details better than Ye Zhen.
Soon a vigorous rat cleanup was underway.
The rats on the farm were wiped out, and nothing escaped.
Ye Zhen had dinner with Isaac and his brother that day.
But in 17th-century England, you couldn’t even think of finding anything delicious.
Because even Great Britain developed into an empire on which the sun never sets.
It’s still a food desert.
What is their national dish?Fish and chips.
That’s right, fish and chips.
That’s it for the national dish, but it’s still a modern national dish.
It's not something from this era.
You want to eat it but you don’t have it yet.
English cuisine is generally considered unpalatable and dark.
For example, look up to the stars.
A simple bread made with cheese and some wheat.
Some vegetable soup and a variety of salads made from freshly pulled vegetables from the ground.
There is also the barbecue on the table, which is simply meat grilled over fire.
Ye Zhen could feel the wild and primitive taste of the meat from a distance.
To put it bluntly, it's fishy.
Before starting to eat, Isaac joined his family with his hands clasped together and his eyes closed.
He was praying with words in his mouth.
"Amen."
Ye Zhen also pretended to pray.
The last dinner ended with Ye Zhen being three cents full.
Because this food really doesn't match Ye Zhen's taste.
After dinner, Ye Zhen found that the system did not mean to summon him.
"Why did you come to me this time?" Ye Zhen didn't understand.
He thought he was playing the role of a man dealing with the plague here.
That's why Ye Zhen came up with the idea of cleaning up the rats.
Let’s nip these plagues in the cradle right from the source.
But after Ye Zhen finished doing this, there was no feeling of summons coming from the system.
Ye Zhen probably did something wrong.
Just like when I met Dayu before, my task was to teach Dayu how to deal with floods.
Ye Zhen also figured out a trace of the rules of the spiritual realm.
"Isn't it dealing with the plague?" Ye Zhen thought about what this spiritual realm wanted him to do.
Ye Zhen sat on the bed and thought.
At this time Isaac came in from the door and lay on another bed.
"Wiggins, it feels like we are still in school." Isaac is still very excited.
Because it's exactly what Isaac's brother said.
Isaac is usually a relatively withdrawn and quiet person.
Even when he went to college, he only had Wiggins as his best friend.
Isaac turned to look at Ye Zhen.
"Wiggins, what method can you use to describe the movement of this particle?"
"Some of the current theories and mathematical tools cannot achieve the results I want."
"Even some professors at the school can't do anything."
When Ye Zhen heard this, he said, "So are you studying this issue recently?"
Isaac and Ye Zhen said carefully: "I think the movement of this particle, or the movement of an object, we can regard the object as an ideal object with no volume but only mass. How do we determine the instantaneous velocity and acceleration? ?”
Ye Zhen pondered for a moment, and he seemed to know what was going on in this spiritual realm.
"Zeno's turtle, do you know?" Ye Zhen said softly.
At this time, Isaac was surprised, "Zeno's turtle? What is this? Why haven't I heard of it?"
Ye Zhen explained: "A thought experiment proposed by the ancient Greek philosopher Zeno."
"Also known as the Achilles Paradox."
Who is Achilles? This is a demigod from ancient Greece.
Some people also translate it as Achilles.
This is about the Trojan War.
But all you need to know is that Achilles runs very fast.
And this Zeno's tortoise is one of the four great beasts in the physical world and is equal to the omniscient and omnipotent demon Laplace.
One is omniscient and omnipotent, and the other is infinite domain cutting.
Ye Zhen and Isaac tell the story of the tortoise race.
It's like putting a child to sleep.
"Suppose now we hold a foot race."
"Among the contestants are the tortoise and Achilles."
"A total of 1000 yards."
When Isaac heard this, he laughed on the bed, "Who thought of this? Achilles is a demigod who can run very fast.
How could this turtle win? Isn't this competition funny? "
This was the first time Isaac heard this story.
Ye Zhen nodded and said: "Normally, if a tortoise competes with Achilles, then Achilles will definitely win because he can run faster than the tortoise."
"We all know this."
"What if we let the turtle go first?"
"Run 100 yards first."
Isaac shook his head and said: "Even if the turtle is allowed to run a hundred yards first, it is impossible for the turtle to win the race."
At this time, Ye Zhen explained: "But if you let this turtle start first, and give the turtle a position advantage to start running first."
"So even if Achilles was much faster than the tortoise, he would never be able to catch up with the tortoise." Isaac exclaimed, "How is that possible?"
"What if time is infinite, infinitely divisible?"
"If time could be divided indefinitely, then there would always be a small gap in time between Achilles and the tortoise."
"Therefore, Zeno believed that Achilles could never catch up with the turtle within the limited time." Ye Zhen said in a calm voice.
But it was like a bolt from the blue in Isaac's mind.
"Infinitely divisible? Infinitely cut?" A storm arose in Isaac's mind.
He froze.
It's like seeing Achilles and a tortoise racing.
There are 100 yards between the tortoise and Achilles.
But Achilles could never chase the turtle in front of him.
Because the turtle is also moving at the same time, in infinitely divisible time.
Achilles can only get infinitely closer to the tortoise.
100 yards, 50 yards, 25 yards, yards...it goes on indefinitely.
Achilles can never catch up with the tortoise.
This is Zeno's tortoise,
Isaac seemed to have an epiphany, and he froze there.
After a long time, Isaac finally recovered.
"Wiggins, you are a genius." The thing that has troubled Isaac for so long finally has a solution! "But there's still something missing."
Ye Zhen continued: “Introduce the concept of infinitesimal, treat the amount of change as an infinitesimal quantity, and calculate the limit of the amount of change.
By studying the slope of the curve, the concept of derivative is introduced, which can be used to describe the slope of the curve at a certain point.
When the change is small enough, the differential is close enough to the true value. "
After hearing Ye Zhen's words, Isaac seemed to be enlightened.
In fact, as long as you give him some time, he can slowly figure it out on his own.
But now Ye Zhen gave him the answer directly.
"That's right! That's right! That's it!" Isaac jumped up from the bed excitedly. "This is the mathematical tool I want."
Isaac came directly over and grabbed Ye Zhen's arm tightly, "This is all your fault, Wiggins!"
"What is this method called?" Isaac thought.
"Why don't we call it calculus." Ye Zhen said with a smile.
"Calculus? That's a good name." Isaac immediately lit the oil lamp.
Write on the paper with a quill pen.
Inspiration came to Isaac like a spring.
Calculus was initially constructed by Isaac in one night.
At this point, how could Ye Zhen not know who the young man sitting in front of the oil lamp table was? He is the inventor of calculus and the greatest physicist in human history.
The last alchemist in history.
Isaac Newton!
Early the next morning, Isaac didn't wake up for a long time and slept until noon.
Because Isaac stayed up all night last night and initially constructed the calculus.
Ye Zhen shook Isaac who was sleeping soundly on the bed.
"Wake up, the sun is already shining on your butt." Ye Zhen shook Isaac.
"Let me sleep a little longer, Wiggins," Isaac murmured.
But Ye Zhen still pulled Isaac up.
Ye Zhen took Isaac to a dark room.
This is the time of day when the sun is at its strongest.
"Wiggins, what are you going to do?" Isaac yawned, obviously not waking up.
"I haven't perfected my calculus yet," Isaac said dissatisfied.
Even after an all-nighter, Isaac was still in a state of excitement.
Ye Zhen holds a prism in his hand.
"You'll know just by looking at it." Ye Zhen directly pulled Isaac to sit in the room.
Isaac didn't understand, "Wiggins, can you let me go back and finish the calculus paper?"
“Inspiration is coming to me now.”
"And I have to go to church in the afternoon." Isaac obviously had a lot to do.
Ye Zhen just stood in a sunny place outside the window.
The midday sun shines through the leaves and shines on Ye Zhen like broken gold.
Ye Zhen is holding the Mitsubishi mirror found from Isaac's house yesterday.
The mainstream theory at that time believed that light was a single color.
But when Ye Zhen shined the refracted sunlight into the house at a clever angle.
Isaac was dumbfounded because he saw rainbow-like colors shining on the white walls of the house.
"My God! Are you a magician! Wiggins!" Isaac watched Ye Zhen transform the sunlight into rainbow-like colors.
Many different colors can be clearly seen on white walls.
Isaac immediately thought that the sunlight was not a single pure color.
It is a mixture of many different colors.
Finally it appears white.
Isaac was once again shocked by Ye Zhen.
"How on earth did you do that!" Isaac suddenly stopped feeling sleepy and walked directly to Ye Zhen.
Approaching the window, Newton directly picked up the prism and started playing with it.
"Is this the nature of light?"
Isaac believed that the nature of light was particles.
But now mainstream science believes that light is a wave.
Because of this issue, the scientific community has been arguing for more than 200 years.
In these 200 years, the particle theory of light and the wave theory of light have been developed.
The two versions have been in heated dispute.
It depends on which statement the mainstream scientists at the time support.
Just like when Isaac became famous because he was a staunch supporter of the particle theory of light.
Therefore, the statement that light is a particle became the mainstream statement in the scientific community and became very popular.
It was not until after his death that the wave theory of light became mainstream again.
Many years later, it was solved by a man named Einstein.
He proposed a theory of wave-particle duality of light.
Light is both a particle and a wave.
This directly ended more than 200 years of scientific disputes.
