"You have learned the most basic counting, and your rough estimates are pretty good."
Lin Ke stood in front of the stone house. Not far in front of him sat cross-legged sixteen newly elected people and the chief Chen.
"Next, I will explain in detail what mathematics is..."
What is mathematics?
One of the cornerstones of science!
In previous lives, those who did not complete nine years of compulsory education always said that metaphysics was so good and mathematics and science so bad...
The results of it?
Learning from those masters of metaphysics who have been developing for thousands of years is not worth a bullet.
The development of science in just a few hundred years has far surpassed the dancing masters that some primitive tribes in paradise have maintained for thousands of years.
The foundation of science is mathematics!
Physical theorems, chemical reactions, biological changes, astronomical deductions, etc., are all subject to change.
But the essence of mathematics remains unchanged!
After specifying the two numbers one and one, the number they add up to is two.
As long as it is within the specified range, one plus one equals two!
Of course, some brain teasers and the like like to be clever and will add some things that are not within the prescribed range.
For example, a man plus a woman equals three people, namely father, mother and child, and may even equal birth.
But those are all things outside the prescribed scope.
Therefore, mathematics is one of the eternal things in science!
You can use mathematics to prove something is correct, and you can use mathematics to prove something is wrong.
Ever since, after knowing the physical mass of the cannonball, the gravity of the planet, the reaction method of chemical substances, the reaction time which is the explosion time, and the parabolic equation.
You can then know where your cannonball will land and explode after it is fired from where there is no external force or very little external interference.
For these things, if you use the methods of dancing with gods, burning tortoise shells, or throwing copper coins into divination, there will be no "gods" or other mysterious beings who can tell you the answers.
And the calculation of these things requires tools like mathematics!
Therefore, mathematics is the cornerstone of science!
"...So, four people can stand per square meter here. I can roughly calculate that there are about 30,000 people here below the surface. Adding in some people on the trees and underground, it is estimated that there may be between 40,000 and 60,000.
between."
Lin Ke smiled and gave examples to the primitive people in front of him.
"For example, Chen punched a rock. I only need to know how heavy the rock is, then know the air resistance, how strong his power is, and then know the direction of his punch, and...and..."
"After knowing this, I can accurately predict where the stone will fly."
They didn't understand what Lin Ke said about mass, gravity, etc., not to mention air resistance and the like, which the people below couldn't understand.
The CPU is burning up!
However, they did not feel that it was serious.
But at this time, there was a female tribesman squatting on the ground on all fours, and she lifted her long hair that almost covered half of her face, and asked doubtfully: "My God, do we know what is so powerful about this stone? Whether I know it or not, I can do it.
Crush this stone into pieces."
As she said that, the female tribeswoman punched the stone that Lin Ke pointed at just now and smashed it into pieces.
"Haha, okay, it's good to have doubts! If you have doubts, you can answer them yourself, or you can ask other people, but I hope that in the future you can all answer these questions yourself."
Lin Xiao smiled and did not blame this female tribesman for her rudeness.
Because in the future these sixteen people will manage this plane like Chief "Chen".
People who can achieve something in mathematics and are talented will at least be able to do more than just arithmetic in the future, but management, research, development, etc., and they are likely to do very well.
These are sixteen seeds!
In previous lives, the status of mathematics as the main subject in the college entrance examination has never wavered, because mathematics can exercise the human brain and train people's thinking ability.
Language subjects such as English are different.
Many powerful scientists may have never learned English, but they still won the Nobel Prize in Chemistry or researched something, as was the case in their childhood.
Therefore, English is no longer the main subject in many places.
In Lin Ke's previous life, he had many classmates and friends who were amazingly talented in subjects such as mathematics and physics, but it was because of subjects such as English and Chinese that they fell into the second or even third rate.
Top talents should be studied!
In the past life, some parents thought that their children should understand the ways of the world and understand this and that. Even many people felt this way.
As a result, scientific and technological development is so stretched.
For example, once the Nobel Prize winner in physics was originally the principal of a school in Sichuan, but he did not continue to serve as the principal because he failed the assessment on the eve of winning the prize.
Netizens joked that when Einstein came to Lin Ke's hometown in his previous life, he might have to hand over two cigarettes or two bottles of moss wine before he could take office. Einstein might even take a job there and wait to die.
The tragedy of his previous life is still vivid in his mind, and Lin Ke will naturally not let it happen again.
If you are talented in mathematics, you should study mathematics well!
For these primitive people, apart from their own strength, the most attractive thing is probably his "god".
Of course, what attracts others to him as "my god" is probably because of his strength. In addition to his fighting strength, he also has the strength of wisdom.
Thinking of this, Lin Ke said to the female tribe member who had the courage to ask just now:
"Child, if it is a stone, of course there is no need to calculate these, but have you ever thought about it..."
"When you see an enemy who uses 30% of his force to defeat a stone like this, you can calculate your enemy's 30% force based on the distance, height, and weight of the stone itself, etc.
How big is it, and how big is 100% of the force?"
"If you encounter a tribe, how do you judge the strength of the opponent before there is a fight? Is this method more accurate? This is just a superficial example. You should draw inferences."
"What is an inference? They can hit rocks, can they also hit wood? Can they also hit people? Or move some heavy objects? Or based on the depth of the footprints on the ground after they walk..."
As they spoke, the eyes of these seventeen people became brighter and brighter.
learn by analogy!
Reverse Thinking!
Equation thinking!
All kinds of novel ideas were told by Lin Ke. These primitive people didn't know how much they could remember, but they all felt...
This math is really awesome!
"If one day you understand everything, you can even push a rock as big as a mountain with one finger!"
"You can even lift a stone as big as the entire earth!"
"You need to use your own wisdom as strength to leverage the power of everything in the world! Of course, this requires a fulcrum..."
