Magus Tech (Technological Wizard)

At the end of the second floor, in the room.

This is a very large room with an area of ​​tens of square meters. Every corner is cleaned cleanly. The quilts on the bed are all newly changed. The air is filled with a faint fragrance of flowers, giving people a comfortable feeling. .

Li Cha nodded in satisfaction and sat down on the table. Pandora went straight to the soft bed, her eyes straightened, as if she was possessed, she sat down on the bed with a "bang", without saying a word, she just kept the same look, constantly in a daze.

Pandora has been like this for several days.

And the reason for this is because, after the initial excitement of leaving White Rock City, Pandora thought of her experience in White Rock City, and felt that she was very useless. I can't learn anything well, and I can't even fight. It's really sad.

After some serious thinking, Pandora made a very solemn request to Li Cha, that is, she hoped to learn some really useful things from Li Cha, so as to avoid similar situations in the future, but it would not be useful.

Really useful!

Pandora especially emphasized the tone, emphasizing these four words.

After doing some research, Li Cha found that Pandora was not joking, but really thought about it.

Really useful stuff?

What is really useful stuff?

Are fighting skills useful? It's useful, but you don't need combat skills to do experiments, even if you are a master of combat, it doesn't help you to do experiments, which is why Pandora sometimes frustrates.

Is it useful to do experiments? It is very useful, but if you do experiments to make flowers, the combat power will not be improved in any way. Just letting Pandora do the experiment is actually a waste of Pandora's powerful combat power.

To be honest, many useful things are one-sided and limited, and can only function in one field or several fields. Once they exceed this scope, they are useless.

Even scientific knowledge is like this.

A person is powerful in the biological field, but throwing him into a mechanical factory is also at a loss.

A person who has made outstanding contributions in the field of mechanical manufacturing, even if he switches careers to cultivating cells, he will have no way to start.

What is really useful stuff? What is something learned that can be applied anywhere without any restrictions?

In other words, what is the nature of science? What is at the heart of everything?

There is only one answer, and that is - mathematics.

Well, math.

At the bottom of the whole world, the whole rational, scientific world, there is an unshakable cornerstone, and that is mathematics. On the cornerstone of mathematics, there will be knowledge of physics, chemistry, biology and other subjects.

The whole world, the truth of the whole world, every law and formula, are all constructed based on mathematics.

For example, Newton studied Newton's second law: the magnitude of the acceleration of an object is proportional to the force, inversely proportional to the mass of the object, and proportional to the reciprocal of the mass of the object;

That is, F=m*a.

F=m*a, what a concise and sacred formula, in the field of classical mechanics, nothing can violate it.

But why is this formula the way it is? Why was Newton able to say this formula so accurately? Has he opened up the whole world and peeped into the real world principle?

Obviously not.

In fact, Team Niu did not see any principles of the world. The reason why he had this formula is that he first defined F, m, and a, and then combined them into a formula.

In the same way, if he likes, he can make the formula a little more complicated, such as F=d*t*g, or W=5h*r*k*¥/2472 and so on.

In this case,

Then all the basic concepts of the entire classical mechanics may have to be replaced to explain the letters in the formula. But no matter how the basic concept is changed, in this system, the interior is self-consistent and can be used to explain the phenomenon of movement.

Therefore, it is not Newton who discovered the principle of the world at all, but he put forward a hypothesis, and then just explained the phenomenon of the world.

In the same way, other disciplines are almost the same, constructing the whole system from top to bottom, internally, it is self-consistent, and externally, it can explain the various manifestations of the world operation to the greatest extent.

That's how the whole technology came about.

First a hypothesis, then a verification, and finally a theorem.

Therefore, the famous philosopher of science Karl Popper proposed that the criterion for judging whether a theory is scientific is falsifiability. That is to say, a theory is unscientific as long as it finds an inconsistent phenomenon, but it is scientific in the corresponding field until it cannot be found.

Science has never considered everything in the world, nor that it can explain everything, but only as a way to explore the world carefully and rigorously.

It can even be said that science is just an imagination, an extremely rigorous, careful, and interlocking imagination, and before the flaws of this imagination cannot be found, it is the truth.

The reason why scientific imagination can be so rigorous, careful, and interlocking is because it is based on mathematics.

All imagination starts from the simplest mathematics, from the digital operation of 1+1=2.

Only if you think that 1+1=2 is right, there will be integers, prime numbers, exponents, calculus, functions, relativity, nuclear physics, quantum science and everything else.

Just like Newton defined F, m, and a, only then did F=m*a.

No one has peeped into the principles of the world, but mathematics assumes and simulates the principles of the world.

This is mathematics, and this is the most useful thing.

If a person can learn mathematics well, it means that he has the most powerful ability - the ability to see the essence of the world.

Therefore, the most advanced fields on the modern earth, such as rockets, satellites, nuclear weapons, and finance, do not require mathematics.

Mathematics is what is really useful, the key to truth.

After thinking about it, Li Cha decided to teach Pandora mathematics.

Thus, there is Pandora who is now possessed like a demon.

Considering the foundation of Pandora, Li Cha did not teach difficult knowledge as soon as he came up. Things like quadratic equations, geometry, and definite integrals were all thrown aside. Instead, he started with the difficulty of choosing an elementary school on the modern earth.

Li Cha's teaching is... the four arithmetic operations.

To be honest, it is not all of the four arithmetic operations, but a part of them. It is the experience summed up in ancient calculations in China, and the absolute essence of mathematics invented in the Spring and Autumn and Warring States periods-the only existence in the world.

Well, ninety-nine table.

One gets one.

One two is two, two two is four.

One three makes three, two three makes six...

From the first day when he left Baishi City, Professor Li Cha gave Pandora all the ninety-nine forms, and Pandora has been digesting them ever since.

One day, two days, three days... As of today, it has been five days.

For the past five days, Pandora tried hard to remember.
