Magus Tech

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

This is a large room with an area of ​​tens of square meters, all corners are clean and clean, the bedding on the bed is newly changed, and the air is filled with a light floral fragrance, giving a comfortable feeling .

Richard nodded with satisfaction and sat down on the table.Pandora walked straight to the soft bed, eyes straight, as if enchanted, "slammed" sitting on the bed all at once, staying the same without saying a word, constantly dazed.

Pandora has been like this for several days.

The reason for this is that, after leaving the White Rock City to spend the initial excitement, Pandora thought of her experience in White Rock City and thought she was very useless.It’s a little sad to learn nothing and not fight.

After some serious thinking, Pandora very solemnly made a request to Richard, that is, I hope to learn something really useful from Richard, and there will be similar situations in the future, but it will not come in handy.

Really useful!

Pandora particularly emphasized the tone and emphasized these four words.

After studying it, Richard found that Pandora was not kidding, but really thought.

Something really useful?

What is really useful?

Are combat skills useful and useless?It's very useful, but you don't need combat skills to do experiments. Even if you are a master of combat, it won't help you to do experiments, so Pandora sometimes frustrates.

Is it useful to experiment?It's very useful, but it doesn't improve the combat effectiveness by doing experiments. It's just a waste of Pandora's powerful combat power.

To be honest, many useful things are one-sided and limited, and can only play a role in one field or several fields. Once it exceeds this range, there is no use.

Even scientific knowledge is like this.

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

A person has an outstanding contribution in the field of mechanical production, so he will not be able to start when he changes his career to cultivate cells.

What is really useful?What is the thing that can be applied in any place without any restrictions after learning?

In other words, what is the essence of science?What is the core of everything?

There is only one answer, that is-mathematics.

Well, math.

The whole world, the bottom of the whole rational and scientific world, has an unshakable cornerstone, that is, mathematics.Only on the cornerstone of mathematics will there be knowledge of disciplines such as physics, chemistry, and biology.

The whole world, the truth of the whole world, every law and formula are built on the basis of mathematics.

For example, Newton developed Newton’s second law: 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 simple and sacred formula, in the field of classical mechanics, nothing can be violated.

But why is this formula like this?Why can Newton say this formula so accurately, he opened the whole world and peeked into the real world principle?

Obviously not.

In fact, the Bulls did not peep into any world principle. The reason for this formula is because he first defined F, m, and a, and then combined them into a formula.

Similarly, if he likes it, he can make the formula a little more complicated, such as F=d*t*g, or W=5h*r*k*2472.

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 what the basic concept is changed, in this system, the interior is self-consistent and can be used to explain the phenomenon of movement.

So, it was not Newton who discovered the principle of the world at all, but he made a hypothesis and then just explained the phenomenon of the world.

In the same way, the rest of the disciplines are almost the same. The entire system is constructed from top to bottom. Inside them, they are self-consistent, and the outside can explain the performance of the world's operation to the maximum.

This is how the entire set of technology is produced.

First assume the hypothesis, then verify, and finally become the theorem.

Therefore, the famous philosopher of science Karl Popper proposed that the criterion for judging whether a theory (proposition) is scientific is Falsifiability.That is, a theory, as long as it finds a phenomenon that is not consistent, it is unscientific, but before it is not found, it is scientific in the corresponding field.

Science never considers everything in the world, does not think 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 it is the truth before the flaws of this imagination can be found.

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

All imagination starts with the simplest mathematics, and starts with 1+1=2 digital operations.

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

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

No one peeks 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 math well, it means that he has the most powerful ability-the ability to see through the essence of the world.

Therefore, rockets, satellites, nuclear weapons, and finance do not require mathematics in the most advanced fields of modern earth.

Mathematics is really useful and the key to truth.

After this thought, Richard decided to teach Pandora mathematics.

As a result, there is Pandora who is now enchanted.

Considering Pandora's foundation, Richard didn't teach difficult knowledge as soon as he came up. Things like unary quadratic equations, geometry, definite integrals, etc. were thrown aside. Instead, he started with the difficulty of selecting elementary schools on modern earth.

Professor Richard's is... Four operations.

To be honest, it is not all of the four operations, but a part of it. It is the experience that China has summed up in ancient calculations, the absolute essence of mathematics invented in the Spring and Autumn Period and the Warring States Period, the only one in the world.

Um, Jiujiu watch.

One by one.

One two gets two, two two gets four.

One three gets three, two three gets six...

From the first day of leaving White Rock City, Professor Richard gave Pandora all the Jiujiu watches, and Pandora has been digesting it.

One day, two days, three days...Today, it has been five days.

These five days, Pandora tried hard to remember.
