At the end of the second floor, inside the room.
This is a large room, with an area of dozens of square meters. Every corner is cleaned, the bedding on the bed is newly changed, and the air is filled with a light floral fragrance, giving people a comfortable feeling. .
Richard nodded with satisfaction and sat down on the table. Pandora walked straight to the soft bed, her eyes were straight, as if she was possessed, and she sat down on the bed without saying a word.
Pandora has been like this for several days.
The reason for this is because after the initial excitement of leaving White Rock City, Pandora felt that she was very useless when she thought of her experience in White Rock City. 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 Richard, that is, she hoped to learn something really useful from Richard, so as to avoid similar situations in the future but not being able to use them.
Really useful!
Pandora emphasized these four words with a particularly strong tone.
After some research, Richard found that Pandora was not joking, but was actually thinking about it.
Something really useful
What is really useful
Are combat skills useful? It is very useful, but doing experiments does not require combat skills. Even if you are a combat master, it will not be of any help in doing experiments, which is why Pandora is sometimes frustrated.
Is it useful to conduct experiments? It is very useful, but if you make flowers through experiments, the combat effectiveness will not be improved in any way. Just letting Pandora do the experiment is actually a waste of Pandora's powerful combat effectiveness.
To be honest, many useful things are one-sided and limited, and can only play a role in one or several fields. Once they exceed this scope, they are of no use.
Even scientific knowledge is like this.
A person is powerful in the biological field, but if he is thrown into a mechanical factory, he will be helpless.
Even if a person has made outstanding contributions in the field of mechanical manufacturing and changes his career to cultivating cells, he will not be able to start.
What is really useful? What is something that once learned, can be applied anywhere without any restrictions
In other words, what is the essence of science? What is at the heart of it all
There is only one answer, and that is mathematics.
Well, math.
At the bottom of the entire world, the entire rational and scientific world, there is an unshakable cornerstone, and that is mathematics. On the basis of mathematics, there is knowledge of physics, chemistry, biology and other subjects.
The entire world, the truth of the entire world, every law and formula are built based on mathematics.
For example, Newton studied Newton's second law: the acceleration of an object is directly proportional to the force, inversely proportional to the mass of the object, and directly proportional to the reciprocal of the mass of the object;
That is F=m*a.
F=m*a, what a simple and sacred formula, nothing can violate it in the field of classical mechanics.
But why is this formula like this? Why was Newton able to state this formula so accurately? Did he peel back the entire world and get a glimpse of the real world principle
Apparently not.
In fact, Niu Dui did not get a glimpse of any world principle. The reason why he has this formula is because 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 more complicated, such as F=d*t*g, or W=5h*r*k*￥/2472.
In this case, all the basic concepts of classical mechanics may need to be replaced to explain the letters in the formula. But no matter how the basic concept is changed, in this system, it is internally self-consistent and can be used to explain the phenomenon of motion.
Therefore, it is not that Newton discovered the principles of the world at all, but that he put forward a hypothesis and then explained the phenomena of the world.
In the same way, other disciplines are almost like this. The entire system is constructed from top to bottom. Internally, it is self-consistent, and externally, it can explain the various manifestations of the world to the maximum extent.
This is how the entire technology came about.
First it is a hypothesis, then it is verified, and finally it becomes a 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 is unscientific as long as it finds a phenomenon that does not conform to it, but it is scientific in the corresponding field until it cannot be found.
Science is never thought to be everything in the world, nor is it thought to be able to explain everything, but only as a careful and rigorous way to explore the world.
It can even be said that science is just an imagination, an extremely rigorous, careful, and interlocking imagination, and until 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, starting from the number operation of 1+1=2.
Only if you think that 1+1=2 is right, will there be integers, prime numbers, exponents, calculus, functions, relativity, nuclear physics, quantum science and everything else.
Just like Newton defined F, m, and a, F=m*a.
No one has a glimpse of 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 through the essence of the world.
Therefore, the most advanced fields on the modern earth, including rockets, satellites, nuclear weapons, and finance, do not require mathematics.
Mathematics is something truly useful and the key to truth.
After thinking about it, Richard decided to teach Pandora mathematics.
As a result, there was Pandora who is now possessed.
Considering the basics of Pandora, Richard did not teach difficult knowledge right from the beginning. Things like quadratic equations, geometry, definite integrals, etc. were all thrown aside. Instead, he started by choosing the difficulty level of elementary school on modern earth.
What Richard teaches is... the four arithmetic operations.
To be honest, they are not all of the four arithmetic operations, but a part. They are the experience summed up by China in ancient calculations, and the absolute essence of mathematics invented in the Spring and Autumn Period and the Warring States Period - the only existence in the world.
Well, ninety-nine watches.
One for one gets one.
One two makes two, two two makes four.
One three makes three, two three makes six...
From the first day he left White Rock City, Richard taught Pandora all the Nine-Nine Watches, and Pandora has been digesting them ever since.
One day, two days, three days... As of today, it has been five days.
During these five days, Pandora tried hard to remember.
