The Application of Mathematics in War

Don't look at the mess of copying the party (time and strategic games are not mathematics), and you don't need to listen to those parabolas and hyperbolas (they are all backward things in Chinese math books, the artillery during World War II is like this, and now it is not), with your intuition, you should know that the relationship between mathematics and computers, the relationship between nuclear ** and mathematics, the relationship between aerospace and mathematics, the relationship between intelligence and cryptography and mathematics (these things cannot be learned in Chinese mathematics classes, A lot of people haven't even heard of the concept. ）

If you have some research in mathematics, you can go and look at the Fourier transform (this thing is decisive in signal processing analysis, radar and guidance, the algorithm is ever-changing, the Russians are the most powerful in advanced mathematics, so their S300 anti-aircraft missile built-in software 28K, the American Patriot anti-aircraft missile built-in software 300M, but due to the good algorithm, the actual combat effect of the latter is not as good as the former. ）

Whenever I think about drawing glasses for my grandfather, I can't help but laugh out loud. It was one day during the summer vacation, and I went to my grandfather's house, who was working in the fields. It was too hot, and my grandfather was so tired and sweaty that he had to sit down and rest with his back against a big tree, and he fell asleep unconsciously.

Idle and bored, wandering around, I stared at my grandfather's sleeping face, looked left and right, and an idea crept into my mind. Like a whirlwind, I blew into the house and searched everywhere. Haha, a pen is enough!

I tiptoed closer to my grandfather little by little. Thankfully, Grandpa didn't wake up. I looked at my grandfather's face for a moment and drew two circles centered on my nose.

Oops, it's a little small. "Phew", I spat on my fingers, just about to raise my hand to wipe it. No, if Grandpa wakes up, won't my plan be ruined?

When I think about it, I don't know what to do. Well, let's do it! I picked up the pen and drew a large circle on the outside of the small circle.

Hee-hee, with dark circles under his eyes, Grandpa has become a giant panda. I laughed secretly. Draw a horizontal line, won't it become a pair of glasses?

Well, it's pretty much the same, grandpa is like a college inquirer! On the way home, the neighbors laughed when they saw their grandfather, shook their heads and walked away. Grandpa wondered and said to himself

What's wrong with the neighbors? I was afraid of laughing, so I quickly covered my mouth. As soon as I entered the house, my grandmother laughed, and my parents laughed too.

Hahaha, the cheerful laughter flew out of the window of Grandpa's house and floated far, far away. Grandpa felt that something was wrong, and hurriedly rushed to the mirror, saw his strange appearance, and stared at the big balls. "Now, Grandpa is more like a giant panda.

I looked at my masterpiece and clapped my hands and exclaimed. "You troublemaker! "Grandpa was so angry that his beard curled up, and he rushed over and was about to pull my ear.

Wow, I was like a little loach, scurrying far away, grimacing and laughing. Childhood is naïve, childhood is naïve, childhood is naughty. Now, as long as I think of this interesting story, I can't help but laugh.

Today's wars are all fought by machines, such as missiles, where to launch are to calculate the trajectory, look at which direction is set how many kilometers, in fact, the angle of rotation of the barrel is to be calculated, the use of parabola, which integrates the three aspects of physics, chemistry and mathematics. And physics is largely a mathematically evolved evolution.

The hyperbola calculates the landing point of the shell, and even if a single sniper fires, the wind bias is calculated to adjust the ballistic landing point. and the parabolic trajectories of ballistic missiles, all of which have a myriad of mathematical implications.

To put it simply, in real life, it is often necessary to abstract practical problems into mathematical models, which can be abstracted into more abstract pure theories, and the task of applied mathematicians is mainly to prove that the mathematical theories used in these models are rigorous and correct.

In the final analysis, it is to establish a connection between abstract mathematical theory and actual data processing, and to confirm the rationality of practical methods by proving the correctness of abstract theories.
