No. 10 the length of the circumference.

Founder: the ancients

Meaning: Mathematical expression of the beauty of nature.

This formula is awesome. I have been learning it since junior high school. At present, human beings have been able to obtain the precision of 206 1 100 million bits of pi. Still pretty boring. A dozen -pi values used in modern science and technology are enough. If the value of -pi with 35-bit precision is used to calculate the circumference of a circle that can enclose the solar system, the error is less than one millionth of the proton diameter. Nowadays, people calculate pi mostly to verify the computing power of computers and also for interest.

Fourier transform No.9 (Fourier transform)

Founder: jean baptiste joseph fourier

Meaning: Any irregular signal can be expressed as infinite superposition of regular sine waves. It is an important method in digital signal processing field.

This is quite professional, and most people don't understand it at all. Not much to explain. In short, there would be no electronic computer today without this formula, so you can thank the party and the government for surfing the Internet here, and also thank this formula that you can't understand at all. In addition, although Fourier's surname is Fu, he is French.

8. De Broglie relationship

Founder: Louis Victor de Broglie

Significance: De Broglie believes that any substance has both particle and fluctuation, or that any substance can also be regarded as a wave, including human itself. Man exists not only as a substance, but also as a wave in a sense.

This thing is also pretty awesome. In the case of physics optics in high school, many concepts are distant relatives with it. In short, de Broglie thinks that electrons are not only particles, but also waves, which have "wavelengths". So we get this equation of matter wave, which expresses the relationship between wavelength, energy and so on. At the same time, he won the 1929 Nobel Prize in Physics.

No.7 1+ 1=2

This formula needs no name, translation or explanation.

Schrodinger equation No.6 (Schrodinger equation)

Founder: Erwin Schr?dinger

Meaning: In quantum mechanics, the state of an object cannot be described by displacement, velocity, etc. Just like in classical mechanics, but only a function of physical quantities. This physical quantity is no longer a certain value, but a probability distributed with time, and each microscopic system has a corresponding Schrodinger equation. The significance of Schrodinger equation in quantum mechanics is the same as that of Newton's second law in classical mechanics.

It is also completely incomprehensible to ordinary people. So I extract the official comment: "Schrodinger equation is the most widely used and influential formula in the world atomic physics literature." For his outstanding contribution to quantum mechanics, Schrodinger won the 1933 Nobel Prize in Physics. In addition, although Schrodinger is surnamed Xue, he is Austrian.

No.5 mass-energy equation (mass-energy equivalent)

Founder: Albert Einstein

Significance: The mass-energy equation profoundly reveals the relationship between mass and energy. Before that, people undoubtedly thought that quality was quality and energy was energy, and there was no connection between them. It was the discovery of the mass-energy equation that led to the explosion of atomic bombs and hydrogen bombs. More importantly, this equation completely subverts the inherent thinking of human beings and promotes the progress of human civilization.

It seems that there has never been a scientific formula with such a broad meaning. Physics 1905 "miracle year" was put forward by a young man named Einstein. In the same year, he also published "On Electrodynamics of Moving Objects"-commonly known as Special Relativity. This formula tells us that Einstein is awesome and that energy and mass are interchangeable. By-product: atomic bomb.

The fourth pythagorean theorem/pythagorean theorem

Founder: Pythagoras (some people think that Pythagoras theorem has appeared and proved in China Shang Dynasty)

Significance: Pythagorean theorem is a typical method to solve graphic problems by mathematical methods. At present, there are more than 400 certificates. Hook three strands, four strings and five are so deep into the hearts of people on earth.

It is impossible to do math without it, so I won't say more.

The third Newton's second law of motion

Founder: isaac newton

Significance: Newton's second law is the core of classical physics, which is applicable to all aspects of our daily life and marks the beginning of real physics research. Without Newton, human civilization would have spent more time in the dark world. One of the greatest scientists of all time is regarded as one of the greatest core laws in classical physics in the greatest scientific masterpiece Mathematical Principles of Natural Philosophy. All the basic equations of power can be derived from them by calculus. For those who have studied physics in high school, there is nothing to say.

The second Euler identity

Founder: leonhard euler

Significance: Many formulas in mathematics were discovered by Euler, so Euler formula is not a single formula, and Euler formula is widely distributed in all branches of mathematics. Charles Kleiber, Secretary of State for Education and Research in Switzerland, once said, "Without many scientific discoveries made by Euler, our life today would be completely different." Laplace, a French mathematician, thinks that reading Euler is everyone's teacher.

Did God write this formula? In the last few places, the creators are all gods. Euler is the most prolific mathematician in history, and also a scholar who has written the most books in various fields (including mathematics and mechanics, optics, acoustics, water conservancy, astronomy, chemistry, medicine and so on). ). In the history of mathematics,18th century is called "Euler era".

Born in Switzerland, Euler was blind in his right eye at the age of 3/kloc-0 and at the age of 59, but he was optimistic, with amazing memory and concentration. He was humble all his life and seldom named what he found with his own name. However, one of the most important constants -e is named.

The genius of this formula is that it has no redundant content. Put the most basic E, I and pie in the same formula, add 0 and 1 at the same time, which is also the most important in mathematics and philosophy, and then connect them with a simple plus sign.

Gauss once said: "A person can't become a mathematician when he first sees this formula and doesn't feel its charm."

Maxwell equations No.65438 +0 (Maxwell equations)

Founder: james clerk maxwell

Significance: organically unify the electric field and magnetic field into a complete electromagnetic field. And established the electromagnetic field theory, without which there would be no present social civilization. Those who can understand these formulas must feel a cool breeze behind them-if there is no God, how can such a perfect equation be explained?

This set of formulas combines the Gauss law of electricity, Gauss law of magnetism, Faraday law and Ampere law.

A modest evaluation is: "Generally speaking, any electromagnetic phenomena in the universe can be explained by this set of equations." Later, Maxwell predicted the existence of electromagnetic waves from this set of formulas only by paper-and-pencil calculus.

Don't we all like to make up stories, for example, when Einstein was a child, he embarked on the road of studying hard to serve the motherland because of some stimulation? In fact, this stimulus is the equations you see. It is precisely because this set of equations perfectly unifies the whole electromagnetic field that Einstein has always wanted to unify the gravitational field in the same way, putting the macroscopic force and the microscopic force in the same set: the famous "grand unification theory".

Einstein never walked out of this tunnel until his death. If he did, we would see God himself at the other end of the tunnel.
