Learn about the 5 most important mathematical equations that changed our knowledge of the world | Science

Mathematics is a very brief language and we can all understand what each letter in it is

What differentiates the letters and symbols found in mathematical equations is that they have a limited amount of language, the meanings of which vary from one culture to another when we use words, but mathematics is a very concise language. This way we can all understand what each letter in it is.

Although simplicity and elegance are expressed in each mathematical equation, its results are enormous, with some equations that you can write in less than a page will accurately describe your route in the car in a full working day and predict the minute you will arrive home. .

Therefore, equations have always been the most powerful tool of science, and in this article we rely on the book “In Pursuit of Anton: 17 Equations Changed the World” by British mathematician and author Ian Stewart to present 5 equations. Changed the shape of the world.

Mass and energy

According to Albert Einstein’s theory of special relativity, the most famous equation in the history of science to date appears to be the mass “M” (M) multiplied by the energy square with the symbol “E” (E). The speed of light is “C” (C), and the mass and energy of that equation are two sides of the same coin, so we can use it to convert a small amount of matter into a large amount of energy, and this is clearly shown in the atom.

Phitagors theory

It is not known exactly when the Pythagorean theorem appeared. Some historians believe that it originated a thousand years before the birth of the Greek mathematician Pythagoras of Samos (570-495 BC). In any right triangle the angle on both sides of a right angle is equal to the square of the hypotenuse.

We know that this equation is fundamental to almost everything in our lives, for example in the engineering of buildings and bridges, and in controlling distances in survey work, you can see its impact under Albert Einstein’s theory of relativity.

Maxwell’s equations

Even if you do not know, you are now using Maxwell’s equations. They describe the rules by which electricity and magnets operate on your phone and the light that comes to your face. These equations provide a mathematical model for electrical and optical. And radio technologies, such as electric power generation, electric motors, wireless communication, lenses and radar.

From this idea you can understand the significance of the so-called “Maxwell equations” because they were compiled in the 19th century by the Scottish physicist James Clark Maxwell and contributed by many scientists.

Schrங்கdinger equation

Developed by the Austrian physicist Erwin Schrங்கரdinger in 1933, it is an equation that describes how a quantum state changes into a physical system over time, and is important for Newton’s law of second motion, that when a force acts on a body, it accelerates inversely proportional to its mass and vice versa.

The “quantum state” is the strangest thing in physics, in which a subatomic particle has all its possibilities together. There is a thought experiment called “Schrங்கdinger’s Cat” that illustrates that idea. In the experiment, a cat is placed. The closed box containing 50% of the radioactive material decomposes and kills the cat, where the principle of quantum superposition sees the cat alive and dead because the atom in quantum mechanics is decomposed and immortal. At the same time the role of the Schrங்கdinger equation is to predict the final result of such systems in the language of probabilities.

The law of universal gravitation

In this law, reached by Isaac Newton 200 years ago, we find that the ratio of gravity between two bodies is directly proportional to their mass “M” and inversely proportional to the square of the distance “R” (R) between them. ), For this reason, if the moon were slightly closer to the earth he would have fallen into it, and if he had moved a little farther from it he would have flown into space forever.

In its simplicity, the law of global gravity allows us to create accurate descriptions of all the planets, moons, asteroids, and comets in the solar system, and has been used for dozens of years to describe our entire solar system. To travel to its suburbs, it is a force, rather a fragmentation of space.
