Pythagoras was born on the Greek island of Samos, off the Ionian coast, in 570 BC. Ç. He studied mathematics, astronomy, music, literature and philosophy in his hometown.

He was guided in the Greek city of Miletus by one of the greatest pre-Socratic philosophers: Miletus Tales.

Pythagoreanism

According to Pythagoras, numbers are the basis of life on earth. From that firstfruits, the Pythagoreanism (or Pythagorean School), being the Pythagoreans his followers, among which the following stand out: Themistocleia, Philolaus of Crotona, Archytas of Tarento, Alcmeão and Melissa.

At school, he taught in the areas of mathematics (arithmetic and geometry), astronomy, music, philosophy, politics, religion and morals.

According to the Greek mathematician, numbers represented harmony and order, that is, they were considered the essence of all things.

This theory of Pythagoras arose from the observation between the harmony of musical chords.

The Pythagoreans believed that this conception was not merely mathematical but also mystical and spiritual.

In this sense, they developed a spiritual conception of human existence, where the soul is freed from the body after death.

That is, they believed in reincarnation and the development of human virtues while the soul was imprisoned in the body during life.

As a result, men could reincarnate in a higher form of existence, according to the virtues gained during the earthly trajectory.

In addition to the famous "Theorem of Pythagoras", the Pythagoreans discovered figured numbers and perfect numbers.

In the field of astronomy, Pythagoras also put forward questions about the sphericity of planet Earth and the displacement of the stars using mathematical concepts.

This theory based on a harmonic cosmos became known as "Theory of Harmony of the Spheres".

Pythagorean theorem

One of the most important theorems of geometry is the Pythagorean theorem. It is represented by the formula (c²= a²+b²) and its statement is described as follows:

"In the right triangle, composed of an internal angle of 90° (right angle), the sum of the squares of its legs corresponds to the square of its hypotenuse."

This formula is valid to calculate the size of the right triangles and it has a myriad of applications especially in construction in general.
