Isaac Newton

Speaking of Isaac Newton implies reviewing some theories that are still in force and that are the fundamental basis of much of the scientific and physical advances of the moment. Each discovery was accepted and even his mathematical calculations were used by other scientists of the time within his experiments.

Something that speaks of the incredible qualities and capacities that he had in life. For this reason, on this occasion we would like to talk a little about the history of Isaac Newton and his time in science. In addition to mentioning the laws of physics that explain in depth his theory of universal gravity.

Who was Isaac Newton?

Isaac Newton is born in England on December 25, 1642. He never knew his father since he died before his birth. The first years of his life were spent with his mother, but when he got married, he decided to leave the child with his grandparents.

Since then, his learning and teaching was surrounded by different mentors who, unintentionally, led him to have an interest in science. On the other hand, when Newton was 12 years old, he went to live with the pharmacist William Clarke, who had the best library of the time and the one that inspired much of the young man's experiments.

There arose his interest in sundials and what in turn allowed him to base his first discoveries on a wall clock with equations. This hobby led him to determine and find the exact moments of solstices and equinoxes, among other things.

At the age of 16 he was already experimenting with the wind and determining its strength by the distance he traveled between each jump. From then on, his life focused on taking care of his family's farm, until in 1660 he was sent to Cambridge to start his university studies.

What did Isaac Newton discover?

Isaac Newton had the opportunity to build the first reflecting telescope that gave way to his theories, among which are Newton's laws and the Law of gravity.

At this point, the question of who discovered gravity remains open since, before the emergence of the Newtonian theory, other physicists and astronomers were already trying to explain the reasons for the movements of the stars.

The main exponents were Copernicus, Kepler and Galileo, who were left behind due to the advances of Newton. He claimed that the bodies were attracted by a balanced force and equal in mass.

Discovery that is constituted by Newton and the famous apple that he saw fall in 1666 from a tree on his farm. Hence the Newtonian theory of gravity that explains the lunar orbit in relation to the earth, and that of the planets around the sun.

However, to reach this conclusion and establish the laws of attraction, he had to resort to other mathematical elements. Giving thus, with the invention of the differential and integral calculus of mathematics.

In short, Isaac Newton proposed the universal law of gravity, advances in mechanics, mathematics, optics and astrophysics. As if that were not enough, he creates the theory of the nature of light that is presented in detail in the Treatise on Optics of 1704.
