Isaac Newton: his main contributions to science | Digital Trends Spanish


The mathematician and physicist Joseph Louis Lagrange said of Isaac Newton that he was “the greatest genius that ever lived and also the luckiest since a system that rules the world can only be found once.”

Thus, many times the English physicist, theologian, mathematician and inventor has been considered one of the greatest scientists of all time and his work has been called as the culmination of the scientific revolution.

Isaac Newton was born precisely on January 4, 1643 in Woolsthorpe, England, and his exquisite legacy can be analyzed from his two main works.

Principle, from 1687, is considered his most important work. In this work, Newton established the three laws that govern the motion of bodies.

He also studied the force that exists between the Earth and the Moon, a force that turns out to be proportional to each of the masses and inversely proportional to the square of the distance between both bodies.

The English physicist was able to extend this law to all bodies in the universe, thereby establishing the Law of Universal Gravitation.

Meanwhile, in his work Opticks (1704) Newton formulated the corpuscular theory of light and the theory of color.

Another of the contributions of the mathematician was the introduction of differential and integral calculus. Gottfried Leibniz also discovered the infinitesimal calculus independently of Newton, for which both were linked to a kind of controversy that lasted until the death of the German, in 1716.

Reflector

In 1672, Newton presented to the Royal Society of London the first reflector telescope of practical utility, thus giving a revolutionary impetus to the technical development of the telescope.

His device had a mirror about three centimeters in diameter, located inside a six-inch long tube.

Since it had no lenses, the telescope did not suffer from chromatic aberration and could be as powerful as a refractor ten times as long. Thus, its design could solve technical problems of refractors.

However, technology was not yet ready to build this type of reflecting telescopes, so it had to wait until William Herschel (1738-1822), who built the first large telescopes.

The above demonstrates once again the greatness of Isaac Newton and his crucial contribution to the world of science.
