ISAAC NEWTON AND GOTTFRIED LEIBNIZ

IISAAC NEWTON (1642 - 1727)

British mathematician and scientific, and co-inventor of calculus, in a two years period (1642 – 1727), Newton made important  and fundamental contribution to calculus and optical, besides being the discovered of the universal gravitation law,  he did not publish his discoveries from the first moment, only introduced his results as  useful tools into his scientific papers.

His work “mathematical principles of natural philosophy” is considered as one of the greatest achievements of human thought.

Gottfried Leibniz  (1646 - 1716)

German mathematician and philosopher who introduced much of the terminology and notation of calculus, terminology that was created by the same, at the same time that Sir Isaac Newton. At 20 years old, Leibniz was a prodigal, he was a lawyer and had published papers about logic and jurisprudence, He was a real man of Renaissance, and he was possessor of an extraordinary library, and contributed to politics, to philosophy, technology, engineering, linguistics, geology, architecture and physics. In mathematics, he deduced fundamental rules for derivation and promoted the development of calculus through its extensive communications by letter. The notation he presented are logical and simple, and have been barely improved in the last 300 years, these notation make calculus more accessible. 

One of the phrases he wrote:

"The symbols shown an advantage in discoveries, even greater when they express with brevity the exact nature of something . . . , thus decreasing the effort of thought."
