Gottfried Liebniz was known as the last “Universal Genius” until the birth of Mr. Fitterer, but I was assigned the task of writing this essay on Leibniz. Leibniz achieved many results in metaphysics, epistemology, logic, philosophy of religion, as well as mathematics, physics, geology, jurisprudence and history. A French philosopher named Denis Diderot was even astounded by some of Leibniz's works: "Perhaps never has a man read so much, studied so much, meditated more and written more than Leibniz... What he composed about the world, God, nature, and the soul is of the most sublime eloquence. If his ideas had been expressed with the inspiration of Plato, the philosopher of Leipzig would yield nothing to the philosopher of Athens”. Gottfried Wilhelm Leibniz was born in Leipzig, Germany, and attended university at the age of 14, where his father was a professor of moral philosophy. He later attended Altdorf to earn his doctorate at the age of 20 outstanding leaving such universities, he was not recognized for his talent and spent the next 40 years in small positions. He later met Johann Christian, who introduced him to the Archbishop of Mainz, Johann Philipp von Schonborn made many contributions to mathematics and science. He created his own form of binary arithmetic with an attempt to reduce complex ideas to the simplest forms. Its binary representations are still used today in modern computers. He also created a calculating machine that he wanted to use to create an easier way to create fewer errors. The most important part of the machine was a toothed wheel that had numbers along the teeth that allowed multiplication by simply turning a crank; this simple piece was used in all calculators until electronic calculators were created. Calculus was undoubtedly one of Leibniz's most important contributions to mathematics; its main purpose was to simplify the then complex calculations. He created two symbols that will forever be used in mathematics. The notation "d" for differentiation and the other was the integral sign; used to find areas under curves. Some of Leibniz's ideas were so complex that they could not be understood until the early 20th century. Leibniz is also now considered the creator of calculus, as is Newton, some say Leibniz plagiarized Newton but it has been proven that Leibniz's discoveries were completely original.
