Sample text

Aristotle’s primary philosophy was based in nature, and he believed that everything could easily, and logically, be explained through observation. It was this application of logic to his observations that made it possible for Aristotle to devise such convincing explanations that his ideas became intellectually irreproachable. , upon Plato’s death, Aristotle was not named to succeed his teacher as the head 25 of the Academy. Dedicated to learning, he began a personal journey of acquiring and collecting knowledge, writing down his observations and thoughts on topics ranging from biology and zoology, to logic and politics.

Based on his specifications, the two proved his theory of light, in which the velocity of light decreases as it passes through a denser medium. Arago died shortly thereafter. During his lifetime, Arago became a political figure campaigning for liberal reform in the French government. He was appointed as minister of war and marine, and is credited for eliminating slavery throughout the colonies. He has been honored for his lifetime contribution to science in many ways. Several Parisian streets bare his name, and he is one of 72 scientists commemorated with a plaque in the Eiffel Tower.

The discovery of Neptune, in 1846, is as tied to Arago as it is to JOHN COUCH ADAMS, Sir George Airy, and URBAIN-JEAN-JOSEPH LE VERRIER. Arago suspected in 1845 that the anomalies in Uranus’s orbit were cause by an asyet-undiscovered planet. Arago assigned the task of finding the planet to LeVerrier, who published his papers before Adams and won credit for the new planet, which Arago participated in naming. When the great scandal took place over the ownership of discovery, all of France, especially Arago, staunchly defended LeVerrier’s claim.
