Google has put up a doodle in commemoration to the 306th birthday anniversary of one of the greatest mathematician and physicist to ever exist, Leonhard Euler. The doodle features the Google logo amidst some equations and graphs. The second "O" of the logo animates itself, when clicked on.
Swiss mathematician and physicist, Leonhard Euler is highly acclaimed, for his contributions infinitesimal calculus and graph theory. He is also known to have introduced most of the modern mathematical terminology and notations. His contributions does not just limit to mathematics, as he is also renowned for his works in mechanics, fluid dynamics, optics, and astronomy.
Leonhard Euler was born on April 15, 1707, in Basel. After Leonhard's birth, his family moved out of Basel and into the town of Riehen. It was here, where Leonhard's father, Paul Euler, befriended Johann Bernoulli, who was then regarded as Europe's foremost mathematician, at that time. Leonhard began to study Philosophy at the University of Basel, at an early age of 13. He would stay with his maternal grandmother, until he got his master's digree. During his studies Leonhard started taking lessons in mathematics with Johann Bernoulli, during the weekends. Bernoulli, convinced that Leonhard was destined to be grate mathematician, urged Paul Eulr to let his son go into the world of mathematics and the rest was history.
His work in continuum physics, algebra, lunar theory, trigonometry, geometry, infinitesimal calculus is considered invaluable and is often used as context of reference for a wide range topics. Euler was featured on the sixth series of the Swiss 10 franc banknote. There were also numerous Swiss, German, and Russian postage stamps released in his honor.
