WHO WAS BERNOULLI ?

 

Bernoulli

Daniel Bernoulli was born in Feb. 8  1700. He investigated not only mathematics but also such fields as medicine, biology,  mechanics, physics and astronomy. Bernoulli’s theorem, which he derived, is named after him. HE  was the second son of Johann Bernoulli, who first taught him mathematics. Bernoulli’s father  was a qualified medical doctor and brilliant mathematician, one of the first to master and expand the new mathematics of calculus.  Bernoulli studied  philosophy, logic, and medicine at the universities of Heidelberg, Strasbourg, and Basel, he received an M.D. degree (1721).

                                        

In 1723 Bernoulli moved to Venice, Italy to learn practical medicine. He visited patients and worked in hospitals alongside doctors. He also spent time at the opera, theater, and fancy-dress parties.However, he could not abandon his love of mathematics , particularly applied mathematics. He was eager to unravel secrets of the universe, following in the footsteps of Galileo and Newton.Bernoulli carried out fluid mechanics experiments in which he measured water flowing out of a vessel. He noticed water flowed out faster as the height of the liquid in the vessel was increased. He established a mathematical relationship between the height of the water in the vessel and its pressure and its velocity flowing from the vessel. He also looked at the situation from the viewpoint of converting potential energy to kinetic energy.

The Bernoulli Effect

Bernoulli returned to the ideas he had first learned from his father and developed them. He applied the idea of energy conservation to fluids in motion.In doing so he discovered The Bernoulli Effect, the discovery he is most famous for, that when a fluid flows through a region in which its speed increases, its pressure will fall. He correctly described the effect mathematically.The Bernoulli Effect has many real-life applications and is often cited as the reason aircraft wings provide lift.

He lived for his work; he never married and had no children. Bernoulli respected simplicity of lifestyle and frugality, but not meanness. Daniel Bernoulli left the world at the  age of  82 on March 17, 1782 at Basel, Switzerland.
