Key Points

Daniel Bernoulli (1700–1782):-
- He was a Swiss mathematician and physicist.
- He is best known for his applications of mathematics to mechanics, especially fluid mechanics, and for his pioneering work in probability and statistics.
- His name is prominently remembered through the principle of Bernoulli's equation, which describes the behavior of fluid flow.

Additional Information

Evangelista Torricelli (1608-1647):-
- He was an Italian physicist and mathematician, best known for his invention of the barometer, an instrument used to measure atmospheric pressure.
- This invention played a significant role in the development of the field of fluid dynamics.
Blaise Pascal (1623–1662):-
- He was a French mathematician, physicist, inventor, philosopher, and writer, who made significant contributions to various fields:
Jean Léonard Marie Poiseuille:-
- He was a French physicist and physiologist who is most known for his research in the field of fluid dynamics.
- He was born in Paris on April 22, 1797, and died there on December 26, 1869.
