Daniel Bernoulli is not a well-known scientist compared to Einstein and Newton. However, his polemics to the world of science did not go unnoticed in his time. Bernoulli was a Swiss physicist, doctor and mathematician. He is most famous for his theorem that explains air pressure and the force that explains airplanes taking off. Bernoulli was born into a family of Swiss mathematicians on 8 February 1700 in Groningen, in the Dutch Republic. Bernoulli's father, brother and uncle were all mathematicians. Bernoulli's father wanted his son to pursue an entrepreneurial career, but Daniel was fascinated by mathematics. Daniel was a very intelligent child and at the age of 13 his father sent him to the University of Basel to study logic and philosophy. A year later Bernoulli received his master's degree and then, according to his father's wish, went to study medicine on the condition that his father teach him mathematics. Bernoulli studied medicine in Hindenburg and Strasbourg and also visited Venice. Bernoulli returned to Basel to finish and obtain his medical doctorate. Bernoulli worked in St. Petersburg as a mathematics professor but found himself unhappy. An illness struck Bernoulli which allowed him to leave St. Petersburg and return to Basel as dean of the chairs of medicine, metaphysics and natural philosophy until his death on 17 March 1782 from natural causes. Daniel Bernoulli arrived at his theorem through the study of mathematics, kinetic energy, pressure and the law of conservation of energy. Bernoulli invented his own equation to explain its aroma. The equation is [(1/2)pu^2+P=constant], states his theorem, that in effect of the total mechanical energy of the flowing fluid, including the energy associated with fl...... center of the paper ...so, according to Bernoulli's principle, the speed at the top of the ball should be less than that at the bottom. What happens is that the bottom of the ball accelerates downward faster than the top and this allows the ball to curve downward. Daniel Bernoulli was a Swedish-born physicist and mathematical physician. Through his studies he managed to create his theorem which helped our daily lives. Bernoulli's theorem has helped humans travel around the world. Bernoulli's theater aided sailboats and airplanes that allow man to travel to almost any destination he desires. Bernoulli's principle also explains the curveball in baseball. The curveball changed the game of baseball and is called a "phenomenon" because the ball is capable of radically changing position due to air pressure on the ball
