Daniel Bernoulli

Bernoulli's principles is named after the Swiss scientist Daniel Bernoulli who published his principle in his book

Hydrodynamic in 1738.

Daniel Bernoulli was a Dutch-born member of the Swiss mathematical family. His most important work considered the basic properties of fluid, pressure, density and velocity, and gave the Bernoulli principle.

Daniel Bernoulli states that as the speed of moving fluid (liquid or gas) increases, the pressure within the fluid decreases. He used the conservation of energy as well as pumps and other machines that are used to raise water with this principle. Daniel Bernoulli, son of Johann I, was born on Groniengen, Netherlands. Of all the Bernoullis, he was perhaps the greatest mathematician. Daniel also had widest interests which includes medicine, biology, physics, mechanics, and astronomy. Daniel originally planned a career business and medicine. Like other family members, however, he was drawn to the field of mathematics. Between 1725 and 1732, he taught mathematics at the Academy of Science in St. Petersburg, Russia. He then went to the University of Basel, where he taught anatomy, botany and then physics. Daniel's most important work was in mechanics. He was the founder of the science of hydrodynamics, the study of moving fluids. One of his main contributions in this area is Bernoulli's Principle, which states that the pressure in a fluid decreases as its velocity, or speed, increases. Daniel is also noted for his work in calculus and probability theory, especially as it applies to games. He is also considered on of the founders of the kinetic theory of gases, which helps explain the property and behavior of gases. Between 1725 and 1749, Daniel won many prizes for his work on astronomy, gravity, tides, magnetism, and ocean currents.
