Who was Bernoulli and what did he discover?

Bernoulli, Daniel (1700–82) Swiss mathematician and physicist. His work on hydrodynamics demonstrated that pressure in a fluid decreases as the velocity of fluid flow increases. This fact, which explains the lift of an aircraft, became known as Bernoulli’s principle.

What did Daniel Bernoulli contribute to the atomic theory?

In the 1700s Daniel Bernoulli discovered the principle that allows airplanes to fly and found the first evidence for the existence of atoms in gases.

Who invented Torricelli?

Italian physicist and mathematician Evangelista Torricelli, inventor of the mercury barometer. Two years later, pursuing a suggestion by Galileo, he filled a glass tube 4 feet (1.2 m) long with mercury and inverted the tube into a dish.

What is the contribution of Isaac Newton in science?

An influential figure of the Scientific Revolution is Sir Isaac Newton. He made many advancements in the field of science and mathematics, he discovered Gravity, developed the three basic laws of motion, and co-development of Calculus.

Why is Bernoulli’s principle important?

Bernoulli’s principle is valid for any fluid (liquid or gas); it is especially important to fluids moving at a high velocity. Its principle is the basis of venturi scrubbers, thermocompressors, aspirators, and other devices where fluids are moving at high velocities.

What is Jacob Bernoulli famous for?

Jakob Bernoulli, (born January 6, 1655 [December 27, 1654, Old Style], Basel, Switzerland—died August 16, 1705, Basel), first of the Bernoulli family of Swiss mathematicians. He introduced the first principles of the calculus of variation. Bernoulli numbers, a concept that he developed, were named for him.

Who created the first atomic theory?

Dalton’s atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties. Dalton based his theory on the law of conservation of mass and the law of constant composition. The first part of his theory states that all matter is made of atoms, which are indivisible.

Who first invented barometer?

What is the Torricelli experiment?

In the 17th century, Evangelista Torricelli conducted experiments with mercury that allowed him to measure the presence of air. He would dip a glass tube, closed at one end, into a bowl of mercury and raise the closed end up out of it, keeping the open end submerged.

What did Rene Descartes contribute to the Scientific Revolution?

Analytical Geometry Descartes made the revolutionary discovery that he could solve problems in geometry by converting them into problems in algebra. In La Gèomètrie he showed that curves could be expressed in terms of x and y on a two-dimensional plane and hence as equations in algebra.

How does Bernoulli’s principle apply to everyday life?

One real-life example of Bernoulli’s principle is the dynamic lift created by an airplane wing. The rounded shape of the wing and the slight tilt allows the air to move faster on top of the wing than below it. Therefore, the pressure on top is lower, allowing an upward net force to act on the wing.
