| He is mostly remembered for his claims of mathematics to mechanics, especially fluid mechanics, and for his ground-breaking work in probability and statistics. |
| Bernoulli's name is celebrated in the Bernoulli principle, a specific example of the conservation of energy, which describes the mathematics of the mechanism basic the operation of two important technologies used in the 20th century: the carburetor and the airplane wing. |
| His earliest mathematical work was the Exercitationes or mathematical exercises which were published in 1724 with the help of Goldbach. |
| Two years later he pointed out for the first time the recurrent appeal of resolving a compound motion into motions of translation and a motion of rotation. |
| His chief work is Hydrodynamica, which he published in 1738; it resembles Joseph Louis Lagrange's Mécanique Analytique because it was arranged so that all the results are consequences of a single principle, mostly the conservation of energy. |
| This was trailed by a memoir on the theory of the tides, to which, resembled the memoirs by Euler and Colin Maclaurin. |
| Bernoulli and Euler tried to discover more about the flow of fluids. |
| They mostly wanted to know about the relationship between the speed at which blood flows and its pressure. |
| To explore this, Daniel experimented by puncturing the wall of a pipe with a small open ended straw and noticed that the height to which the fluid rose up the straw was related to fluid's pressure in the pipe. |
| Physicians all over Europe were soon measuring patients' blood pressure by sticking point-ended glass tubes directly into their veins. |
| It was not until almost 170 years later in 1896 that an Italian doctor discovered a less painful method which is still used today. |
| Bernoulli's method of gaging pressure is still used today in modern aircraft to measure the speed of the air passing the plane; that is its air speed. |
| To take his discoveries further, Daniel Bernoulli returned to his earlier work on Conservation of Energy. |
| It was known that a moving body exchanges its kinetic energy for potential energy when it increases height. Bernoulli realized in a similar way that a moving fluid exchanges its kinetic energy for pressure. |
| Mathematically this law is now written: |
| 1/2pu2+P=constant |
