[3] His name is commemorated in the Bernoulli's principle, a particular example of the conservation of energy, which describes the mathematics of the mechanism underlying the operation of two important technologies of the 20th century: the carburetor and the aeroplane wing.

[8] When he was in school, Johann encouraged Daniel to study business citing poor financial compensation for mathematicians.

[8] Daniel studied medicine at Basel, Heidelberg, and Strasbourg, and earned a PhD in anatomy and botany in 1721.

A temporary illness[8] together with the censorship by the Russian Orthodox Church[11] and disagreements over his salary gave him an excuse for leaving St. Petersburg in 1733.

[12] He returned to the University of Basel, where he successively held the chairs of medicine, metaphysics, and natural philosophy until his death.

It resembles Joseph Louis Lagrange's Mécanique Analytique in being arranged so that all the results are consequences of a single principle, namely, conservation of energy.

Bernoulli also wrote a large number of papers on various mechanical questions, especially on problems connected with vibrating strings, and the solutions given by Brook Taylor and by Jean le Rond d'Alembert.

[18] In Hydrodynamica (1738) he laid the basis for the kinetic theory of gases, and applied the idea to explain Boyle's law.
