In existographies, Gustave Coriolis (1833-112 BE) (1772-1843 ACM) (IQ:180|#155) (ID:3.53|51) (PR:3,372|65AE / physicist:75) (SIG:9) (CR:35) (LH:6) (TL:46) was a French physicist, noted for []

Overview

In 1829, Coriolis, in his Calculation of the Effect of Machines, introduced, via what he called the "work transmission principle", the formula for work as force times distance; namely:[1]

where F is force and d is the distance of space through which the body is moved, and W is the work done. The original derivation of this, to note is in French, done using Cartesian coordinates, a work yet to be translated into English.

Kinetic energy

Coriolis, according to some assertions, was the one who introduced the factor ½ in Leibniz’s 1686 vis viva for the sake of mathematical convenience (others say it was Lagrange who did this in 1811).

Coriolis effect

In 1835, Coriolis, in his “On the Equations of Motion of a System of Bodies”, introduced the Coriolis effect, namely:

“Any particle moving in the northern hemisphere is deflected to the right; and to his left in the southern hemisphere.”
— Gustave Coriolis (1835), “On the Equations of Motion of a System of Bodies” [2]

according to which explains why toilets drain (and people move) clockwise in the northern hemisphere (drive on right side of road) and counterclockwise (drive on left side of road) in the southern hemisphere
