Geertruida de Haas-Lorentz
Encyclopedia
Geertruida Luberta de Haas-Lorentz (20 November 1885, Leiden–1973) was a female Dutch
physicist
and the first to perform fluctuational analysis of electrons as Brownian
particles. Consequently she is considered to be the first female in electrical noise
theory. She was the eldest daughter of the physicist H. A. Lorentz
and Aletta Catharina Kaiser. In 1910, she married the physicist W.J. de Haas
and they had two sons and two daughters.
Geertruida Lorentz studied physics at the University of Leiden under her father, and earned her doctor's degree in 1912 on a thesis entitled "Over de theorie van de Brown'schen beweging en daarmede verwante verschijnselen" (On the theory of Brownian motion
and related phenomena).

Physicist
A physicist is a scientist who studies or practices physics. Physicists study a wide range of physical phenomena in many branches of physics spanning all length scales: from sub-atomic particles of which all ordinary matter is made to the behavior of the material Universe as a whole...

Brownian motion or pedesis is the presumably random drifting of particles suspended in a fluid or the mathematical model used to describe such random movements, which is often called a particle theory.The mathematical model of Brownian motion has several real-world applications...
