21. On long timescales, the mathematical Brownian motion is well described by a Langevin equation. 22. You seem to think that your rigid material would be immune to Brownian motion . 23. In the Black Scholes model, prices are assumed to follow the geometric Brownian motion . 24. The first concept to understand for anisotropy measurements is the concept of Brownian motion . 25. Fractional Brownian motion is the only self-similar Gaussian process. 26. Regarding the question of the Brownian motion , that is well beyond my knowledge of physics. 27. Brownian motion deflects the bead from the resting position.28. Thermal noise ( e . g ., Brownian motion ) is another limit to sensitivity. 29. It is related to brownian motion and gaussian distributions. 30. ;1905 : Albert Einstein explains Brownian motion in a way that definitively proves atomic theory.
