Brownian motion was discovered
by the botanist Robert Brown in 1827, and the theoretical model of Brownian
motion has real-world applications in fields such as mathematics, economics,
physics and biology. It is the presumably random motion of particles suspended
in a liquid or a gas that results from their bombardment by fast-moving atoms
or molecules, but the exact mechanism of Brownian motion still remains one of
the unresolved mysteries in physics. Here circadian and seasonal changes in
long-term macroscopic anisotropic (asymmetric) Brownian motion of a toluidine
blue colloid solution in water in two dimensions were identified, suggesting
that such an anisotropic Brownian motion may be related to an effect of the directional movement of “Universe field”, and thereby providing new
interpretations and potential applications of Brownian motion.
