Solution

Robert Brown in 1827 suspended extremely small pollen grains in water. On looking through the microscope, it was found that the pollen grains were moving rapidly throughout water in a very irregular way or zig-zag motion.
Concluding Statement:- This kind of zig-zag movement of particles is called Brownian movement which was named after scientist Robert Brown.
