Microscopic particles suspended on any fluid has a chaotic behavior since they do not stay at same location. Every moment they experience a number of collisions with fluid molecules from different directions. As a result of these collisions,the particle moves randomly as if it is confused all the time. In physics, this phenomenon is known as Brownian Motion named after the Scottish botanist Robert Brown who first described the phenomenon in 1827. Then, almost 80 years later, in 1905, Albert Einstein published a paper explaining Brownian Motion to establish the idea of existence of atoms and molecules. Now, more than 100 years later, with advancements of computer science, modeling the physical phenomena has become an important task for physicists. Since you are a great programmer and love to solve challenging problems, a group of physicists from your country came to you to help them solve this problem regarding Brownian Motion.
