Robert Brown was a scientist and his major field was botany but he is also known for his contribution in physics for developing a concept called the Brownian motion. He also started a huge effort in Australia where he collected3400 botanical samples belonging to different species and almost 2000 of these species were previously unknown. He published his finding in a book called “Prodromus Florae Novae Hollandiae et Insulae Van Diemen”. Later on he became the in charge of the botanical collection at the British museum. He was the first one to name the central body in the cell as the nucleus. He also concluded that particles move in a haphazard manner after observing the motion of pollen and dust particles, his theory cam to be known as the “Brownian Motion’
