Artist unknown Robert Brown was one of the greatest botanists of all time. In 1801 he joined an exciting expedition to sail around Australia on HMS Investigator. During the expedition he collected thousands of plant specimens many of which were new to European naturalists. He also made a major contribution to science through his
use of the microscope. He noticed that when looking at magnified
pollen grains in liquid, they would appear to move randomly
in a zigzag fashion. Known as Brownian motion this
observation was an important development in the history of
physics. |
