<font size="3">In 1827, using a microscope, the botanist Robert Brown
observed that pieces of pollen grains suspended in water moved in random
directions. Initially, people thought Brown had discovered the essence of
life. However, after several other experiments, it was apparent that <strong>any</strong>
tiny particles floating in water would move in this way, even microscopic
pieces of dust.<br><br>To the right is a virtual microscope which is
focused on a tiny particle floating in water. When you run that model, you
will see the behavior that Brown observed and what is now known as
Brownian Motion.</font>
