“Today let us look into a microscope and consider Brownian Motion, which is the random motion of particles suspended in a fluid that can be observed through a microscope.
When this was first described by Robert Brown in 1827 when looking at pollen suspended in a solution. At that time atoms and molecules was just a wild theory and the movements he observed seemed random and unpredictable. It was not until 1905 when Albert Einstein came up with a comprehensive theory that the reason was collision from the invisible molecules in the fluid, and that the movement could be explained (if not predicted). Therefore it constituted one of the first concrete evidences of the building.blocks of matter.”
“Think about concepts like apparent randomness, of motion and of what we cannot see. Maybe you can imagine being puppeteered like pollen in a fluid, or just dance to randomness and see where you end up.”
Rising from bottom,
bubbles float, dance
and skip in golden circles.
Some are tiny, others
large as they effervesce
in a foam–like finish
at the top of a champagne glass,
and then, vanish.
