Question

What did Robert brown discovered? ​

Answer 1

Answer:

Brownian Motion

In 1827, the Scottish botanist Robert Brown looked through a microscope at pollen grains suspended in water, and discovered what we now call Brownian Motion. It was an unintentional discovery. He was not looking for the effect that now bears his name, but was, rather, curious about reproduction.

Answer 2

• Brownian motion, also known as pedesis, is the random movement of particles in a medium (a liquid or a gas).
• Random fluctuations in a particle's position within a fluid sub-domain are frequently followed by a migration to another sub-domain in this pattern of motion.
• Following each move, the new closed volume experiences additional swings.
• This pattern depicts a fluid in thermal equilibrium at a certain temperature.
• There is no preferred direction of flow inside such a fluid (as in transport phenomena).
• The fluid's total linear and angular momenta, to be more explicit, stay null across time.
• The caloric component of a fluid's internal energy is calculated by adding the kinetic energies of molecular Brownian movements, rotations, and vibrations (the Equipartition theorem).
