Brownian motion

While working on a fine morning in 1827, little did a botanist named Robert Brown know that what he was about to witness through his microscope would eventually lead to the discovery of the existence of invisible matter.

Rutherford disproved Thomson's theory of the atom in 1911. He later described this as ‘quite the most incredible event that has ever happened to me in my life.'

Brownian movement

Brownian Motion: The random movement of particles in a colloid caused by collisions between the particles.

Robert Brown, botanist, mostly known for Brownian Motion, applied in a wide range of disciplines involving stochastic processes, popular use in physics and finance.

What is the difference between Catalytic Cracking and Catalytic Reforming? Catalytic cracking mainly gives small alkanes and alkenes; Catalytic reforming ..

Brownian motion is the constant and random movement of microscopic particles (for example, a speck of dust) in a liquid or gas. Due to the impact of atoms and molecules, these small bodies seen under a microscope move. The yellow circle represents a microscopic body, while the purple circles represent atoms that crash into the microscopic particle.

Brownian movement of a particle of gamboge in water. The points indicate the successive positions of the particle over 30-second intervals. The observations were performed by J. Perrin under a microscope at a magnification of approximately 3,000.
