It wasnoticed by a tiny shorts named Brown that, in a solution tiny shorts fine suspended particles, the tiny shorts were in constant movement.Under a powerful microscope these.

They consist themselves of still smaller particles,as we shall see. But the atoms exist all the same, and we may still saythat they are the bricks of which the material universe is built.[Illustration: _Photo: Elliott tiny shorts Fry._SIR tiny shorts RUTHERFORDOne of our most eminent physicists who has succeeded Sir J.
