This seems to have been because of the Wed get smaller and smaller all the way to infinity, and thered be no end point. the new organism. He asserted, for example, that sensations are changes produced in the soul by atoms emitted from other objects that impinge on it; the atoms of the soul can be affected only by the contact of other atoms. This process is called nuclear fission. Democritus (460-370 BC), a Greek philosopher, was the first person to use the word atom or atomos (in Greek), which means indivisible or unbreakable, to describe the smallest particle of any substance.

However, there were some philosophers who believed that there was a limit to how small a grain of sand could be divided. Protons and neutrons are made of even smaller particles called quarks. Our minds create reality out of these atoms, and everything is just an illusion we play on ourselves. Were all just marbles, bouncing around to the laws of physics. the letters of the alphabet, which can produce a multitude of They can take on an infinite variety of shapes: there are Most proteins are about 10 nanometers wide, and a typical virus is about 100 nanometers wide.
