He found that the entire material universe was composed of particles or “indivisible units”. These units exhibit in endless variation the basic qualities of matter: mass, cohesion, temperature, and movement. They combine to form structures which seem to have some permanence. But actually these are all composed of miniscule _kalapas_ which are in a state of continuously arising and passing away. This is the ultimate reality of matter: a constant stream of waves or particles. This is the body which we each call “myself”
And this scientist was: Buddha.
