ATOMS AND MOLECULES IN THINKING
« If, as a result of a global catastrophe, all the accumulated scientific knowledge would have been destroyed and only one phrase would have passed to future generations of living beings, what statement made up of the smallest number of words would bring the greatest information? I believe that this is an atomic hypothesis ... all bodies are composed of atoms - small bodies that are in continuous motion, attracted at a short distance, but repel if one of them is more tightly pressed to the other. In this phrase alone there is an incredible amount of information about the world, all you have to do is attach a little imagination and a little thought to it». R. Feynman
