Q1: Feynman’s Question:
If in some cataclysm, all of scientific knowledge were to be destroyed, and only one sentence passed on to the next generation of creatures, what statement would contain the most information in the fewest words?The Feynman Lectures on
Physics, Vol. 1, Chapter 1, Section 1.2

Feynman’s answer:
Matter is made of atoms
“In that one sentence, you will see, there is an enormous amount of information about the world, if just a little imagination and thinking is applied.”
