“Of all the frictional resistances, the one that most retards human movement is ignorance, what Buddha called ‘the greatest evil in the world.’ The friction which results from ignorance … can be reduced only by the spread of knowledge and the unification of the heterogeneous elements of humanity. No effort could be better spent.”

Nikola Tesla

“If I could explain it to the average person, I wouldn’t have been worth the Nobel Prize.”

Richard P. Feynman
