“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

“Two things are infinite: the universe and human stupidity; and I’m not sure about the universe.”

Albert Einstein
