You‘re a mathematician

Israel Gelfand

“People think they don‘t understand math, but it‘s all about how you explain it to them. If you ask a drunkard what number is larger, 2/3 or 3/5 , he won‘t be able to tell you. But if you rephrase the question: what is better, 2 bottles of vodka for 3 people or 3 bottles of vodka for 5 people, he will tell you right away: 2 bottles for 3 people, of course.”

Israel Gelfand, Soviet mathematician. (1913-2009)

First capital

Books constitute capital. A library book lasts as long as a house, for hundreds of years. It is not then an article of mere consumption, but fairly of capital, and often in the case of professional men, setting out in life, it is their only capital.
