Zitat des Tages über Theoreme / Theorems:
To a person of analytical ability, perceptive enough to realise that mathematical equipment was a powerful sword in economics, the world of economics was his or her oyster in 1935. The terrain was strewn with beautiful theorems begging to be picked up and arranged in unified order.
There are three signs of senility. The first sign is that a man forgets his theorems. The second sign is that he forgets to zip up. The third sign is that he forgets to zip down.
A mathematician is a device for turning coffee into theorems.
Economists often like startling theorems, results which seem to run counter to conventional wisdom.
The pursuit of pretty formulas and neat theorems can no doubt quickly degenerate into a silly vice, but so can the quest for austere generalities which are so very general indeed that they are incapable of application to any particular.
I have found a very great number of exceedingly beautiful theorems.
Math does come easily to me, but I was always much more interested in what theorems imply about the world than in proving them.
Young men should prove theorems, old men should write books.
