A mechanic was removing a cylinder head from the motor of a Harley motorcycle when he spotted a well-known heart surgeon in his shop.
The surgeon was there, waiting for the service manager to come and take a look at his bike.
The mechanic shouted across the garage, "Hey, Doc, can I ask you a question?"
The surgeon a bit surprised, walked over to the mechanic working on the motorcycle.

The mechanic straightened up, wiped his hands on a rag and asked, "So Doc, look at this engine. I open its heart, take the valves out, fix 'em, put 'em back in, and when I finish, it works just like new. So how come I get such a small salary and you get the really big bucks, when you and I are doing basically the same work?"
The surgeon paused, smiled and leaned over, and whispered to the mechanic, "Try doing it with the engine running."

### Oskar Morgenstern

Died 26 Jul 1977 at age 75 (born 24 Jan 1902).German-American economist and mathematician who popularized “game theory” which mathematically analyzes behaviour of man or animals in terms of strategies to maximize gains and minimize losses. He coauthored Theory of Games and Economic Behavior (1944), with John von Neumann, which extended Neumann's 1928 theory of games of strategy to competitive business situations. They suggested that often in a business situation (“game”), the outcome depends on several parties (“players”), each estimating what all of the others will do before determining their own strategy. Morgenstern was a professor at Vienna University, Austria, from 1931 until the Nazi occupation in 1938), when he fled to America and joined the faculty at Princeton University. His later publications included works on economic prediction and aspects of U.S. defence.«
