Doctor visit
A man and his wife were making their first doctor visit prior to the birth of their first child. After everything checked out, the doctor took a small stamp and stamped the wife's stomach with indelible ink.
The couple was curious about what the stamp was for, so when they got home, he dug out his magnifying glass to try to see what it was. In very tiny letters, the stamp said, "When you can read this, come back and see me."

Donald A. GlaserDied 28 Feb 2013 at age 86 (born 21 Sep 1926).Donald Arthur Glaser was an American physicist who was awarded the Nobel Prize for Physics in 1960 for his invention of the bubble chamber in which the behaviour of subatomic particles can be observed by the tracks they leave. A flash photograph records the particle's path. Glaser's chamber contains a superheated liquid maintained in a superheated, unstable state without boiling. A piston causing a rapid decrease in pressure creates a tendency to boil at the slightest disturbance in the liquid. Then any atomic particle passing through the chamber leaves a track of small gas bubbles caused by an instantaneous boiling along its path where the ions it creates act as bubble-development centers.« |
