Marriage Counseling

A husband and wife came for counselling after 25 years of marriage. When asked what the problem was, the wife went into an angry tirade listing each and every problem they had ever had in the 25 years they had been married.
She went on and on: neglect, lack of intimacy, emptiness, loneliness, feeling unloved and unloveable, a long list of unmet needs she had endured over the course of their quarter century of marriage.
Finally, after allowing this to go on for a sufficient length of time, the therapist stood up, walked around his desk and, asking the wife to stand, embraced her and kissed her passionately on the mouth.
The woman shut up and, in a daze, quietly sat down;. The therapist turned to the husband and said, "This is what your wife needs at least seven times a week. Do you think you can do this?"
The husband thought for a moment and replied, "Well, Doc, I can drop her off here on Mondays and Wednesdays, but on the other days I play golf."

Donald A. Glaser

Born 21 Sep 1926; died 28 Feb 2013 at age 86.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.«
