A married couple went to the hospital together to have their baby delivered.
Upon their arrival, the doctor said he had invented a new machine that would transfer a portion of the mother's labor pain to the father of the baby. He asked if they were willing to try it out. They were both very much in favor of it.
The doctor set the knob to 10 percent for starters, explaining that even 10 percent was probably more pain than the father had ever experienced before. But as the labor progressed, the husband felt fine, so he asked the doctor to go ahead and bump it up a notch. The doctor then adjusted the machine to 20 percent pain transfer. The husband was still feeling fine.
The doctor checked the husband's blood pressure and pulse and was amazed at how well he was doing. At this, they decided to try for 50 percent.
The husband continued to feel quite well. Since it was obviously helping out his wife considerably, he encouraged the doctor to transfer ALL the pain to him.
The wife delivered a healthy baby with virtually no pain. She and her husband were ecstatic. When they got home, the mailman was dead on their porch.

Benoit ClapeyronBorn 26 Feb 1799; died 28 Jan 1864 at age 64.French engineer who expressed Sadi Carnot's ideas on heat analytically, with the help of graphical representations. While investigating the operation of steam engines, Clapeyron found there was a relationship (1834) between the heat of vaporization of a fluid, its temperature and the increase in its volume upon vaporization. Made more general by Clausius, it is now known as the Clausius-Clapeyron formula. It provided the basis of the second law of thermodynamics. In engineering, Clayeyron designed and built locomotives and metal bridges. He also served on a committee investigating the construction of the Suez Canal and on a committee which considered how steam engines could be used in the navy. |
