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.

Arthur Holmes

Died 20 Sep 1965 at age 75 (born 14 Jan 1890).English geologist and petrologist was one of the foremost geologists of the twentieth century, who made major contributions to the geochronology of Africa, the genesis of igneous rocks, and physical geology. He developed a method of determining the age of the earth based on measurement of uranium decay in igneous rocks (which invalidated William Thomson Kelvin's hypothesis that the earth's age can be established on the basis of the planet's cooling from a initial molten state). Holmes' method proved to be remarkably accurate and laid the foundation of isotope geology. This was the first quantitative time scale for geology based on measuring the radioactive constituents of rocks.
