Undercover Clergy

A minister, a priest and a rabbi went for a hike one day. It was very hot. They were sweating and exhausted when they came upon a small lake. Since it was fairly secluded, they took off all their clothes and jumped in the water.
Feeling refreshed, the trio decided to pick a few berries while enjoying their "freedom." As they were crossing an open area, who should come along but a group of ladies from town. Unable to get to their clothes in time, the minister and the priest covered their privates and the rabbi covered his face while they ran for cover.After the ladies had left and the men got their clothes back on, the minister and the priest asked the rabbi why he covered his face rather than his privates. The rabbi replied, "I don't know about you, but in MY congregation, it's my face they would recognize."

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.
