A Golfer's Deal With the Devil

A golfer was having a tough day and in his frustration he blurted out, "I would give anything for a birdie on this hole." A nearby stranger walked out of the woods beside the hole and whispered, "If you give up one quarter of your sex life, I guarantee you will make this shot."The golfer said "OK." He made the shot for birdie.A few holes later, he was having trouble on another hole. "Please, let me make this for eagle" he said.Again, the stranger stepped up to him and said, "If you give up another quarter of your sex life, you will make eagle.""You're on," the golfer said, and made the shot for eagle.On the eighteenth hole, the golfer needed an eagle to win. The stranger again stepped up and said "If you give up the last half of your sex life, you will make eagle to win.""OK," the golfer said, and made his shot for eagle, winning the round.As he was walking back to the clubhouse, the stranger walked up beside him and said, "I think I should inform you that I am the Devil, and from now on you will have no sex life."The golfer turned to him, smiled, and said, "Nice to meet you, my name is Father O'Malley!"

Crystal rectifier

In 1874, a paper by Ferdinand Braun (1850-1918) was published in the Annalen der Physik und Chemie describing his discovery of the electrical rectifier effect. He observed that certain crystals of metal sulphides have a larger or smaller resistance to an electric current, depending on its direction of flow. He used a galena crystal, a semiconductor material composed of lead sulfide. He found the rectifying effect especially true if at least one of the electrodes was a pointed wire. Thus, he had discovered the point-contact rectifier effect, the first semiconductor device. This effect wasn't used until over 30 years later in the form of the “cat's whisker”crystal radio detector which ultimately led to the point-contact transistor first produced in 1948.
