The Florist

A new business was opening and one of the owner's friends wanted to send him flowers for the occasion. They arrived at the new business site and the owner read the card, which said: 'Rest in Peace.'
The owner was angry and called the florist to complain. After he had told the florist of the obvious mistake and how angry he was, the florist replied:
'Sir, I'm really sorry for the mistake, but rather than getting angry, you should imagine this - somewhere, there is a funeral taking place today, and they have flowers with a note saying: 'Congratulations on your new location!''

Phototransistor

In 1950, the invention of the phototransistor was announced. This was a transistor operated by light rather than electric current, invented by Dr. John Northrup Shive of the Bell Telephone Laboratories at Murray Hill, N.J. It used a tiny chip of germanium, a semiconductor material, but only a single collector wire. The tip of this wire rests in a small dimple ground into one side of the germanium disk. At this point the germanium disk is only three thousandths of an inch thick. Light focussed on the opposite, un-dimpled side of the disk can control the flow of current in the wire, thus making a control device similar in function to a photo-electric cell.
