While on a road trip, an elder...

While on a road trip, an elderly couple stopped at a roadside restaurant for lunch. After finishing their meal, they left the restaurant and resumed their trip. When leaving, the elderly woman unknowingly left her glasses on the table. And, she didn't miss them until after they had been driving about twenty minutes. By then, to add to the aggravation, they had to travel quite a distance before they could find a place to turn around in order to return to the restaurant to retrieve her glasses.
All the way back, the elderly husband became the classic grouchy old man. He fussed and complained and scolded his wife relentlessly during the entire return drive. The more he chided her, the more agitated he became. He just wouldn't let up one minute.
To her relief, they finally arrived at the restaurant. And as the woman got out of the car and hurried inside to retrieve her glasses, the old geezer yelled to her, "While you're in there, you might as well get my hat".

Spectrophotometer

In 1935, the first U.S. patent for a spectrophotometer was issued to Professor Arthur Cobb Hardy of Wellesley, Mass. (No. 1,987,441) which he called a “photometric apparatus.”It could detect two million different shades of colour and make a permanent record chart of the results. The patent was assigned to the General Electric Company of Schenectady, N.Y. which sold the first machine on 24 May 1935. It used a photo-electric device to receive light alternately from a sample and from a standard for comparison. It eliminated any need for the two beams (from sample and from standard) to travel different optical paths which in previous designs could introduce inaccuracies if one path varied from the other.«[Image: a "GE-Hardy" double-beam recording spectrophotometer photographed in 1938 showing Walt Disney with the instrument at his studios.]
