Build Me a Bridge

A man walking along a California beach was deep in prayer. Suddenly the sky clouded above his head and, in a booming voice, the Lord said, "Because you have TRIED to be faithful to me in all ways, I will grant you one wish."
The man said, "Build a bridge to Hawaii so I can drive over anytime I want."The Lord said, "Your request is very materialistic. Think of the enormous challenges for that kind of undertaking. The supports required to reach the bottom of the Pacific! The concrete and steel it would take! It will nearly exhaust several natural resources. I can do it, but it is hard for me to justify your desire for worldly things. Take a little more time and think of something that would honor and glorify me."
The man thought about it for a long time. Finally he said, "Lord, I wish that I could understand my wife. I want to know how she feels inside, what she's thinking when she gives me the silent treatment, why she cries, what she means when she says ‘nothing's wrong,’ and how I can make a woman truly happy."
The Lord replied, "You want two lanes or four on that bridge?"

Accutron

In 1960, the Accutron 214, the world's first electronic wristwatch by Bulova, was placed on sale in New York City. The original circuit used a germanium PNP transistor circuit with a 360-Hz tuning fork, used for timing accuracy. In 1977 it was replaced by quartz watches. The Accutron has the potential accuracy of better than 2 seconds per day, remarkable in its day of mechanical watches. In 1953, tuning fork watch development began in Switzerland and prototype watches were made in 1955. Its Swiss engineer was Max Hetzel, who moved in 1959 to continue his development of the Bulova Accutron in New York with William Bennett. The CEO of Bulova at the time was Omar Bradley, 5 Star General, US Army, Retired.
