Pray Before Eating

Everyone was seated around the table as the food was being served. When little Logan received his plate, he started eating right away.
"Logan, wait until we say our prayer," his mother reminded him.
"I don't have to," the little boy replied.
"Of course you do," his mother insisted, "we say a prayer before eating at our house."
"That's at our house," Logan explained, "but this is Grandma's house and she knows how to cook."

Transistor hearing aid

In 1952, the first transistor hearing aid went on sale, the model 1010 manufactured by the Sonotone Corporation in Elmsford, NY, U.S. It weighed 3.5-oz, measured 3"x1.5"x0.6" and cost $229.50 (about $1500.00 today). It was a hybrid device consisting of two sub miniature pre-amplifier tubes and a single transistor as the final audio amplifier to benefit from the low power consumption of transistors. The reason for the hybrid design was that the first junction transistors had signal to noise ratios which were inferior to tubes. Within months, transistor production techniques were improved largely eliminating noise, so the hybrid model was shortly discontinued.
