Minor Thoughts from me to you

What a great story, from Popular Mechanics.

The microwave is beloved for its speed and ease of use. But what you might not know about your indispensable kitchen appliance is that it was invented utterly by accident one fateful day 70 years ago, when a Raytheon engineer named Percy Spencer was testing a military-grade magnetron and suddenly realized his snack had melted.

​> …

Spencer earned several patents while working on more efficient and effective ways to mass-produce radar magnetrons. A radar magnetron is a sort of electric whistle that instead of creating vibrating sound creates vibrating electromagnetic waves. According to Michalak, at the time Spencer was trying to improve the power level of the magnetron tubes to be used in radar sets. On that fateful day in 1946, Spencer was testing one of his magnetrons when he stuck his hand in his pocket, preparing for the lunch break, when he made a shocking discovery: The peanut cluster bar had melted. Says Spencer, "It was a gooey, sticky mess."

…

​> Understandably curious just what the heck had happened, Spencer ran another test with the magnetron. This time he put an egg underneath the tube. Moments later, it exploded, covering his face in egg. "I always thought that this was the origin of the expression 'egg in your face'," Rod Spencer laughs. The following day, Percy Spencer brought in corn kernels, popped them with his new invention, and shared some popcorn with the entire office. The microwave oven was born.
