TECH_RADAR_MINIATURIZATION
Quote #1:
Every time you warm something in an oven, you use a device that helped change the course of history during World War II [...] The cavity magnetron helped scientists and engineers in Great Britain, the US, and other countries to build compact, efficient radar sets that could spot enemy planes, ships, and even submarine periscopes miles away in the dark.

Quote #2:
It was a valve that could spit out pulses of microwave radio energy on a wavelength of 10 cm. This was unheard of. Nothing like it had been invented before. The wavelength for the radar system we were using at the start of the war was one-and-a-half metres. The equipment needed was bulky and the signals indistinct. The cavity magnetron was to be the key that would allow us to develop airborne radar.
