The story of the word

A Greek prefix bolted onto a plain English noun, with the radiation sense arriving first in the 1930s: small only by comparison with the metre-long radio waves already in use. The cooking application came out of wartime radar work, when Percy Spencer at Raytheon noticed a chocolate bar melting in his pocket beside a running magnetron. The first commercial oven weighed about 340 kg and stood taller than the cook.
