Percy Spencer (July 19, 1894 – September 8, 1970) was an American physicist, electrical engineer and inventor, known as the inventor of the microwave oven. [ 1 ] Early life
Percy Spencer, an engineer working for American defense contractor Raytheon, accidently discovered a new use for radar technology in the mid-1940s. ... The Story Behind the Microwave. AOL.com ...
The true story is that it was invented utterly by accident one fateful day more than 70 years ago, when a Raytheon engineer named Percy Spencer was testing a military-grade magnetron and suddenly ...
A microwave oven or simply microwave is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. [1] This induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating .
In 1945, Raytheon's Percy Spencer invented the microwave oven by discovering that the magnetron could rapidly heat food. In 1947, the company demonstrated the Radarange microwave oven for commercial use.
A microwave oven cooks or heats food by dielectric heating. Cooking food with microwaves was discovered by Percy Spencer on October 8, 1945, while building magnetrons for radar sets at Raytheon. Spencer was working on an active radar set when he noticed a strange sensation, and saw that a peanut candy bar he had in his pocket started to melt.
The microwave oven was invented as an accidental by-product of war-time (World War 2) radar research using magnetrons (vacuum tubes that produce microwave radiation, a type of electromagnetic radiation that has a wavelength between 1 mm and 30 cm). In 1946, the engineer Dr. Percy LeBaron Spencer, who worked for the Raytheon Corporation, was ...
After The Last Olympian, Riordan wanted to put the story of Percy Jackson to rest (for a while, at least), but there were still stories to tell about demigods and their Camp Half-Blood.
