Yes, we know that videos of people microwaving compact discs have been around since YouTube went live, but a professional photographer decided to capture this process with an expensive DSLR camera – possibly the Canon EOS-1D X – for all to see. Let’s just say that things do get a bit toasty. Continue reading to see why.
A microwave basically heats food by bombarding it with electromagnetic radiation in the microwave spectrum causing polarized molecules in the food to rotate and build up thermal energy in a process known as dielectric heating. Microwave ovens heat foods quickly and efficiently because excitation is fairly uniform in the outer 25-38 mm of a dense (high water content) food item; food is more evenly heated throughout (except in thick, dense objects) than generally occurs in other cooking techniques.
Percy Spencer invented the first microwave oven after World War II from radar technology developed during the war. Named the “Radarange”, it was first sold in 1947. Raytheon later licensed its patents for a home-use microwave oven that was first introduced by Tappan in 1955, but these units were still too large and expensive for general home use. The countertop microwave oven was first introduced in 1967 by the Amana Corporation, which was acquired in 1965 by Raytheon.
