Which kitchen appliance was invented by Percy Spencer in 1945?
"sensation that continues to this day. 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. Although he was not the first to notice this phenomenon, as the holder of 120 patents, Spencer was no stranger to discovery and experiment, and realized what was happening. The radar had melted his"
"Spencer's microwave was popcorn, and the second was an egg, which exploded in the face of one of the experimenters. To verify his finding, Spencer created a high density electromagnetic field by feeding microwave power from a magnetron into a metal box from which it had no way to escape. When food was placed in the box with the microwave energy, the temperature of the food rose rapidly. On 8 October 1945, Raytheon filed a United States patent application for Spencer's microwave cooking process, and an oven that heated food using microwave energy from a magnetron was soon placed in"
"production of electromagnetic waves of a small enough wavelength (microwaves). American engineer Percy Spencer is generally credited with inventing the modern microwave oven after World War II from radar technology developed during the war. Named the ""Radarange"", it was first sold in 1946. 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. Sharp Corporation introduced the first microwave oven with a turntable between 1964 and 1966. The countertop microwave oven was first introduced in 1967 by the Amana"
"microwave cooking oven, eventually named the Radarange. In 1947, the first commercially produced microwave oven was about 6 feet tall, weighed about 750 lbs, and cost about 5,000 US$. In 1967 the first relatively affordable ($495) and reasonably sized (counter-top) microwave oven was available for sale. Spencer became Senior Vice President and a Senior Member of the Board of Directors at Raytheon. He received 300 patents during his career, and a building at the Raytheon Missile Defense Center in Burlington, Massachusetts is named in his honor. Other achievements and awards, besides the Distinguished Public Service Award, included a membership of"

Contracts were awarded to Raytheon and other companies for mass production of the magnetron. In 1945, the specific heating effect of a high-power microwave beam was accidentally discovered by Percy Spencer, an American self-taught engineer from Howland, Maine. Employed by Raytheon at the time, he noticed that microwaves from an active radar set he was working on started to melt a chocolate bar he had in his pocket. The first food deliberately cooked with"

The first electric ovens were invented in the very late 19th century, however, like many electrical inventions destined for commercial use, mass ownership of electrical ovens could not be a reality until better and more efficient use of electricity was available. More recently, ovens have become slightly more high-tech in terms of cooking strategy. The microwave as a cooking tool was discovered by Percy Spencer in 1946, and with the help from engineers, the microwave oven was patented. The microwave oven uses microwave radiation to excite the molecules"

The biscuits proved more popular than the machines, so Perky moved East and opened his first bakery in Boston, Massachusetts and then in Worcester, Massachusetts in 1895, retaining the name of The Cereal Machine Company, and adding the name of the Shredded Wheat Company. Whether he developed his ideas on nutrition before the machine or after, Perky was a food faddist who believed the fundamental issue was how to nourish a man so that his condition will be natural.

"Serendipity Serendipity means an unplanned, fortunate discovery. The notion of serendipity is a common occurrence throughout the history of scientific innovation. Examples are Alexander Fleming's accidental discovery of penicillin in 1928, the invention of the microwave oven by Percy Spencer in 1945, and the invention of the Post-it note by Spencer Silver in 1968. In June 2004, a British translation company voted the word to be one of the ten English words hardest to translate. However, due to its sociological use, the word has since been exported into many other languages. The first noted use of ""serendipity"" in the English"

"attached to opposite ends. To cook the rice, the box was filled with washed rice and water, and then a current was applied. This caused the water to boil. When the rice was cooked, the reduction of the water quantity caused an increase in resistance which reduced the power to a stay-warm state. This method, however, was not suitable for different water qualities or degrees of rice washing and as such varied the amount of heat produced and the end results. It also presented a high risk of electrocution, thus it was not suitable for home cooking. In 1945, the"

However, many of these utensils were expensive and not affordable by the majority of householders. Some people considered them unnecessary, too. James Frank Breazeale decried the explosion in patented ""labour-saving"" devices for the modern kitchen—promoted in exhibitions and advertised in ""Household Guides"" at the start of the 20th century—, saying that ""the best way for the housewife to peel a potato, for example, is in the old-fashioned way, with a knife, and not with a patented potato peeler""."
