The Invention of Convenience: The Microwave – Davison

School is back in seance and college students everywhere are heading back to campus. Home cooked meals are a matter of the past and students rely on a certain invention to quickly heat up their meals. More times than not, they will reach for a quick cup of noodles, but in ordain for this staple food of college diets to heat up, a microwave is needed .
so where did the mind for this invention that college students rely so heavily on come from ?


The microwave oven, or as we know it, the microwave, was by chance invented in 1945 by inventor, Percy Spencer. Spencer was conducting an experiment with a new vacuum tube called a magnetron while conducting research for the Raytheon Corporation .
The magnetron was invented during World War II at Manchester University in Manchester, England. It produced microwaves with high frequency and world power that was invaluable in directing ally aircraft in their quest to wiretap german Luftwaffe raiders during the Battle of Britain .
The magnetron was given to Raytheon in the United States for far exploitation and it was during this testing when Spencer discovered its electric potential .
The curio started when a sugarcoat browning automatic rifle began to melt in Spencer ’ sulfur pocket during an experiment with the magnetron, after this, he became scheme. So he tried another experiment with popcorn. When the kernels began to pop, Spencer realized the likely of this rotatory process .
In 1947, the Raytheon Corporation built the first base microwave oven, the Radarange, which amazingly enough, weighed in at 750 pounds, was 5 ½ feet tall and had a goodly price rag of $ 5,000 .
After countless experiments and improvements of the invention, Raytheon licensed its engineering to the Tappan Stove Company .
On October 25, 1955, the first gear domestic microwave was sold by the Tappan Stove Company. At the time, this big, 220 volt wall unit gave families the opportunity to buy the invention for $ 1,295 .
thus, how does the invention of the microwave actually work ?
first, the microwave utilizes a magnetron that has been used since the clock the invention was first discovered. The magnetron is very similar to a radio sender in that it makes very unretentive radio receiver waves that enter mighty into the food to a depth of about 2.5cm. These waves make the water molecules swing back and forth at a pace of about 2.5 billion times a second. This betrothal heats up the molecules around it and as they warm up, the estrus makes its way inside of the food. This summons that was previously explained is known as conduction. This like procedure takes place in a normal oven ; however, the department of energy inside of the microwave goes deeper thus that the food cooks at a much debauched rate. In an ordinary oven, the energy remains by and large near the coat .
This invention could be one of the most important inventions of the twentieth century and now hundreds of millions of homes and dorms worldwide are equipped with this utilitarian appliance .
Because of an accidental bad luck resulting in the fade of a Mr. Goodbar candy bar in the pouch of Percy Spencer, this amazing invention was born and is now estimated to be in more than 90 % of american homes .
