Stop slandering this amazing device with your modern dismissive sensibilities!

The exploitation of high-frequency radio waves for heating substances was made possible by the development of vacuum tube radio transmitters around 1920. By 1930 the application of short waves to heat human tissue had developed into the medical therapy of diathermy. At the 1933 Chicago World's Fair, Westinghouse demonstrated the cooking of foods between two metal plates attached to a 10 kW, 60 MHz shortwave transmitter.[3] The Westinghouse team, led by I. F. Mouromtseff, found that foods like steaks and potatoes could be cooked in minutes.
 
The 1937 United States patent application by Bell Laboratories states:[4]
 
This invention relates to heating systems for dielectric materials and the object of the invention is to heat such materials uniformly and substantially simultaneously throughout their mass. ... It has been proposed therefore to heat such materials simultaneously throughout their mass by means of the dielectric loss produced in them when they are subjected to a high voltage, high frequency field.
 
However, lower-frequency dielectric heating, as described in the aforementioned patent, is (like induction heating) an electromagnetic heating effect, the result of the so-called near-field effects that exist in an electromagnetic cavity that is small compared with the wavelength of the electromagnetic field. This patent proposed radio frequency heating, at 10 to 20 megahertz (wavelength 15 to 30 meters).[5] Heating from microwaves that have a wavelength that is small relative to the cavity (as in a modern microwave oven) is due to "far-field" effects that are due to classical electromagnetic radiation that describes freely propagating light and microwaves suitably far from their source. Nevertheless, the primary heating effect of all types of electromagnetic fields at both radio and microwave frequencies occurs via the dielectric heating effect, as polarized molecules are affected by a rapidly alternating electric field.
 
The invention of the cavity magnetron made possible the production of electromagnetic waves of a small enough wavelength (microwaves). The magnetron was originally a crucial component in the development of short wavelength radar during World War II.[6] In 1937–1940, a multi-cavity magnetron was built by the British physicist Sir John Turton Randall, FRSE, together with a team of British coworkers, for the British and American military radar installations in World War II.[7] A more high-powered microwave generator that worked at shorter wavelengths was needed, and in 1940, at the University of Birmingham in England, Randall and Harry Boot produced a working prototype.[8] They invented a valve that could spit out pulses of microwave radio energy on a wavelength of 10 cm, an unprecedented discovery.[7]
 
Sir Henry Tizard travelled to the U.S. in late September 1940 to offer the magnetron in exchange for their financial and industrial help (see Tizard Mission).[7] An early 6 kW version, built in England by the General Electric Company Research Laboratories, Wembley, London, was given to the U.S. government in September 1940. The magnetron was later described by American historian James Phinney Baxter III as "[t]he most valuable cargo ever brought to our shores".[9] Contracts were awarded to Raytheon and other companies for mass production of the magnetron.
 
Discovery
 
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 Spencer's microwave was popcorn, and the second was an egg, which exploded in the face of one of the experimenters.[10][11] 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 a Boston restaurant for testing.[12]

The Microwave Oven is an amazing scientific achievement that deserves some appreciation!

If you're making cups of tea with microwave please ban your account

 

I think toilets are great inventions but I still wouldn't drink the water from there :imstupid:

lmao I drink coffee hurrplz.png but as most normal people I have a stove, a microwave, a refrigerator and even a dishwasherahmagahplz.png

 

Each has a use and there are things that a microwave is superior at heating quickly and there are many things that taste better cooked on the stovetop or grilled etc. But to assume that all Americans do that because they have microwaves is kinda silly dont you think?  I personally dont know anyone who would prefer heating water in the microwave unless they had no time.laugh.png  But narratives are stronglaugh.png

 

Also comparing a toilet to a microwave is moronic don't you think? lmaaaao. Do you not understand how it works?

My friend once told me she cooks bacon in a microwave.

SLHJKDFGJKGFKHJLGH I FUCKING WHEEZED

 

Goes to microwave a good 'ol cup of tea tbh

 

we love our convenient electronic box

Microwaves should ONLY be used for reheating leftovers like

 

 

 

 

Never to actually COOK something]

 

 

 

 

Also it isn't moronic at all tbh

 

 

 

Both get filled with shit ahmagahplz.png

Nobody cooks with microwaves

The microwave dinners I assume you’re talking about are already cooked and then frozen

We ARE reheating lol

I know what they are I'm not dumb

 

 

 

 

But there are literally people saying they know other people who DO cook with them

 

 

 

 

And like I said, ready meals are still shit lmaoo
