Where did Dr Percy Spencer invent the microwave?
Raytheon Corporation, where he was actually trying to invent some kind of appliance for the war.
Where was the first microwave built?
The first microwave oven was built in the United States by Percy Spencer, an engineer at Raytheon, in the early 1940s. Spencer discovered the cooking properties of microwave radiation while working on radar technology during World War II. The prototype he created in 1945, known as the "Radarange," was the first commercial microwave oven. It revolutionized cooking and heating food, leading to the development of the microwave ovens we use today.
What inventions came by way of something unintended?
Many notable inventions emerged from unintended discoveries, such as the microwave oven, which was created when Percy Spencer noticed a chocolate bar melting in his pocket while working with radar technology. Similarly, penicillin was discovered by Alexander Fleming when he observed that mold had contaminated his bacterial cultures and killed the surrounding bacteria. Another example is the Post-it Note, which originated from an unsuccessful attempt to create a super-strong adhesive, leading to the development of a low-tack, reusable adhesive instead. These inventions highlight how serendipity can lead to significant advancements.
What invention came about by mistake?
Several inventions have been found by mistake. The microwave is one of them. Percy LeBaron Spencer was working as an engineer with the Raytheon company when he was experimenting with and testing a magnetron. The magnetron was invented during WWII and allowed the Allies to pinpoint the exact locations of Nazi war machines and arsenals, as the magnetron produced microwaves which radar then bounced off the arsenals, and back to the Allies. Whilst testing the magnetron after the war, Dr Spencer reached into his pocket for his chocolate bar, and discovered it had completely melted. He made the connection between the melted chocolate and the heat-producing magnetron, and tested his theory on a bag of unpopped corn kernels, which then popped. Next, he placed an egg in front of the magnetron. The egg exploded. Dr Spencer is therefore credited with discovering one of the critical components of the microwave oven. Charles Goodyear, a businessman who experimented with the properties of gum elastic, accidentally discovered the process of vulcanisation of rubber when he dropped some rubber mixed with sulfur on a hot stove. Penicillin as an infection-fighting element is another. Alexander Fleming was keen to find an effective means of fighting infection after seeing the effects of infections in dying soldiers. It was his untidiness as a worker which led to his greatest discovery. In the summer of 1828 he went away for a holiday, but left a clutter of plates growing various bacteria lying about his desk. After his return, whilst working on an influenza virus he noticed that mould had developed accidentally on a staphylococcus culture plate, and that the mould had created a bacteria-free circle around itself. Further experimentation proved that even a weaker-strength mould culture prevented growth of staphylococci. Thus, Fleming initiated the development and practice of antibiotic therapy for infectious diseases. Even the humble cornflake was invented by accident. The development of the corn flake came about because John Harvey Kellogg sought to improve the vegetarian diet of his hospital patients. Whilst boiling wheat to try to produce an easily digestible substitute for bread, Kellogg accidentally left a pot of boiled wheat to stand and become tempered. When it was put through a rolling process, the grains of wheat emerged as large, thin flakes. When the flakes were baked, they became crisp and light, creating the corn flake, which he patented on 31 May 1884.
What things invented in 1880's-1920's?
We tend to hold inventors in high esteem, but often their discoveries were the result of an accident or twist of fate. This is true of many everyday items, including the following surprise inventions.1. Play-DohOne smell most people remember from childhood is the odor of Play-Doh, the brightly-colored, nontoxic modeling clay. Play-Doh was accidentally invented in 1955 by Joseph and Noah McVicker while trying to make a wallpaper cleaner. It was marketed a year later by toy manufacturer Rainbow Crafts. More than 700 million pounds of Play-Doh have sold since then, but the recipe remains a secret.2. FireworksFireworks originated in China some 2,000 years ago, and legend has it that they were accidentally invented by a cook who mixed together charcoal, sulfur, and saltpeter -- all items commonly found in kitchens in those days. The mixture burned and when compressed in a bamboo tube, it exploded. There's no record of whether it was the cook's last day on the job.3. Potato ChipsIf you can't eat just one potato chip, blame it on chef George Crum. He reportedly created the salty snack in 1853 at Moon's Lake House near Saratoga Springs, New York. Fed up with a customer who continuously sent his fried potatoes back, complaining that they were soggy and not crunchy enough, Crum sliced the potatoes as thin as possible, fried them in hot grease, then doused them with salt. The customer loved them and "Saratoga Chips" quickly became a popular item at the lodge and throughout New England.Eventually, the chips were mass-produced for home consumption, but since they were stored in barrels or tins, they quickly went stale. Then, in the 1920s, Laura Scudder invented the airtight bag by ironing together two pieces of waxed paper, thus keeping the chips fresh longer. Today, chips are packaged in plastic or foil bags or cardboard containers and come in a variety of flavors, including sour cream and onion, barbecue, and salt and vinegar.4. SlinkyIn 1943, naval engineer Richard James was trying to develop a spring that would support and stabilize sensitive equipment on ships. When one of the springs accidentally fell off a shelf, it continued moving, and James got the idea for a toy. His wife Betty came up with the name, and when the Slinky made its debut in late 1945, James sold 400 of the bouncy toys in 90 minutes. Today, more than 250 million Slinkys have been sold worldwide.5. SaccharinSaccharin, the oldest artificial sweetener, was accidentally discovered in 1879 by researcher Constantine Fahlberg, who was working at Johns Hopkins University in the laboratory of professor Ira Remsen. Fahlberg's discovery came after he forgot to wash his hands before lunch. He had spilled a chemical on his hands and it, in turn, caused the bread he ate to taste unusually sweet.In 1880, the two scientists jointly published the discovery, but in 1884, Fahlberg obtained a patent and began mass-producing saccharin without Remsen. The use of saccharin did not become widespread until sugar was rationed during World War I, and its popularity increased during the 1960s and 1970s with the manufacture of Sweet'N Low and diet soft drinks.6. Post-it NotesA Post-it note is a small piece of paper with a strip of low-tack adhesive on the back that allows it to be temporarily attached to documents, walls, computer monitors, and just about anything else. The idea for the Post-it note was conceived in 1974 by Arthur Fry as a way of holding bookmarks in his hymnal while singing in the church choir. He was aware of an adhesive accidentally developed in 1968 by fellow 3M employee Spencer Silver. No application for the lightly sticky stuff was apparent until Fry's idea. The 3M company was initially skeptical about the product's profitability, but in 1980, the product was introduced around the world. Today, Post-it notes are sold in more than 100 countries.7. Silly PuttyIt bounces, it stretches, it breaks -- it's Silly Putty, the silicone-based plastic clay marketed as a children's toy by Binney & Smith, Inc. During World War II, while attempting to create a synthetic rubber substitute, James Wright dropped boric acid into silicone oil. The result was a polymerized substance that bounced, but it took several years to find a use for the product.Finally, in 1950, marketing expert Peter Hodgson saw its potential as a toy, renamed it Silly Putty, and a classic toy was born! Not only is it fun, Silly Putty also has practical uses -- it picks up dirt, lint, and pet hair; can stabilize wobbly furniture; and is useful in stress reduction, physical therapy, and in medical and scientific simulations. It was even used by the crew of Apollo 8 to secure tools in zero gravity.8. Microwave OvensThe microwave oven is now a standard appliance in most American households, but it has only been around since the late 1940s. In 1945, Percy Spencer was experimenting with a new vacuum tube called a magnetron while doing research for the Raytheon Corporation. He was intrigued when the candy bar in his pocket began to melt, so he tried another experiment with popcorn. When it began to pop, Spencer immediately saw the potential in this revolutionary process.In 1947, Raytheon built the first microwave oven, the Radarange, which weighed 750 pounds, was 51/2 feet tall, and cost about $5,000. When the Radarange first became available for home use in the early 1950s, its bulky size and expensive price tag made it unpopular with consumers. But in 1967, a much more popular 100-volt, countertop version was introduced at a price of $495.9. Corn FlakesIn 1894, Dr. John Harvey Kellogg was the superintendent of the Battle Creek Sanitarium in Michigan. He and his brother Will Keith Kellogg were Seventh Day Adventists, and they were searching for wholesome foods to feed patients that also complied with the Adventists' strict vegetarian diet. When Will accidentally left some boiled wheat sitting out, it went stale by the time he returned. Rather than throw it away, the brothers sent it through rollers, hoping to make long sheets of dough, but they got flakes instead. They toasted the flakes, which were a big hit with patients, and patented them under the name Granose. The brothers experimented with other grains, including corn, and in 1906, Will created the Kellogg's company to sell the corn flakes. On principle, John refused to join the company because Will lowered the health benefits of the cereal by adding sugar.We tend to hold inventors in high esteem, but often their discoveries were the result of an accident or twist of fate.

How much was Percy shaw paid per mile for his invention of cats eyes?
That's a fable. Percy Shaw's was never offered a 'per mile deal' for this invention of Cat's Eyes by the British government or anyone else. Percy Shaw could have made a lot more money from the royalties of his invention had he allowed it to be manufactured abroad. However since, in his words, he didn't trust foreigners except to make the face plates, the money he made was always limited because he insisted on only allowing the supply of Cats Eyes glass and their rubber housings to be manufactured in his factory.
