Who Invented the Microwave?

Who Invented the Microwave?...

One of the fastest, most convenient and easiest ways to cook, the microwave or microwave oven is widely used in many households today. Through dielectric heating, this kitchen appliance can efficiently cook or heat various kinds of food. With the aid of radiation, it is possible to heat polarized molecules as well as water. Aside from its important principles and aspects, it is also good to know the history of this cooking equipment including who invented the microwave. The Invention of the Microwave Who invented the microwave? An engineer named Percy Spencer accidentally discovered the use of microwaves to cook food. In happened some time in the 1940s, when he was trying to build radar sets for the commercial electronics manufacturer Raytheon. He noticed that the chocolate bar situated right inside his pocket melted because of the microwaves that were present in the area where he was working. Thereafter, he went on to experiment and tried to cook popcorn. Next, he and his associates tried to cook an egg, which eventually exploded right in the face of one of them. After that, he and his crew experimented on a metal box, which they fed with microwave power. It became a high-density electromagnetic field, which allowed the food temperature to rise quickly. Raytheon decided to file a patent for Spencer’s invention on October 8, 1945. The kitchen appliance was tested for some time in a restaurant in Boston, Massachusetts. After that, Raytheon decided to build the very first microwave oven called the Radarange. Additional Facts and Other Interesting Information The earlier models of the microwave were big and quite expensive. A basic unit usually measured 1.8 meters or 6 feet tall. Meanwhile, the approximate weight of every product was 340...
Who Invented Atari?

Who Invented Atari?

The history of Atari began in 1972 when the company was founded by Nolan Bushnell and his associate Ted Dabney. Originally the firm was called Syzygy but Bushnell later changed it to Atari. Beginnings and Early Success A year before the company was founded Bushnell hired Al Alcorn to recreate the Odyssey game Tennis for Two. The result was Pong. When the game was released in 1972, it became a huge hit. The Atari Company was founded that same year (the word Atari means go in Japanese. Sometimes it is also translated as to hit the target). The success of Pong (150,000 copies sold) marked a significant turning point in the history of Atari. In 1975, Bushnell sold the company to Warner Communications. It was under Warner that the gaming platform attained success. The Atari 2600 was so popular the sales made up a third of Warner’s profit for the first few years. In 1980 the Atari home video system made nearly half a billion dollars in sales. The 1983 Crash In 1983 sales of video games plummeted in the United States. Atari losses amounted to over $550 million. The following year Warner handed over Atari to Jack Tramiel (former head of Commodore). The Atari St came out and sales peaked at $25 million in 1986. Struggles The next stage in the history of Atari involved its struggles with rival Nintendo. Their rival was winning market share so Atari worked on the Lynx system. It was a handheld console complete with color. The Lynx sold poorly for two reasons. Number one, shortage of components prevented it from being released during the 1989 holiday season. Second it cost twice as much as the Nintendo Game Boy. Tramiel had also stressed...
Who Invented the Alkaline Battery?

Who Invented the Alkaline Battery?...

An alkaline battery is a kind of a rechargeable battery or disposable battery that is dependent on the reaction between the compound manganese oxide and the element zinc. Many consumers prefer to use alkaline batteries over zinc-carbon batteries because alkaline batteries have longer shelf life as well as higher energy density. One of the most important materials used in the development of the batteries is the alkaline electrolyte of potassium hydroxide. Before we proceed with the characteristics of the battery, let us look at its history, including the person behind the invention of the alkaline battery. Historical Background Who invented the alkaline battery? The first alkaline battery was invented by one of the scientists of Energizer, Lewis Frederick Urry, in 1959. The prototype battery developed by Urry was displayed at the Smithsonian National Museum of History. In order to prove the durability of the battery, Urry installed the alkaline battery in a toy car and a zinc-carbon battery in another toy car. He raced the cars around a room. As expected, the toy car with the zinc-carbon battery was the first to stop. With the desire of the company to limit the use of mercury in batteries, it introduced the AAAA alkaline battery in 1989. Additional Information and Other Important Details An alkaline battery has a nominal voltage of 1.5 volts. To attain multiple voltages, it is important to make a series of alkaline batteries. When the battery was discharged, the zero-load voltage may vary from 1.5 volts to 1.65 volts. The voltage depends on the level of zinc oxide and manganese oxide in the electrolyte. Almost all alkaline batteries can be recharged. However, to do this successfully, there are some pointers to know. The first thing one should...
Who Invented the Cell Phone?

Who Invented the Cell Phone?...

The mobile or cell phone was invented by Martin Cooper in 1973. The history of the cell phone shows that Nathan Stubblefield had a patent in 1908. However the patent was for cave radio phones and not the mobile device as we know it today. Early History As stated, Stubblefield’s patent was for cave radio telephones, as the device was known then. The mobile phone’s origin can be traced back to the 1940s. Bell Labs had already made some mobile base stations. These were refined in the 1960s but they were mainly for radio telephony. The main users of radio telephony during those days were the military. These hand held radio gadgets had been patented in 1969 to George Sweigert. The history of the cell phone began in 1945 and these early phones are now called zero generation phones. It consisted of a solitary base that would cover a specific spot and had very limited coverage. First Generation Phones Cooper’s invention was patented on October 17, 1973. the first phone call was made by Cooper months before he applied for the patent, on April 3, 1973. He made the call to Dr. Joel Engel, a researcher at AT&T’s Bell Labs. Cooper was working at Motorola at the time, and the call was made with several media people present. Soon after, companies started making cellular networks. Although the telephone was still dominant, other companies started coming out with cell phones, although they were still large and heavy. Second Generation Phones The next stage in the history of the cell phone was the development of 2G (second generation) phones. Among the earliest 2G phone systems were GSM, IDEN, and IS-95. GSM networks started appearing in 1991 (specifically in Finland). Compared with...
Who Invented the Gatling Gun?

Who Invented the Gatling Gun?...

The Gatling gun is arguably one of the more famous and recognizable among all of the firearms ever made. Due to its distinct appearance and its unique capabilities, many are familiar with Gatling gun, even those who are not well-versed with firearms. Despite this familiarity even with the most gun-averse of laymen however, not many know who invented the Gatling gun along with the history of its design and development and its impact on modern warfare. As its name suggests, it is easy to remember who invented the Gatling gun. This because the man who invented the Gatling gun lent it its name. The man who invented the Gatling gun is Richard J. Gatling, an inventor responsible for numerous patents in the United States in the latter half of the 19th Century. Despite the Gatling gun’s fearsome reputation in the battlefield, the man who invented the Gatling gun reasoned his newly-designed gun will actually lessen the casualties in warfare. Since the Gatling gun will allow relatively few personnel to deliver tremendous fire power (for its time), less soldiers will then be needed to fight wars and therefore lesser battle casualties. Of course we all know that the idealistic notion of Gatling that fewer men will die in battle as a result of his invention’s tremendous fire power was baseless. But the man who invented the Gatling gun was in part right since for the first time in history, a few personnel with the help of his invention will be able inflict massive damage to the enemy. Battle before was mostly a man-to-man struggle between combatants but with the Gatling gun, a soldier can single-handedly inflict heavy casualties on the other side. More than a hundred years after its invention,...
