Recently, an American shared the Nobel Prize in. From the mundane to the truly spectacular, numerous American inventions have changed the world. Here is a list of 20 things invented by Americans that have become part of everyday life here and around the world. Ferris wheels are a quintessential feature of American amusement parks.
The Ferris wheel was the United States' answer to the French Eiffel Tower, one of many wonderful proposals designed to inspire awe and awe in American hearts. Ferris spent thousands of dollars out of pocket to ensure that the best safety and engineering tests produced the perfect wheel. The original wheel had 36 cars and was 250 feet in diameter. Ruth Graves Wakefield, a delicious treat made with flour, butter, brown sugar and semi-sweet chocolate chips, prepared it by accident in 1930 at the Toll House Inn, a restaurant she owned with her husband that served homemade food in Whitman, Massachusetts.
Dental floss was introduced in 1815 by Parmly, a New Orleans dentist. It was originally made of silk, unlike today's dental floss, which is made of nylon or plastic. Closable cabinets, and then zippers, play an important role in maintaining the practicality of modern fashion. The first lockable locker design was used as a shoe closure, which was thought to be an invention designed to simplify the complex process of buttoning boots that were all the rage at the end of the 19th century.
Headphones help amplify the sounds of people with hearing problems, giving them the opportunity to live a safer and stronger lifestyle. The first electronic hearing aid was invented in 1902 by Miller Reese Hutchinson, an inventor from Alabama. Around 1895, Hutchison invented what he called the akouphone, an electric hearing aid. Although he was not a doctor, he did take classes at the Alabama School of Medicine to better understand the anatomy of the human ear.
Hutchison developed an interest in the subject due to a childhood friend who was deaf. The original Akouphone was rather bulky and impractical, and in 1902, Hutchison invented another version called Acousticon. By 1905, he had ceded the rights to his invention to Kelley Monroe Turner, who would continue to expand and improve the technology and eventually apply it to other inventions. Kouwenhoven developed an academic interest in the relationship between electricity and medicine when, in the early 20th century, it became clear that public service technicians suffered from ventricular fibrillation (fast and unstable heartbeats) and no one knew why.
Between 1928 and 1947, Kouwenhoven and his research team from Johns Hopkins University studied the effects of electricity on the human body. In 1933, the team successfully prevented ventricular fibrillation in a dog's heart by shaking it with electricity. Defibrillators were used successfully for the first time in humans by Dr. Claude Beck in 1947; initially they were only used during open chest operations.
In 1957, Kouwenhoven and his team presented their first prototype and, in 1961, presented the first portable defibrillator. This allows scientists to determine how long ago biological samples stopped collecting carbon-14 and, based on the decay rate, approximately when they died. Managing pedestrian and vehicle traffic at intersections would be almost impossible without the help of the traffic light. The modern electric traffic light as we know it today was invented in 1912 by Lester Wire, a Salt Lake City police officer.
Originally it was just red and green to stop and exit, respectively. In 1868, an early version of the traffic light was introduced in London; however, it was declared a public health hazard after a police officer was seriously injured while operating it, and the project was immediately stopped. The first crash test mannequin was developed in 1949 by Samuel W. He graduated from high school at age 15, after which he attended several universities and worked intermittently for his family's sheet metal business.
Information from research on animal and human corpses was used to design the crash test mannequin, introduced in 1949, which was initially used to test aviation safety. Nowadays, the descendants of these crash test dolls are used in a wide range of situations to simulate the response of the human body. The microwave was not originally intended for use in the kitchen. In 1945, Percy Spencer, an engineer from Maine who worked on the magnetron for Raytheon's radar devices, discovered that microwaves had unintentionally melted the chocolate bar in his pocket.
While others had noticed the effects of the magnetron, they were too afraid to further investigate its powers. However, Spencer soon began using it to heat his food and, in 1946, Raytheon patented the high-frequency dielectric heating appliance, the first microwave. In 1901, Ransom Olds introduced the basic concept through his motor vehicle company in Michigan. Olds is also widely recognized as the founder of the automotive industry in the United States, and one of his vehicles, the Curved Dash Oldsmobile, was the first successful mass-produced car on an assembly line.
The LED has come a long way since its initial use as an indicator light for electronic devices. It was developed in 1962 by Nick Holonyak, Jr. Nowadays, cancer and chemotherapy are, unfortunately, two words that are commonly understood. The use of chemotherapy for the treatment of cancer began in the 1940s, when two pharmacologists from Yale University, Louis S.
Goodman and Alfred Gilman observed that nitrogen mustard, a chemical warfare agent, suppressed the growth of lymphoid and myeloid cells. Since then, researchers have focused on more advanced combination chemotherapy techniques and countless lives have been saved. Since the 1990s, cancer mortality rates have been steadily declining. Cathode ray tubes were an omnipresent element of life in the twentieth century and were essentially the element that facilitated the beams of electrons that allowed images to appear on television screens.
However, since the 21st century, manufacturers of electronic products have opted for LCD and plasma screens. Email became popular in the early 21st century. It has become the preferred form of communication because it allows the fast transmission of messages and, at the same time, saves resources such as ink and paper. It's a common belief that human beings have always been interconnected, but nothing confirms this better than seeing how much the Internet connects to humans in the 21st century.
The Internet, a network of networks, was formally introduced with the National Science Foundation's suite of Internet protocols in 1983, which was funded by the U.S. UU. In 1990, the World Wide Web was established. It was not the same as the Internet, since it simply served as a means of accessing data online through websites and hyperlinks.
However, this laid the foundation for the popularization of the Internet among the public, helping to establish its continued monumental importance in today's world. In fact, the Internet tops this list of inventions because it has created a means for other inventions and related technology to become tools that are so ubiquitous and well-known to humanity. There are many other impressive inventions (both non-American and American, of course) that haven't been mentioned here, but these 20 stand out. You need to do better research.
The World Wide Web was invented by Englishman Sir Tim Berner-Lee. Jet engine? Another Englishman, the light bulb? Another Englishman: Joseph Swan (1878), not Edison. By the way, Edison was a thief. The things he stole from Tesla with the support of JP Morgan.
Please don't misrepresent the story. I can't believe you haven't added toilet paper to the top 10 list. Every time that soft tissue touches your butt, raise your eyes and say: God bless the United States. The United States is often criticized for using up to 25% of the world's resources, while representing only 5% of its population.
In fact, the United States contributes substantially to global growth through its contributions in terms of scientific research and development and the education of foreign-born scientists. Michael Mandelbaum talks about U.S. defense spending as a public good that has given to the world. However, numerous reincarnations of the wheel have been created, which remain a staple of American theme parks and fairs to this day.
The United States of America represents 6% of the world's land mass and about 6% of its population, but its economy generates about 30% of the world's GDP. The economic engine of the United States is not only the largest, but also the most dynamic and innovative, as evidenced by the fact that more than 40% of all Nobel Prize winners are from the U. However, as a percentage of the US economy, this is a low figure compared to most rich countries (0.18% compared to an average of 0.31%). However, it is generally believed that Wire was the first American to invent the traffic light as we know it today.
Recently, an American shared the Nobel Prize in Medicine for understanding the unbearable details of the human immune system. They include the idea that the United States began helping Great Britain only when it attacked itself, and that American aid to Britain before that date was due to the widespread hostility of the American public, provoked by anti-British “isolationists”. Traffic lights were invented in the United States, but they give credit to the first one, which was Garrett Morgan, not Lester Wire. This 4th of July marks the 238th anniversary of the independence of the United States and, while they wave the American flag, attend a parade or celebrate with the colors red, white and blue, they take a moment to recognize the contribution of the United States to the world of science.
In fact, US defense spending accounts for 45% of the world total, a figure that is often described as excessive. . .
