Start the Countdown Thinkstock When you imagine inventors, you probably picture a lone genius in a laboratory concocting brilliant devices, experimenting and redesigning until some concept or contraption works perfectly. At that point, the new invention is unveiled to the world, a stunning piece of new technology that instantly changes everything. Well, you've got part of it right.
Today, GPS is an essential tool for national defense strategy, scientific research, and homeland security. It also serves as an important modern technology for navigational purposes.
The technology of today is the Global Positioning System, which uses the global navigation satellite system managed by the government of the United States to pinpoint locations on a map. This was developed in by the U. Department of Defense, but it only became fully operational in The technology developed from satellite navigation experiments that tracked U.
With the help of satellites, submarines were able to detect changes in radio signal position based on the "Doppler effect. The development of chemotherapy drugs has saved countless lives that may otherwise have been lost to cancer. Goodman — and Alfred Gilman — When was it invented? The s Why is it significant?
Goodman and Gilman's work led to significant improvements in cancer-fighting medicine. The ongoing development of chemotherapy treatments has led to a decline in cancer patient mortality rates.
Today, cancer and chemotherapy are sadly two commonly understood words. The use of chemotherapy for cancer treatment started in the s when two pharmacologists from Yale University, Louis S.
Goodman and Alfred Gilman, made observations that nitrogen mustard, a chemical warfare agent, suppressed the growth of lymphoid and myeloid cells.
The pair began to research the effects of using mustard agents in treating lymphoma, first experimenting on mice, then injecting nitrogen mustard into a patient with non-Hodgkin's lymphoma.
They discovered that, although the patient had to return for repeat injections, the tumor masses were significantly reduced from the treatment. The results of their initial research were published in Their study sparked an interest in the subject for other scientists, and, after World War II, further research uncovered the benefits of folic acid in treating cancer.
Since then, researchers have honed in on more advanced combination chemotherapy techniques, and countless lives have been saved. Since the s, cancer mortality rates have been steadily declining. You may never have had a chance to play your Xbox if Goldsmith and Mann hadn't developed their simple target-hitting game in Video Games Thomas T.
Video games are wildly popular in today's world—the vast majority of American children and adolescents play them. Studies have suggested that video games have cognitive, emotional, and social benefits, such as aiding in the development of spatial skills and problem-solving skills and improving focus and creativity.
Aside from social networking, the most popular computer-based pastime is video gaming.
A video game allows interaction between a user and a device with video feedback. The first video game was actually an analog electronic game using a cathode ray tube. Called the "cathode-ray tube amusement device," it was created by Thomas T.
Cathode-ray tubes were a ubiquitous element of life in the 20th century and were essentially the element that facilitated the electron beams that allowed images to appear on television screens.At that point, the new invention is unveiled to the world, a stunning piece of new technology that instantly changes everything.
Well, you've got part of it right. There's certainly a lot of redesigning and experimenting when it comes to inventions, but it takes a lot longer than you think. Trying to predict the future is a fool's game. What seems a failure at first (like, say, the electric light) becomes indispensable.
And what seems destined to succeed (Hello there, Apple Newton. 35 Inventions That Changed The World. From ancient tools to the latest digital advances, human inventions that changed the world and transformed life on the Earth.
