The idea sounded funny to the company as Teflon would not stick to any surface, but they provided him what he wanted. The hovercraft was invented by Christopher Cockerell, the same man who invented radar while he was a worker at Marconi.
The basic idea behind his invention was to create an Air Cushion Vehicle that could sail on the water with increased speed. All the idea was birthed when he was aware of Normandy landings, and he figured a way to transport troops safe up a beach. While working in his boatyard at Norfolk, he set up a Ripple Craft, where he placed set two tins by placing one inside the other and reversed the connections on a hairdryer.
This proved that air cushion could be formed to reduce drag and allow boats to sail faster. He finished building the SR-N1 with Government support, and it was capable of working on water and air. After its launch, the hovercraft flew from France to England. Jack Kilby was sitting in his office at Texas instruments, a small establishment in Dallas, famous for inventing the transistor radio.
Jack was pondering on a though that the components of an electric circuit can be built from silicon. As a new staff, Jack could only be at work while others were on vacation, and he was lost in the thought of building a semiconductor.
He reasoned that building capacitors and resistors out of semiconductors would make the circuit compact. He concluded on listing all components that could be built out of silicon, and they include transistors, capacitors, diodes, and resistors. He presented his idea to his boss in the form of a working model and was approved to proceed. Alas, he successfully built a solid circuit, the size of 11 by 1. Another inventor, named Robert Noyce worked with his colleagues in California to develop unitary circuits.
He wrote a detailed application for his patent, and both patents were granted. Jack Kilby was later awarded a Nobel Prize in the year for his invention. A microchip is a small device, smaller than the fingernail, and it contains an integrating circuit in a microprocessor. The microchip was invented a year after the integrating circuit was invented by the same inventors, Jack Kilby and Robert Noyce.
Arguably, the integrating circuit is one historical invention that is the most important to humankind and technology today. It is hard to find a computerized or smart device without a chip technology. A microchip can also be called a microprocessor because it carries the central processing unit of a computer on the integrating circuit.
Jack was a staff at Texas instruments while Noyce worked in a semiconductor corporation when they both invented the microchip. An artificial pacemaker is a medical implement used to stimulate the heart by replicating the action of a natural pacemaker. It was invented in by Wilson Greatbatch. This pacemaker is a special invention, because of its size and understory. Before pacemakers were large and external, and they required the mains power supply to function because battery technology was not advanced at the time.
After inventing the pacemaker, Wilson pursued a compact type pacemaker that can be implanted. It was successfully demonstrated in a dog before being publicized.
In , Wilson was working at Buffalo when he invented the artificial pacemaker. He was working on a heart rhythm recorded when he mistakenly used the wrong electronic component. When he discovered his mistake, he observed the device and saw that it supplied electrical pulses instead of recording them. He never saw it coming. The first television remote control was invented in by Zenith Radio Corporation. It was called lazy bone as it can be operated from a distance and is capable of switching the television on and off.
It can also change channels, but it is a wired connected remote control. The wire connects the remote to the television. Eugene Polley invented the first wireless remote control in , an invention he called the flash-Matic.
The Flash-Matic worked with four photocells positioned in each corner of the television. The four controls are activated by a flashlight pointing in the directions. The Flash-Matic wireless remote control could on and off picture and sound, and control the channel tuner in a clockwise and anti-clockwise direction. The only limitation of the wireless remote is its inability to function on sunny days as sunlight hits the photocells and change the channels at random.
A solar cell converts energy from the sun into electrical energy through a photovoltaic process. Before the 20th century, some contributors have tested the photovoltaic process with selenium, and it worked.
In , Pearson, we working with Bells company, and Bells was responsible for funding the project at the time. He worked with two other Americans to produce the first solar cell made of silicon to efficiently convert six percent of energy from the sun into electrical energy. His working team created electricity with silicon strips, each strip size not longer than that of a razor blade.
The silicon strips were placed in the sun to trap free electrons and converted them into electrical currents. The invention was announced as a solar battery, and it was first used to power a telephone carrier system in Georgia. Hoops were common since the beginning of the 20th century but were made of bamboo.
It is common amongst Australian school kids as a piece of equipment for exercising, using a hoop for exercising is fun. Then it became a popular demand that was seen as a means of investment for two American manufacturers. Richard and Arthur were toy producers at the time, so they started producing hoops under the Wham-O company.
Hence, a craze was born. Over 20 million Wham-O hula hoops were sold in about six months. They named their invention Hula Hoop.
Some months towards the s, the rate of polio patients increased to about 35,, and it continued like that each year. Jonas Salk was popular for inventing a vaccine to treat or prevent polio.
Every other vaccine for polio came after Salk found a cure to the life-threatening virus. The invention started when Salk started growing the three polioviruses on the kidney cells of monkeys. He killed the viruses using a formaldehyde solution and then injected the monkeys. The injected vaccine prevented them from contracting paralytic poliomyelitis. Later, he began injecting humans with the vaccine, especially already infected children.
The device is intended for industrial applications, and it quickly revolutionizes the way television programming is produced. Earl Bakken develops the first external, battery-operated, transistorized, wearable artificial pacemaker. Sterophonic recordings, which use two separately recorded channels of sound to recreate a sense of space, come into commercial use.
Joseph-Armand Bombardier of Valcourt, Quebec, Canada patented the Ski-Doo, originally christened the Ski-Dog, but renamed because of a typographical error that Bombardier decided not to change. You know it as a snowmobile. Copyright Michael Rich. All rights reserved. Post World War II, the world was very different. Like we have already said before, war can inspire a lot of new technology and innovation. If you were around in the s you probably saw a tremendous boom in electrical devices, gadgets in and around the house, i.
Many people have looked back at the 50s as a golden era, a time period in which the quality of life drastically improved. The optical fiber would change the way we transmit information and communicate with each other over the years. Much more superior than other forms of communication, optical fiber transmitters are capable of sending up to 10 billion bits of information per second.
The first general-purpose electronic digital computer designed for business, the computer gained a lot of attention in the s. Remember the golden era of the VCR the s? You can thank the s for that.
The video cassette recorder was invented in trials and used for BBC. Obviously, the technology was unavailable for the everyday person as it was way too expensive, and television networks simply used it for recording and replaying video and audio signals. Nevertheless, the VCR would eventually make it into our homes, changing the way we consume media. Frank McNamara came up with the idea of the credit card when he went out to supper with a dinner partner.
His partner forgot his wallet, and that gave McNamara the idea for the credit card. His idea was that you would have a card that would be accessible at all times with money on it. Oct 27, Television was not invented in the 's, but it became very popular early in the decade. Everything that happened after that was affected by television. Space races, speeches, now almost every major event could be internationally viewed,.
In the early days, film was the only medium available for recording television programs. Charles Ginsburg led the team that developed a new machine that could run the tape at a much slower rate because the recording heads rotated at high speed.
This allowed the high-frequency responsethat was needed. American airlines ordered the pioneering Comet, but Canadian, British and European airlines could not ignore the better operating economics of the Boeing Boeing became the most successful of the early manufacturers. The first generation ws introduced in the late model year and ended in Polo white convertibles were introduced in the model. It was often referred to as the "solid-axle".
