Coolest Invention
Posted by: Techpin in science

Along time, society's life has changed, and progress is a natural tendency of humanity. There are some great people who changed whole world's lifestyle with their inventions, and just wondering how life would be without their ideas brings strange answers. Nowadays we live at one-click distance from almost everything we need, our lives are part of this informational society, and we are more and more surrounded by gadgets, devices and machines which make our work easier and facilitate entertainment.

We all have a mobile phone in our pockets but how would we have communicated if Graham Bell wouldn't have thought of this ""apparatus for transmitting vocal or other sounds telegraphically", which anyway, has changed very much along time. The first transmission (bi-directional) of clear speech was made in 1876, between Bell and Watson, and the words "Mr. Watson, come here, I want to see you." remained in history as the first words transmitted by telephone. In the beginning the Gray transmitter, based on liquid, was used, but it was not practical for the products designed for commercial purposes, so in time the system changed.

The first telephone call was made in 1876, as I said, from Bell's home in Ontario (Brantford), to his assistant located in Paris, Ontario, at about 10 miles (16 Kms) distance. Bell can be compared in inventions' history to Henry Ford, because he was not the first one to experiment this kind of transmissions, but he managed to design a commercial version for this "device" and he was a pioneer in introducing his invention into a commercial system and somehow we can say that telephone industry was set up by A.G. Bell.

Getting closer to our days, the concept of cellular phones appeared in 1947 and it is strongly linked to car mobile phones' functioning system. The inventor of the first modern portable handset is Martin Cooper, a former manager of Motorola, which made the first call on such a portable phone in 1973. He made the call to Bell Labs head of research, who was in the same time his rival, because they were working on research for the same device. Motorola incorporated this technology into a portable device, which had been designed for car use. In 1977, Bell Labs, the rivals, constructed the prototype for this cellular system, and one year later, they offered the device to 2000 trial customers. In Tokyo, 1979, the first telephone system operated and in 1981 Motorola and American Radio started a telephone test system, in U.S.A., but in Washington and Baltimore area. The first American analog cellular service was made available in 1983 by Ameritech. By 1987, cellular telephone industry reached one million subscribers, and the airways became more and more crowded with radio transmissions.

So, since 1947, when the first concept of mobile phone appeared, and until 1987 when there was already a market created with a substantial number of subscribers, have passed 40 years. This means that inventions take time to integrate into people's life and to really become something usual for them. And since 1987, the standards for transmissions developed continuously and today we have reached the wireless networks level, which offers us the possibility to be connected permanently to a carrier network, and also the phones have been developed so much that they differ a lot from the initial telephone concept. Of course, they still have the same main purpose: voice calls, but plenty of features have been added.
I think that electricity is another important invention which changed a lot humans' lifestyle and made a lot of things easier. Think about not having electricity for a day...no, it's enough not to have electricity and we are wasted. A lot of appliances work based on electricity, and the era of mechanical force has gone. Electricity is the engine both for our work and entertainment. Electricity is one of the basic elements in nature, and currently it is the most widely used form of energy. The electricity is the secondary energy source, converted from other sources, like coal, gas, oil, and other primary sources. Before the point electricity was introduced in common life, 100 years ago, people lit their houses with kerosene lamps, and they did not use refrigerators to conserve foods...they cooled food in iceboxes. The rooms were warmed by burning wood or by using stoves with burning coal. Light bulb's invention brought electricity in people's houses, and since then, electricity has been used in a very large variety of industries, and it is the main engine who runs our lives right now. It is interesting how to think about how life would have been if we didn't have any resources to power our laptops and be connected every second, like we are now.

The first digital computer was invented by Shannon, in 1940, and represented the start point for all the programmable devices which surround us today. The first operational computer was created by Zuse in 1941, and its name was Z3, but only in 1977 the personal computer entered the market with a commercial purpose. It was a entertaining tool, and it also helped financial calculations, but it also boosted creative work efficiency. We use it now for social networking, watching high definition movies, listening to music, finding recipes for our favorite foods, and sometimes, we use it for working. The history in this domain was written by companies and people like: Apple, Intel, IBM, Microsoft, Steve Jobs, Bill Gates and many others who had smaller or bigger contributions for this industry's development. Internet and all the industries Internet-related have also changed so much our lifestyle, that I am watching and studying how common gestures and activities like clicking, browsing, blogging, e-commerce have become and their fast evolution is happening in front of our eyes.

There are much more inventions which changed humanity and which I didn't mention here, but we wouldn't like to forget about Flemmings, who discovered penicillin, the invention of micro wave oven, which we should thank Percy LeBaron Spencer for, and many cool inventions!
