We are used to seeing new technologies being invented virtually every day. Now you can use a toaster which is flexible and can be rolled after every use. You can watch movies and shows in 3D. You can get access to the web from virtually any place in the world. Even though these technologies are a huge trend and enjoy great popularity, only time will tell whether they are revolutionary. There are other older ones which have made a huge impact on our lives and on society as whole.
Up until the 19th century, electricity was just something created in labs and used for experimentation. Thanks to the introduction of modern research techniques, electrical engineering took new heights. Thomas Edison is credited not only with the invention of the electric bulb, but also with the development and establishment of the first large-scale network for electrical supply. The network started operating in 1882 and covered a small area of Lower Manhattan.
If you try to imagine what your life would be like during a single day without electricity, you will really appreciate this invention and its importance for the industrial, social and technological development. All of the devices that we use today depend on electricity. This applies not only to the gadgets that we work on and have fun with but also to technologies which sustain the life and wellbeing of people.
The world’s first practical telephone was invented by Alexander Bell in the 1870′s. This invention truly revolutionized communication as it allowed people who were great distances apart to exchange messages directly and instantly. The advancement in communication helped for the development of trade, emergency services and many more aspects of life.
Today, the phone is a portable device which we carry in our pocket and which has numerous capabilities in addition to allowing us to make voice calls. With the introduction of gadgets such as Google Glass, the phone is revolutionized to a small device integrated into the frame of glasses. Given the craze over this new invention, some researchers suggest that in the future, the phone will become a chip which is placed inside the body.
The first computers were introduced in the 1930′s and early 1940′s. In 1936, Alan Turning developed the so called Turning machine which is considered to have been the blueprint for the computer. In 1937, Atanasoff and Berry developed the first electronic digital computer. In 1941, Konrad Zuse invented the first programmable computer. The rest is history, as they say.
In the beginning, computers were used primarily for complex mathematical operations in various fields including science and statistics. Personal computers came into use in the 1960′s and have been around ever since then. Now computers come in a variety of shapes and sizes and many of them are perfectly portable with the size of the smallest gadgets decreasing dramatically. We use them for all sorts of things from doing work to watching movies. They have been integrated into our lives to such an extent that many schools are now introducing typing along with handwriting to the youngest students.
