In ‘History of the Computer – the emergence of Electronics’, we saw how the development of Radar during the second world war led to an understanding of pulse technology. At the same time methods were refined for the calculations required for the ballistic trajectories. From these beginnings, the digital computer was developed.

In both science and in technology, a battery is used as a type of device that is used to store energy, making it available for use in an electrical form. They consist of electrochemical devices, including one or even more galvanic cells.
Baghdad Batteries are thought to be the first known in history, dating back from sometime between the years of 250 BCE and 640 BCE. The modern battery began with the Voltaic pile, which was developed by Alessandro Volta, an Italian physici…
Understanding how fiber optics are made and function for uses in everyday life is an intriguing work of art combined with science. Fiber optics has been fabricated from materials that transmit light and are made from a bundle of very thin glass or plastic fibers enclosed in a tube. One end is at a source of light and the other end is a camera lens, used to channel light and images around the bends and corners. Fiber optics have a highly transparent core of glass or plastic…
