Science And Technology
Science and technology is the best thing society could ever ask for. Since the industrial revolution in the 18th century science has been in progress. Some sectors that have been boosted by science and technology are energy, physical sciences, information and communication. The society has greatly gained with the invention of technology.

Infrastructure in the society has grown with the help of science and technology. Modes of transport like electronic railway lines were realized and these actually benefited the society by offering them a better means of transport. In the past, almost everything was analog but thanks to the science and technology we are now being digitalized by the day. The invention of the telephone and radio services has broadened human communication.

The microwave oven was invented in 1946 by an engineer Percy Spencer but the invention itself was accidental involving chance, coincidence and imagination.

Percy Spenser who was working in the Raytheon Corporation on a project related to radars happened to stand near a magnetron, a device that emits microwave radiations, with a bar of chocolate in his pocket and noticed after some time that it had melted.

Further experiments with popcorn and eggs confirmed his suspicions that the microwave radiations emitted by the magnetron were somehow able to raise the temperature of the food placed near it and hence as a result could be used effectively for cooking purposes.

After initial experiments a microwave was built at Raytheon, but it was at first used only for defrosting purposes and also was quite large in size. Later in 1967 Amana, a division of Raytheon introduced the domestic microwave oven in the market which slowly but surely became popular as its price decreased mainly due to its unmatched speed of cooking.

This was the first prototype of the modern day microwave oven eventually becoming one of the most common of all kitchen appliances and changing food habits on a revolutionary level. Anonymous Great Answer Report

The existence of electromagnetic waves was predicted in 1864 by James Maxwell. Hertz was the first person to demonstrate the existence of electromagnetic waves in 1888. In 1894, Bose demonstrated the use of high frequency waves by generating microwaves to explode gunpowder and ring a bell at a distance. Anonymous Great Answer Report
