The basic idea of cyborg is a humanoid i.e. part human and part machine. The word “cyborg” was coined by a group of scientists working at NASA. In 1960, two scientists of NASA had discussed the probable advantages of a human that could have machine […]
Laser printer works on a principle called the static electricity. A charge is built up on any object that can be a balloon, your body etc. we know that atom with opposite charge attracts each other and the objects bind with the others having atoms […]
A capacitor or condenser is a passive electronic module that has a pair of conductors and is separated by a dielectric or insulator. While a probable difference subsists across the conductors, an electronic field is present in the dielectric. This electronic field stores energy and […]
The credit for inventing the steam engine cannot be given only to a single inventor as several contributions were made centuries ago. Dating back to the first century A.D, the idea of steam engine was first conceived by a Greek scientist and mathematician called Hero […]
Today almost everyone is using cell phones but do we know how it works? Cell phone is basically the combination of two technologies or inventions. One is the telephone and other is the radio. Telephone was the invention of Graham Bell in 1876 and radio […]

Jet engines propel the aircraft by releasing fast flowing liquid fuels. According to Newton’s third law of motion, “every action has an equal and opposite reaction”, the speed with which the fuel is released by the engines propels the machine in the opposite direction with […]
Earphones are an evolved form of headphones that was first invented by Nathaniel Baldwin in his kitchen and was supplied to the US Navy. Nathaniel Baldwin was born on December 1, 1878 in Millard County, Utah. Even when he was a child, he had a […]
The concept of Holography was invented by a Hungarian-British scientist and engineer Dennis Gabor in 1947. He was awarded a Nobel Prize in Physics for this work in 1971. Born in Budapest in a Jewish family his name by birth was Gunszberg Denes. After working […]
A circuit breaker is used to protect electrical circuits from all sorts of damage caused by overloading of power or short-circuit. This procedure is done automatically. The main function of these sorts of switches is to discover a fault condition and interrupt the flow of […]
