Electronics

Electronics comprises the physics, engineering, technology and applications that deal with the emission, flow and control of electrons. Basically, electrons store your money, monitor your heartbeat, carry the sound of your voice into other people's homes, bring airplanes into land and guide cars safely to their destination—they even fire off the airbags if we get into trouble. It's amazing to think just how many things electrons actually do! As a matter of fact, the identification of the electron in 1897, along with the invention of the vacuum tube, which could amplify and rectify small electrical signals, inaugurated the field of electronics and the electron age. Now, electronics are widely used in information processing, telecommunication, and signal processing. No wonder they have transformed many areas of our lives, and we have become overly dependent on them.
