Trailing the Transistor

2000
Follow the trail of the transistor.In the ever increasing world of computers, one would say the microchip has changed the face of the world. That would be denying credit to the true pathfinder of electronic change. The transistor was the true electronic instrument of change. Discover the transistor and the circuits that revolutionized personal as well as commercial electronics. The walkman, the cellular phone, the citizens band radio, pocket calculator, and yes the microprocessor all owe their existence to the transistor. See how a few basic ideas have led to the modern day microprocessors that are in fact a collection of large numbers of transistors all etched in the circuit. Play the circuit games and put yourself in the role of the electron on the wire.
