Tiny switch, Bell Labs made it, Sparked the silicon age, can you believe it?
Fun Fact
First silicon transistor: In 1954, Texas Instruments revealed the first commercial silicon transistor by dropping a working one into a beaker of hot oil to prove its heat resistance.
Glossary
transistor (noun)
A semiconductor device used to amplify or switch electrical signals and power. John Bardeen, Walter Brattain, and William Shockley invented the device at Bell Laboratories in December 1947.
