    A nifty idea looking for a purpose in 1947 changes the world as we know it...

    You use this thing every day, in fact to read this, you're using it right now. How does it work? What is inside and what does water have to do with a transistor radio?

    In this episode of the weekly podcast Foundations of Amateur Radio I look at the transistor and explain how it works and why it's not hard to understand how a transistor can be both a switch and an amplifier.

    And here I thought all these years that the water in a transistor was to provide the steam that made it work.

    The mind boggles. I'm curious how steam turns into black smoke?
