Chemists accidentally discover new
explosive computer chips which will aid in many scientific applications. That's the mark of a true scientist, me thinks, someone who has a batch of silicon blow up in their face and instead of (or maybe in addition to) swearing and screaming thinks "my, that was a very clean burning flame, what can I make with it?"
A fellow electronics technician from back in my days at the FAA used to tell everyone that electronic circuits actually worked by shuttling around small packets of smoke. As proof, when you short something on the circuit board it "let's the smoke out" and the thing doesn't work anymore.
