Tunable Quotes

I really wanted to find a piano for the farm house. There were so many free pianos on Craigslist, I thought, 'Let's get as many free pianos as we can and stick them all in the barn.' I got eight in a short period of time, only six of which were tunable, but it's still quite funny. (Neko Case)

Feynman uses Dirac's notation to describe the quantum mechanics of stimulated emission. ... He applies that physics to several physical systems, including dye molecules. ... In this regard, Feynman could have predicted the existence of the tunable laser. Furthermore, Feynman made accessible Dirac's quantum notation via his thought experiments on two-slit interference with electrons. View quote
