Tiny lamp spans quantum and classical physics



"Physicists in California have made the smallest ever incandescent lamp using a carbon nanotube as the filament. The nanotube is so small it behaves as a quantum mechanical system but it's just large enough that the classical physics rules of thermodynamics should apply. Analyzing the light emitted from the tiny light will give the team a better picture of what happens in the twilight zone between the quantum and classical worlds."


And the best three response to this article are as follows:


1. How many quantum physicists does it take to change a light bulb?
Three. Two to do it, and one to renormalise the wave function.

2. You Fool! You altered the outcome by observing it!

3. I just replaced all the lamps in my house with these, but they just don't seem to brighten up the room like the old ones, and now my cat is missing.


I love physics humor -- tight but bouncy.
