Answer to the Question 09/03
DELICATE BALANCE
The question was:
Consider a lead pencil balanced on its point. Estimate how long
it will remain standing if quantum effects (uncertainty principle) are
taken into account. Compare that answer with the time it takes for
thermal effects (air molecules, thermal radiation (if it's in vacuum))
to topple it.
