While bed-ridden for few days due to viral fever, discovered that urge for creating PJ’s could sometimes be contagious too. So here’s one.
Steve Waugh, the Physics student, gives a Statistical Mechanics exam and while checking on his corrected answer-sheet founds that he has received zero marks for a certain problem (related to the entropy of a gas in grand-canonical ensemble). He walks to the instructor and inquires what’s wrong. Instructor goes through Steve’s solution, ponders for a few seconds and then replies,
“Mate, you have just dropped a Gibbs factor!”
