comment Is Lewis Carroll's reasoning correct?
After reading this question, I have to fight the urge to put two black backgammon stones in a bag.

comment Can I use the “Secretary Problem” to find the worst candidate, too?
@JørgenFogh Interesting thought. Can you give examples which use ordinal (not interval/ratio) data which won't work? Or are interval/ratio algorithms the exceptions you were referring to? ACtually, I think maybe I should ask this in its own question.

comment Why is it trivial that $\left(1+\frac{2\ln3}{3}\right)^{-3/2}\leq\frac{2}{3}$?
+1. "Trivial" does not mean "obvious" or "quickly proven". It means that, whatever amount of work is needed for the proof, it is uninteresting grunt work. Of course, being obvious makes a proof also trivial, but people forget that not everything trivial is also obvious.

comment Is computer science a branch of mathematics?
As a computer scientist writing a Ph.D. on Requirements Engineering, I could argue that computer science is in fact a branch of social sciences, not mathematics :P

comment Pedagogy: How to cure students of the “law of universal linearity”?
This is a great question, refutation of such a law is needed in so many more areas other than math. On Cooking.Stackexchange, we have to explain at least once a week that bacterial growth is not linear, so keeping your food at almost fridge temperature doesn't mean that it will be safe as if you had kept it in the fridge... but the next question will again assume that it is true. Or even worse, the next answer.
