As I believe you target this to mathematicians mainly, I would suggest putting some more sophisticated (a mathematics "milestone") equation as an example, instead of simple quadratic equation.
I thought HN is a place where people don't take everything so seriously (or maybe I should provide some emoticons not to be taken so seriously?). And I also don't understand why people always try to lump together such comments into troll/hater/(in this case)Python-enthusiast category (ever heard of sarcasm?).
I won't explain myself, smoyer's example (except the 'hate' part) pretty much sums up what I think about Perl. And yes, I believe it's a great language, although looking from a state of development of modern languages point of view, objectively speaking, it's a bit outdated language. And therefore, in my opinion, will find less and less applications in the future (and yes, Python is and will be its main competitor in many fields).
"Take five" was actually a great jazz theme that I always compare to great programming, saying: "You want to know how the great code looks like? Listen to this."
