Well, a new problem is upon us: the homework question. The first has been posted on our site. What should our policy be for homework questions?

Policy We do not try to decide which questions are homework, and we don't use a special tag. Users that want to receive hints rather than full answers should say so, and answerers should honor such requests (by not posting details or hiding them in spoiler tags). Other than that, the usual quali...

I see questions like this every so often, usually the poster doesn't just copy and paste the text directly from their assignment, but one did as How to find ring of coverage of GPS Satellite on WGS-84 ellipsoid?. None of the flag categories really fit, but I think it should be removed, if only t...

We (the moderators) haven't really discussed requesting a new moderator from the Community Managers. We know that it's an option... and if the users feel like the moderation of the site is somewhat lacking, we're happy to consider your point of view on the subject but, as of right now, we don't t...

-The above workup should be pretty easy to understand. -The only tough task is to understand the approximation in 3rd last step.

I have an intriquing question and, after searching whole Google, found almost no information. I simply don't know where else to look for answer and so I am asking you. When I was a child, my parents travelled with me to Egypt and there, they bought me a little scarab beetle carved of some stone,...

For the reaction, $$\ce{M -> M+ + e-}$$ the heat liberated is highest for lithium owing to its high negative $E^\circ$ value so one would think that the reaction must be most vigorous. The reason behind the more violent reactivity of potassium rather than lithium lies in kinetics and not i...

I self-realized an interesting property today that all numbers $(a,b)$ belonging to the infinite set $$\{(a,b): a=(2l+1)^2, b=(2k+1)^2;\ l,k \in N;\ l,k\geq1\}$$ have their AM and GM both integers. Now I wonder if there exist distinct real numbers $(a,b)$ such that their arithmetic mean, geometr...

Since I'm not that good at (as I like to call it) 'die-hard-mathematics', I've always liked concepts like the golden ratio or the dragon curve, which are easy to understand and explain, but are mathematically beautiful at the same time. Do you know of any other concepts like these?
