comment minimal po2 surface for sprite arrangement
@Henry: I understand what you are saying - the solution has boundaries. I'd even go further and say that there's probably an upper bound (the first po2 greater than 2*n pixels). My problem is that, even within that boundary, there are lots of possible combinations of dimensions. I'm looking for a formula or algorithm that finds the optimal one, without manually calculating all the possible ones; or else, some proof that such thing doesn't exist.

comment minimal po2 surface for sprite arrangement
Thanks for your answer. I've re-tagged my problem as a packing problem. However, I don't think you have answered the question; you have narrowed the search (I didn't think about multiplying height and width... ) but I was looking for the minimal solution not one randomly chosen from the "many possibilities"... choosing the minimal one was kind of the point of my question. Also, you didn't say anything about generalizing. Nevertheless, your answer has been useful to me, so +1.

comment Mathematical difference between white and black notes in a piano
Well actually I think I didn't know enough to ask my question properly. My musical knowledge is so limited that my first impulse was asking "What are the maths behind music". But I thought that wasn't specific enough so I tried something more concrete. The answers I've received to my second answer actually helped me with that first question I didn't know how to ask. I appreciate the point you made with the different keyboard layouts and the classroom. Thanks, +1!

This was very interesting. I actually thought that the Diatonic Scale was '222222'. So +1 for you. Two things though: a) why do you think Locrian mode is awesome? b) You actually didn't speak about black and white keys at all... maybe you forgot a closing paragraph?

Thank you. Your answer provided historical and some poetical background, as well as purely mathematical. The math part, however, is very similar to Qiaochu's, so I'm giving the answer to him. Yours was quite enjoyable, so +1 to you. You should write more answers here :).

Hi Carlos! Your answer was very good, and it actually helped me understand Qiaochu Yuan's better. I'm giving him the correct response because he was faster, but yours was a close second - so +1 to you, and thanks!

Thanks Qiaochu Yuan. Your answer was very extensive - and very fast. I'm accepting your answer.
