Mathematics-filter: If there are seven funds with various charges, how can I work out the allocation to these funds of a fixed amount so that the weighted mean charge is below a certain level and the allocations are of similar sizes? [more inside]

Best books, websites, lecture series on game theory and its applications for smart people who understand mathematics but can't stand trawling through pages of unnecessary complex formulae?

Why is it that when I solve the inequality 0 ≤ arccos(x) <> cos(π/4)? Why do the operators switch direction?> [more inside]

Imagine a cube-shaped building, with ten cube-shaped rooms along each side (10 rooms long, 10 high & 10 deep). Each cubular room has 4 walls, 1 ceiling and 1 floor. Each of the 6 interior
surfaces in all 1000 cubular rooms is decorated with a different piece of art.
The rooms can be moved around the building, as if it were an enormous Rubik's cube, but they can also be spun on their axes, so all 6 walls of all 1000 cubes is capable of touching all the others (if the cube is so arranged).
How many combinations of art within the 'Cube Gallery' are possible? If you can run me through the workings of the maths I would be extra grateful. Also, what technical words/phrases/language are useful/interesting in expressing this concept? [more inside]

How can a major key sound confident and happy, while a minor key can sound sinister or sad? Is it just centuries of musical brainwashing, or is there a real mathematical explanation?
