been there. done that.
always wondering why folks shy away from acquiring power? as though, power is a bad thing. perhaps they don't trust themselves with it? i don't have problem with power. foods and women, on the hand, are problematic.
question, is a sphere (3-D) a stable shape?
Depends what it's a sphere OF. A sphere of mass in outer space (i.e., relatively far from other masses) held together by its own gravity can be very stable - it may remain spherical or almost so for millenia. A sphere of water on a table in my kitchen, not so much.
Also depends what kind of stability you're talking about. If you mean, e.g., a hard ball lying on the flat surface -- it's relatively hard to crush (harder than a cube of the same material), but very very easy to roll (unlike a cube of the same material).
