    {"Point", Black, {12, 3, 15}},  
    {"Point", White, {12, 3, 4}}},

comment What was the first bit of mathematics that made you realize that math is beautiful? (For children's book)
@aidanO Yes, that's certainly an obvious thing to do. Instinctively I avoided doing it that way at the time, and would do the same now. The thing is, primes are different: not just bigger coloured squares, but different from other numbers, and related to each other as strongly if not more so than to their multiples. And then, what colour is, say, 97? (Well, it later gets a colour automatically, since the chart originally went up to 1000.) But would that colour indicate the number's primality well? That's why the white works, for me. (I didn't get into the nature of 1... :)

comment Why we need to know how to solve a quadratic?
@mixedmath No, but there's only one me, SE must think there's two. Not worried really, since I rarely have anything intelligent to say here. :)
