Three is a magic number
As I lay not sleeping at three o’clock this morning, I drifted into that weird “Isn’t that cool?” state that one gets into when one isn’t really paying attention.
This morning, I was thinking how cool it is that 3 × 17 = 51. I mean, 51 doesn’t seem at first glance to be a multiple of anything. At least not to me. Then I started thinking about the trick to determine if a number is divisible by three, and I thought that was really cool, too. Then I thought about writing this post, and then I went to sleep.
