Nerdity ahead

Last night I discovered that during certain times of the month I can see the moon just outside my window while lying in bed. It was a waxing crescent last night, and it distracted me while I was going to sleep because I kept gazing at it.

I saw the class banners in Evans this morning thanks to Alumnae Weekend, and it made me think of class colors mod 4. (Basically, a number c is congruent to b mod 4 if 4 divides c-b. Basically, if there's some integer k so that 4k=c-b. So 16 is congruent to 0 mod 4, 47 is congruent to 3 mod 4, et cetera.) If we assume that the colors have always alternated yellow, red, green, blue, then the blue class years are congruent to 0 mod 4, yellow to 1 mod 4, red to 2 mod 4, and green to 3 mod 4. If we think of this mod 2, the 0 mod 2 classes are sisters and the 1 mod 2 classes are sisters.

Wow, I'm such a nerd.

I see that moon. ^_^

I have the feeling that even though I didn't understand that completely, I could if I wanted to....ah, but I chose to turn away from Math classes...

I'm coming to your astrophysics presentation and look forward to it!

Boo for turning away from math classes. But yay for coming to my presentation! I promise there will be very little brain pain.
