For much of the world, today is Mother's Day!

Is it really possible to mix something as geeky, like memory and math, with the beauty of Mother's Day? You'll find out in today's snippets.

• If you have a geeky heart, you're mother is at least partially responsible. Since she helped give you a geeky heart, why not return the favor? Over at Math Jokes 4 Mathy Folks, one mom shows you how to make a magic square heart. Long time Grey Matters readers and Scam School fans may recognize the magic square principle used to create the heart.

• Maybe your mother likes music? In the video below, Vi Hart plays with mathematical symmetry groups, and gives them a surprising musical twist:



• Perhaps you're giving your mom flowers or plants for Mother's Day? Vi Hart has you covered there, as well. She posted a video series she dubbed Doodling in Math: Spirals, Fibonacci, and Being a Plant. Part 1 is here, followed by Part 2 and Part 3.

• Speaking of music, many people take their mothers out to see musicals for Mother's Day. One classic musical is The Pirates of Penzance, whose best known (and most parodied) song is the Modern Major-General's Song. Even if you're not familiar with the original, you've probably heard it as Tom Lehrer's The Elements, or in some other form. Recently, XKCD took its turn at parodying the song, calling their version Every Major's Terrible. It didn't take long before homemade music video versions of this song flooded YouTube.

• Once again, treat your mother right for Mother's Day. Think of all the times she's taken care of you, even when you were sick:



Happy Mother's Day!
