cardiod.jpgHappy Valentine’s Day! Are you a science geek too? Searching for your true life’s companion? Make sure he or she can grok your geeky little brain by sending them a card with this message. This is the mathematical equation for a cardioid in polar coordinates, which is a heart-shape.

You can find the full activity and description at Paul Doherty’s website. According to him, sending this Valentine’s Day card makes you a member of the Mathematics Mafia (defined as “an organization that makes you an offer that you can’t understand.”)

Or an even more satisfying heart can be made with a more complicated cardioid equation (from Mathematische Basteleien)
