Today is March 14, otherwise known as 3/14. For any math enthusiast, these numbers will certainly set off a bell — they are the first three digits of Pi. To help you celebrate Pi Day, here are two TED Talks, starting with Daniel Tammet’s “Different ways of knowing.” Tammet has linguistic, numerical and visual synesthesia — meaning that his perception of words, numbers and colors all blends together, giving him a unique experience of the world. Scoot to 4:46 to see his painting of Pi, rendered as an emotional landscape.
And while you’re at it, watch 9-year-old Chirag Singh’s adorable talk from TEDxYouth@BommerCanyon, “My passion for Pi.”
