In today's live stream, we mentioned that today is Pi Day (3.14), and I (Andy) referenced Daniel Tammet. I was first introduced to Daniel watching him on David Letterman many years ago and was fascinated by his story, which led me to read his autobiography, "I Was Born on A Blue Day."
Daniel is a "Prodigious Savant" with Aspergers, and he claims an incredible ability to understand both numbers and languages.
As today is a rainy day, maybe a couple of short videos will amuse you (or your kids). At the link below, you can watch a short interview where he talks about memorizing Pi (bonus points to the first person responding with the number of places he memorized the number).
Here is a link to a video where he tells about learning the Icelandic language... in a week.
