Plus Advent Calendar Door #4: take a look at Numberphile!
The auspicious date of 11/11/11 saw the launch of a brand new YouTube channel dedicated entirely to numbers – Numberphile! They are producing two new videos every week (phew!) , each about a different number. So far they've covered 16, 11, 255 and 8128 and we have four new favourite numbers to thank for it. We can't wait to see what they do next!
