MathForge (a superb maths blog, worth subscribing to its newsfeed) claims that people all over the world are celebrating Pi Day since today is 3/14 which consists of the first 3 digits of the decimal expansion of . Not in the UK and other countries where the date is 14/3.
I propose an [i]e[/i] day to be celebrated on 2nd July all over the world

In fact on this side of the pond we celebrate pi day on the 22nd of July. Approximately.
Why is 157 an interesting number? The Guardian’s FE diary More than a number is not the sort of place where you would expect to find the answer. Let’s have more of this!
Thanks to Gooseania (who got it from Blog of a Math Teacher) for linking to The Sarong Theorem Archive. Just shows that blackboards still exist; they have completely vanished from FE and schools in the UK to be replaced by whiteboards or smartboards.
The problem is that whiteboards need regular proper cleaning and decent pens; smartboards are useless for maths since they are usually far too small and are too dependent on technology. I don’t miss the chalk dust but there’s little to beat a decent blackboard for flexibility.
