## Pi Day

Tuesday 14 March 2006 at 6:52 pm | In Articles | 1 CommentMathForge (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*

## Blackboards

Tuesday 14 March 2006 at 12:58 pm | In Articles | 1 CommentThanks 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.
