ab: Summary: The authors enthused by the seemingly simple ‘napkin problem’.
This might be described as a result of unintended consequences.
Allowing oneself to be side-tracked is something time often will not
‘allow’, but on occasions curiosity overcomes the ‘time’ demon.
Here is a well-documented account of following a mathematics byway
because it was interesting. Post Conference 2013 the intrigue continued
through an inset session, and beyond. You might need to have some
square paper napkins to hand as you read the account, which might
provide a new take on the term ‘absorbent’when applied to the
humble napkin.
