So that must mean I've been a mathematician since 2005?

This is a rather atrocious article giving yet another ad hoc "formula" to compute some numeric measurement of something-or-other. In this particular case, it's about cleavage, and how to avoid showing too much of it, but these "formulae" plague us every time some journalist wants to math up their reporting.

What caught my eye in this particular case was the people they lined up to back up the story.

Mathematician William Hartston, who holds an MA in Maths from Cambridge University, reckons this will save a lot of showbiz blushes on the red carpet.
