Eugenia Cheng is at it again

cheng pizza studyDr Eugenia Cheng, category theorist, has accepted some money from Pizza Express in return for writing some nonsense about pizzas.

This doesn’t really merit a post here, apart from to point out that Dr Cheng very scrupulously denied taking any kind of payment the last time she got a “formula for the perfect X” story in the papers, linked to a clotted cream company.

Toast formula

ACHTUNG: This post contains no information which could progress humanity’s understanding of the universe it inhabits. It contains links to several terrible newspapers. I have not fixed any of the issues in the source material, typographical, mathematical, grammatical, or otherwise. We are about to plumb the depths of innumeracy and inanity; consider yourself warned.

The Manchester Evening News published a story a few days ago with this unusual headline:  “(-Rav)/ t = R: Manchester boffins find formula for why toast lands butter side down”. Maybe the w (or ω) was present in the print version. Anyway, the article hits most of the bad formula reporting points: poorly typeset formula in headline; no explanation of variables; no link to the paper or the researchers; use of the word “boffins”; use of the phrase “infuriated puzzled scientists for more than a century”; formula invented to promote a product.

‘Maths whizz’ ‘predicts’ Grand National ‘winner’

Cambridge News is reporting that “maths whizz” and Cambridge maths masters graduate1 William Hartston has devised a system for predicting the winner at the Grand National on Saturday. Apparently he “looked at the number of letters in a horse’s name and the name’s first letter, the number of words the name contains and the horse’s age”. His system scores horses on a scale of up to 16 points; horses with one-word names beginning with the letters S, R, M or C and consisting of eight or 10 letters score well. The system apparently also takes age into account, which seems reasonable, but not the many other factors you might expect.

Hartston is quoted saying that Seabass is favourite to win as “the only horse with consistently high scores across all four criteria as it begins with S, is a one-word name, aged 10 years and has seven letters which is only slightly short of the preferred eight”. In fact, two horses scored 13 points, but Seabass has been chosen over Tatenen due to the mysterious claim “the latter’s scoring pattern was not as consistent as that of the former”. I’m unsure if this means that Tatenen’s name has changed.

And the work was “commissioned” by William Hill.

So far, so nonsense formula based on spurious correlations, but is that all there is to it? I always find it hard to believe that these stories are written or published, but there is something about Hartston as a source that seems especially strange.

  1. I particularly like how Click Liverpool has: “A “Master of Maths” has developed a formula…” as though “Master of Maths” is a made up thing. []

All Squared, Number 2 – Pancake formula

Here’s the second edition of our new podcast, All Squared. This time we talked to Dr Andrew Taylor, PhD, about nonsense formulas in the news. In particular, since we recorded very close to pancake day, we took a close look at the various “formulas for the perfect pancake” printed in UK newspapers.
