Last week we hoped you celebrated “Tau day” – 28 June. The clue is in the date (6/28), as Tau is twice pi (whose day, as we have previously recorded, ought to be celebrated on April 31 by the same system).
Tau, for all you mathematicians, makes the algebra easier in some equations, because they often end up with twice pi being squared and cuberooted.
The BBC interviewed “the world’s leading anti-pi propagandist,” former theoretical physicist Micheal Hartl, and published a picture of a pie.
Commenters luckily took the subject more seriously, one even pointing out that using tau messes up the equation e^(i x pi) +1 = 0. The rest of the world sighed and shook its head sadly.
Still, there’s always e-day to look forward to, on 71 February.
