Don't Touch My Pi, Redux - 22 July 2021 - Plague Journal Day 497

Micah 6:8
Acts 28:12-14
Yes, your life matters.

We all are still sheltering in place, but I'm here to keep you sane and entertained.
One could hardly ask for much more than that, now could one?

If you are a regular reader here, you may remember my post of 28 June admonishing mathematicians to stick with Pi rather than move to Tau. Today, 22 July - 22/7 after the date-writing manner of most of the world - is Pi Approximation Day! (it's also known as Casual Pi Day - I like that notion) 

You may recall using 22/7 as an approximation for Pi when doing geometry back in your school days - I know I do.

This, then, is yet another reason to avoid Tau and stick with Pi - how could we ever get a day for Tau Approximation Day? That would have to happen on 44/7! (for the calendrically challenged among us, July only has 31 days - there is no 44 July - we would have to celebrate on 13 August and pretend. Granted, Pi (and Tau) is irrational (in fact transcendental), but it's not imaginary!


The very motion of the Earth around the Sun and of the Moon around the Earth militate against Tau. Just stop it!

Keep Calm and Don't Stay Away.
I'll be back tomorrow.
