The pi is a lie… Happy Half Tau Day!
This joke is starting to get pretty annoying..<p>There are lots of things we do for conventional reasons, such as having electrons exhibit negative charge.<p>If you're doing any actual complicated math or physics, the last thing you care about is having a different constant floating around in your terms.<p>What it is, however, is a great learning tool - This thing called pi, maybe we could get away with, or even be better off calling it 2pi. - Can get lots of people thinking about math and possibly learn something cool like trig. But when used in a psuedo intellectual way, it 'really grinds my gears'.
