⬐ aylmaoHonestly should've been, Tau makes much more sense IMO (:⬐ umanwizardhttp://www.thepimanifesto.com/In my opinion, the most natural definition of pi is "the area of the unit circle", which would be tau/2.
⬐ Armisael16⬐ RickJWagnerIn my opinion, the most natural definition is the circumference of the unit circle, which is tau. The area of the unit circle is then simply the integral: tau/2*r^2.Start at the lowest dimensional property (1D).
Interesting! Articles like this make Hacker News stand out. Thanks, poster!⬐ zeristor⬐ joezydecoA simple rule is to post all videos by 3Blue1Brown to HNRead The Tau Manifesto!⬐ ballenfKind of ironic that the video makes a compelling argument why such arguments are wastes of energy and miss the point.For those who don't care to watch, the tl;dr is Euler used the constant symbol for pi similar to our use of theta, as a constant without a fixed value. Sometimes it was 3.14, sometimes 6.28 and sometimes pi/2, just depending on what problem he was solving and what form was most convenient.
The lesson being, don't get caught up wasting energy on the argument that could be used towards solving problems.
