Micah 6:8
Job 26:6-14
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?
Today, 28 June (in normal US format 6-28) is Tau Day. eta beta pi
In 2001, Bob Palais published π Is Wrong,
where he said pi (π) should not be used for the circle constant—the
geometry of a circle expressed in a single number. Instead, he called
for tau (τ), which is equal to 2π, or roughly 6.28318, to be used
instead. Then, on June 28, 2010, Michael Hartl published the Tau Manifesto, which
stood behind Palais and expanded on his ideas. Like Palais, he called
for tau to replace pi, saying pi is a "confusing and unnatural choice
for the circle constant." He believed tau is a better way to describe
the relationship between the circumference and the radius of a circle.
With the release of his manifesto, he also created Tau Day. Just as 3/14
is Pi Day,
6/28 became Tau Day.
It is claimed that, for some unfathomable reason, a growing number of
mathematicians and physicists agree tau should replace pi, although they also admit that this
is not yet widely accepted.
If tau makes so much more sense, why hasn't it been widely accepted? I'll tell you why. Because it doesn't make more sense - they're just plain wrong. Looking only at the circumference (perimeter) of the circle and the diameter might, just might, make one think tau made sense. However, when one looks to the area of a circle, tau is much more cumbersome than pi. The circumference is 2πR, the area is πR² - using τ instead says the circumference is τR, but the area is now (τR²)/2.Why would anyone want to move to that?
Keep Calm and Don't Stay Away.
I'll be back tomorrow.
