If you have nothing to say other than "it doesn't matter," why do you care enough to even comment on the debate? Neither side would capitulate, so they went with 48 bytes, which is worse than either for both sides.
However, Grey Matters is not about me. Most people know π (pi) by the approximation 3.14, but do not know τ (tau) which, by definition, is twice as large as pi. Of course, regardless of which convention is used, the change is merely in notation — the underlying mathematics remains unaltered. The explainxkcd for 287 says nothing about floating point. Tau is a constant equal to 2 * Pi. Personally, given my last name (Furlong), which is defined to be 1/8 of a mile and is most often encountered in horse racing, I think that kappa = tau/8 = pi/4 = eta/2 = 0.7853398163397448... would be another fine choice for a fundamental transcendental constant number if for no other reason than that kappa is the first Greek letter in the Greek word for a circle, kuklos! Shop high-quality unique Tau T-Shirts designed and sold by artists. This Mathematica code searches for the pattern 666 in the octal expansion of 1.5 pi: These positions start counting with the leading "4" as position 1. I find this discussion to be utterly fascinating!
The Tau Manifesto itself is also available on the site for free. \(\tau\) got 40.9% of the votes and \(\pi\) only 36.4%.
Pi. The following video, The Story of Pi, is a great refresher course on a very useful constant:
. The appearences of the extra factor of 2 comes that Kodegadulo sees from two different sources. Maybe with a deformed left leg? zN is a sixtywise number. We could call these units diameterians, which would be equal to 2 radians. Popular culture may be making it a reality the same way made up words become socially acceptable according to dictionary writers. Here, k = pi/2. Normally one argues about which one is more natural or easier to use. = \frac{2 \eta^4 D^8}{7 \cdot 5 \cdot 3} \], \[\frac{\eta^4 D^9}{9!!} It is easy to understand …
If you need a refresher, here's a clear and simple Unit Circle tutorial. = \frac{2 \eta^2 D^4}{3}\], \[\frac{\eta^2 D^5}{5!!} Explain why the Wolfram Alpha answer is different. And out of curiosity, what happened with 287 and floating point numbers? (Live is live :D). = \frac{\eta^3 D^5}{4}\], \[\frac{2 \eta^4 D^7}{6!!}
Possibly, Randall used Wolfram|Alpha to calculate the result (he uses it a lot, for example What-if 70: The Constant Groundskeeper or What-if 62: Falling With Helium). That only leaves us π Day being on March 14th (3/14) and τ Day being on June 28 (6/28) is well and good, but when would we celebrate η Day?
= \frac{\eta D^3}{3}\], \[\frac{\tau^2 r^3}{2!!} math, = \frac{\eta^3 D^7}{7 \cdot 5 \cdot 3}\], \[\frac{\tau^4 r^7}{6!!} In the system of Greek numerals, it has a value of 80.Letters that came from it include the Roman P and Cyrillic П.. The method I used to get the value I put in the text was; I used the following command to generate my approximation: 4.554574376314416443236234514475050122425471573015650314763354527003043167712611655054674757031331252340351471657646433317273112431020107644727072362457372164022043765215506554422014311615574251563446213636251744101107770257, In 'bc, a(1) is arctangent of 1 (i.e.
Both Maxima and the GNU Emacs calculator output as the first 1000 octal digits: This also agrees with the first 220 digits of the previous result (last two digits above are 57 vs 61 here, maybe due to rounding when converting to octal). Trigonometrically, sin(kappa) = cos(kappa), uniquely, and kappa is the unique angle any diagonal of a square makes with the sides of the square! = 2 \tau r^2\], \[\frac{2 \tau^1 r^3}{3!!} We will be playing soccer, ultimate frisbee, and/or capture the flag at, - if you placed an order a while ago, you put a size down in respects to the, Polos are 50/50 cotton and polyester blend, all black, and has a bunch of different features with the fabric. But it'll probably never change, so pi'll have to do.
But for geometric ratios (which these are), the appropriate mean is generally the geometric mean (hence the name). Others consider proponents of tau to be foolish and remain loyal to pi (see the Pi Manifesto). Should we still use degrees instead of radians and Roman numerals instead of base 10 just because they "reflect the long history of mathematics"? Again, no 666 within the first 200 digits.
108.162.218.41 21:41, 31 May 2014 (UTC), Is it worth mentioning that while Tau simplifies circumference calculations from 2*pi*r to tau*r, that it complicates area calculations from pi*r^2 to tau/2*r^2? New Tables!
Pau is somewhat less conveniently, but more accurately, approximated as (401-sqrt(2)*phi)/200. around again. Are you a Junior or Senior mechanical engineering student in the top 25% of your class with a minimum cumulative GPA of 3.25, or a graduate mechanical engineering student ... , PTS and ASCE will be hosting Sport Day event. = \frac{\tau^3 r^6}{6 \cdot 4 \cdot 2}\], \[\frac{2 \tau^3 r^6}{5!!} Notwithstanding all the enchanting and intriguing arguments for tau and eta and kappa, I stay with the observation I started with, namely, that pi is here to stay supreme for quite a while, which makes my successful efforts at committing the first 1512 decimal digits of pi to memory seem slightly less ridiculous than they were! 173.245.54.86 09:21, 18 November 2013 (UTC). Eta is only the ratio of paths when the long path is a semicircle; when it is any other arc, eta doesn't work, so eta doesn't describe a circle at all that way. Bob Palais classic article π is Wrong! —TobyBartels (talk) 20:50, 18 November 2013 (UTC), I am in favour of just calling it ti(e). Grey Matters is my website. (ref: http://www.basketball-reference.com/players/g/gasolpa01.html ), to which neither Tau nor Pi can hold a candle.~~Remo ( 199.27.128.183 19:19, 18 November 2013 (UTC) ). You can see how even-handed this is: it's (√2)π = τ/(√2). Today is 6/28, making it Tau Day! Like geometry, which literally means 'land measurement,' shows how today's complex math comes from Greek farmers trying to plot out fields efficiently. What is involved is the concept of bases other than base 10, specifically octal, but that is also a secondary school subject, both in mathematics and computer science. Pi (π) still equals the same infinite string of never-repeating digits. = \frac{2 \tau^4 r^8}{7 \cdot 5 \cdot 3}\], \[\frac{2 \tau^4 r^9}{9!!} --173.245.53.150 00:10, 23 November 2013 (UTC), The trivia that states that e here represents Euler's Constant, and not Euler's Number, seems to be false, is it not? = \frac{2 \eta^3 D^6}{5 \cdot 3}\], \[\frac{\eta^3 D^7}{7!!} The combination 241134 first occurs in 1.5 pi at digit number 250,745. And since when is advanced trig a college level course? The main reason is that the ‘tauists’ don’t get out into the real world all that much, and are facinated by mathematical tricks. Is it time to remove the Incomplete tag yet?
Coincidentally, e+2 is also very similar to 1.5 pi, although only to a few digits. Why not decide which one is more beautiful? Learning is always beneficial, but the Grey Matters philosophy is that learning can and should be fun. In fact this can be generalized to describe any multifactorial function: \[\begin{array}{ll} n!^{\left(k\right)} = \left\{ \begin{array}{ll} 1 & \
( PDF link) is also considered to be a must-read for Tau enthusiasts. = \frac{2 \tau^2 r^5}{5 \cdot 3}\], \[\frac{\eta^2 D^4}{4!!}
only work with radians. Oooh - I like that new word - thanks to repeating decimal! Americans wanted 32 bytes of data per cell, to support DS0 data rates, IIRC.
e+2 being ~4.71, not ~2.58.
Why did I stop at 1512? Upon Latinization, the Greek upsilon becomes the English "y" so that the etymology of "cycle" from kuklos is readily seen! Notice that even from the seemingly simple shape of a circle, we can look at it from so many different ways.

A few mathematicians argue as to whether to use pi, which is the ratio between a circle's circumference and its diameter, or tau, which is the ratio between a circle's circumference and its radius. David Butler's video shows the surprising uses of Eta, some of which rival Tau AND Pi! 141.101.97.4 07:07, 18 November 2013 (UTC), This number contains 7777, 000 and 444 twice, though. = \frac{\eta^2 D^4}{4 \cdot 2}\], \[\frac{2 \eta^2 D^4}{3!!} Explain octal -- base 8 -- first for integers, then for fractions.
There is always this debate \(\pi\) vs \(\tau\). Well, 1511 is the 240th prime number, there are 24 hours in a day, and 10 is the well-known and well-beloved base of our decimal system, and I couldn't properly round pi to 1511 decimal places without knowing the value of the 1512th decimal digit (which happens to be a 7, coincidentally the lucky number of days in a week, which causes the 1511th decimal digit, 8, to round up to 9, which also happens to be the 1510th decimal digit!) There is always this debate \(\pi\) vs \(\tau\). Maybe we can call this ‘ti’ (or ‘tie’, pace 173.245.53.184 below). I know it's easy to spot if you look at the start so please just enjoy it and vote without trying to consciously figure it out :), Okay I think we need to finally decide: Pi or Tau? I propose the following outline of the section: This wiki is about explanations. I think eta is really only useful when looking at right angles and not any other angles.
The results are in! If you take the output of octal(pi * 1.5) and paste it back into the input like so: Wolfram gives you back (converted to decimal): If you give that same input to BC and ask it to convert to decimal you get: If you do the math long hand out to 55 decimal places, pi * 1.5 equals: Converting that by hand into octal is a bit of a pain, but if you do, at the 18th decimal place where BC and Wolfram differ you end up with the following: Wolfram gives the 18th decimal as 5, BC as 3. No other run of 3 or more repeated digits (e.g. Please take a look around, explore, and enjoy! Btw it's published How to visualize numbers! Tau Day is an annual celebration of the circle constant $\tau = 6.283185\ldots$, which takes place every June 28 (6/28 in the American calendar system). It's not worth your time trying to understand the concepts here."? That's been part of the fun of putting up this post. I should try harder 625571b7-aa66-4f98-ac5c-92464cfb4ed8 (talk) 14:41, 14 March 2017 (UTC), http://www.basketball-reference.com/players/g/gasolpa01.html, I used Google News BEFORE it was clickbait, https://www.explainxkcd.com/wiki/index.php?title=1292:_Pi_vs._Tau&oldid=193354. If 200 were octal, that would be 128 decimal, so we would end up writing 128 decimals.
Keep it pi. = \frac{\eta D^2}{2}\], \[\frac{2 \eta^1 D^2}{1!!} η Diameterians? Tags: julia, luxor. Many other digit combinations occur more times in the first 10,000 digits, including "123" (23 times), "222" (21 times), and "555" (26 times). For a donation of a single dollar per month you get early access to the posts. Pi vs Tau. However, that advantage is lost in other dimensions and for the area of a circle.
