Testa att mäta. Välj ut något som har en cirkels form. Mät först diametern på cirkeln. Därefter mäter du cirkelns omkrets och kollar hur många av diameterns

Den magiska konstanten Pi är förhållandet mellan en cirkels omkrets och dess diameter. Men vad händer om pi inte är det bästa sättet? Följ med Vi Harts 

Tau is fundamentally simpler. Radius is more fundamental than diameter, the fundamental constant should be based on radius. The Tau Manifesto is dedicated to the proposition that the proper response to “ π is wrong” is “No, really .”. And the true circle constant deserves a proper name. As you may have guessed by now, The Tau Manifesto proposes that this name should be the Greek letter τ (tau): τ ≡ C r = 6.283185307179586…. what I want to do in this video is revisit a little bit of what we know about PI and really how we measure angles and radians and then think about whether PI is necessarily the best number to be paying attention to so let's think of a little bit about what I just said so pi we know is defined and I'll write defined as an as a triple equal sign I guess you could call it that way pi is defined I mean, Tau is just 2*Pi. Er, Pi is just Tau/2.

428 views 2017-12-09 · Pi is equal to the area divided by the radius squared, whereas to gain tau, this number has to then be multiplied by two, again a waste of time and effort. Areas are the strong point for pi, if you have a unit circle the area will be pi, half its area pi/2, a hundredth pi/100 and so on, whereas when tau is used all these numbers need halving(giving tau/2, tau/4, and tau/200 respectively), a far less logical system. 2011-08-01 · Using tau, the angles around the circle are fractions of how far around the circle the angle is. If the pie-eater asks for an eighth of the pie, the pie-cutter goes τ/8 around the pie. Simple. Except we currently ask her to go pi/4 to cut pie/8. Which is to say that there’s a mismatch between the syntactic pi and the semantic pie.

Pi and tau

At its heart, pi refers to a semicircle, whereas tau refers to the circle in its entirety. Mathematician and poet Mike Keith once wrote a 10,000 word poem dedicated to the first 10,000 digits of

what I want to do in this video is revisit a little bit of what we know about PI and really how we measure angles and radians and then think about whether PI is necessarily the best number to be paying attention to so let's think of a little bit about what I just said so pi we know is defined and I'll write defined as an as a triple equal sign I guess you could call it that way pi is defined as the ratio of a circumference of a circle to its diameter which is the same thing as the ratio of

Tau is fundamentally simpler. Radius is more fundamental than diameter, the fundamental constant should be based on radius. Radians finally make sense, it goes against intuition to have 2 Pi radians in a circle. Pi is off by a factor of 2. The idea is that with 2 pi, errors can be made as sometimes the users forget the 2 whereas if it just one factor which is tau, errors can be reduced.
