At 6:28 (tau minutes), the score spells out the first four decimal digits of pi.

I say we use Pau, which is 1.5 pi or 3/4 tau.

[bobyrd]

is this the maths version of a rap battle?

[TackerTacker]

TAU makes 100% sense

PI makes 50%*2 sense

[MikeM]

I'm confident we can all adopt tau as quickly as the US adopts the metric system.

[uzairm]

Matt got 1 point for saying "wow"

[yujiokitani]

in that case divide it by 360


no one would use that kind of a unit.

[fernmendiz]

i love how they just switch to the base 12 system at the end because both Steve and Matt were like "Yeah, that's better"

[chrlokk]

2Pi or not 2Pi... That's the question...

[specialbuilder]

2 points for "historically, we've slaughtered goats" is my favorite

[zerid]

This is ridiculous. What would we bake on tau day ? :p

[abcddd]

The integration thing was really cool. so many physics formulas are 0.5*something*something else ^2 and its nice to preserve that pattern

[Mikeontube]

"Tau gets you nowhere." - 7:27 absolutely loving this!

[oliverpackham]

This video completely changed my view. I'm team tau now. I never thought of the fact that 1/x of a circle was tau/x radians.

[tgwnn]

when Matt said "the unit shouldn't be the whole thing" his score should've been halved...

[skydivertyler]

Why does τ only have one "leg" and π has two "legs" when τ=2π? Can we please switch the symbols?

[BoldFaceSeven]

*23 - 27*

"There are more advantages if we switch to base 12, than if we switched to tau"

*ding*
*1E - 23*

Why does one have to be better, this is like arguing "8 is better than 4 because most of the time, instead of writing 2x4, you can just write 8." and the rebuttal is "Well, what if you want to write 2+2=4, then it would be awkward to write 2+2=8/2" yes, yes it would, and that's why we have both.

[NoriMori]

I love how they got some of their points just for delivering sick burns. XD

[nataliesteffen]

I had a really hard time understanding radians and getting an intuition for angles in radians in terms of pi. Once I heard it explained in terms of tau, I understood instantly. Pi totally screwed me learning trig in high school.
