### Re: The Tau Manifesto

I guess my point is that if Pi had been properly defined in the beginning to be 6.28..., then, today, 3.141592... wouldn't have any other significance besides being half of the full circle. You can make all the excuses for Pi that you want, but all I see is you making excuses for something that was ...

### Re: The Tau Manifesto

When you integrate from 0 to pi, you are usually not doing "half" of something. Maybe an entire azimuth, for example. If anything, the more you talk about tau, the more resistant I get, because it seems like you are oblivious to the big picture. Instead of "it shows up all over,"...

### Re: The Tau Manifesto

It's not the same sort of argument, though, because pi advocates are suggesting keeping a convention while hypothetical & advocates would be recommending a whole new one. Personally, my resistance to tau is analogous to my resistance to proposed English spelling reforms and the like. Sure, refo...

### Re: The Tau Manifesto

Using tau/2 instead of pi in an integral only gives you more information about the range in those specific cases that come from something that goes around an actual whole circle. Which isn't always the case in the integrals I think doogly is talking about. That's a fair argument. But the point stil...

### Re: The Tau Manifesto

No, Pi literally means "the sixteenth letter of the Greek Alphabet, with sound [p]". In Mathematics, it also represents the ratio between a circle's cirumference and its diameter. You're making my case for me. It represents the ratio between a circle's circumference and its diameter. (Cir...

### Re: The Tau Manifesto

On the other hand, there are a lot of integrals you do from 0 to pi, and having to put tau/2 in the limit of an integral would not only take up the ink, it would force your font size down in what is already prime real estate. I guess my problem with this argument is that we don't have an issue with...

### Re: The Tau Manifesto

The test scores alone, if the difference is significant and replicable, show only that tau makes for a better introductory number to use when teaching plane geometry for the first time. That's nothing to scoff at, of course, but as korona pointed out above, pi shows up in a lot of places apart from...

### Re: The Tau Manifesto

oh my, I had almost thought that real mathematicians were involved, and then I investigated the first names that is not the notable Palais All 4 are mathematicians. Most of the naysayers I run across are non-mathematicians that like to troll forums. But it doesn't matter. The point is, it doesn't t...

### Re: The Tau Manifesto

I always use Tau now when working with angles and I teach it to all my students because it's so much more intuitive to work with. Sub in tau = 2pi right at the start and sub back at the end, voila 80% of high school radian mistakes disappear. I think the biggest increase in test scores was 40% but ...

I agree! I have no problem using Pi as long as the formulas use the diameter! Because then it makes sense! At least then you're using Pi paired with the thing it was derived from.

### Re: The Tau Manifesto

Ever since I read the Tau Manifesto, it's been eating at my brain. Everywhere I see Pi, I see the "what-if" scenario of Tau having been used instead. And every single time, it's more elegant and tells me something a little bit more about what's actually going on. Somehow I missed out on &q...

### Re: The Tau Manifesto

I think the thing to remember is that some guy at some point in time decided to assign 3.1415... to the Pi symbol. It soon caught on as a convention. Do you really think we'd be having this discussion today (about whether he made the right choice) if instead he assigned 6.2831... to Pi? I really don...

### Re: The Tau Manifesto

I am a recent convert to tau. The manifesto clicked with me immediately. Pi was derived in terms of diameter, yet diameter NEVER shows up in our equations. It's always the radius! If we used the diameter in our formulas, then Pi would be perfect! But instead we use the radius, so we have to have an ...

### Re: "Crossbows" Discussion

This may be a longshot, but sometimes we have to use a bit of lateral thinking for some of these comics to make sense. I believe there must be a link between the words bow and boson, perhaps a pun. By Tuesday, they were supposed to find the Higgs Boson particle. Option 1: something to do with gettin...
