Skip to comments.'Tau day' marked by opponents of maths constant pi
Posted on 06/28/2011 7:09:39 PM PDT by decimon
The mathematical constant pi is under threat from a group of detractors who will be marking "Tau Day" on Tuesday.
Tau Day revellers suggest a constant called tau should take its place: twice as large as pi, or about 6.28 - hence the 28 June celebration.
Tau proponents say that for many problems in maths, tau makes more sense and makes calculations easier.
Not all fans of maths agree, however, and pi's rich history means it will be a difficult number to unseat.
"I like to describe myself as the world's leading anti-pi propagandist," said Michael Hartl, an educator and former theoretical physicist.
"When I say pi is wrong, it doesn't have any flaws in its definition - it is what you think it is, a ratio of circumference to diameter. But circles are not about diameters, they're about radii; circles are the set of all the points a given distance - a radius - from the centre," Dr Hartl explained to BBC News.
"What's amazing is the 'conversion experience': people find themselves almost violently angry at pi. They feel like they've been lied to their whole lives, so it's amazing how many people express their displeasure with pi in the strongest possible terms - often involving profanity.
"I don't condone any actual violence - that would be really bizarre, wouldn't it?"

When I’m hex four zero ?
Didn’t Newton devote the rest of his life to Biblical studies?
At least the Greek word pe’rime’tros began with the letter pi. Has this fellow bothered to look up any relevant Greek words that begin with tau?
All fun and games aside, I have noticed a tendency to make mathematics and science as counterintuitive and overcomplicated as possible, rather than explain things simply, For a culture whose very navigation is based on degrees, radians would be an unnecessary complexity.
But how will you know for sure that is really IS the last
stick if you continue to wallow in your pathetic obsolete
I propose a new unit called the dolt. 1 dolt equals 28 kilobidens. 1 square biden equals 1 obamadon. 1 obamadon equals 10^-8 erg-pelosi.
But only if you Kerry the Zero.
After Newton left Cambridge and moved to London, he did spend a lot of time on theology. He also spent a lot of time on alchemy. He wanted to turn lead into gold. As Director of the Mint for the English crown, it was Newton's job to look after the government's gold. In that job, turing lead into gold would have been a neat trick.
Plus they were a constant.
I thought it was 1 Biden = 28 Kilodolts.
I’m such a geek, I used to test my calculator’s capacity by making it figure out factorials. The highest it would go was 69 factorial. When I got my first computer, I would test how high it could figure them. I would type in 1000 factorial. It would begin the calculation, then a minute later pop up and say: “this calculation will take time, do you want to continue?” of course I said yes. I was so bored one day at work I figured out just how high it would go. Somewhere around 5000 IIRC. And it took a looong time. I don’t remember the result, but it was 10 to the some unimaginable power.
Once you get used to radians, degrees are unwieldy. I'm filing this story with all those metric-vs-imperial articles. It's a bit silly and has the same flavor. Metric is for idiots who freak out when they have to divide by 12. They can't do it without making a mistake. You should never give such people calculators or the metric system. They need to drill and practice, practice, practice their arithmetic.
What say you, Ultra? You’re the Math Master here...
As defined, Tau = 2 * Pi
Likewise, Pi = Tau / 2
In the end, it really doesn’t make a difference in terms of calculations.
