 OT: The Tau ManifestoMessage #1 Posted by Howard Owen on 27 July 2011, 12:51 p.m. "If you were still a [Pi] partisan at the beginning of this section, your head has now exploded. "

 Re: OT: The Tau ManifestoMessage #2 Posted by Crawl on 27 July 2011, 3:14 p.m.,in response to message #1 by Howard Owen I was half-way to being convinced before I even read that article. After all, pi is the ratio between circumference and diameter, but how often do we use *diameter* in equations? We always use radius. And the "prettiest" formula with pi, as he himself mentions, is pi*r^2 which, again, uses radius, not diameter.

 Re: OT: The Tau ManifestoMessage #3 Posted by Gerson W. Barbosa on 27 July 2011, 3:51 p.m.,in response to message #2 by Crawl 3:14 p.m. Does this mean some resistance? :-)

 Re: OT: The Tau ManifestoMessage #4 Posted by Csaba Tizedes (Hungary) on 28 July 2011, 3:21 a.m.,in response to message #2 by Crawl Err... The radius is not measurable. No one science will be lives without applications and experiments - and all theories in all science fields based on measuring. The diameter is MORE acceptable than a "theoretically founded" distance, like radius. BTW I'm a mechanical engineer :P :)

 Re: OT: The Tau ManifestoMessage #5 Posted by Gerson W. Barbosa on 27 July 2011, 3:45 p.m.,in response to message #1 by Howard Owen I quite agreed with the idea when I first read about it some years ago but I disliked the proposed symbol. The new symbol (pi without one leg rather than with an extra one) is definitely a better choice. Incidentally the Portuguese word for lathe is torno, which makes sense since it's a turning tool. A bit late for Tau Day, anyway here is the first pandigital approximation to tau :-) `sqrt(sqrt(51432/((6*7-9)*8^0)))`

 Re: OT: The Tau ManifestoMessage #6 Posted by Paul Dale on 27 July 2011, 6:02 p.m.,in response to message #1 by Howard Owen The PI Menifesto has a less rabid and one-sided view of the cases for and against both. Well worth the read. - Pauli

 Re: OT: The Tau ManifestoMessage #7 Posted by Gerson W. Barbosa on 27 July 2011, 6:28 p.m.,in response to message #6 by Paul Dale Conclusion: tau is a lame pi :-)

 Re: OT: The Tau ManifestoMessage #8 Posted by Howard Owen on 27 July 2011, 10:22 p.m.,in response to message #7 by Gerson W. Barbosa Yet another geometric argument for the primacy of pi. It would seem the Tauists have only one leg to stand on!
