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. ▼ Gerson W.

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 :) Gerson W.

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)))` Paul Dale Posting Freak Posts: 3,229 Threads: 42 Joined: Jul 2006 07-27-2011, 06:02 PM The PI Menifesto has a less rabid and one-sided view of the cases for and against both. Well worth the read. - Pauli ▼ Gerson W.

It would seem the Tauists have only one leg to stand on! Egan Ford Posting Freak Posts: 1,619 Threads: 147 Joined: May 2006 07-27-2011, 06:44 PM Thank you Paul. You made my day.
