OMINOUS CLOUDS GATHER: hear's watt ewe knead two, no?
I was thinking.
Pi has apparently been computed to 13.3 trillion digits, using the Madhava-Leibniz series; so it's apparently one of the universe's "built in" numbers. However, pi is also the ratio of a circle's circumference to its radius: has there ever been an experimental verification?
It shouldn't be that hard to experimentally verify pi, at least to a few hundred digits: we've got lasers, and it should be easy to build a big enough circle somewhere.
It might lead to interesting results: what if you discovered that empirical pi is different from mathematical pi? It could happen: all you would need is for space to be non-euclidean, right? And we already know it's non-euclidean: that comes straight out of relativity theory. So gravity would distort pi, so a circle laying on the ground would have a different ratio of circumference to radius than a circle lying on edge; but time would also distort pi at large enough distances, right?
Why the hell haven't scientists studied this yet?
Anyway, here's a bit of news:
New Deal Demoncrat - ominous clouds gather. Well, true, the housing sector is a big component of investment and thus a major determinant of recessions. So is a recession really coming in 2017? And if it is coming, can we please blame it on lunatic Republican governors and those idiot Germans?
Calculated Risk - FOMC projections.
WaPo - Fed lowers economic forecasts.
Weather Network - Clearly Canadian: BC crime suspect attempts to flee RCMP on an ice floe. Then she builds a fire on the ice floe.
