I'm old. I get confused. OK?

That's going the wrong way.

comment what does $-2^2$ evaluate to?
Actually, the C-based languages do not have an exponentiation operator, but use functions instead, so there would be no ambiguity. Fortran uses ** but it places that ahead of negation in precedence, and I would imagine that other languages styled after Fortran use the same precedence.

comment Really simple question about sine wave equation with $\pi$
Yep, assuming t is seconds, this is an equation for a sinusoidal waveform of 150Hz.

@J.M -- I can't believe that I screwed up the title that badly!! I generally check spelling/wording over pretty closely, but after fixing the second "elipse" => "ellipse" I didn't look for the first, and the extra "d" must have fallen from the sky.

OK, thanks. I suspected as much, but my math is weak enough that I wasn't sure. And your diagram very nicely illustrates how it breaks down.

@J.M. -- Yep, essentially that kind of router. A collar would be fastened either to the base or to the shaft of the bit to hold the bit a fixed distance from the template edge.

comment Is there at least one irrational number with the property that it cannot be defined by a finite string of information?
(Got to thinking about it and realized my second statement above was wrong, in the most general sense. With a circular number line (what's the technical term?) you could have a finite number of orderable numbers and still not be able to identify one of them.)

I would observe that if there is such a number there's got to be more than one. And, if a finite number, they must somehow be unorderable (if that makes any sense at all).
