Can you take a look at https://github.com/sympy/sympy/pull/1223 where
this is now corrected.

That's right, but you still can comment on your proposal(s), which
does give a bit of flexibility. (At least that's what I hope for :-)

Hi all,
sorry to bother you with such trivialities. It seems that the web.de
email system is experiencing some difficulties. I couldn't find anything
on the web about this, but for me it manifests in severely delayed or
outright lost (hard to tell the difference) messages.
As of this morning

Inertia dyadics are fixed to the frame they are originally defined in;
you cannot rotate a fixed vector/dyadic in its frame, but you can
rotate the frame they are fixed in relative to another frame. What you
can then do, for both dyadics and vectors, is express them in this
different rotated frame.

Yeah, though the ability to just download and run the bot is nice.
Given Python's dynamic nature, it should be possible to detect whether
the logging library is available, and to log to stdout if it is

Totally right.

Therefore, if a ring is unital by definition, I maintain that no
inheritance should be introduced between Ring and Ideal.
I concur.
