Fulltime freelance provider of outreach and enhancement in maths ... I talk a lot. About maths.

I talk about other stuff too, like ballroom dancing, juggling, unicycling, education, engineering, software, and "other things".

But mostly about maths.

I tend to follow back, but only if you have something in your profile.
