What can be said at all can be said clearly, and what we cannot talk about we must pass over in silence. – Ludwig Wittgenstein

Driving about on various errands yesterday I found myself listening to ‘word of mouth’ a program about language presented by the excellent Michael Rosen.  This week was ‘silence’, and it started with a really interesting interview with a maths teacher on how he used it in his classroom, which wasn’t the stereotypical way one might expect.

It’s possible to listen again for a week, but unfortunately there’s no podcast.
