Correspondence

When an experiment changes my mind, I write a letter about it. There is no schedule, and each one asks you something back.

Write to me

I read everything that comes to this address, and I answer what I can.

Students: a question about a lesson, a course or where to start.
Fellows and researchers: an experiment that argues with mine, or one we could run together.
Practitioners: a problem from the field that a piece here touches.
Organisations and institutions: teaching, talks and research collaborations.

Replying to a piece? Put its title in the subject line; every piece ends with a link that does it for you.

No schedule. A letter goes out when an experiment changes my mind: what I keep, what I revise, what I test next, and one question back to you.
