I met Matthew Watkins in a field in Somerset, where he was sitting beneath a sign saying “Free Maths Information”. He’s a musicomathematical nomad (or is that a mathemusical itinerant?) with some interesting ideas about the connection between the distribution of prime numbers and fundamental physics. Maths pages here (includes many interesting side notes, such as this essay by Philip K Dick). Music pages here and here (and make sure you check this out). More Big Green pictures here.
