in the last few years tsan had regular weekly presenters who contributed more than sir patrick. i can see no reason why the show cannot continue with just these.
peter and paul, dr chris and other chris. they have a great mix of amateur and proff, with stuffiness and a dash of eccentricity. i can see sir patrick was a combnation of all four of them.
brian may would be a worthy contributor.
however i do not want to see brian cox. i see he is starting a natural history programme on the bbc now. how ridiculous. i get he is a decent physicist but that has nothing to do with biology.
are the bbc stupid?
