Two signs of the times though:
No great fleet of OB vehicles parked outside - all to be seen were a couple of electric vehicles attached to fancy recharging posts (nothing to do with the lectures). It was all done as a temporary rig in an ante-room to the lecture theatre.
No longer do the RI lectures occupy a peak position in the EPG. They moved from the BBC some years back, to I think Channel 4 then five: now they're to be found on more4 - and of course on the web. At least the programmes are still available somewhere - I'd imagine it's not the easiest of productions to place, or even to produce. To my eyes there's been a growing disconnect between the pace of science demonstrations to a live audience and the current look of TV - it's possible to bridge between the two, but with more money than I suspect would ever be available to educational TV.
Taking up the challenge this year is furnacetv - and, I was pleased to see on my chance visit, a colleague of mine from long ago, Paul Sen, is producing. TXs begin tomorrow - Monday 21st Dec. Set your PVRs to series record because you've got another appointment - see the next mailing!
