Re: This is exactly the problem
There's a lot of truth in what you say - The BBC (or for that matter other channels) hardly ever deal with Science/Technology on its own terms. It has to be dumbed down or jazzed up to make it "appealing". Contrast this with, for example, Radio 3 CD Review ( which I like ). For 3hrs every Saturday morning on a main national channel music is discussed, analysed and illustrated at length using sometimes technical but still accessible terms for those that want to listen.
'Codes that changed' the world was a partly flawed step in the right direction, but given the plethora of Radio and TV channels now available, when will some broadcaster have the courage to start doing 'real' science/technlogy programs that really appeal to and inform the millions who work in or study such subjects.
