There's at least a few people I can think of who do the same sort of thing much better, there's the guy who did a show about Light on BBC 4, there's Jim who they put on the trolley on the show, there's the guy who used to present the Chemistry of almost everything.
And yes I agree 100% BBC science is dumb populist and uninteresting the likes of Richard Hammond Builds a Planet, Bang goes the Theory or Orbit does no-one any favours. I think it's a terrible shame they essentially killed off Horizon before it was dominated by to many medical stories that was good and so was Equinox (long since cancelled by Channel 4).
The biggest problem is they tell you what they are going to tell you - this normally takes a good 10 minutes then they tall you again or the background a little bit - but no real helpful info and then they give you a tiny bit of useful info in a conclusions and then proceed to effectively repeat the 1st 10 minutes and tell you what they just told you - any show formatted like that has me banging my head against the wall. Not to mention that they often repeat Myths about the history of science that are massively understated or in some cases just wrong - they attribute inventions to the wrong people or understate the role of individuals in a historical event.
For example how many people know that Herbert (HG) Welles may have started a series of events that lead directly to the development of Atomic weapons or how horribly misrepresented the discovery of DNA is on most TV shows.
I can honestly say that when they used to put programmes for schools or the Open University on they had better content and more educational value than most so called adult science did.
I liked that show with that attractive blonde stuck in a submarine/ crashed plane (from a few years back) aimed at kids of about 12 - That actually told you interesting stuff about things that you might know or you might not - but it was still worth hearing - I remember a very neat explanation about how water boils at a different rate and temperature depending on atmospheric pressure - Not something you think about much but it was explained in a non patronising way that was fun to watch - unlike the adult shows that are often a bit stupid. Not that I mind a bit of stupid now and again that Robert Lwelleyn show debunking Hollywood science was sort of fun.
