AS: Something like - I have to talk about one of the genetics ones. DNA workshop where - students extract DNA from their mouths and then use Polymerase chain reaction which I don't know if you've heard of or not but anyway what happens is they - you effectively photocopy the DNA so you end up with one particular piece of DNA that you keep copying and copying and copying so you end up with millions and millions and millions of pieces of that DNA. And then you can visualise the DNA by running it through a gel and at the end the students get really excited because they see DNA in a gel, you know. And you can see a hundred or a thousand pictures of DNA you know. Everyone's seen the DNA fingerprints for - you know, crime scenes or whatever. Not crime scenes but after they've taken the samples and run them out you'd see this DNA fingerprint. And - but to actually run it themselves and get an understanding of how how you actually end up. I mean what they have is not a DNA fingerprint but the principle is the same in terms of running DNA through a gel to separate it.
And that you know it's great. They've never done it before but they will absolutely go away from that workshop understanding - precisely how that technique - Polymerase chain reaction works. Which is a really clever reaction but it's not very easy to understand on paper. And when I I have to say, going back to that. When I was doing my first post-doc in Sydney I hadn't done any genetics at all because my PhD was in neurosciences. And as I said earlier - I think I said earlier that, oh I can't remember, in 1986 this particular thing was, was developed by someone called Kary Mullis. And so I hadn't even done it at college cause I left in 1985. So when I did my PhD at post-doc I didn't even know what they were talking about so I had to be taught it and I was taught on paper how it worked but it took me forever to try and think "ok, so that's the next step" whatever. If I'd have done the workshop that we have here I'd have learnt it like that ((snaps fingers)). And because we use an interactive model, we use computers and they actually do it themselves as well. So you know that is - I suppose it's more of a personal thing for me. It's not a particularly difficult concept but I think it's quite hard to explain.
