Further to the previous post: Prof Callaghan has sent me a couple of links that you might like to follow. They're both for streamed & downloadable videos.
The first one is a lecture he gave round the country in December last year: Beyond the farm & the theme park. And the second link is to a TV series that he's fronting on the same topic - the idea that we need to look at expanding our investment in high-end value-added science & technology: Paul Callaghan presents.
See what you think. I haven't watched all of the video series yet, but I found the December lecture stimulating & thought-provoking.
