Heard an interesting incident on Radio 4 yesterday morning. They brought on a guy who was a typical arm chair scientist and was insisting that the BBC series 'Walking with dinosaurs' was completely impossible because it was clear to anyone that dinosaurs couldn't possibly support their own weight. He said that much of the land must have been flooded which would allow them to live without having to support all of their massive bulk. They let him talk for a couple of minutes on this to put across his point.
So to counter this they got in paleontologist from the natural history museum in London who said that this was the opinion of scientists in the 60s, but if he had read the literature he would have seen the evidence for dinosaurs being able to support their own weight. The science done over the past 40 years had conclusively proved that even the largest of dinosaurs had the bone and muscle structure needed to allow them to move around.
It was a classic put down (in a single sentence) of a typical arm chair scientist that hasn't done any research and has come to his own conclusions about things. I'm not quite sure what BBC Radio 4 was trying to do here, but it was definately an interesting exchange.
Perhaps they should do the same with homeopathy?
