My Grade 12 class have looked at this story before, and now we can hear about it from Willie Smitts, a primatologist and conservationist who has led a huge project to replant and revive a section on rainforest in Borneo. They have taken over 8,000 hectares of scorched and cleared land and are returning it to a habitat worthy of orang-utans and many more endangered species.
Smits was featured in TED2009 and here he is with his story of how they regrew the rainforest.
On the heels of the NewScientist YouTube channel we have the offering from Nature. Where NewScientist provides a news-style clip of current Science headlines, Nature’s YouTube channel takes the approach of a video background to articles published in their journal. So far they have ten videos, though they provide useful background to articles such as the Antikythera mechanism, whale evolution and this one on sequencing the platypus genome:
It’s an encouraging trend to see these journals reach out into internet video publishing – cheap, easy and a great starting place for students getting involved in science. Let’s hope Nature can keep their channel going longer than ScientificAmerican, who started strongly but seem to have given up.
Another great channel (though not on YouTube) is the Journal of Visualised Experiments – actually publishing scientific research papers as videos. A good idea, and some really effective videos – especially for letting us see what is going on in the experiment or operation. Unfortunately, their videos can’t be embedded, so get yourself on over there and have a look.
As you can see in the NewScientist video, it was an example of a mechanical computer – designed to predict the relative positions of the planets, chart astrology and count down to the Olympics.It shows us just how advanced Greek science was, and makes us wonder – what would have happened if this technology had not been lost? Would the Greeks have been playing Spore in 200AD?
Some questions to think about:
– What makes this a computer?
– What sets it apart from an old alarm clock?
– Where do you think we would be now if this knowledge hadn’t been lost?
