Yesterday, I attended a great presentation by Greg Asner at the School of Geography and the Environment (Oxf). He talked about this amazing project that uses cutting-edge technology to study ecological systems, biodiversity etc. The kind of work that makes census data and household surveys look like child toys.
He gave a similar presentation
though much shorter at TED Talks last year.
You may ask why I went to this presentation.. after all it's not much related to urban development, transport policies or demography. In the end, I think that some people are so good in what they do you can always learn something from them, no matter what their field of research/activity is. Besides, science is fun.
