A couple of interesting videos are out on ted.com this week:
In the first, Sam Harris argues that science can answer moral questions, shaping human values and setting out what constitutes a good life. See here for Open Parachute’s take on this talk.
And in the second, Tim Berners-Lee (creator of the world wide web) demonstrates what can be achieved when scientists, governments and institutions make their data publicly available on the web. He mostly talks about mapping applications and it was particularly impressive to see how quickly publicly available map data was used in the aftermath of the Haiti earthquake.
