Mny of the best resources on the internet involve video-clips which unfortunately are not available in most schools.

One resource which is available is www.ted.com

As it says itself “Inspired talks by the worlds’ greatest thinkers and doers”. wonderful

Science and Astronomy talks are there, along with much, much more.

Many of these involve concepts which should be part and parcel of out students’ education, but because of the inertia involved in education will probably never appear on a syllabus until they in turn have become obsolete. If nothing else it’s nice to listen to a talk in the background while doing other work on the computer.

It “brings together the world’s most fascinating thinkers and doers, who are challenged to give the talk of their lives (in 18 minutes)”.  It tends to be the antithesis of our conventional educational system in that it encourages interdisciplinary links rather than pigeon-holing knowledge into autonomous subject areas.

This talk by James Watson of The Double Helix fame is a perfect example. We / I need to show these more often in class.
