Hans Rosling, professor of public health, speaker extraordinaire, software entrepreneur and one of the best illustrators of fact-based research and policy discussions I have ever seen, is now available in English from the TED conference.

See it. This is required viewing for anyone wanting to understand how the world evolves and what we need to do to make it evolve in a direction beneficial for all. Rosling is one of the best speakers I have ever seen, on any subject, and this subject is critically important.
