Break the Science Barrier is a television documentary written and presented by Richard Dawkins, which promotes the viewpoint that scientific endeavour is not only useful, but also intellectually stimulating and exciting. Featuring interviews with many well-known figures from the world of science and beyond, it was originally broadcast on Channel 4 in the United Kingdom - the first of a series of collaborations between Dawkins and the station - before being released on DVD more than a decade later. The documentary contains many of the themes later expounded in his book Unweaving the Rainbow, which was published two years after the initial broadcast.
