We accept that science (unlike religion, say) is a rational, objective search for verifiable truth. It is not subject to orthodoxy
In this 2006 book, physicist/cosmologist Lee Smolin argues that this is no longer so. It has become virtually impossible for researchers to get funding for novel research. A small number of approaches (e.g. string theory) are the established orthodoxy of modern physics and to stray outside these is to invite ridicule and exclusion. This, despite the fact that these approaches are still at the speculative stage and not yet verified (indeed some are unlikely to be verifiable). Smolin makes the point that physics has not had a significant breakthrough in 30 years (and that was 12 years ago). The true scientific approach has been subverted by a new brand of dominant and dogmatic high priests.
The book created something of a storm across the wider scientific community in many other branches of science where the same limitations have come to apply.
Smolin writes well and accessibly, an interesting and thought-provoking read which cautions against assumptions that science is objective and free from orthodoxy
