J.L. Powell has crafted a very readable and compelling tale of geologic sleuthing, intrenched conventional wisdom, and the triumph of insight and determination in investigating one of geology's greatest puzzles - what killed the dinosaurs?
Should be mandatory reading for advanced high school/intro college courses in earth science. Should also be mandatory reading for every politician who blathers on about the significance of "consensus science", because that term is an oxymoron and leads to exquisitely wretched legislation. This book chronicles the contributions of "young Turks and outsiders" to the advancement of science.
In the end, the hypothesis that explains more of the facts wins out and moves the science forward - not the hypothesis that is accepted by the "vast majority" of specialists.
