Some of the most interesting stories in the history of science are those where investigations take a wrong turn. Scientific progress is filled with red herrings, failed assumptions, and wild guesses that rarely make it into the science textbooks. When I first started this blog, for instance, I talked about the ridiculous number of atomic models that were proposed before Rutherford finally discovered the atomic nucleus in 1910.
It’s a shame that these stories are often overlooked, because they can often tell us more about how science is done than the famous success stories can. And, as I said above, these failures are often fascinating, and in the hands of a great writer can be utterly compelling.
I was therefore really excited to read Thomas Levenson’s most recent book, The Hunt for Vulcan (2015):
The Hunt for Vulcan tells the curious story of how physicists and astronomers became convinced of the existence of a planet that orbits closer to the Sun than Mercury, a planet that never existed. The search for Vulcan would eventually lead to one of the greatest scientific discoveries in history: Einstein’s general theory of relativity, which unifies gravity with Einstein’s special theory of relativity and truly transformed our understanding of the universe as a whole. Along the way, there were personal squabbles among scientists, failed searches, mistaken discoveries, and a World War that altered the course of science.
