This is a slightly dramatised biography of Kristian Birkeland, the Norwegian physicist who first postulated an accurate explanation for the Northern Lights, and for whom Birkeland Currents are named. It was given to me by my Octothorpe co-host John Coxon after I asked him to explain his research to me.
Books of this kind sit on a scale between straight biography, with every assertion meticulously footnoted, and historical fiction. Jago's book is somewhere in the middle. It has no footnotes, and she has admitted some liberties, but she has not attempted to write a work of fiction here. Birkeland's life had plenty of incident but perhaps not that much documentation, and Jago builds from the letters, papers and contemporary reports that exist, and fills in gaps with reasonable extrapolations. I would personally prefer footnotes or endnotes to make clear what the sources are, though the bibliography helps here. The book is at its best in the early chapters dealing with the perils of Arctic field observations, and at its worst while failing to help us understand Birkeland's descent into paranoia and substance abuse towards the end of his life. But it's never less than an interesting read.
Given my incentive for reading it, I would have liked to see a great deal more science, but that's just me. I did enjoy some of the glimpses into the way that scientific endeavour worked at the turn of the twentieth century, including examples of international collaboration and friendship, and also obstruction. There's also an epilogue that explains a little about the importance of Birkeland's discoveries and how long it took for his theories to be proved correct (not until about fifty years after his death).
Finally, the subtitle of this book is "How one man sacrificed love, happiness and sanity to unlock the secrets of space." This would better read "How one man found happiness by unlocking the secrets of space while seriously neglecting his physical and mental health and all his friends and relatives." But that's what obsession is for, right?
