Mistress of Science - John Croucher and Rosalind Croucher ***

It's quite common these days to read clickbait headlines telling us about the 'Most brilliant woman scientist/mathematician you never heard of' - I doubt if I'm alone in saying quite genuinely I had never heard of Janet Taylor, or her work that John and Rosalind Croucher believe made her deserving of that title 'Mistress of Science.' In the preface to the book we are told that 'Janet Taylor, born Jane Ann Ionn, made her mark as a brilliantly gifted scientist of her era,' - but is this hyperbole or reality?

This is far more a conventional biography than a scientific one, so while Taylor's work is certainly mentioned, we don't get a lot of detail about the science or the maths (a bit odd, given one of the Crouchers is a professor of statistics). As a biography, it's readable, if in a fairly old-fashioned style that spends rather more word count than is necessary on the comings and goings of the royals - though to be fair, the Crouchers give us a vivid picture of some aspects of life in London at the time, such as the thriving docks or the replacement of Old London Bridge. That rather dated style comes across, for example, in describing the visits made by Queen Charlotte to Taylor's Bedfordshire school (sponsored by the Queen) we are told that 'The queen's beautiful blue-grey eyes and genuine warmth always put the girls quickly at ease,' a sentence that seems more fitting for a romantic novel than a biography.

There are some biographical aspects of interest - for example around Taylor's meeting her future husband when he helped her pick up her (English) books after she dropped them in the street in Antwerp (they were eventually married in the Hague) and in the odd tangle of their names. Pre-marriage they were Jane Ann Ionn and George Taylor Jane - so potentially she could have ended up as the amusing Jane Jane - but perhaps to spare this, Taylor dropped his surname for his maternal middle name and 'Jane Ann' became Janet.

So, what were Taylor's scientific achievements? She seems to have been the driving force behind setting up a 'navigational academy' with her husband and writing on navigation - not exactly science, but a practical application of mathematics that was well-established, but that Taylor was able to fine tune in some respects. She was gifted and enjoyed mathematics. She was clearly fascinated from an early age by nautical astronomical navigation and seemed to have spent much of her spare time in early adulthood reading about this and performing her own calculations. A driving force in her work seemed to be to make correction for the non-spherical nature of the Earth - though the planet had been known to be an oblate spheroid since Newton's day, it seems the corrections employed weren't accurate enough for Taylor's level of precision.

From the Crouchers' book it seems very likely that Janet Taylor certainly could have been a significant scientist in an age where this was a practical profession for a woman. It's rather harder to pin down any original scientific or mathematical contribution she was able to make. We are often told about her 'calculations' and 'equations' but not given any detail on what she did mathematically, or how original that mathematics was. She devised a fascinating mechanical navigational calculator - a kind of nineteenth century Antikythera mechanism - which seems to have had a lot of potential, but never went into production. (Once again, the Crouchers don't give us enough technical detail be sure what it could have done, though the Admiralty assessment of the time suggests it would have been impractical to use.)

I think it's best to think of Taylor as the navigational equivalent of an engineer. She didn't come up with original maths or science, but was highly successful in her application of existing knowledge. This is not to undermine her achievements - especially given the bias against female participation of the time - but is a far more accurate description than to call her a 'brilliantly gifted scientist.' (Part of the problem is the rather loose use of the term 'science' before the mid-nineteenth century.) Despite the repeated use of the 's' word, this is not in any sense a scientific biography, but interesting nonetheless: it remains well worth reading as a life story.

Target Earth – Govert Schilling *****

I was biased in favour of this great little book even before I started to read it, simply because it’s so short. I’m sure that a lot of people who buy popular science books just want an overview and taster of a subject that’s brand new to them – and that’s likely to work best if the author keeps it short and to the point. Of course, you may want to dig deeper in areas that really interest you, but that’s what Google is for. That basic principle aside, I’m still in awe at how much substance Govert Schilling has managed to cram into this tiny book. It’s essentially about all the things (natural things, I mean, not UFOs or space junk) that can end up on Earth after coming down from outer space. That ranges from the microscopically small particles of cosmic dust that accumulate in our gutters, all the way up to the ten kilometre wide asteroid that wiped out the dinosaurs. Between these extremes are two topics that we’ve reviewed entire books about recently: meteorites ( The Meteorite Hunt...

The Decline and Fall of the Human Empire - Henry Gee ****

In his last book, Henry Gee impressed with his A (Very) Short History of Life on Earth - this time he zooms in on one very specific aspect of life on Earth - humans - and gives us not just a history, but a prediction of the future - our extinction. The book starts with an entertaining prologue, to an extent bemoaning our obsession with dinosaurs, a story that leads, inexorably towards extinction. This is a fate, Gee points out, that will occur for every species, including our own. We then cover three potential stages of the rise and fall of humanity (the book's title is purposely modelled on Gibbon) - Rise, Fall and Escape. Gee's speciality is palaeontology and in the first section he takes us back to explore as much as we can know from the extremely patchy fossil record of the origins of the human family, the genus Homo and the eventual dominance of Homo sapiens , pushing out any remaining members of other closely related species. As we move onto the Fall section, Gee gives ...

Govert Schilling - Five Way Interview

Govert Schilling is an acclaimed and prize-winning freelance astronomy writer and broadcaster in the Netherlands. His articles appear in Dutch newspapers and magazines, but he also has written for New Scientist, Science and BBC Sky at Night Magazine, and he is a contributing editor of Sky & Telescope. He wrote dozens of books (including a couple of children’s books) on a wide variety of astronomical topics, many of which have been translated into English, German, Italian, and Chinese, among other languages. In 2007, the International Astronomical Union (IAU) named asteroid 10986 Govert after him, and in 2014, he received the David N. Schramm Award for high-energy astrophysics science journalism from the High Energy Astrophysics Division of the American Astronomical Society.His latest book is Target Earth . Why science? We live in troubling times. Fake news and conspiracy theories abound, and trust in science is diminishing. Many adults don't seem to realize that almost everythi...
