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.

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 ...

Pagans (SF) - James Alistair Henry *****

There's a fascinating sub-genre of science fiction known as alternate history. The idea is that at some point in the past, history diverged from reality, resulting in a different present. Perhaps the most acclaimed of these books is Kingsley Amis's The Alteration , set in a modern England where there had not been a reformation - but James Alistair Henry arguably does even better by giving us a present where Britain is a third world country, still divided between Celts in the west and Saxons in the East. Neither the Normans nor Christianity have any significant impact. In itself this is a clever idea, but what makes it absolutely excellent is mixing in a police procedural murder mystery, where the investigation is being undertaken by a Celtic DI, Drustan, who has to work in London alongside Aedith, a Saxon reeve of equivalent rank, who also happens to be daughter of the Earl of Mercia. While you could argue about a few historical aspects, it's effectively done and has a plot...

Amazing Worlds of Science Fiction and Science Fact: Keith Cooper ****

There's something appealing (for a reader like me) about a book that brings together science fiction and science fact. I had assumed that the 'Amazing Worlds' part of the title suggested a general overview of the interaction between the two, but Keith Cooper is being literal. This is an examination of exoplanets (planets that orbit a different star to the Sun) as pictured in science fiction and in our best current science, bearing in mind this is a field that is still in the early phases of development. It becomes obvious early on that Cooper, who is a science journalist in his day job, knows his stuff on the fiction side as well as the current science. Of course he brings in the well-known TV and movie tropes (we get a huge amount on Star Trek ), not to mention the likes of Dune, but his coverage of written science fiction goes into much wider picture. He also has consulted some well-known contemporary SF writers such as Alastair Reynolds and Paul McAuley, not just scient...
