The Quiet Revolution of Caroline Herschel - Emily Winterburn ****

Thankfully, with the attention now given to the history of women in the sciences, the subtitle of Emily Winterburn's book 'the lost heroine of astronomy' is not really accurate. Admittedly, thanks to the relative coverage given to less substantial contributors to science such as Ada Lovelace, some might underestimate Caroline Herschel's contribution. However, I've read several books on Herschel's work now, notably Claire Brock's The Comet Sweeper and Michael Hoskin's book on both William and Caroline, Discoverers of the Universe.

What Winterburn brings impressively is a feel for Caroline the person - although Winterburn is a historian of science, this is more a biography of the active part of a scientist's life rather than a scientific biography. Having read the story often from William Herschel's viewpoint, there's a feeling of watching one of those clever movies where you see the same situation from two individual's very different viewpoints. Here it is the incredibly productive Caroline's view of the world. As Winterburn makes clear, Caroline was not the first woman to be involved in science, nor even the first to get recognition as such by the scientific authorities - but she was the first to become visible in this way in the UK and her contribution, both in 'comet sweeping' and totally restructuring the catalogue of nebulae (as well as increasing its content significantly) was highly significant.

There's always a danger with a biography, especially of a 'forgotten figure' in history, that the account becomes worthy and dull. This isn't at all the case here. Winterburn has apparently been able to access a large quantity of primary material, and this is largely a very readable account. It's topped and tailed by relatively brief summaries of Caroline's life before and after her astronomical work, but the vast majority focuses on around 10 years when she was actively using telescopes, finding comets and nebulae and amassing an impressive catalogue.

Caroline comes across as someone who is far more interested in family and work than a social life. For a poor background, she was thrust with her brother into a middle class world on the fringes of Royal patronage and clearly wasn't always comfortable with the social requirements this brought. However, Winterburn portrays well Caroline's very slow acceptance of her own worth and gives plenty of context from the gradual improvement in women's independence to the influence the French Revolution was having on English life. What is very clear is that Caroline was far more than her brother's helper - though there is no doubt that he would not have achieved as much as he did without her.

My only issue with the book is that it does seem under-edited. All books contain the odd error, but there seemed slightly more than usual. For example, we are told that Venus, the brightest thing in the night sky after the Moon, has a lower apparent magnitude than the brighter stars and there's a reference to the University of Aberdeen, which didn't exist in the eighteenth century. The bigger aspect of the editing issue as a reader, though, was repetition. In the second half of the book particularly, some points are made repeatedly from chapter to chapter, sometimes with similar wording. In the worst instance, the repetition is in the same few lines:

 ‘He then set about promoting this eclipse as a public astronomical spectacle, using maps to show where to stand for the best view… to encourage people to go out and view this… he had maps printed showing exactly where to go to view it. ‘

This did make me pull back from what otherwise would have been a five star rating, but it's still a very useful and approachable insight into Caroline's work and its social and political context.

Beyond Weird - Philip Ball *****

It would be easy to think 'Surely we don't need another book on quantum physics.' There are loads of them. Anyone should be happy with The Quantum Age on applications and the basics, Cracking Quantum Physics for an illustrated introduction or In Search of Schrödinger's Cat for classic history of science coverage. Don't be fooled, though - because in Beyond Weird, Philip Ball has done something rare in my experience until Quantum Sense and Nonsense came along. It makes an attempt not to describe quantum physics, but to explain why it is the way it is.

Historically this has rarely happened. It's true that physicists have come up with various interpretations of quantum physics, but these are designed as technical mechanisms to bridge the gap between theory and the world as we see it, rather than explanations that would make sense to the ordinary reader.

Ball does not ignore the interpretations, though he clearly isn't happy with any of them. He seems to come clo…

Mercury - William Sheehan ****

Driving to work one morning several years ago, I spotted a tiny white dot close to the rising sun. ‘That’s Venus,’ I said to myself. Almost immediately I saw another, much brighter dot a few degrees away. ‘No, that’s Venus – the first one must be, um ... Mercury.’ Even with a lifelong interest in astronomy, I always manage to forget Mercury.

With eight planets in the Solar System, one of them has to be the least interesting – and Mercury got the short straw. That’s a relative statement, though, and a diligent author could still dig up enough fascinating facts about that tiny dot by the Sun to fill a short book. William Sheehan has done a brilliant job of doing just that.

One of the reasons Mercury is so easy to forget is that it’s almost impossible to get a good view of it from Earth. Even after the invention of the telescope, which turned planets like Mars and Jupiter into explorable worlds, Mercury remained a mystery – and the subject of some pretty wild speculations. In 1686, for exa…

Everything You Know About Planet Earth is Wrong - Matt Brown ****

This is the latest of a series of 'Everything You Know About... is Wrong' books from Matt Brown. Although I always feel slightly hard done by as a result of the assertion in the title, as there are certainly things here I know that aren't wrong (I mean, come on, the first corrected piece of 'knowledge' is that 'The Earth is only 6,000 years old' and I can't imagine many readers will 'know' that), it's a handy format to provide what are often surprisingly little snippets of information that are very handy for 'did you know' conversations down the pub (or showing up your parents if you're a younger reader).

Some of the incorrect statements that head each article are well-covered, if often still believed (for example, people thought that world was flat before Columbus), some are a little tricksy in the wording (such as seas have to wash up against land) and some are just pleasantly surprising (countering the idea that gold is a rar…
