The Friar and the Cipher – Lawrence & Nancy Goldstone **

The subtitle Roger Bacon and the Unsolved Mystery of the Most Unusual Manuscript in the World should be a bit of a giveaway here. There isn’t going to be a satisfying conclusion to this book because it’s about an unsolved mystery. In fact, the text is largely concerned with two subjects – the 13th century proto-scientist Roger Bacon, and the Voynich manuscript, a strange enciphered text that has been ascribed to Bacon on flimsy evidence, though most scholars now believe it to be several hundred years too modern for Bacon. The manuscript has never been deciphered – many “translations” have been hopelessly based on anagrams that could mean anything – and it may well never be, or even be capable of meaningful translation.

So the manuscript itself – by appearance a mixture of a bizarre herbal that contains some plants that may be of New World origin with strange astrological images – isn’t exactly news. Neither, frankly, are the chapters that the Goldstones dedicate to Bacon and the man often considered one of the manuscript’s first owners, the Elizabethan Bacon fan, John Dee. There is a much better book on Bacon in Brian Clegg’s The First Scientist (not even referenced by the Goldstones) and Dee gets a far better treatment in Benjamin Wooley’s The Queen’s Conjuror (which at least is in their bibliography).

In the coverage of Bacon’s life and work there are a number of small but telling flaws that suggest rather rapid research from limited sources. Statements made as fact about Bacon’s history (his birthdate, for instance, which could as easily be 1220 as the 1214 given in the book, or the timing of his journey to Paris, which is largely speculative) have no documentary basis. Bacon’s medieval science is totally misunderstood when his term “species” is interpreted as forces – light, for example, was considered by Bacon to be an example of species, which surely even the Goldstones wouldn’t think of as a force?

Similarly there are some worrying errors when they finally get onto manuscript and its encipherment (only about the last fifth of the book). They comment “In some ways there has been no real progress at all. From Roger Bacon’s time… [onwards] any code or cipher fashioned by human ingenuity was susceptible to decipherment by the same means… no matter how brilliant the mind that fashioned a code, an equally brilliant mind might break it.” This isn’t misinterpretation, it’s plain wrong. As they should have picked up from their reading of Simon Singh’s The Code Book, for nearly 100 years now there has been a totally unbreakable form of cipher – the one time pad. It’s a pain to use, but it isn’t just difficult to break, it is absolutely (no matter how clever you are) impossible to break. Period.

The Voynich manuscript is still a fascinating subject, and the book’s quick coverage of the attempts to decipher it are interesting if frustrating, because the authors seem determined to keep it as a medieval mystery when it almost certainly isn’t. But this just isn’t the right book for the subject.

Where are the chemistry popular science books?

by Brian Clegg
There has never been more emphasis on the importance of public engagement. We need both to encourage a deeper interest in science and to counter anti-scientific views that seem to go hand-in-hand with some types of politics. Getting the public interested in science both helps recruit new scientists of the future and spreads an understanding of why an area of scientific research deserves funding. Yet it is possible that chemistry lags behind the other sciences in outreach. As a science writer, and editor of this website, I believe that chemistry is under-represented in popular science. I'd like to establish if this is the case, if so why it is happening - and what can be done to change things. 

An easy straw poll is provided by the topic tags on the site. At the time of writing, there are 22 books under 'chemistry' as opposed to 97 maths, 126 biology and 182 physics. The distribution is inevitably influenced by editorial bias - but as the editor, I can confirm …

Make, Think, Imagine - John Browne ***

When you read a politician's memoirs you know that, nine times out of ten, it won't really quite work, because the message can't carry a whole book. It's reminiscent of the old literary agent's cry of 'Is it a book, or is it an article?' It's not that there aren't a lot of words in such tomes. It's almost obligatory for these books to be quite chunky. But it's a fair amount of work getting through them, and you don't feel entirely satisfied afterwards. Unfortunately, that's rather how John Browne (former head of oil giant BP)'s book comes across.

It's not that the central thread is unimportant. It used to be the case, certainly in the UK, that science, with its roots in philosophy and the pursuit of knowledge, was considered far loftier than engineering, growing out of mechanical work and the pursuit of profit. There is, perhaps, still a whiff of this around in some circles - so Browne's message that engineering has been…

Bloom - Ruth Kassinger ***

There is much fascinating material in this chunky book by Ruth Kassinger. It may be my total ignorance of biology and everyone else knows these things, but I learnt so much - for example that seaweed is algae and not a plant, about algae's role in the development of land plants, about the algae in lichen and its contribution to coral reefs.

The book is divided into four broad sections: on the origins and development of algae, on algae (and particularly seaweed) as food, on making use of algae, for example, for biofuel, and on algae and climate change, particularly the bleaching of coral and algal blooms. This is all done in a very approachable writing style, mixing descriptive material that is never over-technical with narrative often featuring visits to different locations and to talk to a range of experts from those who study to algae to those who cook them.

There are two problems though. Firstly, the book is too long at 380 pages. Each section could do with a trim, but this wa…
