The Character of Physical Law - Richard Feynman ***

This was a late discovery for me amongst Richard Feynman's books, and it's something of an oddity. Like all the books with his name on, this wasn't a case of Feynman sitting down to write a book; he never wrote a single book - in this case it's a transcription of a set of lectures Feynman gave at Cornell University which were broadcast in the UK by the BBC.
What the great physicist sets out to do is to explore the nature of physical laws. Where this works best (and he would probably have hated this suggestion) is where he was at his most philosophical. In the first lecture he explored just what was meant by physical laws and this is genuinely interesting stuff, especially as it's something we rarely give much thought to.
After that he goes on to cover specific areas, with lectures on gravity, maths, conservation, symmetry, the arrow of time and probability, before pulling things together in a final lecture on the search for new laws. For me these chapters don't work quite as well in book form, partly because we miss the visual aspects of Feynman's talks, and partly because they are perhaps a little too summary for the topics covered. The other slight problem with specifics is that inevitably some of the content (from the 1960s) is quite dated - particularly in the 'new laws' section, where he covers particle physics at a point before quarks and when the particle zoo seemed out of control. It's interesting from a historical perspective of what the understanding was like at the time, but it's not an ideal way to find out about particle physics.
Overall, an essential if you want to have a complete picture of Feynman's output, and fascinating in that opening chapter, but not the best of the Feynman books.

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…
