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.

A Tale of Seven Scientists - Eric Scerri ***

Scientists sometimes tell us we're in a post-philosophy world. For example, Stephen Hawking and Leonard Mlodinow in The Grand Design bluntly say that that philosophy is 'dead' - no longer required, as science can do its job far better. However, other scientists recognise the benefits of philosophy, particularly when it is applied to their own discipline. One such is Eric Scerri, probably the world's greatest expert on the periodic table, who in this challenging book sets out to modify the philosophical models of scientific progress.

I ought to say straight away that A Tale of Seven Scientists sits somewhere on the cusp between popular science and a heavy duty academic title. For reasons that will become clear, I could only give it three stars if rating it as popular science, but it deserves more if we don't worry too much about it being widely accessible.

One minor problem with accessibility is that I've never read a book that took so long to get started. First t…

Four Way Interview - Tom Cabot

Tom Cabot is a London-based book editor and designer with a background in experimental psychology, natural science and graphic design. He founded the London-based packaging company, Ketchup, and has produced and illustrated many books for the British Film Institute, Penguin and the Royal Institute of British Architects. Tom has held a lifelong passion to explain science graphically and inclusively ... ever since being blown away by Ray and Charles Eames’ Powers of Ten at an early age. His first book is Eureka, an infographic guide to science.

Why infographics?
For me infographics provided a way to present heavy-lifting science in an alluring and playful, but ultimately illuminating, way. And I love visualising data and making it as attractive as the ideas are.  The novelty of the presentation hopefully gets the reader to look afresh. I love the idea of luring in readers who might normally be put off by drier, more monotone science – people who left science behind at 16. I wanted the boo…

Einstein's Greatest Mistake - David Bodanis ****

Books on Einstein and his work are not exactly thin on the ground. There's even been more than one book before with a title centring on Einstein's mistake or mistakes. So to make a new title worthwhile it has do something different - and David Bodanis certainly achieves this with Einstein's Greatest Mistake. If I'm honest, the book isn't the greatest on the science or the history - but what it does superbly is tell a story. The question we have to answer is why that justifies considering this to be a good book.
I would compare Einstein's Greatest Mistake with the movie Lincoln -  it is, in effect, a biopic in book form with all the glory and flaws that can bring. Compared with a good biography, a biopic will distort the truth and emphasise parts of the story that aren't significant because they make for a good screen scene. But I would much rather someone watched the movie than never found out anything about Lincoln - and similarly I'd much rather someon…
