Eureka: How Invention Happens - Gavin Weightman ***




Updated for paperback version
There's an interesting point made by Gavin Weightman in Eureka - the way that many inventions were the brainchild of an amateur, a tinkerer, who managed to get the invention going pretty badly, before it was then picked up elsewhere, typically by a larger organization which carried it forward to become a commercial or practical product. It's certainly true of the five examples he focusses on in the book.

These are powered flight, television, the barcode, the PC and the mobile phone (cellphone). In each case, Weightman gives us a long section in which he introduces that individual (or small team) of amateurs, plunges back into their historical antecedents - because invention doesn't come from nowhere, there is plenty of groundwork that precedes it - and then takes us through the detailed work of the amateurs and the way that the invention was then taken up and commercialised.

For me, the two best sections were the ones on TV and the barcode, in part because I'd read more detailed books on the other topics. The TV section is interesting because it gives the best balance between Baird and Farnsworth I've seen. In my youth (in the UK) John Logie Baird was the only name you ever heard when it came to inventing the television, while more recently the magnificently named Philo T. Farnsworth has taken centre stage (because unlike Baird, his TV concept was not a dead-end mechanical approach), but Weightman puts both in their rightful positions. 

The barcode section was particularly interesting because it's something I've never read about, and it's easy to overlook the barcode as an invention, even though it plays a major role every time we go shopping, not to mention its importance in inventory and stock control. It was fascinating to learn that it was inspired by Morse code. My only real criticism of this chapter is the way that it concentrates solely on the hardware, where the development of the software was equally crucial in the story.

These are, without doubt, interesting stories, but the reason I haven't given the book a higher star rating is that it's not a great read. The historical sections get rather dull and over-detailed (this is particularly the case in the flight section, not helped by jumping around wildly chronologically in a way that really doesn't help the reader). I also think that the central thesis that inventions come from isolated amateurs, which the author presents as if it's a new observation, would have been better if he had read more around the study of creativity and innovation. It's an observation dating back for decades that in the creative field ideas come from individuals, while development tends to come from teams, which is why in part there was a strong historical tendency for the more individual-oriented UK of the early to mid 20th Century to come up with inventions, while the US, where businesses tended to have a stronger team approach, was better at developing those inventions to finished products.

The other problem with the thesis is selectivity. It's certainly true that these inventions were the work of amateurs, but it's not true of, say, the laser and a whole host of modern inventions where the technology level is often too high for amateurs to get anywhere in a garage lab. An interesting set of stories, then, but could have been told better and the central thesis could do with some expansion and extra sophistication.

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…

Conjuring the Universe - Peter Atkins *****

It's rare that I'd use the term 'tour de force' when describing a popular science book, but it sprang to mind when I read Conjuring the Universe. It's not that the book's without flaws, but it does something truly original in a delightful way. What's more, the very British Peter Atkins hasn't fallen into the trap that particularly seems to influence US scientists when writing science books for the public of assuming that more is better. Instead of being an unwieldy brick of a book, this is a compact 168 pages that delivers splendidly on the question of where the natural laws came from.

The most obvious comparison is Richard Feynman's (equally compact) The Character of Physical Law - but despite being a great fan of Feynman's, this is the better book. Atkins begins by envisaging a universe emerging from absolutely nothing. While admitting he can't explain how that happened, his newly created universe still bears many resemblances to  nothing a…

Big Bang (Ladybird Expert) - Marcus Chown ****

As a starting point in assessing this book it's essential to know the cultural background of Ladybird books in the UK. These were a series of cheap, highly illustrated, very thin hardbacks for children, ranging from storybooks to educational non-fiction. They had become very old-fashioned, until new owners Penguin brought back the format with a series of ironic humorous books for adults, inspired by the idea created by the artist Miriam Elia. Now, the 'Ladybird Expert' series are taking on serious non-fiction topics for an adult audience.

Marcus Chown does a remarkable job at packing in information on the big bang, given only around 25 sides of small format paper to work with. He gives us the concepts, plenty about the cosmic microwave background, plus the likes of dark energy, dark matter, inflation and the multiverse. To be honest, the illustrations were largely pointless, apart from maintaining the format, and it might have been better to have had more text - but I felt …
