Beam – Jeff Hecht ***

Beam‘s subtitle is ‘the race to make the laser’ and this was a story that was crying out for a good popular scientific history. Not only is there really interesting physics behind the laser, there was a genuine tense race, strong personalities, bizarre problems with security clearances and more to make for a gripping story.
I’ve come rather late to Beam (first published in 2005) because, frankly, the book doesn’t seem to have been very visible – and I’m afraid I can understand why. Although there are all the elements of a great story there, Jeff Hecht is probably not the right person to tell it. On the physics side, while there is a lot of detail of the precise excitation processes required for masers and lasers, there isn’t really enough background on quantum physics to give it context.
As for the story itself, the book suffers from kitchen-sink-itis. Hecht seems to feel it necessary to mention ever single tiny contribution to the research, whether or not it had a direct impact on the key players. And though the story really does get interesting when, for instance, we get onto Gordon Gould’s you’d-laugh-if-you-didn’t-cry security problems that meant he wasn’t able to read his own work, much of the storytelling gets horribly bogged down and repetitive, making it hard to follow the narrative.
The final problem is limiting the book to the race to create the first laser – it would have had a wider interest if Hecht had brought in the development of the solid state lasers we all have littering our homes in CD players and the like.
All in all, there is plenty of good stuff here, and I’m not aware of anyone else who has told the story in such detail, but you have to work quite hard to get to the nuggets.

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…

Jim Baggott - Four Way Interview

Jim Baggott is a freelance science writer. He trained as a scientist, completing a doctorate in physical chemistry at Oxford in the early 80s, before embarking on post-doctoral research studies at Oxford and at Stanford University in California. He gave up a tenured lectureship at the University of Reading after five years in order to gain experience in the commercial world. He worked for Shell International Petroleum for 11 years before leaving to establish his own business consultancy and training practice. He writes about science, science history and philosophy in what spare time he can find. His books include Atomic: The First War of Physics and the Secret History of the Atom Bomb (2009), Higgs: The Invention and Discovery of the ‘God Particle’ (2012), Mass: The Quest to Understand Matter from Greek Atoms to Quantum Fields (2017), and, most recently, Quantum Space: Loop Quantum Gravity and the Search for the Structure of Space, Time, and the Universe (2018).

Quantum Space: Jim Baggott *****

There's no doubt that Jim Baggott is one of the best popular science writers currently active. He specialises in taking really difficult topics and giving a more in-depth look at them than most of his peers. The majority of the time he achieves with a fluid writing style that remains easily readable, though inevitably there are some aspects that are difficult for the readers to get their heads around - and this is certainly true of his latest title Quantum Space, which takes on loop quantum gravity.

As Baggott points out, you could easily think that string theory was the only game in town when it comes to the ultimate challenge in physics, finding a way to unify the currently incompatible general theory of relativity and quantum theory. Between them, these two behemoths of twentieth century physics underlie the vast bulk of physics very well - but they simply can't be put together. String theory (and its big brother M-theory, which as Baggott points out, is not actually a the…
