Physics and Technology for Future Presidents – Richard A. Muller ***

This is, in a way, the supercharged version of one of my favourite popular science books, Physics for Future Presidents. That book is superb. It’s pitched at just the right level and explains all the physics-based science any administrator could need, in language that is approachable and enjoyable. It’s a delight.
This is a more heavyweight take on the subject. Quite literally – it weighs getting on for two kilos, and I felt I’d been doing weight training when I finished reading it. Once again, Richard A. Muller gives us an approach that is supposed to give potential presidential candidates and other administrators the details they need to get a good grasp of the physical sciences and technology, but somehow, for me it just didn’t work as well this time.
Don’t get me wrong – there’s lots of good stuff in it. Muller really gives a complete introductory physics course here, going into a lot more depth about the fundamental science rather than just the applications, which he concentrates on in the earlier book. It has most of the content of the other title (some omissions – I was sad that pebble bed reactors only get a passing reference now), but much, much more theory. That isn’t as frightening as it sounds – it’s theory presented in a very accessible and friendly fashion.
So why don’t I like it as much? In the first place, there’s just too much in it. It really is more like the book of a course than a popular science book, down to each chapter ending in discussion topics, research topics, essay questions, multiple choice questions… far too much of a textbook. Strangely, I also disliked it when the author got a bit too personal, bringing in more about himself. This usually works well in popular science, but seemed out of place in something so like an academic course.
There was also one point of the physics that worried me. To keep things simple, I guess, Muller makes a big thing of light being a wave, and despite covering quantum theory does this as much as possible from a wave viewpoint. Photons have to get a mention but are brushed aside with great frequency and he plays them down as wave packets rather than particles. I can only quote Richard Feynman: ‘I want to emphasize that light comes in this form – particles. It is very important to know that light behaves like particles, especially for those of you who have gone to school, where you were probably told something about light behaving like waves. I’m telling you the way it does behave – like particles.’ Much though I like Richard Muller’s writing, I can hardly disagree with Feynman.
All in all then, it’s a great textbook for a physics course for non-scientists, and there’s plenty of stuff in there to interest scientists as well. But for an enjoyable popular science read, please turn to Physics for Future Presidents.

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…
