Einstein and the Quantum – A. Douglas Stone *****

This is without doubt a five star, standout book, though there are a couple of provisos that mean it won’t work for everyone.
If you ask someone who has read a bit of popular science about the founders of quantum theory they will mention names like Planck, Bohr, Schrödinger and Heisenberg – but as Douglas Stone points out, the most significant name in laying the foundations of quantum physics was its arch-critic, Albert Einstein. You may be aware that Einstein took Planck’s original speculation about quantised energy and turned it into a description of the action of real particles in his 1905 paper photoelectric effect that won him his Nobel Prize – but what is shocking to learn is just how much further Einstein went, producing a whole string of papers that made the development of quantum theory almost inevitable. It was Einstein, for instance, who came up the earliest form of wave/particle duality.
I have never read anything that gave detail on this fascinating period of the development of physics the way that Stone does. This isn’t really a scientific biography. Stone does dip into Einstein’s life, but often in a fairly shallow way. What is much more significant is the way he shows us the building blocks that would make the full quantum theory being put in place. It really is absolutely fascinating. Science writers like me tend to skip over large chunks of the way this developed, throwing in just the highlights, but Stone really gives us chapter and verse, without ever resorting to mathematics, demonstrating the route to quantum theory in a way, he suggests, that most working physicists have no ability to appreciate. Remarkable.
I have two provisos. A minor one is that Stone’s context is not as well-researched as his physics. We are told that Arrhenius moved to Europe from Sweden, perhaps a slight surprise for most Swedes to realise that they don’t live in Europe. And he calls Rutherford British – admittedly the great New Zealand physicist did most of his best work in the UK, but I’m not sure we can count him as our own.
The bigger warning is that this book isn’t going to work for everyone. While I found some of the explanations – notably of a Bose Einstein condensate – the clearest I’ve ever read, Stone does fall into the typical trap of the physicist-as-science-writer of assuming what comes naturally to him is equally accessible to the general reader. I don’t think he makes clear enough the basis in thermodynamics of the early work, perhaps assuming that the statistical mechanics of vibrating bodies, and other essentials that constantly turn up in the early workings, are sufficiently straightforward as classical physics that they don’t need much explanation. Without that clear foundation, his later explanations may be slightly hard going – but I can only say that if you really want a feel for where quantum physics came from to persevere and go with the flow, because it is well worth it.
P.S. I wish someone had told the cover designer how inappropriate the solar system-like atom picture on the cover is for the topic!

  1. From Wikipedia: "Ernest Rutherford, 1st Baron Rutherford of Nelson, OM FRS[1] (30 August 1871 – 19 October 1937) was a New Zealand-born British physicist who became known as the father of nuclear physics"

    1. Hint: Wikipedia isn't always right. To call Rutherford British is imperialist at best.

The Antigravity Enigma - Andrew May ****

Antigravity - the ability to overcome the pull of gravity - has been a fantasy for thousands of years and subject to more scientific (if impractical) fictional representation since H. G. Wells came up with cavorite in The First Men in the Moon . But is it plausible scientifically?  Andrew May does a good job of pulling together three ways of looking at our love affair with antigravity (and the related concept of cancelling inertia) - in science fiction, in physics and in pseudoscience and crankery. As May points out, science fiction is an important starting point as the concept was deployed there well before we had a good enough understanding of gravity to make any sensible scientific stabs at the idea (even though, for instance, Michael Faraday did unsuccessfully experiment with a possible interaction between gravity and electromagnetism). We then get onto the science itself, noting the potential impact on any ideas of antigravity that come from the move from a Newtonian view of a...

The World as We Know It - Peter Dear ***

History professor Peter Dear gives us a detailed and reasoned coverage of the development of science as a concept from its origins as natural philosophy, covering the years from the eighteenth to the twentieth century. inclusive If that sounds a little dry, frankly, it is. But if you don't mind a very academic approach, it is certainly interesting. Obviously a major theme running through is the move from largely gentleman natural philosophers (with both implications of that word 'gentleman') to professional academic scientists. What started with clubs for relatively well off men with an interest, when universities did not stray far beyond what was included in mathematics (astronomy, for instance), would become a very different beast. The main scientific subjects that Dear covers are physics and biology - we get, for instance, a lot on the gradual move away from a purely mechanical views of physics - the reason Newton's 'action at a distance' gravity caused such ...

It's On You - Nick Chater and George Loewenstein *****

Going on the cover you might think this was a political polemic - and admittedly there's an element of that - but the reason it's so good is quite different. It shows how behavioural economics and social psychology have led us astray by putting the focus way too much on individuals. A particular target is the concept of nudges which (as described in Brainjacking ) have been hugely over-rated. But overall the key problem ties to another psychological concept: framing. Huge kudos to both Nick Chater and George Loewenstein - a behavioural scientist and an economics and psychology professor - for having the guts to take on the flaws in their own earlier work and that of colleagues, because they make clear just how limited and potentially dangerous is the belief that individuals changing their behaviour can solve large-scale problems. The main thesis of the book is that there are two ways to approach the major problems we face - an 'i-frame' where we focus on the individual ...
