Anaximander and the Nature of Science - Carlo Rovelli ****

In my experience, working scientists often get history of science wrong - in this case, as it's arguably more history of philosophy, I can't say whether or not Carlo Rovelli is straying far from what's known to make his point, but what he has to say about the Greek philosopher Anaximander from the 6th century BC is fascinating.

All I really knew about Anaximander was that he had proposed an early cosmology, with a cylindrically shaped Earth and the light of the Sun and stars produced by fire contained in rings that had holes in to let the light out. This was interesting, but not necessarily hugely inspiring. By contrast, what Rovelli proposes is that Anaximander came up with a number of steps forward that were effectively foundational for the scientific method.

At first this seemed like hyperbole from someone championing a particular favourite, but by the end of the book I was convinced. What Rovelli attributes to Anaximander are the idea of a non-flat Earth floating in space - surrounded by the heavens, rather than a flat Earth with the heavens above; building on Thales' example as the first known explanation for physical processes without divine intervention; introducing the concept of natural law; and challenging his master's ideas rather than simply building on them.

The next step Rovelli takes is to try to understand why 6th century BC Greece was pretty well the only such starting point. He emphasises, for instance, that despite their impressive mathematics, astronomical observation and technological developments, Chinese philosophers and scientists never came up with the insight of a non-flat Earth floating in space, only switching to this viewpoint when they received information from missionaries in the seventeenth century. He suggests that it was the combination of having the first fully phonetic simple alphabet, the lack of dominant royalty and the independence of the city states that enabled this revolution in thinking in Miletus where Anaximander was based.

The rest of the book (about half of it) concentrates on what science is, the dangers of cultural relativism and understanding the world without gods. I found this a lot less interesting, partly because I'd seen most of it before, and partly because it is more a matter of paddling in the murky waters of philosophy of science rather than the more interesting (to me) origins of the history of science. 

For the first half alone, though, this is a book well worth having. Rovelli has improved hugely since his early super-waffly titles - if you have an interest in where science came from, this is arguably his best so far.

Govert Schilling - Five Way Interview

Govert Schilling is an acclaimed and prize-winning freelance astronomy writer and broadcaster in the Netherlands. His articles appear in Dutch newspapers and magazines, but he also has written for New Scientist, Science and BBC Sky at Night Magazine, and he is a contributing editor of Sky & Telescope. He wrote dozens of books (including a couple of children’s books) on a wide variety of astronomical topics, many of which have been translated into English, German, Italian, and Chinese, among other languages. In 2007, the International Astronomical Union (IAU) named asteroid 10986 Govert after him, and in 2014, he received the David N. Schramm Award for high-energy astrophysics science journalism from the High Energy Astrophysics Division of the American Astronomical Society.His latest book is Target Earth . Why science? We live in troubling times. Fake news and conspiracy theories abound, and trust in science is diminishing. Many adults don't seem to realize that almost everythi...

The Infinite Book – John D. Barrow ****

Authors are often asked to review books on a topic they’ve written on themselves. The reasoning is sensible – they ought to know something about the subject – but there’s always that uneasy suspicion that there’s going to be a bit of bias creeping in. So I think it’s only fair to admit up front that I have written a book on infinity (of which more later). Infinity is a wonderful subject, because it’s intimately mind-bending (if the combination sounds paradoxical, that’s what infinity is all about) and gives you the chance to pull in all sorts of different concepts and assocations along the way, something Barrow does with great gusto. There’s a surprisingly large amount of coverage here for God, and for the universe, and the book jumps around from Aristotle to Hilbert’s Infinite Hotel (explained at great length), from the paradoxes of infinite sets to the paradoxes of time travel. Overall it’s an enjoyable journey that gives plenty of opportunity to be amazed and surprised. The...

Battle of the Big Bang - Niayesh Afshordi and Phil Harper *****

It's popular science Jim, but not as we know it. There have been plenty of popular science books about the big bang and the origins of the universe (including my own Before the Big Bang ) but this is unique. In part this is because it's bang up to date (so to speak), but more so because rather than present the theories in an approachable fashion, the book dives into the (sometimes extremely heated) disputed debates between theoreticians. It's still popular science as there's no maths, but it gives a real insight into the alternative viewpoints and depth of feeling. We begin with a rapid dash through the history of cosmological ideas, passing rapidly through the steady state/big bang debate (though not covering Hoyle's modified steady state that dealt with the 'early universe' issues), then slow down as we get into the various possibilities that would emerge once inflation arrived on the scene (including, of course, the theories that do away with inflation). ...
