Eureka! The Birth of Science – Andrew Gregory *****

“Oh, no, not the ancient Greeks? Yawn, yawn, what a bore.” If this is your natural reaction to a book on the ancient Greek origins of science, hold on there. It’s easy enough to think of the Greeks as a bit of a bore because they tended to be long winded and philosophising (and they foisted geometry on us, for goodness sake) – but the fact is that their work, mostly wrong though it may be, is the foundation of all of science.

What’s more, Andrew Gregory makes the whole business interesting, without resorting to any fancy literary tricks – it’s a straightforward historical tour of the Greek prehistory of science that is simply bursting with insight. If you’ve ever wondered why it was such a big deal that Galileo and others should suggest that the Earth wasn’t at the centre of things, here is part of the explanation. It’s not just a matter of selfish assumption, but the entire Aristotelian physics depended on it. Without the Earth at the centre of things, his equivalent of gravity simply wouldn’t work.

Because so much of the actual detail is wrong, it’s also easy to dismiss the ancient Greeks’ input to science – but, as Gregory emphasizes, it was a huge leap to move from the assumption that the cause of natural events and objects was mythological and down to the intervention of gods, to a rule-based cosmos where it was possible to deduce a logical explanation for events. He contrasts, for instance, the Babylonians and Egyptians, who achieved great technological feats, and were quite capable of recording and predicting natural events, but who resolutely put the explanation of why down to supernatural intervention, and who consistently resorted to inconsistent myth to explain how the cause was working.

Some would argue that Gregory has been a little premature – that the ancient Greeks weren’t so much the earliest part of the history of science, but the prehistory of science. To make this distinction, what the Greeks did is often called natural philosophy, based on observation and argument, as opposed to science, based on observation, experiment and the development and refinement of theory from those observations and experiments. So it’s worth taking a look at least three other books that ascribe the birth of science to later midwifes:

Medieval friar Roger Bacon in my Roger Bacon: The First Scientist
Leonardo da Vinci in Michael White’s Leonardo, and
Galileo in John Gribbin’s Science: A History

but even they would agree with Gregory how significant the ancient Greeks foundations are, and the great thing is to get a very effective grounding in these Greek ideas in a single, compact and enjoyable book. Nice one.

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). ...

Why Nobody Understands Quantum Physics - Frank Verstraete and Céline Broeckaert **

It's with a heavy heart that I have to say that I could not get on with this book. The structure is all over the place, while the content veers from childish remarks to unexplained jargon. Frank Versraete is a highly regarded physicist and knows what he’s talking about - but unfortunately, physics professors are not always the best people to explain physics to a general audience and, possibly contributed to by this being a translation, I thought this book simply doesn’t work. A small issue is that there are few historical inaccuracies, but that’s often the case when scientists write history of science, and that’s not the main part of the book so I would have overlooked it. As an example, we are told that Newton's apple story originated with Voltaire. Yet Newton himself mentioned the apple story to William Stukeley in 1726. He may have made it up - but he certainly originated it, not Voltaire. We are also told that ‘Galileo discovered the counterintuitive law behind a swinging o...

Ctrl+Alt+Chaos - Joe Tidy ****

Anyone like me with a background in programming is likely to be fascinated (if horrified) by books that present stories of hacking and other destructive work mostly by young males, some of whom have remarkable abilities with code, but use it for unpleasant purposes. I remember reading Clifford Stoll's 1990 book The Cuckoo's Egg about the first ever network worm (the 1988 ARPANet worm, which accidentally did more damage than was intended) - the book is so engraved in my mind I could still remember who the author was decades later. This is very much in the same vein, but brings the story into the true internet age. Joe Tidy gives us real insights into the often-teen hacking gangs, many with members from the US and UK, who have caused online chaos and real harm. These attacks seem to have mostly started as pranks, but have moved into financial extortion and attempts to destroy others' lives through doxing, swatting (sending false messages to the police resulting in a SWAT te...
