Why Information Grows - César Hidalgo ***

Something that is absolutely essential to understand this book, subtitled 'The evolution of order from atoms to economies', on the fascinating topic of the nature of information in the world, and its relationship with the economy, is that the author is an academic at M.I.T.’s Media Lab.

When I first got involved in IT in the 1970s, we were in awe of the Media Lab and all the ultra-clever, way-out technology concepts that they rolled out, convincing us that we were seeing the future in the visionary work. But over time, none of their concepts really seemed to become a reality. They might have inspired others, but they continued to be ultra-clever, way-out oddities that rarely managed to cross the divide to the real world.

I felt the same about this book. It started out, like a visit to the Media Lab, as a dazzling mix of information theory and economics and philosophy - but in the end it all appeared to be on the surface. It never really got anywhere. And along the way it was often repetitive to the point that I strongly felt that I was being talked down to.

I suppose it's a big point to make, but the author repeats the importance and presence of information so many times in the first few chapters. He also makes statements that just aren't true. He says, for instance, in one of those tedious personal story examples American authors seem programmed to start chapters with that his daughter's birth was 'facilitated not by objects, but by the information embedded in those objects'. What he really meant was 'by objects and the information embedded in them' because the information alone wouldn’t have achieved the goal. There’s a fuzziness here in the expression of the thesis, combined with not particularly effective examples in explaining, for instance, the relationship of information theory and the second law of thermodynamics that gives the book a feeling of something that is imagined to be a lot more effective than it really is.

It’s not a bad book in intent. It is really important to think about the nature of imagination, and the idea that the manufactured objects we use are ‘crystallised imagination’ would be excellent if we were only told it once, rather than what felt like 50 times. It’s also interesting to consider how imagination has shaped our modern world and how it has an impact on national economies. But the Media Lab treatment, rather than illuminating, dazzles us to the extent that it’s hard to see what lies beneath.

Things get a little better, if duller, when Hidalgo focuses primarily on economics - though here the clear flaw is in the description of economics as a science (can anything so inconsistent be a science?), which comes through strongly. What is well worth doing is the examination of why different parts of the world have very different economies, though I don’t think Hidalgo gives enough consideration to aspects like natural resources, stable and (relatively) uncorrupt government and health.

Definitely a book that’s worth a look, but with strong provisos.

Cosmology for the Curious - Delia Perlov and Alex Vilenkin ***

In the recently published The Little Book of Black Holes we saw what I thought was pretty much impossible - a good, next level, general audience science title, spanning the gap between a typical popular science book and an introductory textbook, but very much in the style of popular science. Cosmology for the Curious does something similar, but coming from the other direction. This is an introductory textbook, intended for first year physics students, with familiar textbook features like questions to answer at the end of each chapter. Yet by incorporating some history and context, plus taking a more relaxed style in the writing, it's certainly more approachable than a typical textbook.

The first main section, The Big Bang and the Observable Universe not only covers basic big bang cosmology but fills in the basics of special and general relativity, Hubble's law, dark matter, dark energy and more. We then move onto the more speculative (this is cosmology, after all) aspects, brin…

Astrophysics for People in a Hurry – Neil deGrasse Tyson *****

When I reviewed James Binney’s Astrophysics: A Very Short Introduction earlier this year, I observed that the very word ‘astrophysics’ in a book’s title is liable to deter many readers from buying it. As a former astrophysicist myself, I’ve never really understood why it’s considered such a scary word, but that’s the way it is. So I was pleasantly surprised to learn, from Wikipedia, that this new book by Neil deGrasse Tyson ‘topped The New York Times non-fiction bestseller list for four weeks in the middle of 2017’.

Like James Binney, Tyson is a professional astrophysicist with a string of research papers to his name – but he’s also one of America’s top science popularisers, and that’s the hat he’s wearing in this book. While Binney addresses an already-physics-literate audience, Tyson sets his sights on a much wider readership. It’s actually very brave – and honest – of him to give physics such prominent billing; the book could easily have been given a more reader-friendly title such …

Once upon and Algorithm - Martin Erwig ***

I've been itching to start reading this book for some time, as the premise was so intriguing - to inform the reader about computer science and algorithms using stories as analogies to understand the process.

This is exactly what Martin Erwig does, starting (as the cover suggests) with Hansel and Gretel, and then bringing in Sherlock Holmes (and particularly The Hound of the Baskervilles), Indiana Jones, the song 'Over the Rainbow' (more on that in a moment), Groundhog Day, Back to the Future and Harry Potter.

The idea is to show how some aspect of the story - in the case of Hansel and Gretel, laying a trail of stones/breadcrumbs, then attempting to follow them home - can be seen as a kind of algorithm or computation and gradually adding in computing standards, such as searching, queues and lists, loops, recursion and more.

This really would have been a brilliant book if Erwig had got himself a co-author who knew how to write for the public, but sadly the style is mostly heavy…
