Network Geeks – Brian E. Carpenter ***

There is a series of TV adverts in the UK that have managed to embed their tagline into common usage. The ads are for a type of varnish, and that tagline is ‘It does what it says on the tin.’ There is a real problem when a book doesn’t do what it says on the tin – you get cognitive dissonance, expecting one thing and discovering another. That’s what happened when I opened up Network Geeks.
The subtitle promises ‘how they built the internet.’ Now this is a topic I’m fascinated by. I really enjoyed the book Where Wizards Stay Up Late, which details the story of the origins of the internet, but that’s quite old now, and I assumed this would give a modern day take from the viewpoint of an internet dominated society. What you get inside is totally different, and that’s a shock.
In trendy music terms, this book is a mashup. It really has three separate themes, only linked by the author, Brian Carpenter. One is an autobiography – so we get a fair amount of Carpenter’s family history, going back a good few generations. It’s not badly written, but probably of limited interest to anyone outside Carpenter’s family. Secondly – and this is the best bit – we have a considerable account of Carpenter’s work at CERN. He worked there twice and if you are into the developed of distributed computing (as I am) there is some really interesting material here, as CERN was both groundbreaking and yet isolated from the mainstream. Apart from anything else in this technical memoir part of the book I had distinct tugs of nostalgia as I had a great time working on DEC equipment, which regularly rears its head, while in the OR department of British Airways.
So far, so good – but we are yet to encounter anything that really has to do with the supposed topic of the book. This comes into the third part of the mashup, featured in the introductory section (which is part of the reason it is such a shock when the book suddenly goes into autobiographical mode) and towards the end. But this isn’t really about ‘how the built the Internet’ at all. It is about ‘how their committees made endless bureaucratic decisions about the architecture and protocols of the internet and how the architecture and protocols developed.’ To be honest, that is a rather less exciting, and certainly a lot more specialist field.
The problem is, unless you are really into the nitty gritty of how the committees that control the internet work, this probably isn’t for you. Carpenter falls into a few writing traps in naming far too many people we aren’t really interested in, using endless acronyms we don’t really care about and giving much too much detail on the minutiae to the extent that we lose the big picture. Here’s a not atypical snippet to get a feel: ‘Internet standards, originally endorsed by DARPA, came from the IETF by 1991, and certainly not from the ITU or the ISO, the twin homes of CLNP. On the other hand, CLNP was officially defined and had already been picked up for the next version of DECnet, a significant factor in the minicomputer market then served by the Internet.’
It’s not that this is a bad book – it just doesn’t do what it says on the tin, and I can only recommend it for the rather narrow audience for whom this kind of thing is meat and drink.

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…
