Merlin's Tour of the Universe - Neil deGrasse Tyson ***

This book is something of a reboot. It was Neil deGrasse Tyson's first title, dating back to 1997, but was reissued 'fully revised and updated for the 21st century' in 2024. It's mostly a cut and paste book from the Q&A section in a magazine, despite which (or perhaps because of which) it's one of Tyson's better books.

The idea is that the questions are answered by Merlin who is 'a visitor from the Andromeda galaxy who is as old as Earth and who has observed all major scientific events of Earth history.' Although some of the questions are from children (and the illustrations look like they were drawn by one) it's intended to appeal to all ages. The book is split into 13 sections, mostly with astronomical topics (such as Earth, Moon, Planets, Black Holes and Quasars), though with a couple of more physics-based sections including Gravity and Light and Telescopes.

The questions themselves vary from entertaining thought experiments such as 'What would happen if the Earth suddenly stopped rotating?' to straightforward astronomical queries like 'Why is Mars red?' Bearing in mind this was originally a short column, most answers are less than a page long and don't provide any depth. They are lightweight and easily digested. Unfortunately, they are sometimes either incomplete or even wrong. In the examples I give above (selected randomly) - very few of the implications of the Earth stopping are covered, and while the 'why is Mars red' question reasonably puts it down to iron, Tyson then spoils things by saying 'it's the same reason mammal blood is red' - unfortunately it's not. It's down to the structure of ring of an atoms in haemoglobin called porphyrin.

In other writing, Tyson's biggest faults tend to be a weak grasp of history of science and some impressive jingoism (I'm thinking particularly of his Space Chronicles where he says, of instance 'In the fifties, sixties, seventies, part of the eighties, every plane that landed in your city was made in America' - pure fiction.) Here, there is relatively little opportunity for either failing (though it does seem unlikely that Newton was at Woolsthorpe in 1710), which is why things seem to work reasonably well.

It's rather tedious to read this book end to end, but at risk of awarding faint praise, it would work well as a toilet companion, taking in a brief article or two at a time.

Luna: Moon Rising (SF) - Ian McDonald ****

I'm not the natural audience for this book. Game of Thrones l eaves me cold - and it's hard not to feel the influence of GoT (and a whole lot of Dune ) underneath a veneer of science fiction and the trappings of a South American drug cartel in the cod-medieval family power battles and chivalric details. There are even dragons (of a sort). I'd be really sad if the future did involve this sort of throwback feudalism. However, remarkably, despite this I found Luna: Moon Rising kept me engaged. The fact is that Ian McDonald can put together a good plot with intricate machinations, which is enough to carry the reader through what can be a bewildering collection of characters. The two page scene-setter saying who did what to whom at the start was useful, but I could have done with family trees for the main family as I was constantly forgetting who was who - especially easy as McDonald endows many families with characters with the same first initial (e.g. Ariel and Al...

Adventures of a Computational Explorer - Stephen Wolfram ***

Stephen Wolfram, the man behind the scientist's mathematical tool of choice, Mathematica, plus a whole host of other software products, including the uncanny Wolfram Alpha knowledge engine, is undoubtedly a genius of the first order. In this book, we get an uncensored excursion into the mind of genius - which is, without doubt, a fascinating prospect. The book consists of a collection of essays and speeches that Wolfram has produced over the last ten to fifteen years, covering an eclectic range of topics. Like all such collections, the result is something that lacks the coherence of a book with a narrative that runs through it, inevitably introducing a degree of repetition and a mix of interesting and not-so-interesting topics - but there's likely to be something to catch the attention anyone who is into computing or mathematics. One of the most interesting pieces is the opening one, where Wolfram describes being a consultant on the SF movie Arrival. He seems to hav...

The AI Paradox - Virginia Dignum ****

This is a really important book in the way that Virginia Dignum highlights various ways we can misunderstand AI and its abilities using a series of paradoxes. However, I need to say up front that I'm giving it four stars for the ideas: unfortunately the writing is not great. It reads more like a government report than anything vaguely readable - it really should have co-authored with a professional writer to make it accessible. Even so, I'm recommending it: like some government reports it's significant enough to make it necessary to wade through the bureaucrat speak. Why paradoxes? Dignum identifies two ways we can think about paradoxes (oddly I wrote about paradoxes recently , but with three definitions): a logical paradox such as 'this statement is false', or a paradoxical truth such as 'less is more' - the second of which seems a better to fit to the use here. We are then presented with eight paradoxes, each of which gives some insights into aspects of t...
