Nuclear Fusion - Sharon Ann Holgate ****

Nuclear fusion should, in principle, be the perfect addition to renewables as we move away from greenhouse gas generating energy sources. Yet, more than 60 years after it was first suggested, we still don't have a single working nuclear fusion power station. (If, as the subtitle suggests, this has been a race, it has been a walking backwards three-legged race.) Sharon Ann Holgate provides a compact introduction to what nuclear fusion is, the various steps along the road that have been made so far, and why it has taken so long.

Starting with fusion as the power source of the stars, we discover the difficulty of keeping the tricky, twisty ultra hot material in the fusion reactor under control when using magnetic confinement, look at the two main technical approaches (and variants), the sheer scale of the engineering challenge, what is underway with ITER and more, along with the potential for the future.

Although this is an area beset with disappointments, one where we always seems to be decades away from practicality, Holgate balances the slightly depressing realities with the genuinely interesting science and technology involved and the still-real promise of the approach for the future, including the latest novel approaches.

Fusion is sometimes mistakenly attached to the 1954 statement from US AEC chairman that ‘It is not too much to expect that our children will enjoy in their homes electrical energy too cheap to meter,’ which seems to have been about nuclear power in general. It's certainly an ironic prediction given the rise in electricity prices - and it's likely that nuclear fusion will never be cheap, but it should provide a useful way to iron out the variation in renewable sources, and as such is still an important technology for the future. Read this book and you will have a good picture of how that is going to come about.

Phenomena - Camille Juzeau and the Shelf Studio ****

I am always a bit suspicious of books that are highly illustrated or claim to cover 'almost everything' - and in one sense this is clearly hyperbole. But I enjoyed Phenomena far more than I thought I would. The idea is to cover 125 topics with infographics. On the internet these tend to be long pages with lots of numbers and supposedly interesting factoids. Thankfully, here the term is used in a more eclectic fashion. Each topic gets a large (circa A4) page (a few get two) with a couple of paragraphs of text and a chunky graphic. Sometimes these do consist of many small parts - for example 'the limits of the human body' features nine graphs - three on sporting achievements, three on biometrics (e.g. height by date of birth) and three rather random items (GNP per person, agricultural yields of various crops and consumption of coal). Others have a single illustration, such as a map of the sewers of Paris. (Because, why wouldn't you want to see that?) Just those two s...

The Bright Side - Sumit Paul-Choudhury ***

When I first saw The Bright Side (the subtitle doesn't help), I was worried it was a self-help manual, a format that rarely contains good science. In reality, Sumit Paul-Choudhury does not give us a checklist for becoming an optimist or anything similar - and there is a fair amount of science content. But to be honest, I didn't get on very well with this book. What Paul-Choudhury sets out to do is to both identify what optimism is and to assess its place in a world where we are beset with big problems such as climate change (which he goes into in some detail) that some activists position as an existential threat. This is all done in a friendly, approachable fashion. In that sense it's a classic pop-psychology title. For me, Paul-Choudhury certainly has it right about the lack of logic of extreme doom-mongers, such as Extinction Rebellion and teenage climate protestors, and his assessment of the nature of optimism seems very reasonable, if presented at a fairly overview leve...

Rakhat-Bi Abdyssagin (born in 1999) is a distinguished composer, concert pianist, music theorist and researcher. Three of his piano CDs have been released in Germany. He started his undergraduate degree at the age of 13 in Kazakhstan, and having completed three musical doctorates in prominent Italian music institutions at the age of 20, he has mastered advanced composition techniques. In 2024 he completed a PhD in music at the University of St Andrews / Royal Conservatoire of Scotland (researching timbre-texture co-ordinate in avant- garde music), and was awarded The Silver Medal of The Worshipful Company of Musicians, London. He has held visiting affiliations at the Universities of Oxford, Cambridge and UCL, and has been lecturing and giving talks internationally since the age of 13. His latest book is Quantum Mechanics and Avant Garde Music . What links quantum physics and avant-garde music? The entire book is devoted to this question. To put it briefly, there are many different link...
