Rebel Star - Colin Stuart ****

It would only be fair to expect that we knew everything there is to know about our friendly neighbourhood star, the Sun. After all, without it we certainly wouldn't be here, it's extremely close in astronomical turns and it has been studied for millennia. Yet, as Colin Stuart reveals, there's plenty we still don't know - and of the bits we do apparently know, I was amazed how much was new to me.

I suspect that solar missions and research just don't get the same level of media coverage as, say, missions to Mars with the potential for long-term manned exploration. We are, after all, never going to send people to the Sun. But there are some great stories about attempts to find out more about what is, inevitably, an inhospitable environment. So, for example, Stuart tells the fascinating tale of the Solor and Heliospheric Observatory (SOHO) mission. Launched at the end of 1995, a human error turned the satellite into a $1 billion piece of space junk... or so it seemed. The efforts to get it back going and the final outcome make great reading.

The first part of the book fills in the history of our understanding of the Sun and how it works, while more of the rest covers areas where research is still current and our understanding still remains partial. A lot of this part concentrates on what's going on in the Sun's outer layers and the solar wind and coronal mass ejections that are propelled out from it, sometimes in our direction, which has can have a potentially dire impact on a world dependent on electronics and satellites.

I learned a lot here, and Stuart's enthusiasm is clear. If I have a negative it's that this enthusiasm perhaps carries him away sometimes to give us rather more detail on some of the more abstruse aspects of the complex electromagnetic phenomena that shape sunspots, produce solar flares and more. Similarly, although the likes of Alfven waves and magnetohydrodynamics are essential in getting an understanding what's going on we get, perhaps, a little too much detail for a book aimed at a general audience.

However, if things do get a little over-detailed sometimes, we're soon back to finding out about new and interesting discoveries. Stuart starts most chapters with a scene-setting narrative and throughout the book is packed with information and delights.

Mathematics with Love – Mary Stopes-Roe *****

Admittedly it’s early days (this review is written in January), but this, for me, is the surprise hit of the year so far! I approached this book with trepidation, but found it absolutely delightful. It is described on the cover as the “courtship correspondence of Barnes Wallis, inventor of the bouncing bomb”, and contains a series of letters between Wallis and his cousin and eventual wife Molly Bloxham, along with some useful annotation by their daughter, Mary. The courtship itself is not without difficulties, as Wallis was 18 years older than the 17-year-old Molly at the start of the correspondence, and her father, not surprisingly, wasn’t too pleased about the interest of such an elderly suitor, but that isn’t the only reason the letters are interesting – it’s also because of maths, and Wallis’s position in the UK as the engineering hero of the Second World War. (Incidentally, it seemed very strange to see letters addressed to “Barnes” – I had always assumed Barnes Wallis was a ...

Data Empire - Roopika Risam ****

The central thesis presented by Roopika Risam is that information gives us (and particularly countries) the power to organise, control and dominate others. Although I have a couple of issues with the presentation, this is a genuinely interesting trip through the history of our use of stored information from the earliest tallies to the latest information technology. I loved a quote from Lisa Gitelman that data is is always 'cooked' so 'raw data is an oxymoron'. This neatly underlines Risam's thesis that data and information are not neutral facts, but rather tools that (like everything from fire to electronics) can be used for good or evil. As we are taken through the historical context, it can sometimes be a little difficult to judge whether Risam regards a particular example as bad or good, even when the outcome is disastrous. One thing I didn't like too much is the adherence to a popular science writing approach that has got distinctly hackneyed: opening chapte...

Andrew Jaffe - Five way interview

Andrew Jaffe is professor of astrophysics and cosmology at Imperial College, London and director of the Imperial Centre for Inference and Cosmology. His new book is The Random Universe. Why science? I’ve always been interested in science, in particular in  astronomy, astrophysics, and space. One of my earliest memories - back in nursery school in New Jersey, I think - was watching one of the moon launches. I wanted that excitement to be part of my life! I never got to be an astronaut, but I did get to be part of the Planck Satellite team, and was privileged to be able to travel to the ESA Spaceport in French Guiana to watch the launch.  In between, I was lucky enough to have a supportive family, get a good education, and find inspiring teachers, mentors, and collaborators. They helped me model the universe, and helped me learn how to refine those models in the face of experimental and observational evidence. That is, they taught me to be a scientist. Why this book? The Random...
