Sharon Ann Holgate - five way interview

Former Young Professional Physicist of the Year, Sharon Ann Holgate has a doctorate in experimental physics and has worked for the past twenty-five years as a freelance science writer and broadcaster. She has presented on BBC Radio 4 and the BBC World Service, and written for newspapers and magazines including Science, New Scientist and The Times Higher Education Supplement. She was co-author of The Way Science Works, a children’s popular science book shortlisted for the 2003 Junior Prize in the Aventis Prizes for Science Books, and has written four undergraduate physics textbooks. She also contributed to the popular science books 30-Second Quantum Theory and 30-Second Energy. In 2022 Sharon Ann won the Institute of Physics’ William Thomson, Lord Kelvin Medal and Prize 'for work in communicating science to a wide variety of audiences and for positive representations of scientists from non-traditional backgrounds'. Her latest book is Nuclear Fusion: The Race to Build a Mini-Sun on Earth. 

Why science?

I didn’t realise it at the time, but it was actually watching an episode of Fingerbobs as a 4-year-old child that inspired my interest in science. Crow wanted a drink but couldn’t reach the water in the bottom of a large beaker, so he began dropping in pebbles until the water level rose enough for him to sip it. I can remember dragging my Mum into the garden to collect some stones and then to the kitchen to find a jug so that we could repeat what I had just seen. I was absolutely transfixed by the water rising! 

Why this book? 

The climate emergency is one of the biggest challenges the world has ever faced. So the seeking of new, clean forms of electricity generation that would reduce our reliance on fossil fuels is an important and exciting topic to write about.  The history of fusion research is also fascinating: I particularly enjoyed learning about the 1950s machines such as the quirkily named Perhapsatron and the sci-fi sounding Hydromagnetic Plasma Gun. Discovering more about the ITER project in southern France and the work taking place at the National Ignition Facility in the United States was equally engrossing, as was interviewing scientists and engineers from the private companies currently building and testing a range of different fusion technologies.   

What date would you put on nuclear fusion power stations going live, and why then?

A few years after a commercially viable fusion technology has been perfected. Recent fusion history has shown that there is no point in trying to estimate a specific date. As with any developing area of science, fusion research is a process of discovery so you can’t necessarily achieve a definite aim within a set time frame. 

What’s next? 

Promoting my forthcoming book Communicating Science Clearly: A Self-Help Guide for Students and Researchers. Then, as a follow-on from winning the Lord Kelvin Medal, I am hoping to be able to use my experiences as a person with a physical disability to help encourage students from diverse backgrounds to enter science. 

What’s exciting you at the moment? 

Some of the recent advances in materials science and technology have certainly caught my eye. For instance the next generation of solar cells contain a layer of perovskite which makes them more efficient at converting sunlight into electricity. Also, who would have thought people would be walking around in trainers made from fungi!

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...

E=mc2: A biography of the world’s most famous equation – David Bodanis *****

David Bodanis is a storyteller, and he fulfils this role with flair in E=mc2. The premise of the book is simple – Einstein himself has been biographed (biographised?) to death, but no one has picked out this most famous of equations, dusted it down and told us what it means, where it comes from and what it has delivered. Allegedly, Bodanis was inspired to write the book after hearing see an interview with actress Cameron Diaz in which she commented that she’d really like to know what that famous collection of letters was all about. Although the book had been around for a while already when this review was written (September 2005), it seemed a very apt moment to cover it, as the equation is, as I write, exactly 100 years old. So when better to have a biography? Bodanis starts off by telling us about the individual elements of the equation. What the different letters mean, where the equal sign comes from and so on. This is entertaining, though he seems to tire of the approach on...
