Nikola Tesla and the Electric Future - Iwan Rhys Morus ****

Nikola Tesla divides the world into three. Those who haven't a clue who he was, those who think he was a genius scientist, thwarted by the industrial/military complex, and those who think he was a brilliant electrical engineer who became a fantasist as he got older.

Presumably because it makes the best story, existing biographies of Tesla tend to support the second viewpoint: they lap up every fantastical suggestion Tesla made and give examples of what were nothing more than science fiction as an example of his 'ahead of his time' genius. So, for example, they claim he invented the mobile phone, because he said his (totally unworkable) project for transmitting energy through the Earth would mean you could have a device in your pocket that enabled communication anywhere in the world. This is a bit like saying Cyrano de Bergerac invented the Apollo space vehicles because he said you could get into space using rockets.

Compared with earlier biographers, Iran Rhys Morus strikes a good balance, recognising Tesla's exception ability in electrical engineering, yet making it clear just how unlikely many of his later claims were. As a historian of science, Morus gives us lots of material on the work that was going on at the same time, putting what Tesla did into context, whether it's coverage of other inventors of the period such as Edison, or on the development of the new electrically-based world that Tesla played a part in.

For this reason, I have given the book four stars - it is, without doubt, the best of the bunch at assessing Tesla's technological achievements and putting them into context. However, there is also a significant problem here. This isn't a biography at all, it's a history book. Morus gives us so much context that you can go several pages at a time without Telsa being mentioned at all. We really find out nothing about Tesla, the man. There's no mention, for example, of his strange behaviours and habits, from hosting pigeons in his hotel room to his food obsessions. There is nothing about his relations with other people or his infamous 'death ray in a box' that turned out to be a Wheatstone bridge. Whole swathes of his inventions are missed, from the vibrating platform to the disc-based pump. And there's little about how Tesla seems to have misunderstood much of the physics of the day.

To be honest, at times this lack of focus on Tesla makes the book a little dull. Don't get me wrong - I have given Nikola Tesla and the Electric Future four stars because it is, without doubt, an excellent history of the part of the electrical revolution that Tesla was involved in. But it isn't the biography I hoped for that combined accurate history, good understanding of the science and a thorough exploration of Tesla himself. We're still waiting for that.

Lucy Jane Santos - Four Way Interview

Lucy Jane Santos is an expert in the history of 20th century leisure, health and beauty, with a particular interest in (some might say obsession with) the cultural history of radioactivity. Writes & talks (a lot) about cocktails and radium. Her debut book Half Lives: The Unlikely History of Radium was published by Icon Books in July 2020.

Why science?

I have always been fascinated by the idea of science especially our daily interactions with and understandings of science – especially in a beauty context. I could spend hours pondering the labels of things on my bathroom shelf. What is 4-t-butylcyclohexanol (as a random example)? Do I really understand what I am putting on my face and spending my money on? Would it change my purchase habits if I did?  

Why this book?

This book came from an accidental discovery – that there was a product called Tho Radia which contained radium and thorium. I found out about it because I actually bought a pot of it – along with a big batch of other produc…

Rewilding: Paul Jepson and Cain Blythe ****

Those who are enthusiastic about saving the environment often have a mixed relationship with science. They might for example, support organic farming or oppose nuclear power, despite organics having no nutritional benefit and requiring far more land to be used to raise the same amount of crops, while nuclear is a green energy source that should be seen as an essential support to renewables. This same confusion can extend to the concept of rewilding, which is one reason that the subtitle of this book uses the word 'radical'.

As Paul Jepson and Cain Blythe make clear, though, radical change is what is required if we are to encourage ecological recovery. To begin with, we need to provide environments for nature that take in the big picture - thinking not just of individual nature reserves but, for example, of corridors that link areas allowing safe species migration. And we also need to move away from an arbitrary approach to restricting to 'native' species, as sometimes…

Is Einstein Still Right? - Clifford Will and Nicolas Yunes ***

If there's one thing that gets a touch tedious in science reporting it's the news headlines that some new observation or experiment 'proves Einstein right' - as if we're still not sure about relativity. At first glance that's what this book does too, but in reality Clifford Will and Nicolas Yunes are celebrating the effectiveness of the general theory of relativity, while being conscious that there may still be situations where, for whatever reason, the general theory is not sufficient.

It's a genuinely interesting book - what Will and Yunes do is take experiments that are probably familiar to the regular popular science reader already and expand on the simplified view of them we are usually given. So, for example, one of the first things they mention is the tower experiments to show the effect of gravitational red shift. I was aware of these experiments, but what we get here goes beyond the basics of the conceptual experiment to deal with the realities of d…
