Louise Devoy - Five Way Interview

Dr Louise Devoy is Senior Curator at the Royal Observatory, Greenwich, UK. Louise has a background in astrophysics and the history of science. She has worked at various museums in the UK and is interested in astronomical instruments, women in astronomy and historic observatories. She is author of Royal Observatory Greenwich: A History in Objects, published to celebrate the Observatory’s 350th anniversary in 2025. 

Why science?

I'm curious about the world around me and science is great way to ask questions. I love digging into the history of science to see how our ideas have changed over time and to appreciate how science runs in parallel with the trends of the period, whether it's improving navigation for trade or using innovative technologies to create exciting new fields of study.

Why this book?

Various books have been written about certain aspects of the Observatory's history (longitude, timekeeping, the Astronomers Royal etc) but I wanted to do something more holistic that that showed how astronomers at Greenwich worked across many different topics including magnetism, meteorology, weights and standards, astrophysics, and even measuring the density of the Earth.  I've spent the past five years rummaging through the collection stores and archives to pick out the most interesting (and surprising!) objects, some of which have never have been highlighted before. It's a quirky mixture of technical objects (telescopes, clocks, instruments) along with less obvious objects that give us an insight into what it was like to live and work on site.

What has been the most lasting impact of the Royal Observatory Greenwich? 

It's the global reference location for time and longitude. Every time you look at a watch or a map, you're relying on the countless people who worked here to transform star data into essential information for coordinating time across navigation, travel and trade.

What’s next?

We're working on First Light, which is our ambitious project to completely transform the Observatory site by 2028 with more engaging and accessible displays and facilities. Check our website for more details. 

What’s exciting you at the moment?

We've been working with NAROO colleagues at Paris Observatory to digitise around 2,000 photographic glass plates taken here in Greenwich from 1893-1908. For scientists, these plates offer a fossilised record of how the sky looked over a century ago, giving them the chance to calculate tiny shifts in star positions over time. For historians, these plates give us an insight into the life and work of the astronomers during that period, including the 'lady computers' who were the first women to work as professional astronomers at Greenwich. It's amazing how these small square pieces of glass can give us so much information!

The Laws of Thought - Tom Griffiths *****

In giving us a history of attempts to explain our thinking abilities, Tom Griffiths demonstrates an excellent ability to pitch information just right for the informed general reader.  We begin with Aristotelian logic and the way Boole and others transformed it into a kind of arithmetic before a first introduction of computing and theories of language. Griffiths covers a surprising amount of ground - we don't just get, for instance, the obvious figures of Turing, von Neumann and Shannon, but the interaction between the computing pioneers and those concerned with trying to understand the way we think - for example in the work of Jerome Bruner, of whom I confess I'd never heard.  This would prove to be the case with a whole host of people who have made interesting contributions to the understanding of human thought processes. Sometimes their theories were contradictory - this isn't an easy field to successfully observe - but always they were interesting. But for me, at least, ...

Einstein's Fridge - Paul Sen ****

In Einstein's Fridge (interesting factoid: this is at least the third popular science book to be named after Einstein's not particularly exciting refrigerator), Paul Sen has taken on a scary challenge. As Jim Al-Khalili made clear in his excellent The World According to Physics , our physical understanding of reality rests on three pillars: relativity, quantum theory and thermodynamics. But there is no doubt that the third of these, the topic of Sen's book, is a hard sell. While it's true that these are the three pillars of physics, from the point of view of making interesting popular science, the first two might be considered pillars of gold and platinum, while the third is a pillar of salt. Relativity and quantum theory are very much of the twentieth century. They are exciting and sometimes downright weird and wonderful. Thermodynamics, by contrast, has a very Victorian feel and, well, is uninspiring. Luckily, though, thermodynamics is important enough, lying behind ...

Nanotechnology - Rahul Rao ****

There was a time when nanotechnology was both going to transform the world and wipe us out - a similar position to our view of AI today. On the positive transformation side there was K. Eric Drexler's visions in the 1986 Engines of Creation. Arguably as much science fiction as engineering possibilities, it predicted the ability to use vast armies of assemblers to put objects together from individual atoms.  On the negative side was the vision of grey goo, out of control nanotechnology consuming all in its path as it made more and more copies of itself. In 2003, for instance, the then Prince Charles made the headlines  when newspapers reported ‘The prince has raised the spectre of the “grey goo” catastrophe in which sub-microscopic machines designed to share intelligence and replicate themselves take over and devour the planet.’ These days the expectations have been eased down a notch or two. Where nanotechnology has succeeded, it has been with the likes of atom-thick mat...
