Stephen James O'Meara - Four Way Interview

Stephen James O’Meara is an award-winning astronomer and author/co-author of more than a dozen books, including the third edition of Oxford’s A Dictionary of Space Exploration (2018). He is a columnist and editor for Astronomy magazine, and former associate editor of GeminiFocus and Sky & Telescope magazines. Asteroid 3637 is named O’Meara in his honour. His latest book is Mars.

Why science?

Science is the key to understanding mysteries. I grew up during the golden age of science fiction and space exploration, when questions initially outweighed answers. 

What comes especially to mind from that era was the first episode of the 1963 TV programme, The Outer Limits, called The Galaxy Being. In it, a peaceful being from the Andromeda Galaxy is accidentally brought to Earth via radio transmission. The military tries to destroy the Being but fails. In response, the Galaxy Being simply tells the earthlings to stop using force, reminding them that there are powers in the Universe beyond anything they know. He then tells them, 'There is much you have to learn. You must explore. You must reach out. Go to your homes. Go and give thought to the mysteries of the Universe.' And that’s what I did, and have done ever since I saw that program at the age of six. The point is we fear what we don’t understand. We need science to alleviate those fears.

Why this book?

Mars has fascinated me since childhood when I began observing it with a 60-mm refractor from my back porch in the 1960s, followed by seeing the 1971 global dust storm at the age of 14 through the 9-inch Alvan Clark refractor at Harvard College Observatory — and  shown to me by the dust storm’s discoverer Dennis Milon. This global storm was the one that largely obscured the planet from the Mariner 9 spacecraft’s view when the craft achieved orbit around Mars on November 14th of that year, just two days before my 15th birthday. Admittedly, I was fascinated by the lore of the Red Planet — as presented by Lowell with his canals, and as depicted in science fiction (especially from the pages of Edgar Rice Burroughs). To me, Mars was a planet alive with mysteries. Little has changed in that respect. Did Mars have water in the past? Does Mars have water today? Did life (microbial) once exist on the Red Planet? Does life still exist on the Red Planet today?  What happened to Mars’s atmosphere? Is Mars habitable? Are humans capable of colonising Mars? No other planet has captured human imagination the way Mars has, and I believe this book is simply a tribute to the ongoing investigation of a planet that was once seen as a mirror of the Earth — and to the imagination of a child who dared to wonder about that world and who continues to do so today.

What’s next?

I’ve always been fascinated with the visible phenomena of the daytime and twilight skies — it’s a part of the visible Universe that largely goes unnoticed. Yet each day offers us the possibility of seeing visual phenomena that capture the ever-changing mood of Earth’s ocean of air and the way light plays with it, or the way the human eye perceives it: the green flash, prismatic ice crystal displays, volcanic twilights, atmospheric glories and so much more. All these phenomena bring us closer to understanding the planet on which we live.  

What’s exciting you at the moment?

You mean aside from from life, nature, and the visible universe? I suppose I’m really looking forward to the upcoming missions to Mars, which should continue to unravel the mysteries surrounding what could potentially be humanity’s next home.

God: the Science, the Evidence - Michel-Yves Bolloré and Olivier Bonnassies ***

This is, to say the least, an oddity, but a fascinating one. A translation of a French bestseller, it aims to put forward an examination of the scientific evidence for the existence of a deity… and various other things, as this is a very oddly structured book (more on that in a moment). In The God Delusion , Richard Dawkins suggested that we should treat the existence of God as a scientific claim, which is exactly what the authors do reasonably well in the main part of the book. They argue that three pieces of scientific evidence in particular are supportive of the existence of a (generic) creator of the universe. These are that the universe had a beginning, the fine tuning of natural constants and the unlikeliness of life.  To support their evidence, Bolloré and Bonnassies give a reasonable introduction to thermodynamics and cosmology. They suggest that the expected heat death of the universe implies a beginning (for good thermodynamic reasons), and rightly give the impression tha...

Humble Pi - Matt Parker ****

Matt Parker had me thoroughly enjoying this collection of situations where maths and numbers go wrong in everyday life. I think the book's title is a little weak - 'Humble Pi' doesn't really convey what it's about, but that subtitle 'a comedy of maths errors' is far more informative. With his delightful conversational style, honed in his stand-up maths shows, it feels as if Parker is a friend down the pub, relating the story of some technical disaster driven by maths and computing, or regaling us with a numerical cock-up. These range from the spectacular - wobbling and collapsing bridges, for example - to the small but beautifully formed, such as Excel's rounding errors. Sometimes it's Parker's little asides that are particularly attractive. I loved his rant on why phone numbers aren't numbers at all (would it be meaningful for someone to ask you what half your phone number is?). We discover the trials and tribulations of getting cal...

Quantum 2.0 - Paul Davies ****

Unlike the general theory of relativity or cosmology, quantum physics is an aspect of physics that has had a huge impact on everyday lives, particularly through the deployment of electronics, but also, for example, where superconductivity has led to practical applications. But when Paul Davies is talking about version 2.0, he is specifically describing quantum information, where quantum particles and systems are used in information technology. This obviously includes quantum computers, but Davies also brings in, for example, the potential for quantum AI technology. Quantum computers have been discussed for decades - algorithms had already been written for them as early as the 1990s - but it's only now that they are starting to become usable devices, not at the personal level but in servers. In his usual approachable style, Davies gives us four chapters bringing us up to speed on quantum basics, but then brings in quantum computing. After this we don't get solid quantum informat...
