Caleb Scharf – Four Way Interview

Caleb Scharf is Director of Astrobiology at Columbia University in New York. He is the winner of the 2011 Chambliss Astronomical Writing Award from the American Astronomical Society, and the Guardian has cited his Life, Unbounded blog at Scientific American as one of the “hottest science blogs,”. His extensive research career has covered cosmology, high-energy astrophysics, and exoplanetary science, and he currently leads efforts to understand the nature of exoplanets and the environments suitable for life in the universe. He has also served as consultant for New Scientist, Discovery Channel, the Science Channel, National Geographic, The New York Times, The Wall Street Journal and others. His book Gravity’s Engines explores the influence of black holes on the universe.
Why science? 
So many evolving reasons. Curiosity, obsessiveness, and a love of stories. The more science I work on the more I see it through the lens of storytelling, and it’s hard to do better than the story of our universe. I can appreciate simplicity and elegance, but as I get older I appreciate more and more the multi-textured, layered, chaotic, and unbelievably interwoven nature of reality. It really is just amazing.
I like the perspective gained from science. It appeals to my core sense of humour that we’re these microscopic specks of cosmic filth assembled into thinking objects, and we’re gawping at the immensity of it all, and actually managing to make a small amount of sense out of it. That’s incredible, and for me is a fundamental part of our humanity.
Why this book? 
Black holes are one of the craziest and most unexpected stories in science. I wanted to cut through the haze of misty eyed rumination about their exotic physics and explain just how real and important they actually are. Every week we’re hearing about new black hole discoveries – and these tell us that super-sized versions inhabit most galaxies and have been co-joined with the nature of galaxies and stars for the past 13 billion years. Because matter falling into holes can generate colossal amounts of energy – easily more than nuclear fusion, it can profoundly influence the cosmic environment. Instead of being off-limits and hidden away, these gateways to quantum gravity help make the universe what it is today.
What’s next?
I’m working on a book called The Copernicus Complex, that comes out in 2014. I’m really excited about this. It’s all about the quest for our cosmic significance, or perhaps insignificance! Like most of my writing it drills down deep into the science, but is also about telling a great tale. I also think that there are a number of original and intriguing ideas in the book, stemming from the latest research in microbiology, exoplanets, cosmology, and even statistical inference. Hopefully it will get people talking!
What’s exciting you at the moment?
I’m always going to say the abundance of exoplanets and the search for life in the universe, but I’m also agog at what’s happening with lab-bench science right now. Incredible things are taking place in optics, quantum physics, and microbiology. I feel that we may be on the verge of a genuine shift in our understanding of the fundamentals of the microscopic world, and I can’t help but wonder how that will lead to new ways to probe the cosmos.

The Meteorite Hunters - Joshua Howgego *****

This is an extremely engaging read on a subject that everyone is aware of, but few of us know much detail about. Usually, if I'm honest, geology tends to be one of the least entertaining scientific subjects but here (I suppose, given that geo- refers to the Earth it ought to be astrology... but that might be a touch misleading). Here, though, there is plenty of opportunity to capture our interest. The first part of the book takes us both to see meteorites and to hear stories of meteorite hunters, whose exploits vary from erudite science trips to something more like an Indiana Jones outing. Joshua Howgego takes us back to the earliest observations and discoveries of meteorites and the initial doubt that they could have extraterrestrial sources, through to explorations of deserts and the Antarctic - both locations where it tends to be easier to find them. I, certainly, had no idea about the use of camera networks to track incoming meteors, which not only try to estimate where they wi...

Phenomena - Camille Juzeau and the Shelf Studio ****

I am always a bit suspicious of books that are highly illustrated or claim to cover 'almost everything' - and in one sense this is clearly hyperbole. But I enjoyed Phenomena far more than I thought I would. The idea is to cover 125 topics with infographics. On the internet these tend to be long pages with lots of numbers and supposedly interesting factoids. Thankfully, here the term is used in a more eclectic fashion. Each topic gets a large (circa A4) page (a few get two) with a couple of paragraphs of text and a chunky graphic. Sometimes these do consist of many small parts - for example 'the limits of the human body' features nine graphs - three on sporting achievements, three on biometrics (e.g. height by date of birth) and three rather random items (GNP per person, agricultural yields of various crops and consumption of coal). Others have a single illustration, such as a map of the sewers of Paris. (Because, why wouldn't you want to see that?) Just those two s...

Against the Odds - John Gribbin and Mary Gribbin ****

The number of women working in STEM subjects has expanded dramatically, but as John and Mary Gribbin make clear, in the history of science this is a very recent occurrence. Here, they bring us the stories of 12 women, from Eunice Newton Foote, born in 1819, to Vera Rubin, born in 1928 - effectively covering nearly 200 years in that Rubin died as recently as 2016. There are some names that will already be familiar from popular science histories (and deservedly so). You will find, for instance, Dorothy Hodgkin and Rosalind Franklin represented. But there are plenty like Foote that few will have come across, including Inge Lehmann, Chien-Sung Wu and Lucy Slater. While arguably Foote is there primarily to demonstrate the difficulties she faced (her discovery of an aspect of greenhouse gas behaviour was independently bettered within weeks), the rest have all made significant discoveries or developments against the odds and often missed out the recognition the deserved. The most prominent ob...
