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 Great Silence – Milan Cirkovic ****

The great 20th century physicist Enrico Fermi didn’t say a lot about extraterrestrial life, but his one utterance on the subject has gone down in legend. He said ‘Where is everybody?’ Given the enormous size and age of the universe, and the basic Copernican principle that there’s nothing special about planet Earth, space should be teeming with aliens. Yet we see no evidence of them. That, in a nutshell, is Fermi’s paradox.

Not everyone agrees that Fermi’s paradox is a paradox. To some people, it’s far from obvious that ‘space should be teeming with aliens’, while UFO believers would scoff at the suggestion that ‘we see no evidence of them’. Even people who accept that both statements are true – including  a lot of professional scientists – don’t always lose sleep over Fermi’s paradox. That’s something that makes Milan Cirkovic see red, because he takes it very seriously indeed. In his own words, ‘it is the most complex multidisciplinary problem in contemporary science’.

He points out th…

The Happy Brain - Dean Burnett ****

This book was sitting on my desk for some time, and every time I saw it, I read the title as 'The Happy Brian'. The pleasure this gave me was one aspect of the science of happiness that Dean Burnett does not cover in this engaging book.

Burnett's writing style is breezy and sometimes (particularly in footnotes) verging on the whimsical. His approach works best in the parts of the narrative where he is interviewing everyone from Charlotte Church to a stand-up comedian and various professors on aspects of happiness. We get to see the relevance of home and familiarity, other people, love (and sex), humour and more, always tying the observations back to the brain.

In a way, Burnett sets himself up to fail, pointing out fairly early on that everything is far too complex in the brain to really pin down the causes of something as diffuse as happiness. He starts off with the idea of cheekily trying to get time on an MRI scanner to study what his own brain does when he's happy, b…

Bodyology - Mosaic Science ****

It's a good sign when you pick up a book intending to read one chapter and end up reading three. It's very moreish. This is because it's made up of short, self-contained articles, originally published on a website. Often an edited collection of articles by different authors suggests a boring read, but here the articles are good pieces of journalism with plenty to interest the reader.

The topics are all vaguely human body related, but thankfully not all medical (not my favourite subject) - so, for example, as well as stories of a person cured of Lyme disease by bee stings or a piece on miscarriages we get topics like the effects on the body of being struck by lightning or falling from a high place. Even some more explicitly health-related matters, such as the impact of losing your sense of smell, were engaging enough to get me past my medical squeamishness.

The only reason I can't give the collection five stars is because of one aspect of the writing style that runs throu…
