Linda Schweizer - Four Way Interview

Linda Schweizer earned an MA in mathematics and a PhD in astronomy at UC Berkeley, with the visual arts and dance as her other passions. She observed southern-hemisphere galaxy pairs with several telescopes in cold dark domes in Chile, then modelled, analyzed, and published her work in 1987. Those papers on the statistical and dynamical modelling of dark matter in binary galaxy halos were, she says, just a small stone in the mosaic of our growing understanding of dark matter. A Carnegie Fellowship in Washington, DC, was her first science job. By then, she had her second daughter in the oven— with two more daughters to follow, and she turned her focus to properly preparing them for life. After 15 years, she returned to the world of astrophysics. After a brief stint in External Affairs, she taught science writing to undergraduate students at Caltech and loved it. She was a Visiting Scholar at Caltech while researching Cosmic Odyssey, an insider’s history of one of the greatest eras in astronomical development. Her passion for astronomy began at an early age with numerous trips to Griffith Observatory in Los Angeles, where she was fascinated by how scientific concepts were represented by models, motions, and large-scale graphics. Her creds include once designing and producing unique hand-made posters for the San Francisco Opera House, writing an award-winning booklet on telescopes and astronomy, and being awarded a Rockefeller Foundation grant to support the research and writing of Cosmic Odyssey.

Why astronomy?

Astronomy is the perfect amalgamation of physics, chemistry, biology, and art. I love first understanding complex ideas in physics or mathematics, and then visualizing them as art or a dancer’s movement. There is so much variety in astronomy: in which colour do you want to examine the universe? Infrared light from cool, dusty objects? Ultraviolet light from luminous quasars or newborn galaxies at the edge of the universe? Do you want to theoretically model the universe, or gather data on it?  Do you want to study the electron degeneracy deep inside collapsed stars, or the gaseous filaments of the cosmic web stretching across billions of light years? Astronomy is very intimate and resides within each of us for our entire lives as we grow, learn, emote, and love under its mysterious canopy. It connects us to each other and to all life on earth.

Why this book?

Ever since my graduate work, I was struck by how big a role Palomar played in the development of astrophysics in the 20th century. Only later I realized why. Palomar is a 'Goldilocks' observatory! It was the right size to do some serious work; it appeared at the right time—in the mid-twentieth century—for war technology to yield infrared and radio detectors that opened new windows on the universe; and it was in the right place, nestled in pristine high mountains not too far from Caltech, Mount Wilson Observatory, and the Jet Propulsion Laboratory. Working at both Carnegie and Caltech, I got to know many astronomers who made fundamental discoveries at Palomar, and I was in a unique position to interview them and build the backstory of Cosmic Odyssey. I took the opportunity to interview more than 100 people to portray a behind-the-scenes view of how science is done by imperfect, yet inspiring, scientists. Most people only see the final announcement of a discovery and the publicity that goes with it. They miss out on the raw images that yield new insights, and the rivalries and collaborations that fuel scientists’ ambitions. In addition to digging into the science and history of astronomy at Palomar, my book also lifts the curtain on the process of discovery, and I hope it will inspire a new generation of young scientists. 

What's next?

To keep the story flowing and focused while writing Cosmic Odyssey, a lot of material was left on the cutting-room floor. Not only scientific material, but fascinating human stories: the artistic maverick who grows perfectly-formed orchids while observing mangled mashups of galaxies—and pries open the field of galaxy evolution; the old astronomer who miraculously recognizes the feeble lines of radioactive technetium in a stellar spectrum crowded with atomic and molecular lines—and proves that nuclear furnaces, not the big bang, produce most of the chemical elements. So, maybe there’s another book waiting in the wings. I am also drawn to writing a similar book for children

What's exciting you at the moment?

For the past ten years, I’ve been focused on the world I’ve built within my book, Cosmic Odyssey. Now, I’m looking forward to exploring everything else in the universe!

It's On You - Nick Chater and George Loewenstein *****

Going on the cover you might think this was a political polemic - and admittedly there's an element of that - but the reason it's so good is quite different. It shows how behavioural economics and social psychology have led us astray by putting the focus way too much on individuals. A particular target is the concept of nudges which (as described in Brainjacking ) have been hugely over-rated. But overall the key problem ties to another psychological concept: framing. Huge kudos to both Nick Chater and George Loewenstein - a behavioural scientist and an economics and psychology professor - for having the guts to take on the flaws in their own earlier work and that of colleagues, because they make clear just how limited and potentially dangerous is the belief that individuals changing their behaviour can solve large-scale problems. The main thesis of the book is that there are two ways to approach the major problems we face - an 'i-frame' where we focus on the individual ...

Introducing Artificial Intelligence – Henry Brighton & Howard Selina ****

It is almost impossible to rate these relentlessly hip books – they are pure marmite*. The huge  Introducing  … series (a vast range of books covering everything from Quantum Theory to Islam), previously known as …  for Beginners , puts across the message in a style that owes as much to Terry Gilliam and pop art as it does to popular science. Pretty well every page features large graphics with speech bubbles that are supposed to emphasise the point. Funnily,  Introducing Artificial Intelligence  is both a good and bad example of the series. Let’s get the bad bits out of the way first. The illustrators of these books are very variable, and I didn’t particularly like the pictures here. They did add something – the illustrations in these books always have a lot of information content, rather than being window dressing – but they seemed more detached from the text and rather lacking in the oomph the best versions have. The other real problem is that...

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, ...
