I volunteer to help science with its image makeover

Two posts from my Delicious network within the same hour: An earnest article from The Scientist about how science urgently needs better marketing, and blogger Scott Aaronson's complaint that his quantum mechanics lectures were plagiarized to sell computer printers.

There's no need to market science at all. Science sells itself. We have strong evolutionary incentives to be curious about the facts of this world we live in. Every young kid I've ever met is interested in science. They may not be interested in the way it's presented in school, but they're all interested. My favorite line from Calvin and Hobbes:

Calvin's dad: "You've read just about every dinosaur book ever written. So why aren't you doing better in school?"

Calvin: "We don't read about dinosaurs."

Little kids should be interested in dinosaurs. For nearly all of our long evolutionary history, the possibility of being eaten was a very real one. You mean there used to be giant reptiles that could eat you? What else is out there?

I will never forget the science class at Fieldston Lower when we got some pond water and looked at it under the microscope. There, among the tiny air bubbles and bits of organic crud were assorted tiny swimming beasties, some with wriggling tentacles.

The big challenge for science isn't so much the marketing as it is staying out of the way of the facts. The biggest distraction from those facts is usually the scientist's emotional tone. For example, Richard Dawkins' tone communicates two emotions very strongly. One is his genuine pleasure in his work, his most attractive quality as a writer. The other emotion is contemptuous hostility towards people who don't get it, or who are unwilling to. This hostility is Dawkins' least attractive quality as a writer. Why do I, the reader, want to subject myself to it? Even if it's not aimed directly at me, and even if it's well-motivated, hostility is ugly and offputting. Karen Armstrong complains that Dawkins is angry, he hates religion, and that's a short step from hating religious people. This is not, as Buddha would say, skillful. I would say that Dawkins has clarity without compassion (as opposed to gooey New Agers like Deepak Chopra, who have compassion without clarity.) Evolutionary theory is threatening to our most basic cultural assumptions, and the best teachers know that they have to give us time to deal.

Knowledge is disciplined imagination. Scientists need to present their ideas using the many techniques developed by artists over the years. I would say that art is the science of getting ideas into people's heads (whether those ideas are true or valid being another story.) Above all, scientists need to learn how to write. The default prose style for scientists is: Edwardian. British and German. Lots of subclauses within subclauses, long rambling parentheticals, jargon, tone-deafness for prosody. Good writing has rules every bit as rigorous and inflexible as any other technology. I recommend the rules put forth by Strunk and White: Use short, declarative sentences. Prefer plain language to jargon when possible. Introduce new vocabulary with clear definitions in plain English. When a word has several synonyms, choose the shorter and more commonly used one. Don't say 'clearly' or 'obviously'. If something is really obvious, you don't need to state it. If you find that you do need to state it, then it isn't obvious.

I'd add some writing tips of my own. Written language evolved from spoken language. Spoken language evolved from music: rhythm, dance, singing. The musicality of language is not decorative. If you want to convey information in a way that sticks, you need to be musical. Repetition is desirable because people build new concepts through rehearsal and variation. One way to make your prose more musical is to read it out loud, ideally to another person, or to your dog, cat, even your plants, whatever. You've had a lot more practice at talking than at writing. Aside from a few literary savants, everyone speaks more eloquently than they write. It's not a bad idea to tape-record yourself reading, then listen back. Clunky phrasing will leap right out at you the way it doesn't from the page.

Concepts in the brain consist, at their most fundamental level, of images of the body's state. In order to be understand a concept, you need to build a web of bodily metaphors for it. Einstein famously had the idea for relativity by imagining himself riding a light beam. Successful teachers of abstract concepts always use body metaphors. See Steven Pinker for countless examples. The further into the micro- and macroscale we go, the harder it is to find bodily metaphors. It's easy to imagine being the size of, say, a mouse; it's hard to imagine being the size of, say, a proton. Or is it? Maybe we just need better metaphors. Video games are a severely underutilized teaching tool for science. I can't think of a better way to teach quantum mechanics than to set a game at the subatomic scale, and have it obey all the real-world laws as best as we can currently mathematically model them.

We want to encourage the sense of exploration by reminding ourselves, aloud and often, that the best and most important discoveries don't always come about intentionally. The web browser was invented by Tim Berners-Lee, a particle physicist at CERN, because he wanted an easier way to share data with his colleagues at far-flung institutions. The cosmic background microwave radiation was first detected as an annoying and mysterious background noise on a sensitive radio antenna. The term 'Big Bang' was coined derisively by astrophysicist Fred Hoyle, who didn't think the theory had merit. Science is often funny and should be presented as such. The collective works of Douglas Adams are a good start. Also Larry Gonick's Cartoon History Of The Universe and Bill Bryson's Short History Of Nearly Everything.

The term 'physical law' is off-putting and misleading. The word 'law' triggers associations to human authority, suggesting that the reason you can't travel faster than light or whatever is because God says so. The concept of a law unconsciously mirrors the way that Saudi physics textbooks describe two atoms forming a covalent bond "by the will of Allah." The word 'theory' in the scientific sense is a problem, too, because it's already in common usage, and for most of us it means something specific: an untested hypothesis, a conjecture. The word 'theory' in science means almost the opposite: a mathematical description of a given phenomena, one that makes quantifiable predictions that agree with observation of the world.

Another thing that makes science needlessly difficult is when phenomena get named after the people who discovered them: the Casimir effect, the Schwarzchild radius, the Higgs field. I realize that that we have to compensate for the lousy pay in basic science somehow, and that ego-boosting helps motivate scientists to hang in there. Unfortunately, it makes it hard for the rest of us to keep everything straight. It would be helpful if scientific phenomena and theories had names that described them. Gluons are extraordinarily well-named: they glue quarks together, there's no forgetting it. A neutron star is a star made of neutrons, again, boom, the name tells you the whole story.

I like Lisa Randall's book Warped Passages because the book gives evidence of having been written by a person. I like her pop culture references and political asides and journalistic observation. I love her use of attractively rendered and laid-out illustrations. And I adore her quotes from pop songs at the beginning of each chapter, with lyrics bearing in some jokey way on that chapter's contents. For example, her chapter on symmetry begins with a quote from Simple Minds' Don't You Forget About Me: "La, la la la la, la la la la..." She also quotes Metallica and Eminem. I would love to get a look at her iPod. Jokes and pop songs, like video games, are sorely underused as a way to access abstract ideas that resist straightforward description.

Space is a difficult area for marketing. Everybody's interested in it, until they start to really learn about it. When astronauts talk about 'the right stuff', they leave the fact that if you want to go into space, you have to be in the small percentage of people who are totally immune to motion sickness. Being in zero gravity seems like it might be fun, but it also makes a normal person dizzy, disoriented and likely to throw up. Copiously. Astronauts have to have incredible proprioception and inner-ear systems, the way basketball players have to be incredibly fast. Space sickness is measured in Garns, after Utah senator Jake Garn, who parlayed his position on an appropriations committee to get a ride on the space shuttle, and, well, I'll leave the rest to the imagination. Suffice to say, if you think throwing up is gross, imagine doing it in zero gravity.

And yet. America is a pretty terrible place in some ways, but we did manage to send sixteen guys far away enough from the Earth to be able to completely cover it with their gloved thumb. Once you've learned the news that such a thing is possible, you can't unlearn it. The idea of universal human rights is a very recent historical novelty. Such a concept could scarcely have existed without the trip through the Total Perspective Vortex that modern science has put us through. Scientists tend to be secular humanists at heart, from Einstein on down, and there's a natural tendency towards healthy Buddhist acceptance that comes from contemplating the very big and very small and very old and very new. If scientists want to engage the emotions and imagination of the general public, they need to play up the the very genuine inspirational quality of their work.
