Neil deGrasse Tyson on Scientific Literacy, Education, and the Poetry of the Cosmos

By:

“Science is a way of equipping yourself with the tools to interpret what happens in front of you.”

“People,” lamented Richard Feynman in 1964, “I mean the average person, the great majority of people, the enormous majority of people — are woefully, pitifully, absolutely ignorant of the science of the world that they live in.” In the half-century since, we’ve sequenced the human genome, put a man on the moon and rovers on Mars, confirmed the existence of the Higgs “God particle” boson, and achieved innumerable scientific miracles, small and large, that enhance our daily lives in fundamental ways. And yet, bad science spreads, good science journalism is fighting an uphill battle against media reductionism and distortion, and the general public remains as just as woefully and pitifully distrustful of or, worse yet, unconcerned with science as in the Feynman days.

In this fantastic conversation with Stephen Colbert, Hayden Planetarium director Neil deGrasse Tyson — passionate crusader for space exploration, eloquent champion of the whimsy of the cosmos, modern-day Richard “Great Explainer” Feynman — brings his characteristic blend of sharp insight, quick wit, and unapologetic opinion to the issue of scientific literacy and how it relates to everything from education to government spending to morality.

Highlights below, though the entire hour-long conversation — including the most brilliant and hilarious James Cameron Titanic critique you’ll ever hear — is more than worth the time.

On the ethics of discovery vs. the broader morality of application:

We are collectively part of a society that is using or not using, to its benefit or its detriment, the discoveries of science. And at the end of the day, a discovery itself is not moral — it’s our application of it that has to pass that test.

On the misunderstanding of science:

[Science] is distrusted not because of what it can do, but because people don’t understand how it does what it can do — and that absence of understanding, or misunderstanding, of the power of science is what makes people afraid. … Just because you don’t understand it, doesn’t mean it’s bad for you — go figure out how it works! That’s why we need a scientifically literate electorate — so that when you go to the polls, you can make an informed judgment and you can draw your own conclusions rather than tune into a particular TV station to have your conclusions handed to you.

On the poetry of astrophysics:

Some of the greatest poetry is revealing in the reader the beauty of something that is so simple you had taken it for granted. That, I think, is the job of the poet. The simplicity of the universe, if it doesn’t drive you to poetry it drives you to bask in the majesty of the cosmos.

On what’s wrong with education:

Our academic system rewards people who know a lot of stuff and, generally, we call those people ‘smart.’ But at the end of the day, who do you want: The person who can figure stuff out that they’ve never seen before, or the person who can rabble off a bunch of facts?

A brilliant addition to history’s best definitions of science:

[Science] is a way of equipping yourself with the tools to interpret what happens in front of you.

On our broken yardsticks for assessing the value of scientific research:

Today, you hear people say, ‘Why are we spending money up there when we’ve got problems on Earth?’ And people don’t connect the time-delay between the frontier of scientific research and how it’s going to transform your life later down the line. All they want is a quarterly report that shows the part that comes out of it — that is so short-sighted that it’s the beginning of the end of your culture.

He goes on to point out that people grossly misperceive how much is actually being spent “up there,” assuming anywhere between 10 and 15% of taxpayer money, whereas the real number is a mere 6/10 of a penny on the tax dollar, or 0.6%. The solution:

The greatest need is to be able to have the foresight necessary to make investments on the frontier of science even if, at the time you make those investments, you cannot figure out how that might make you rich tomorrow.

Finally, when Colbert asks the grandest cosmic question of all — why there is something instead of nothing — Tyson answers with a brilliant haiku-esque retort that hints at the power of ignorance as a tool of science:

Words that make questions
May not be questions
At all

Tyson’s latest book, Space Chronicles: Facing the Ultimate Frontier (public library), is a must-read.

The Science of Procrastination and How to Manage It, Animated

By:

This is where you insert the meta-joke about what else you’re actually supposed to be doing this very moment.

From AsapSCIENCE — who have previously brought us the scientific cure for hangovers, the neurobiology of orgasms, and how music enchants the brain — comes this illustrated explication of the science of procrastination and how to manage it, a fine addition to these five perspectives on procrastination. Among the proposed solutions is the Pomodoro technique, a time-management method similar to timeboxing that uses timed intervals of work and reward.

Human motivation is highly influenced by how imminent the reward is perceived to be — meaning, the further away the reward is, the more you discount its value. This is often referred to as Present bias, or Hyperbolic discounting.

For a more metaphysical take on the subject, see the fantastic anthology The Thief of Time: Philosophical Essays on Procrastination.

The Best Science Writing Online 2012, In a Print Book

By:

A far more brilliant and necessary idea than it first appears.

At first, the idea of publishing some of the web’s finest journalism in a print book might seem counterintuitive, if not downright absurd — after all, half the beauty of online journalism is the magical Rube Goldberg machine of references, strung together via hyperlinks that offer riffs and context without the cumbersome expository bulk of text. So what happens when you strip the writing of its linked context, of the dynamism of hypertext, and confine it to the static printed page?

In The Best Science Writing Online 2012 (public library), editors Bora Zivkovic and Jennifer Ouellette demonstrate precisely what happens — and it’s something rather curious and whimsical.

Once you’re able to get past seemingly anachronistic footnotes awkwardly compensating for the linklessness, you find yourself immersed in the writing in a way that the web’s blinking, demanding, ad-infested pages never quite allow. But, most importantly, you begin to see connections between critical issues, to understand how things fit together and why, as Charles Eames once observed, “the quality of the connections is the key to quality per se.” And therein lies the magic of the anthology’s thoughtful curation — a potent mix of critical analyses, witty personal reflections, absorbing feature profiles, illuminating commentary on the intersection of science and social policy, and even long-form investigative journalism, covering everything from the last space shuttle launch to fluid dynamics to gender politics.

In “The Renaissance Man,” the inimitable Ed Yong shows us that rigorous science journalism and exquisite long-form feature profiles can coexist, and when they do, it’s a thing of beauty:

Aiden is a scientist, yes, but while most of his peers stay within a specific field — say, neuroscience or genetics — Aiden crosses them with almost casual abandon. His research has taken him across molecular biology, linguistics, physics, engineering and mathematics. He was the man behind last year’s ‘culturomics’ study, where he looked at the evolution of human culture through the lens of four per cent of all the books ever published. Before that, he solved the three-dimensional structure of the human genome, studied the mathematics of verbs, and invented an insole called the iShoe that can diagnose balance problems in elderly people. ‘I guess I just view myself as a scientist,’ he says.

His approach stands in stark contrast to the standard scientific career: find an area of interest and become increasingly knowledgeable about it. Instead of branching out from a central speciality, Aiden is interested in ‘interdisciplinary’ problems that cross the boundaries of different disciplines. His approach is nomadic. He moves about, searching for ideas that will pique his curiosity, extend his horizons, and hopefully make a big impact.

‘I don’t view myself as a practitioner of a particular skill or method,’ he says.

[…]

Aiden naturally gravitates to problems that he knows little about. ‘The reason is that most projects fail,’ he says. ‘If the project you know a lot about fails, you haven’t gained anything. If a project you know relatively little about fails, you potentially have a bunch of new and better ideas.’ And Aiden has a habit of using his failures as springboards for success.

In “On Beards, Biology, and Being a Real American,” molecular biologist Joe Hanson, everyone’s favorite Feynman of the Tumblr era, brings his signature blend of the personal and the universally insightful to explore the bacterial ecosystems that inhabit the token signifier of hipster street cred, painting, as he always does, science as as anything but boring. Amidst the fascinating microbiology, you also find such priceless sentences as:

Unsurprisingly, when a live chicken is rubbed across an unwashed beard containing a lethal titer of avian viral particles, then ground up in a blender and injected into fertilized eggs, the rates of survival are not good. Beard-wearing scientists must take care to ensure that they do not repeat this extremely precise and odd sequence of events, lest they ruin dozens of perfectly good eggs.

But the anthology’s greatest curatorial feat is the purposefulness with which it debunks the myth that science is dry, passionless, objective, and devoid of emotional investment. Take, for instance, Scientific American’s Christie Wilcox, who in “Why do women cry? Obviously, it’s so they don’t get laid” takes MSNBC’s Brian Alexander’s appallingly sexist pseudoscience reportage head-on and brings to it with equal force the dual lenses of hard science and eloquent, unabashedly opinionated analysis:

Alexander’s reporting of the actual science was quick and simplistic, and couched in sexist commentary (like how powerful women’s tears are as manipulative devices). And to finish things off, he clearly states what he found to be the most important find of the study:

‘Bottom line, ladies? If you’re looking for arousal, don’t turn on the waterworks.’

It’s no wonder that the general public sometimes questions whether science is important. If that was truly the aim of this paper, I’d be concerned, too!

[…]

Of course, Brian Alexander missed the point. This paper wasn’t published as a part of a women’s how-to guide for getting laid. Instead, the authors sought to determine if the chemicals present in human tears might serve as chemosignals like they do for other animals — and they got some pretty interesting results.

She goes on to cite a number of studies that suggest alternative, more complex evolutionary explanations, then concludes:

Why do I care so much? It’s not just that they got it wrong. It’s that their interpretation of research isn’t labeled as opinion. It’s that the vast majority of people who have any interest in science news are going to read inaccurate (if not downright insulting) news articles and think studies like this one are either misogynistic or frivolous. It’s that journalists like Brian Alexander undermine good science for the sake of attention grabbing headlines. And as a scientist and a writer, I am doubly insulted.

The rest of The Best Science Writing Online 2012 is just as stirring and stimulating — do yourself a favor.

The Science of Orgasms and Your Brain on Porn

By:

Inside the complex tangle of biology and behavior that shapes our relationship with and experience of sex.

We’ve already explored the origins of sex, the neurochemistry of heartbreak, and how drugs affect desire. But what, exactly, happens in the brain when the body belts out its ultimate anthem of sexual triumph? Count on creative duo Mitchell Moffit and Gregory Brown, better known as AsapSCIENCE — who have previously explained how music enchants the brain and what science teaches us about curing hangovers — to break down the body’s response during orgasm:

But what about sexual experiences that don’t involve direct contact with a partner? What happens inside the brain then is arguably even more intriguing. In this talk from TEDxGlasgow, physiology teacher Gary Wilson peels the curtain on the complex scientific processes that accompany, and perpetuate, the world’s addiction to pornography. Specifically, he looks at how the Coolidge effect fuels internet porn:

For more on this ceaselessly fascinating tangle of biology and behavior, see the recently released The Chemistry Between Us: Love, Sex, and the Science of Attraction by neuroscientist Larry Young and journalist Brian Alexander, who take us inside the living brain to explore how its neurotransmitters, hormones, and circuits shape the very behaviors we find ourselves most invested in.
