My Autumnal Love Affair with Math

I was an indifferent student of math growing up. I wasn’t bad at math exactly, but I didn’t much like the subject (except for geometry, which I took in high school from a brilliant and generous teacher who had left off being a rocket scientist–literally–so that he could teach young people). I pretty much stopped taking math as soon as I was allowed to  in high school–I stopped out at algebra III.

A couple of years later, in a spasm of optimism, I signed up to take a 7:00 am calculus class to meet my math requirement in my freshman year of college. I was influenced in this fool’s errand by one of my heroes, my writing professor Tom Lyon, whose hypoglycemia obliged him to teach at 7:00 and 8:00 am exclusively. I believed that something would blossom in me, and I would develop into the scholar and writer I was destined to be, a scholar and writer like Tom Lyon, if I got up every morning for calculus in the early hours.

Alas, my 7:00 am calculus teacher was no Tom Lyon: I remember her as earnest and competent, but not particularly skilled or experienced as a teacher. Probably, given that I was a freshman at a land grant university in a 7:00 am calculus class, she was a relatively new graduate teaching assistant. More importantly, what seeds of knowledge she sowed my way fell on rocky ground, or weedy ground–I remember not a lick of calculus from that class. Practically my only memory of that whole term was one morning watching the morning sun stream into the room late in the quarter and feeling the joy of being an 18 year-old in springtime.

Somehow I managed to pass that class despite all the time I spent gazing out the window. And 25 years later, somehow I managed to get a master of science degree in environmental science without much knowledge of calculus. I knew enough to be able to recognize that something was a calculus problem–the same way I might recognize that the people next to me are speaking Portuguese–but as for using calculus to model a problem or make a useful prediction about the world, the little glyphs and grammars of differential equations were utterly alien to me.

The gaps in my math knowledge were worse than this, actually: I remember as I was gathering the last data for my thesis that my classmate Alison Jacobs had to explain to me the formula for the slope of a line (y=mx+b) for about 30 seconds before I realized that she was talking about something that I had studied for months and months in junior high school. It comforted me a bit to learn later that the great E. O. Wilson had gotten his PhD in biology at Harvard without calculus–in Letters to a Young Scientist he talks about sitting in calculus class as a 32 year-old assistant professor, trying to atone for his crime of omission. But for me, it has been hard to shake the sense that however well I might use words to describe the thicket of the world,  I’ll never know the trails by which I might, using math, penetrate to the heart of things.

I had to climb over my own emotional palisades, then, to set out on a journey to teach myself calculus at age 45.  For me, coming back to differential calculus via Khan Academy has felt less like atonement and more like the discovery that someone I had regarded as homely in high school showed up at the 30 year reunion looking like a knockout. Somehow over the thirty years since I first sat in that 7:00 am calculus class, I have discovered that I’m in love with mathematics.

So far as I can tell, there’s no direct benefit to me in learning calculus or any other kind of math. No matter how good I may get at it in middle age, there will always be others around me who know math better and who use it more naturally than I. And what would I use calculus for anyway? I’m no better an English teacher or outcomes assessment specialist because of it. One could argue that I’m a worse English teacher because of it, opportunity costs being what they are–every hour I spend learning about limits and differentiation is an hour I don’t spend honing my knowledge of composition theory or something else I might actually use in the classroom.

But I don’t want to stop myself: I study math because math has become beautiful to me. Perhaps it seems more beautiful to me because it has no obvious use to me. I’m long past the spring term of my life now. Perhaps I can love math now because “the heyday of the blood is tame”–though in so many areas of life I feel I am entering a second youth, or even a long-delayed first youth. I never became, never will become, the scholar that Tom Lyon was in my life. But I’ve come back to scribbling out derivatives at 7:00 in the morning as I did when I was 18. The morning sun in springtime fills me with a different kind of joy.

To be a modern human is to contend with loneliness.

While this insight has been with us for decades or even centuries, it’s only recently that a body of research around the causes of loneliness, as well as its effects and its cures, has started to catch the public imagination.

Folks like Kafka and Camus seemed to assume, in the previous century, that loneliness was simply fundamental, part of the warp and weft of human existence. Today, though, researchers have begun to argue that loneliness is no more basic to human existence than tuberculosis–that, in fact, loneliness is a medical condition that can be prevented and cured.

The January issue of Scientific American has an article on loneliness that really spoke to me, perhaps because I was so lonely for so much of my youth. The author, Francine Russo, argues that in much the same way that the disease of consumption was medicalized and clinicalized into tuberculosis, we may be in the process of reconceiving loneliness as a treatable and preventable disease rather than a central reality of the human condition. For an artist like John Keats in the early 19th century, tuberculosis and loneliness were existential threats that he spent his life and work grappling with. Today, TB is (for many people in the developed world, anyway) something that one is vaccinated against.

But what vaccine is available for loneliness? Russo suggests cognitive behavioral therapy (CBT), a technique which has had deeply positive effects on my own life. And yet, in spite of my having experienced both chronic loneliness and CBT first-hand, I lacked the imagination to conceive of loneliness as a disease rather than a consequence of my very flawed character.

The other thing that dawned on me as I read the article was just how often I write about lonely characters in my stories. I just signed off on the galley prints for my latest story, “Potosí,” and realized that the main character spends a good deal of the story in utter solitude. Just like Miranda in “Full Fathom Five,” Epic in “Proteus,” and Sandra in “Lamp of the Body.” Stories with well-adjusted characters and lots of friends seem to be more rare with me.

As with all things Scientific American, the print article isn’t available online, but this closely related SciAm blog post is.

 

What Would You Call a Martian Highball?

I’m working on another hard sci fi story again. It’s a genre that I often make a conscious effort to branch out from–part of me feels much more drawn to writing absurdist Borgesian stories, or “The New Weird,” or whatever it’s being called these days. Yet something else draws me back, again and again, to writing hard science fiction, the stuff of space elevators and pressure domes and transhumanism.

One thing about hard sci fi that makes me feel out of my depth is the sheer volume of research that a serious hard sci fi reader expects from a story. And the research is wide ranging: it doesn’t matter whether I happen to know a little about genetic engineering; a good hard sci fi story also demands that I know something about AI and cryptography and planetary physics and orbital insertions.

That’s part of the fun, being able to research Martian concrete one day and asteroid mining the next. It’s also a little daunting to read the hard sci fi work of some of the current masters, folks like Linda Nagata and Ian McDonald and Gwyneth Jones, and see just how deeply researched their futures are, to see how offhandedly they predict something transformational about humanity 200 years in the future and make me wish I had thought of that.

Here’s a simple, dumb example. I’m writing a story set on a Mars colony between 100-200 years in the future. What do people drink there? I have a scene set in a bar, a kind of hangout that might remind people of an underground dive full of beer and curly fries. But it’s occurred to me in the last day or so that beer is a highly unlikely drink for colonists living under pressure domes on Mars: any staple crops like wheat or barley or oats would very likely be used for solid food, not beer. I’m fairly confident people will still want to drink alcohol 200 years in the future on Mars, but if it’s Martian hooch I would guess they’ll want something that yields a lot of alcohol from a relatively small biomass. What would that be? Fruit brandy? Potato vodka? Mezcal?

I still like the idea of a bunch of Martian undergrads downing beers and curly fries, so I may just leave those details in even though they make little sense. One of the characters in the scene is happy to see a Kentucky Bourbon on the menu–I suppose any society that can send 60,000 emigrants to Mars can also export Kentucky Bourbon, which makes more sense than exporting kegs of Earth beer over months and months and at fantastic weight. I’m not sure what to call the cocktail the character orders. Right now I just call the drink an offworlder, which seems a decent enough name, but I’m hoping to find a name with a little more zazz.

What do you think? What would you call a Martian cocktail made with Kentucky Bourbon, perhaps distantly related to an old-fashioned?

Tabby’s Star Update!

I learned over the weekend that Tabby’s Star, which I posted about recently, has just undergone (or is still undergoing) one of its unpredictable and so-far inexplicable light fluxes!

Someday the Tabby’s Star mystery will be known, and it almost certainly won’t be aliens. But it’s exciting to watch an entire scientific community train its eyes on one very distant star with bated breath.

Meditations on Tabby’s Star

This month’s issue of Scientific American has a good article summarizing the mystery of Tabby’s Star. (it’s behind a paywall, but this SciAm blog post has a rundown of the discovery). I remember talking briefly about Tabby’s Star in fall of 2015 during a reading. I remember thinking at the time that the mystery of it all would be batted away soon enough, that the star’s mysterious dimming pattern would be explained mundanely–perhaps invoking some novel phenomenon which would excite astrophysicists, but which would not become the subject of any science fiction stories to come.

A year and a half later, no such invocation has yet appeared. Humanity has discovered a star whose light emissions defy every existing rational explanation. That’s big. For me as a science fiction writer, it’s exciting to hear serious astronomers considering the possibility of the star’s mysterious dimming as the result of orbiting alien megastructures. I have to remind myself that the extraterrestrial intelligence explanation is really no more plausible than any of the explanations that do not depend on aliens–swarms of comets, a circumstellar disc, an orbiting black hole.

Whatever the explanation turns out to be–and I will say here what I said in 2015: I don’t think it’s aliens–the mere fact that an alien megastructures explanation is being considered seriously fills me with glee. It is the nature of human intelligence to reach out in all directions, seeking fellowship with like minds. Whether we do this by putting up a profile on OkCupid or a handprint on the walls of Lascaux, we are seeking fellows. I wish that Tabby’s Star, over a thousand light years away, is flocked with gigantic solar panels, because such a project could only be undertaken by creatures who–however more powerful than we they may be–think in ways that we can recognize.

Much of my own fiction has revolved around this idea. Perhaps all of it has. But two stories of mine especially, “A Murmuration of Starlings” and “Full Fathom Five,” are devoted to the longing of intelligent creatures to connect with one another. And I know I have not exhausted the subject–perhaps there is another such story slouching towards the Bethlehem of my keyboard this year.

 

I Marched for Science

March for Science2

Photo credit–Carlyn Eames

I’m not a professional scientist. I do have enough training to work as a lab tech if there’s ever some neo-Maoist Cultural Counter-Revolution where we’re all rounded up and forced to work in research facilities–it goes without saying that that won’t be happening during this administration. I’d be reluctant to call myself a scientist because I have published no peer reviewed papers, and my field work is competent at best (and often in graduate school I wasn’t at my best).  Having said that, I have actually worn a lab coat and safety goggles as a part of my job–for a week here and there, anyway–and I  have all the love for the scientific enterprise that an enthusiastic amateur science fiction author can have.

Across the republic, the streets were filled with people like me last Saturday at the March for Science. Well, based on the signs people were carrying, I’m sure that a lot of the marchers were bona fide scientists–at least bona fide lab techs and grad students. And, while there has been a healthy debate within the sciences about whether this kind of public advocacy is helpful or harmful to the cause of science, put me down as one who believes it’s valuable for scientists and science-lovers to stand up and be counted.

There has been push-back from some scientists–this article at Slate is a typical example–that the march was an orgy of uninformed and misinformed pro-science good-feelery from non-scientists. That is, according to Dr. Jeremy Samuel Faust, the folks marching mostly don’t understand science enough. If marchers did understand the state of science, with its almost guild-like patronage system, its rampant data mining and cherry picking, its Potemkin peer review, they wouldn’t be so eager to draw up witty signs and march in its defense.

Faust does have a point: I suspect few of the people on the march this weekend understand what statistical significance really refers to, and even fewer would be ready to talk about the many misuses of p<.05 that researchers engage in because they’re trying to score a publication (or, more likely, because most scientists are not statisticians and often use statistical tools in ways they were not intended).

And yes, that’s a problem. But that’s not what the march is about. One can support the scientific enterprise, be willing to march in the rain for it, without knowing everything about science. None of the marchers, even the scientists, have a full understanding of all of the sciences humans engage in. The geologists on the march don’t know any more than I do about high energy physics, and the high energy physicists know less about environmental biology than I do.

Many of the scientists out there, even the duffers like me, know that there are deep problems with the sociology of science, with the misuse of methods and publication and statistical analysis. But something the marchers all had in common, scientists and non-scientists alike, was a support for the idea underlying science: that the scientific method can be used to describe our environment and make useful predictions. Faust is right that the scientific method is a roundly abused idea even within the sciences, to say nothing of non-scientists. But one can love and support a good idea without understanding it fully.  Whether any individual marcher can be picked out of the crowd and made to follow the scientific method to Dr. Faust’s satisfaction is beside the point.

The scientific enterprise is flawed, just as representative democracy is flawed. I marched because I believe in the idea of science (and, for that matter, representative democracy). The way to reform the institution of science is the same as the way to reform the republic: it will be saved by people who care for and love those institutions. Science and civil society won’t be reformed if we roll over when the administration attempts to hobble the EPA or reverse even modest US actions to counter climate change.
