what’s that thing called science?

There are people I know who profess no interest in science. Not because they lack intelligence – after all, professing is what professors do, en it? And not because they’re religious – remember Stephen Jay Gould’s silly NOMA (non-overlapping magisteria)? It snared him an audience with the Catholic Papa, and perhaps that’s what it was all about, but the fact remains that The Church is a totalizingly magisterial organisation and always will be.
So, no, it seems to be more about C P Snow’s old notion of ‘the two cultures’. Some quite smart people are happy to be scientifically illiterate and find the whole thing a bore, or worse. A fellow teacher of mine – I used to teach EAP (English for Academic Purposes) to NESB students vying for a place at an English language university – once quoted one of Newton’s laws at me – F=ma perhaps – to prove that it was virtually all kindergarten stuff. I mean, how E=mc² is that? She did know something about Thomas Kuhn’s highly questionable concept of paradigm shifts, which she used as proof that it was all just high-falutin fashion.
So, in defence of science, let me break it down. Science is curiosity. Science is wonder. Like wondering why the sky is blue – when the sun is visible. Why the moon changes shape in the sky. Why some days are hot and some are cold. Why we grow old. Why some people are good to look at, others not so much. Why we get sick. Why we get hungry. Why we get tired. Just about everything is a cause for wonder, and science tries to satisfy that curiosity, though it seems so often to open up more questions. Do all creatures see the same sky that we do? Can all creatures even see? What exactly is seeing? How do eyes work? How long is it possible to live? Why don’t cats and dogs live as long as we do, barring accidents? And so on and so on ad infinitum. Science just never ends. I wonder why?
Here’s my little ‘come to science’ story, probably a just-so story. I was an avid reader from childhood – mostly fiction, but also encyclopaedia entries (mostly history, and biographies from Albert Einstein to Adolf Hitler) and a bit of that soft and very malleable science called psychology, because my mother worked in a mental hospital. And so it went, through to my early to mid twenties when I happened upon a novel by Thomas Mann, called The Magic Mountain. Its central character, Hans Castorp, was about my age, and had been sent to an alpine sanitarium, in an attempt to cure his consumption. He encounters some lively characters, and engages in deep discussion and contemplation, on politics, the nature of time, the origin of life, and even non-life – why is there something rather than nothing? And it was these last, more or less scientific questions that seemed to flick a switch in me. It inspired me to buy my first fully scientific book – The selfish gene, by Richard Dawkins – and a copy of Scientific American every month for the next two or three years, before switching to New Scientist, and then to the various science podcasts and videos available these days.
I may be exaggerating this ‘come to science’ moment – we like to turn our memories into neat narratives – but I do feel that my greater interest in scientific problems and solutions since that time has helped me to ‘rise above myself and grasp the world’, a term attributed to Archimedes which has resonated with me since I first encountered it, not so long ago. And there’s so much about our world that we haven’t yet grasped, and are just discovering. We identified our first exoplanet in the 1990s, and now we know of around 6,000 (in saying ‘we’ I’m reminded again of my teaching colleague, who responded contemptuously to my use of the pronoun – ‘ “We”? – what part did you play in all that?’), and we learned with some certainty in 2010 that Neanderthals and Humans got it on together from time to time. And the Vera Rubin observatory/telescope, which has just come online, will doubtless bring a harvest of new discoveries and conundrums.
And of course the world of science is also a world of scientists, in a multitude of fields, each one more fascinating than the next. These fields are, I must admit, a welcome escape from the horrors, tragedies and stupidities of much that we call global politics, and the workers in those fields seem so much happier in their bubbly spheres of interest. I would have liked to have been one. Better even than being a bonobo, maybe… but I love the way they swing….
