It sounded like the densest of abridgements: five days of excerpts from Reality Is Not What It Seems: the Journey to Quantum Gravity by the Italian theoretical physicist Carlo Rovelli (week beginning 28 November, 9.45am). Swarms of quantum events where time does not exist. Cosmology, meteorology and cathedrals of atomism. Leucippus of Miletus and lines of force filling space. Very few of us listening could have understood what was being said. Instead, we just allowed it to wash over, reminding us that there are more things in heaven and earth, Horatio.
Perhaps once or twice, as the week progressed, token attempts were made to check that everybody was keeping up (“So, the number of nanoseconds in a second is the same as the number of seconds in 30 years”) – or to encourage listeners to picture themselves as part of an experiment (“Imagine I’m on Mars, and you were here . . .”). But generally it was utterly airtight, the reader, Mark Meadows, doing a good job of keeping his voice at a pace and tone uncondescendingly brisk, flattering us that nobody was scratching their head (“The speed of light determined by Maxwell’s equations is velocity with respect to what?”).
It was my favourite radio book reading of 2016. Not because I learned a single thing I could repeat, or might realistically mull over, but because it sounded like a brief return to something that has declined so much over our lifetimes – knowledge as part of a function of a media flow.
It’s that old idea that something might be there for your betterment. When we were exposed to just four channels on television especially, and forced to stay on them, we got into astronomy and opera and all sorts of stuff, almost against our will. (Rigoletto? Jesus. Well, there’s nothing else on . . .) The programme was marvellously and unapologetically impenetrable, as the days and chapters piled up relentlessly (“We are immersed in a gigantic flexible snail shell”). What this adaptation comprehended was that we don’t actually want someone explaining Einstein to us. What is much more compelling – more accurate and clever – is simply to show what it’s like in other people’s brains.
