One of the best pieces of advice given to me early in my “career” was to start what my editor at the time called a commonplace book. This was just a place to store any quotations that struck me as valuable for some reason – that reason varying from the profound to the funny, or even mysterious.
Obviously the idea was to make a note of who had originated the quote and in what context. This did not always work – as in this one, for instance. I don’t know where it came from, but it’s still memorable as far as I’m concerned:
“I would feel infinitely more comfortable in your presence if you would agree to treat gravity as a law, rather than one of a number of suggested options.”
This comes under the “funny” category, in case you were wondering. But at the same time, it always made me feel a little uneasy. How many things, especially in science, do we assume are settled?
And so I was intrigued to read the other day that gravity may not be a law or fundamental force after all, but possibly something that emerges from quantum electromagnetic interactions, potentially reshaping our view of spacetime itself. I’m sure you know what that means.
Science is a funny thing. We think it means establishing facts, but in fact it depends on doubt. The first thing a scientist should do when looking closely at a theory is try to prove it wrong. If this fails, he or she has something to work with.
Unfortunately it seems to me that recently this truth has been forgotten. We collect data and come to conclusions, then forget that it is the data that (hopefully) are facts, and not the conclusions. Conclusions, or theories, are our attempts to knock the data into a shape that we understand. There is a huge capacity for error in there.
People who are not scientists don’t really get this. They really want science to be the facts. Follow the science, they say. Well, that’s OK, as long as you realise that it might be leading you in the wrong direction. Test the science, or question the science, might be the more sensible option.
Unfortunately it seems to me that schools and universities look at things wrongly. They want consensus on a particular issue, but science is not democracy. They teach the consensus as if were the only option, and everything else as if it’s a conspiracy theory.
Unfortunately, as I’ve said before – and here I delve into my commonplace collection again – the easiest and least stressful path to success is to adopt the status quo viewpoint without question. A guy called Fred Heffer wrote that five years ago.
So confusing consensus with certainty is a popular career move. It is also welcomed in the population at large, especially if you live in a democracy. And you don’t have to search far down the decades to find breakthrough theories that were resisted for years because those in charge preferred to deal with stuff they had been taught and had taught to others, whether it was right or not.
Science should be exciting, because it frequently does somersaults. But those in charge like straight lines. However, as R Buckminster Fuller pointed out, there are no straight lines in the universe. It’s a lot more interesting than that.
So maybe speed isn’t the main cause of accidents. Maybe theories of climate change are wrong. I’ll go further: they definitely are. I don’t know how, but I’d guess fundamentally. Really. That’s pretty obvious already. Take my word for it. One day everybody will say so.
