When I was at school I had a conversation with my physics teacher, Mrs Price, that truly was a butterfly effect moment. As a result of that coversation I finished up studying geophysics. At the time it was somewhat of a niche subject (come to think of it, it probably still is) but I genuinely found it fascinating (and I still do). The BBC has produced a couple of series recently that had me reaching for my text books again only to realise that I need to sit back and enjoy the Wonders of first the Solar System and then the Universe. As a quick aside, the series titles do beg the question; Where do you go next? You know, after you’ve done the Solar System and the Universe. Is there a multi-verse? Are we alone? What if it all means something? Or even worse, what if it all means nothing? (Or should that be the other way around?). Either which way, the two series demonstrate many of the things that the BBC does best and Brian Cox makes a pretty decent presenter, given that his day job is a Professor of astrophysics at Manchester University and he used to be in a (moderately successful) rock band. Oh and apparently he’s quite good looking too. Yup, he’s the kid we all used to know at school who was just too good at everything. If he didn’t come across as being such a nice chap you could really grow to dislike him.
But back to what I learnt at university: The single biggest concept that you need to get your head around in geophysics is “time”. Geology exists over such a long time that it makes your head hurt and no amount of analogy of compressing the lifetime of the earth into a single day makes it any easier. And in a somewhat related fashion, the 2nd biggest concept to get your head around in the bit of geophysics that I finished up studying is “space”. Which does mean that according to Einsteins’s theory of general relativity actually there is only 1 concept because of that mind-bending concept of space-time, but that’s a subject for another day.
We, on this small, blue dot spend our days busily doing things and sometimes we fail to notice the passing of time. Sure, on a geological scale we are just a blip but that shouldn’t stop us noticing the changes going on all around us. I am fortunate that I have 2 sons and 2 daughters who seem to change each and every time you turn around to look at them. And every now and then we need to take the time to stop and realise the things that are precious to us and saviour them.
I was browsing back through some old photographs of my kids (thanks to digital photography that’s a lot simpler than it used to be) and it too my breath away to see the changes in them. Of course, we know that they grow, but if you are lucky enough to see your children every day then you probably get totally consumed with the minutae of the day to day routine. But we shouldn’t. We should find time. It’s worth it, I promise you.
