I should really be commenting on all the fascinating physics stuff, as a physics graduate, but I can't get my head around it all either. I still don't know how planes fly or how mobile phones can possibly work.
But all I can think of is how do cats find their way home (i.e. their new home) when their owner moves house? They don't get a map with the new route, or time to practice, they just do it. Also, rabbits. Our next door neighbour asked us to keep an eye on and feed their rabbits when they went on holiday last year. It was the first time they'd asked, having lived next door for ten years, and the rabbits had been there at least five years. Literally the minute we were in charge, the rabbits found their way into our garden, having never ever done this before, and then out through a gap in our fence onto the path that goes out of the estate. Why why why did they make this decision on that day????!!!! Thankfully they came back (equally mystifying how they did that) and we got them back into their cage and blocked the hole between our gardens which had been there for years and years and years........
I've just been out to the car and opened the boot and my son's coat was there. I have a child! In fact I have two. It's mad that I am 'mam' to these people.
What are thoughts, really?
And back to physics. How on earth have we, as nothing more than advanced monkeys, managed to work out so much about how the universe works. We're just tiny daft things on an insignificant planet, but we know so much about the insanely massive universe and its rules. But, how do the scientists and engineers know what machines they need to build to find out all this information? I've visited CERN a few times, and honestly cannot fathom where you start with building that. How do you know what is needed, what to make it from, which cable to join to something else? It is crazy.
When was the first human baby born? One day it must have been coming to the end of the previous species and the final baby was born, then the next day the first official human baby.
Oh and I still don't understand magnets.
