are so many, and come so rapidly, one after another, that it's easy to become a little blasé about them.
I'm probably right at the head of the queue where that's concerned, but just occasionally something happens that brings home to me how astonishing some of our advances are. That happened just now, when I read about how Nasa's Curiosity Mars rover has calmly drilled a hole in a rock on a planet that's currently around 60 million miles from earth, and sent us a high-definition image of the hole to prove it.
The technologies leading up to this seemingly simple act are even more amazing when you remember that it is just over 100 years since the first flight of a heavier than air machine.
The dust from the hole is now being analysed, and soon we'll know how that rock was formed, and when.
Something to wonder at over the Sunday morning bacon and eggs.
It's a nice neat hole though isn't it? When it fills up with mud will it be a black hole in space?
Seriously, I think the money could have been better spent on Earth improving the lives of its inhabitants. No doubt the answer will be that the money spent on technology now will improve our chances and the lives of earthlings later on. I suppose it is a matter of priority. But I think they have got their priorities wrong.
