The problem with going to Mars (of which the Moon, I am told, is a part) is that it’s not just a long way off, it’s also kind of desolate. No atmosphere to speak of. Barren. Waterless, except a bit. Was once a fertile place. Then it suffered climate change. All that was about three … More Let’s go to Mars (of which the Moon is a part)
I woke this morning to news that Notre Dame cathedral was afire. It shocked me; this is one of the world’s great buildings of all time. I’m glad the French were able to save at least part of the structure. The story took me back a dozen years to the day when my wife and … More Notre Dame cathedral before the fire

Actually, I think ‘Nazi’ is great term to describe such behaviour. Why? Because the underlying forces involved are the same.

If both Special and General Relativity didn’t work precisely as Einstein said it did, GPS would be far less accurate than it actually is. Like, way off, meaning those auto-drive cars wouldn’t even get to the right road. Or any road. And we’d all be lost. Let me explain. GPS works by very precise distance … More How GPS finds you and lets Google send you adverts
