For most of its history until fairly recent times the general pattern for Earth was to be hot with no permanent ice anywhere. The current ice age—ice epoch really—started about forty million years ago...
For reasons that are still poorly understood, at depths beyond about 30 metres nitrogen becomes a powerful intoxicant. Under its influence divers had been known to offer their air hoses to passing fis...
For the universe to exist as it does requires that hydrogen be converted to helium in a precise but comparatively stately manner. Tweak the numbers even slightly and we would not be here. Optical
Generally speaking – which is of course always a dangerous thing to do, generally speaking – Americans revere the past only as long as there is some money in it somewhere and it doesn’t mean going wit...
So the first dinosaur bone ever found was also the first to be lost.
If the global temperature rises by 4°C over the next fifty years, as is evidently possible, the whole of the Appalachian wilderness below New England could become savanna. Already trees are dying in f...
Science is about making stuff, just as much as it is about understanding stuff.

I had a hangover you could sell to science,
Wallace, King and Sanders point out in Biology: The Science of Life (that rarest thing: a readable textbook),
Rome was as wonderful as I had hoped it would be, certainly a step up from Peoria.
I passed the time browsing in the windows of the many tourists shops that stand along it, reflecting on what a lot of things the Scots have given the world—kilts, bagpipes, tam-o’-shanters, tins of oa...
Salamanders are interesting, and don't let anyone tell you otherwise.
Perhaps it would be an idea to require developers to live on their own estates for five years, as a demonstration of their superb liveability. It’s just a thought. I
