What an odd-looking person this Freeman Dyson is. His nose is long, his ears stick out, his smile is tentatively friendly, but what to make of those eyes? Dyson is hard to describe: he’s not like anyone you’ve met before and whatever he says is not what you’ll expect him to say. He’s spent his […]

This picture is what the sky really looks like. Click on it. It’s the biggest digital color picture of the sky, the part called the Northern Galactic Cap, and it’s taken years to produce; it’s a trillion pixels, a terapixel and — says the press release from the Sloan Digital Sky Survey — to see […]
I swear, you could get a good start at being a practicing geologist, just from looking at maps. These lovely looping patterns are a satellite’s view of some mountains in southeastern Oklahoma. They are the Ouachita, pronounced Wachita and mispronounced Wichita. I’m fond of the Ouachita – they’re sleepers. And given what went on underneath […]

That is, heat rises and cold falls, updrafts and downdrafts, up in the middle and down at the sides: a cell of convection. This convective cell is called a supercell and […]

Click on About for more about Cassandra, and then go find her website to […]
I grant this is just straight-up astroporn but let’s try to make it legit. It’s a picture taken in 2009 by the Hubble Space Telescope of NGC 3372, the great nebula in the constellation Carina, which is in the sky over the southern hemisphere. “Nebula” is an old astronomical word that has referred to a […]
I thought I’d made the case against parasitic wasps with evidence and eloquence. I thought that would be the end of it. But no: counter-arguments were made (even if insects did evolve first, Josie, I can still feel superior), gauntlets thrown down, aspersions cast (you think I didn’t notice “delicate flower,” Heather?), and lines drawn […]
