Science Metaphors (cont.): Standard Candle

Nothing is entirely trustworthy.  Friends are inconstant; presidents and professors are making it up; your grandmother didn’t always know what she was talking about; your very senses can fool you; and one of these fine days even the sun will blow up. Where is the touchstone, the standard, the fundamental reference frame? Where is the […]

Rogue Planets

The latest alien planets hit the news like fireworks, I write about them a lot, and I’ve always found them boring.  I’d been convinced early on by an eminent astronomer who said flatly that finding extra-solar planets wasn’t, as he said, interesting.   In the first place, observations were nearly impossible and decades of claims turned […]

This Is Not About Climate Change

I read a nice essay saying that scientists make their advice to politicians too simple.  What scientists over-simplify, said the essay’s author, is their uncertainties.  I thought the author might be right: surely politicians don’t believe flat statements like, say, “climate change is making the world warmer and we’re all going to die.”  Not that […]

Freeman Dyson: It’s Complicated

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 […]

Eulogy for Jim’s Camera

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 […]

Science Metaphors (cont.): Mantle Drag

The older I get, the more people I know who have lost what they could not afford to lose.  I’ll repeat:  lost means gone, unrecoverable, not coming back; and what these people lost, they still need and want.  The problem is nearly universal and has no obvious solution, or rather, the solution is idiosyncratic and […]

We’re sorry, but Thomas Hayden, the New Person of LWON, will be unable to post today as promised.  Instead we present for your delight and edification, Heather.  Tom will be back as soon as possible and in the meantime, we send him our best wishes for recovery. Credit: Jehan Georges Vibert

New Person of LWON

Please meet Thomas Hayden, a new Person of LWON.  And let’s get this out of the way early:  he is not and never has been married to any movie star whatever.   He writes about ecology, energy, environment, and evolution and though he’s entirely a peaceable, friendly fellow, he writes a lot about war.  And sex.   […]
