Guest Post: The Three Quarks of Life

This is a tough post to read, tougher to look at.  Some background might help. In 1993 Chris Arnade got a PhD in physics and then went to work on Wall Street.  Starting in 2007, Chris started taking long walks with his camera through New York City, where he found a lot of ambiguity and unsolvable […]

Forward by Failure

A few years ago, I decided to take up hunting. This was kind of a big deal, because I’d spent the first decade-plus of my adult life as vegetarian. I became a big game hunter for the same reason I raise chickens — to know where my food comes from and ensure that it’s raised […]

Seeing Mammoths

Seeing a mammoth is not the same as looking over a zoo wall at a modern elephant, or even standing next to a live, gray, wrinkled wall of flesh with scant, coarse hairs. Watching the flexible, prehensile reach of an elephant’s trunk and the slow cross-wise chewing of hay, I’ve found it hard to see […]

Guest Post: Affair of the Heart: IV. Day of Reckoning

The Last Word

October 20-24, 2014 In his third post, Colin Norman faces a daunting prospect: heart surgery. “The operation isn’t as simple as snipping out the piece of aorta that includes the aneurysm and sewing in the Dacron tube. Because my aneurysm is right at the root of the aorta, the surgery would involve the left ventricle […]

Conversation with Sharon & Geoff: Starship Fusion

Last week, Lockheed announced it had a small team working on what it calls a Compact Fusion Reactor.  Fusion is the opposite of fission that’s used in nuclear plants today; it can produce enormous amounts of energy; the fuel for  itis cheap and plentiful; a small fusion engine would solve the world’s energy problems. I […]

On a Decade of Getting Pooped On By Birds

1. Washington, D.C., 2004 or so A bench around a circular planter, with a tree in it. I was eating my lunch. I felt something on my arm. We call it poop, but the stuff that comes out of birds’ behinds is more complicated than that. Birds, like most vertebrates that aren’t mammals, have a […]

Guest Post: Bobby Gborgar Joe Speaks From His Bones

October 14, 2014:  At a heady, expert-packed Ebola forum assembled at Johns Hopkins University, a Liberian man said more in a minute and half than everyone else said in five hours. He summed up the United States tainted history with Liberia and begged for respect, this time around. The expert forum was the best, yet. […]
