Paul Preuss

Beginning in the 1980s I wrote freelance science articles on topics like molecular engineering, the Carlos Casteneda controversy, how Star Wars achieved its special effects, Paolo Soleri’s architecture, and materials harder than diamond, for magazines like Discover, Science 80-86, and Human Behavior. For Walter Annenberg’s short-lived Panorama I previewed Carl Sagan’s Cosmos, and it led to my working with Carl, Ann Druyan, and Gentry Lee on a proposed TV series called Nucleus. (Alas, it did not fly.)  

From 1997 until 2013 I wrote for Lawrence Berkeley National Laboratory and got a thrilling education. I was there for the discovery of dark energy and wrote about it until Saul Perlmutter won the Nobel Prize (and after).  At the other extreme, I learned that duct tape really can do almost anything, except seal ducts. Unfortunately blogs and aggregators and even newspapers routinely republish press releases as if they’re news stories. They are not.

Recently I’ve discovered a whole new realm with direct impact on people’s lives: engineering. It ain’t what it used to be.

Here are some favorite stories.
