Search For The Old Ones
One of the great revolutions in human thought was the concept of "Deep Time" — the notion that the Earth and the Universe are vastly older than recorded human history, and even the origins of the human species lie long before the invention of writing. Charles Lyell, the Victorian geologist, was probably the first person…

Still Bunk After All These Years
So here's an article from Quillette about "social constructionism" — in particular how postmodernists have applied the concept to the sciences, and how bad an idea it is. I was amused to see that one of the examples cited in the piece is Bruno Latour and Steve Woolgar's book Laboratory Life, because that book was…

We Apologize For The Interruption
Apologies for my absence. I was traveling and didn't have the time (or reliable Internet access) for 'blog posts. But because I was traveling on my own, I wound up having a lot of time to think about various things, and one of them was this 'blog. Up to now I have focused on "long…

The Magic Wand
There's a custom among science fiction writers that a story — a "hard SF" story, anyway — should only contain one element of "magic." By magic we mean some effect which is impossible under our current understanding of the universe. Or, if you're really strict, some effect which would be impossible to create with any…

An Age of Wonders?
I grew up in the post-Apollo era of space exploration. Skylab launched when I was in elementary school, and the Shuttle made its debut when I was a freshman in high school. What this all means, among other things, is that I have spent most of my life hearing ambitious plans for space exploration which…

Tennessee Valley Interstellar Workshop, Day 3

The participants were Dr. Paul McConnaughey of the Marshall Space Flight Center in Huntsville, Representative John Culberson of Texas, Representative Mo Brooks of Alabama (who represents Huntsville in Congress), and Lieutenant-General Steven…

Tennessee Valley Interstellar Workshop, Day 2
The first day of the Interstellar Workshop featured the Starship Century and Breakthrough StarShot groups. On Thursday the Tau Zero Foundation took center stage. The Tau Zero group aren't as wedded to a single goal or mission profile. Instead they've put a lot of effort into identifying key technologies which will benefit any interstellar exploration, and…

Tennessee Valley Interstellar Workshop, Day 1
Why "Tennessee Valley" for a conference in Alabama? Look at a map. The mighty Tennessee River meanders into northern Alabama on its way west. What with Knoxville, Huntsville, and Oak Ridge, the upper Tennessee River valley is quite the high-tech corridor. Just the place to plan how to send a probe to Alpha Centauri some…

Kitchen Report: Sous Vide
I know, I know: I'm about ten years late to the party on this one. Sous vide cooking techniques have become universal in the restaurant business, and probably half of the "foodies" in North America have a sous vide gadget sitting in a kitchen drawer somewhere. I'm a late adopter: I prefer to let other…

What I Saw At The Eclipse, Part 3
Finally, the whole reason for our trip to Charleston arrived: the great eclipse of 2017! And it was . . . cloudy that morning. The forecast called for overcast skies and a chance of thunderstorms. Uh-oh. We had picked our rental cottage precisely because it was in the path of totality, so we didn't have…
