What is an orbit, anyway? And what do we mean by freefall, microgravity, and weightlessness? To answer these questions, first understand the difference between mass and weight. Mass is a property of all (ordinary) matter, and can loosely be thought of as the amount of stuff in that matter. A bucket full of iron nails…
When I won Writers of the Future last year, I burned off some of the anticipatory energy leading up to the workshop by interviewing my fellow winners. It was so much fun, I decided to do it again. This week, meet a name already familiar to some of you, Martin L Shoemaker. Stuart: Howdy Martin,…
David Gerrold wrote The Trouble With Tribbles, and has been writing ever since. He’s a curmugeon. And he’ss been around. Here is his list of “Essential Science Fiction/Fantasy Books from the Golden Age”. That is all Starship Troopers, Heinlein (runner-up, The Moon Is A Harsh Mistress, Heinlein) Why?

Recently, a writer friend asked how I define success as a writer. After all, anyone can write, and these days, anyone with a credit card can publish. But not every putative writer can get others to pay for her work. And let us be clear: the numbers here are crushing. Most literary agents consider only…
Check out this very cool article about how laser 3D scanning and 3D printing are being used to fully understand, resurrect, and improve upon the giant engines that carried us to the moon. Cool factoid: The fuel pump for the F1 engine consumed 55,000 shaft HP, more than the main propulsion system for a modern…

You know who had faith? Hiroo Onodo. He was the last officer to serve the old Japanese Imperial Army after World War II. He held out on a remote island in the Philippines for twenty-nine years until 1974, when he was found by a college dropout searching the world for ghosts. Even then, he held…
The first ape to leave his planet of origin and go for a walk on another is remembered today as a “great man”. Perhaps, and the honor is certainly well deserved, but if Maj. General Armstrong was great, it was more for his conduct on the ground than for his exploits in space. Humanity’s considerable…
It is a peculiar form of arrogance that leads from “I don’t know” to “those who claim to know are liars, conspirators, and scoundrels.” I once knew a fellow who believed that the transistor was (and could only be) the product of alien intervention. It’s unclear why he found this explanation more reasonable than simple…
