Too often, I find myself in situation where I argue something that I know to be the case, only to find out afterward—in the face of incontrovertible evidence— that the opposite was true. How did I ever end up thinking one way, and finding out that what I had reported—and, worse, acted upon—was contrary to fact? A recent item may …
More Signal, Less Noise
News this week included a report that planet-searchers have found a “super-Earth” orbiting a star just 42 light years from “regular “(but still impressive) Earth. [Given that distance, Bob Murphy, a colleague and friend, has suggested that we name the planet “Douglas Adams”, author of Hitchhiker’s Guide to the Galaxy, in which that number has keen significance as the “Answer …
Overdesigning
SpaceX has done it again, albeit with a bit of difficulty. They launched a Falcon 9 rocket with a Dragon module to resupply the International Space Station (ISS). The launch itself was perfect off the pad, but just about 90 seconds into the flight, one of the vehicle’s nine engines malfunctioned. The Dragon docked successfully with the ISS today, but …

The caveat was usually along the lines of, “I think I remember”, or “I’m not sure if I remember this or just think I remember this.” Call it the onset of entropic consciousness, or just aging, but there it …
Levying Blame
I was the lucky recipient of a gift laptop last week, sent quite out of the blue by an old (as in long-term) friend. What generosity! I got right to work, checking it out, making sure the delivery manifest matched the options he had purchased for me, learning Windows 7 (I still mostly dwell in the XP realm; hey! It …
Unintended Consequences
It seems that The Machines are much in the news lately. I’ve seen several articles on increasing uses for drones and other UAVs in domestic “security” applications, not to mention the prospects of arming them for bona fide warfare. On a much less violent front, we have this item from the Wall Street Journal, which describes how a seemingly innocuous …
Leadership and the End of the Shuttle Era
The era of the Space Shuttle is over. Atlantis landed today, after a perfect trip to the International Space Station (ISS). Note that I referred to this voyage as a trip, despite NASA’s insistence on referring to such things as “missions”, or “expeditions”. I mean no disrespect–to the contrary! I’ve been a space cadet since before NASA existed. I cut …
