A few weeks ago, I noted in this post that I’d had some difficulty with a new laptop computer, given by a long-time friend as a gift. I’ve been thinking about the outcome of the repair situation, and decided to use it to address a more-general issue. Since that post, I had two visits by an on-site technician. The gift …
“That’s Ridiculous!”
My reading is eclectic, and I never know when I get started what I’m going to find. A recent item got me thinking about technology and its uses—and potential “misuses”. (The reason for the quotation marks will become apparent in a few sentences.) First a bit of context: ‘Way back when I was an English major, I participated in a …
The Urge to Merge
I come across all kinds of interesting things in the course of my daily activities. Take this item from the Proceedings of the National Academy of Sciences, which describes how and why mosquitos aren’t just crushed when they collide with raindrops—which are many times more massive than the troublesome insect. Using high-speed videography, they demonstrated that mosquito’s strong exoskeleton and …
Dragons Exist!
Activities in space and on Earth today continued the opening of a new chapter in spaceflight. An uncrewed capsule, hight Dragon, containing a nominal mass of otherwise expendable and relatively unimportant cargo, docked with the International Space Station (ISS). This it the first time a commercial construct has docked with the ISS; previously, only capsules officially from governments have done …
Perceived Powerlessness?
The news in several places that the recently released movie, The Avengers broke the $1 billion mark for ticket sales (see here, for example) left me wondering, Why? What is it about this movie that has knocked earlier blockbusters (such as the Harry Potter canon) off their pedestals? I mean, I love a good movie, and may even set things …
Taking Big Bites
A couple of weeks ago there was much sound (and some fury) at the prospect of a group of billionaires coming together to form an entity that would seek out and mine asteroids. I loved it! That asteroids may be sources of multiple gigatons of useful materials (metals, mostly) has long been known. That mining them could bring untold riches …
Protective Coloration
A recent report from the California Academy of Sciences caught my eye, as it seemed to have implications for organizational dynamics. Summarized here, with a video of the interaction here, the report describes how a fish has developed the capability of imitating the look of an octopus that imitates the look of potentially dangerous fish, thereby allowing the octopus and …
What Would You Do If You Could Not Fail?
I came across this question recently via two different communications channels (Wired magazine and a YouTube video), both referring to the same person. That person is Regina Dugan, who—until March 2012—was director of the Defense Advanced Projects Research Agency, or DARPA. She left DARPA to move to Google, and faced lots of criticism for the way she allocated work to …
Human Spaceflight: In Harm’s Way
Because of my long association in various contractual capacities with NASA, friends and neighbors often turn to me to opine about happenings with the agency. The most recent spate of questions began with the stand-down of the Space Transportation System, aka the Shuttle. Most have the perception that NASA is folding. Completely. I hasten to reassure them that NASA is …
Functional Fixedness
What do a flock of starlings (known as a murmuration) and ferromagnetism have to do with each other? On the surface, probably nothing. Nothing, that is, unless you are a team of scientists with a perspective and approach that goes outside what their nominal area of study seems to call for. A team headed by William Bialek at Princeton University …
