I came across this interesting item last week, which describes how a person’s world view was changed by way of technology. It got me thinking about how wedded many of us are to doing things the way we have always done them, or how others have always done them, or, in some cases, not doing something at all because to …
Sci-fi? No; reality!
This video/animation of the launch-through-landing of the Mars Science Laboratory (MSL), aka Curiosity, was initially produced in 2011, long before the successful landing of Curiosity on Mars. Except for the juvenile need to include sounds where no sound could carry (i.e., outside the two planets’ atmosphers), this is exceedingly well done, and worth about five minutes of your time. The …
Can’t Do A Thing About It
Living as I do within 100 miles or so of Yellowstone National Park, its geological instability is very present to me. Loosely speaking, the volcano upon which Yellowstone sits erupts—on average—every 640,000 years. The last such megaexplosion was…just about 640,000 years ago. Statistically, we can expect another such megaexplosion any time now. Geologically speaking, “any time now” covers a lot …
Crossing Boundaries
Have you ever been in a situation where—despite all your best efforts—some circumstance completely beyond your control crept into your carefully constructed reality, changing things for the worse, or even just forcing you to take some action that hadn’t anticipated? I got to thinking about this as a general phenomenon this morning upon seeing this item that shows that half …
Do I Really Need It?
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 …
Expectations
Although the guidelines have been available to a subset of interested parties since 2011, it was not until late May 2012 that the broader community became aware of and accepted “…guidelines established by NASA to protect lunar historic sites and preserve ongoing and future science on the moon.” Designed to maintain the historical and scientific integrity of these historical sites—such …
Go With the Flow
A recent report addresses what appears to be a long-observed phenomenon in some circles: That bubbles in stout often sink, rather than rise. No, this is not an effect enhanced by increased consumption of the imbibable under discussion; rather, it is a very real phenomenon, seen even by those who are not inclined to see what is not there. It …
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 …
