Education

Maker Education is such a valuable role. These stories will bring you the latest information and tales of maker educators who area spreading the maker mindset. Help others learn how to make things or how to think like a maker at makerspaces, schools, universities, and local communities. The importance of maker education can not be understated. We appreciate our educators.

The mechanical elegance of the pop-can stay tab

If you’ve been around long enough to have ever actually blown out your flip-flop, stepped on a pop top, you’ve already got one great reason to appreciate the 1975 introduction of the stay-on tab or stay tab: No more little metal razors littering the beaches.

Now, “Engineer Guy” Bill Hammack helps us appreciate the stay tab for another reason: It’s a little gem of mechanical poetry. There’s a lot going on when you pull that little ring. Bill’s video exegesis of that action, like all Bill’s videos, is a little piece of poetry unto itself. I can’t get enough of ’em. [Thanks, Bill!]

Stigler’s Law of Eponymy

A comment on this morning’s cometarium post reminded me of this famous axiom in the history of science: “No scientific discovery is named after its original discoverer.” Stigler’s Law is named for University of Chicago statistician Stephen Stigler, who attributes it to sociologist Robert K. Merton. [Thanks, Rahere!]

Top 10: Unusual scientific phenomena videos

As evidence, nothing beats one’s own senses: I’ll have to see that for myself. But some experiments are too expensive, too time-consuming, or too dangerous for most folks to reproduce on their own, and for these, well, the next best thing is video. And the tubes are rich with great footage of phenomena that have to be seen to be believed. Here’s a sampling of some of the gems we’ve covered, over the years, to get you started.

Jaw-dropping “unmixing” demo appears to reverse entropy

I identify as a scientist, but I gotta admit: When I saw this video from Steve Spangler Science, my first impulse was to jump back from the computer, cross myself, and douse the screen with holy water. It reminded me of a line from John Carpenter’s underappreciated 1987 horror movie, Prince of Darkness:

And we assume time is an arrow because it is as a clock…Cause precedes effect – fruit rots, water flows downstream. We’re born, we age, we die. The reverse NEVER happens…

Unless, apparently, you’re dealing with a system operating under conditions of laminar flow. Obviously, there is no real “violation” of the second law of thermodynamics, here, but because almost all of our intuitions about how liquids are going to behave are formed under conditions of turbulent flow, it sure does seem like it.
