Science folks...is there an explanation for this? I usually teach radiometric dating to 8th graders with an experiment where we record the temperature of hot water as it cools over time. The trend is roughly exp decay, but this year I tried to make the curve fit better. Why a fractional exponent?
A desmos graph shows the temperature above room temp of water cooling down over 45 minutes. An exponential regression fits moderately well, but a more complex function fits better. The exponent is raised to the two-thirds power.

As someone in a STEM discipline, I really abhor the kind of messaging that Mark describes. The messengers aren’t people who actually care about STEM. It’s really a shorthand for “do something practical, focus on your relation to the labor market”.

I'm giving a practice quiz in algebra 2 today, and it's 3 pages, so I figured I could put the answer key (shrunk to fit on one page) on the back. But with 3 pages, there's still an empty quarter page left. So, I made it appear recursively. Lol #ITeachMath

As the screenshot shows, I have officially reached half of the life expectancy for my demographic. All in all, I would say being alive has been acceptable I know no one is promised tomorrow, but even if my life was halfway through, at least I got to have a really cute dog youtu.be/Tj2v6k6NqOc

Preparing my lesson plans for this week, I came across upon one of my favorite slides I've ever made #EduSky #ITeachPhysics
This slide, titled "x and t are relative," is an explanation of simple relativity of measurement for location, time, and velocity. It features an image of a crowd of 12-inch rulers saying "all hail the one true ruler" in adoration of a 12-inch ruler on a throne wearing a crown. The text reads:

"Measurements of space and time are relative, or observer-dependent, because the universe doesn’t have built-in rulers or clocks.
We have to bring our own rulers and clocks, and there’s no reason mine is “correct” and yours is “wrong.” There is no experiment we can do to prove which frame of reference is the right one.
Therefore, we must abandon the idea that there is such a thing as a correct one."

I'm revamping my materials for the quadratics unit, including my tutorial on completing the square. I've always struggled with how to explain it without making it confusing, and I think this visual will help nicely.

My first reaction to this question is that it's an obvious AI mistake, that frequency and wavelength are two sides of the same coin But I suppose that if the listener is moving relative to the source, a perceived frequency will no longer be associated with its typical wavelength #ITeachPhysics
A YouTube learning poll that asks "in music, what characteristics of sound waves determine the perceived highness or lowness of a sound?" The choices are wavelength or frequency

America is the place that gave us Stevie Wonder, Conan O'Brien, the Hubble telescope, and Star Trek. It has tyrannosaurus rex fossils, the Appalachian mountains, Mammoth Cave, and the Grand canyon. If I was an alien anthropologist or xenogeologist, I would still at least appreciate America.
