And don’t fall for the con man selling you the sham poo.
… and then get myself back together again.

After successful self-reassembly, the system stands up and continues its task
… which is apparently to fall over like a drunk
sailor soldier. (Sailors walk randomly, but don’t fall down. Everybody knows that.)
The test subject, a common house mouse, briskly traversed the complicated wooden maze in under 30 seconds or, according to the study’s final report, roughly 1/8,789,258 as long as it took the lab to secure funding for the experiment.
“Had we obtained any usable data, perhaps that information would have led to the development of a cure for neurodegenerative diseases like Alzheimer’s,” said Dr. William Eng, who led the team responsible for creating the maze. “What is unclear at this time is why this particular mouse had to be such a dick and render useless all the work we had put into this controlled behavioral experiment.”

We want to put a sundial up on the new building on which I’ve been working. (sooooo close to being done, too). I had joked at one point that we would mount a light that would move around the gnomon, so you could read it at night. Just like that first clock.
But, take any of these with a 5 MHz or even 1 pps input, and we could do something with it …
UPDATE: an animated version of the “word” clock
More than you probably wanted to know about ampersands and how they look in different fonts.
As both its function and form suggest, the ampersand is a written contraction of “et,” the Latin word for “and.” Its shape has evolved continuously since its introduction, and while some ampersands are still manifestly e-t ligatures, others merely hint at this origin, sometimes in very oblique ways.
… he’s my unbibium.
Reports of a naturally occurring superheavy element
Non peer-reviewed reports, mind you, this is on arXiv
In the neighborhood of Z = 122, A = 292, abundance = 10^-12, relative to thorium, and a half-life in excess of 100 million years. Found when doing mass-spectrometry on Thorium. The half-life appears to be inferred from the relative abundance. If it’s real.

Notice that the ears are cooler — an elephant uses its ears for thermoregulation. The same idea as fins on any heat sink: lots of surface area. That’s necessary because of the elephant’s shape (the spherical approximation is much more reasonable for an elephant than for a cow) meaning has a small surface-to-volume ratio, so it’s efficient at retaining heat.
With a wide surface area of outer ear tissue, hot blood in the arteries is cooled as it is filtered through the vast network of capillaries and veins. Thus, the body temperature is regulated with the cooled blood returning to the main body.
