Calcium oxide (found in seashells) will glow with a blindingly bright light when heated with a high temperature torch in a process known as candoluminescence, used for limelights in theathers in the 19th century [📹 Phil Cook:

I was this old when I learned the origin of the word “limelight.”

So that’s where the expression being ”in the limelight” came from. I love this account!

I saw that Doritos are pretty flammable. Great tinder. I keep that in mind, for no particular reason. Maybe the occasional apocalypse or two, but that's about it...

Asteroid Hyalosis (also known as hyalosis asteroidea) is a recognized medical condition where the vitreous humor (the gel in the center of the eye) contains tiny, bright calcium–lipid deposits that resemble a “starry sky” when viewed under light.

By as early as the mid-19th century, America was the world’s leader in education. But in the early 20th century, we made a huge mistake ... and we’re still living with the consequences.

It has Quantum Properties?! Egyptian blue (calcium copper tetrasilicate, CaCuSi₂O₆) is the world's oldest known articial pigment. What makes this anomalous is not the pigment itself but its recently discovered quantum-optical properties. It emits near-infrared light with an exceptionally high luminescence quantum yield of 10.5%, making it a promising candidate for biomedical imaging, telecommunications, and laser applications. Even when reduced to nano-sheets a thousand times thinner than a human hair, this luminescent quality is fully retained. The pigment also has a chemistry similar to high-temperature superconductors. Washington State University researchers recreated the pigment in 2025 and found that "with just small differences in the process, you got very different results" This suggests that the ancient Egyptians had refined and controlled production processes whose knowledge was lost by the Renaissance. This clip is from my documentaion of the Saqqara Pyramid Complex in Egypt with Geoffrey Drumm from The Land of Chem presenting his theories, which align with these quantum property findings.

“To get your thyroid activity up, it requires good nutrition, high ratio of calcium to phosphate, if possible, a one-to-one ratio is very good, but many people on a standard diet are getting five times as much phosphate as calcium.” “Keeping a very, very high ratio of calcium to phosphate in your diet is helpful, because that helps to suppress the parathyroid hormone. And the parathyroid hormone blocks the use of oxygen in all of your tissues, and that leads to the production.” “If you have a high ratio of calcium to phosphate, calcium happens to suppress the fermentation of fiber and starch in the intestine. So high calcium intake will actually reduce the production of the endotoxin as well as reducing the consequences of your reaction to the endotoxin.” Ray Peat
