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.
