TIL: Tungsten has 4 different isotopes that are considered stable, and naturally-occurring Tungsten is a mix containing significant amounts of all four (more than 10% of each).

Baking egg shells, as one does. For most of my life I added these to holes dug for tomatoes (because Mom), but I've since learned that that has no effect at all because the calcium carbonate doesn't really dissociate in real time unless you dose it with acids. Same reason I've stopped adding them to the compost. I'm going to grind them up and offer to local birds (I don't have chickens anymore). #CalciumCarbonate #eggs #eggshells #birds #calcium #calcite #chemistry #compost #tomatoes

Somehow reminds me of "attainable region theory" which is a branch of #chemistry that also has a homepage:
attainableregions.com/
After I learned about this I immediately registered
algebraicstatistics.org/
as the community page for the field of Algebraic Statistics.
But somehow, areas of math or science having their own homepages stayed a niche phenomenon.

Geology folks, is this a stain caused by iron-oxides? Shawangunk conglomerate near Mohonk Lake in New Paltz, New York. #NewYork #mohonk #geology #rocks #quartz #chemistry

My Grade 12 Chemistry teacher, in 1995, had us all do projects where we had to figure out and test different chemical mixtures to make a battery. He said he thought it would be the most important technology in future.
Boy were you right Dr. Peterson.
Too bad I sucked at math. 😂

I don't understand Navier Stokes, i only understand what it is used for, but i like the "AI soap" around it.... 😂
