This list is full of nuggets and gems of potentially useful facts! One tidbit I really liked was the fact that monatomic silver ions has the metallic aftertaste, but polyatomic silver particulate has no taste. This reminded me so much of Sir Ronald Fisher's famous anecdote of the lady at a tea party who claimed she could taste the difference between milk added to tea, and tea added to milk. Everybody at the tea party jeered at her claim, except Sir Ronald. He invented the seminal exact 2x2 contingency table test just to test her hypothesis. Some historians of science say this episode at a tea party was the birth of modern exact, small- sample statistics!
