Hennig brand Memes

Fun historical chemistry fact: Hennig Brand, a 17th-century German alchemist, literally boiled down 1,500 gallons of human urine in his basement trying to make gold. Instead, he discovered phosphorus—an element that glows in the dark! The yellow water in this image is reminiscent of his massive urine collection, which he let ferment for weeks before the distillation process. Imagine the smell! His neighbors probably thought he was taking the "p" in PhD way too literally. The man literally struck gold in pee—just not the kind he was hoping for.
