Today I learned that Sir Isaac Newton actually dabbled in medicine and tried to create a remedy for the bubonic plague, namely the following recipe: 1. You take a live toad and hang it by its legs in a chimney for three days. 2. The toad, under extreme stress, eventually vomits up "earth with various insects in it" and dies. 3. You collect that vomit on a dish of yellow wax, grind the dead toad into a powder, and mix them together. 4. You form this into "lozenges" (essentially amulets) to be worn on the affected area to "draw out the poison." Given his vast intellect, this remedy surely must have worked as reliably as his laws of motion!
