Let’s start with the wreckage of Blackbeard’s ship, Queen Anne’s Revenge. Seems there were a number of interesting medical devices on board.
In the century after that ship sank, submarine warfare was born. Alas, the first “successful” sub, the Hunley, sank. Now researchers are finally able to learn more about what happened to the Hunley.
And on a lighter note, Wikipedia has a fascinating article about Ship’s Cats. It discusses ship’s cats both real and fictional, up to and including Cat from Red Dwarf. Fairly early in the discussion, it states “Cats are able to detect slight changes in the weather, as a result of their very sensitive inner ears, which also allow them to land upright when falling. Low atmospheric pressure, a common precursor of stormy weather, often makes cats nervous and restless.” Yesterday morning around 5:30 AM, I observed this phenomenon personally. Purrsonally?
