I am trying to get my hands on an English or German translation of the seminal work by Gauss on fluid shapes in equilibrium: "Principia generalia Theoriae Figurae Fluidorum in statu Aequilibrii [General principles of the theory of fluid shapes in a state of equilibrium]" from 1830.
I have found a Latin version at hathitrust, but my Latin is virtually non-existent so that won't help me much.
Does someone know where I can find a German (Gauss was German after all) or English translation of this text? Or more in general, where I can find translations of scientific papers that where originally in Latin?
I have tried Project Gutenberg, which seemed like a good place to start, but the specific paper I'm looking for is not there. Are there any other websites/projects that have similar databases that I might try?
