| His early work was on magnetism and electricity but he soon concentrated on hydraulics and hydrodynamics. |
| A lowbred hodgepodge with the hydrodynamics of a potato, the makeshift vessel looked as if it would buckle on the first rapid. |
| His work on machines includes much in the area of applied mechanics, but he was also interested in applied hydrodynamics and steam engines. |
| The application of fish hydrodynamics to the silencing of propulsors is considered. |
| He was also interested in hydrodynamics and hydraulics and he moved on from making sundials to invent other machinery, in particular pumps. |
| In particular he applied his methods to equations resulting from electromagnetics, then later to those arising from hydrodynamics. |
