Two further works, one on the mathematical theory of heat and the other on hydrodynamics , were in preparation at the time of his death.
Jeffrey's work was on the applications of mathematics, in particular he worked on hydrodynamics , viscous liquids and elasticity.
His interests in science itself were mainly in the area of mathematical physics, and in particular thermodynamics, hydrodynamics , elasticity, mathematical chemistry, and mechanics.
We could not understand chemistry and hydrodynamics .
His work on machines includes much in the area of applied mechanics, but he was also interested in applied hydrodynamics and steam engines.
Thus, the lipid dynamics depend on the friction and not on hydrodynamics .
He was interested in their applications to dynamics, hydrodynamics , elasticity, and electrostatics.
Current research focuses on the forces that act on a body moving through the water, the science of hydrodynamics .
He was also interested in hydrodynamics and hydraulics and he moved on from making sundials to invent other machinery, in particular pumps.
His early work was on magnetism and electricity but he soon concentrated on hydraulics and hydrodynamics .
