Further study into continuum mechanics is exciting and explains almost everything! Continuum mechanics is, without any doubt, the scientific discipline of the future. It is probably also the discipline that will bridge Newtonian physics with the field theory
(Ruđer Josip Bošković, Max Planck, Peter Higgs)
Continuum mechanics explains precisely what forces are available to humans to work with. Forces that can be used for energy conversion and all other kinds of applications.
