The energy changes associated with physicochemical processes are the province of thermodynamics, a subdiscipline of physics.
Hawking's enthusiasm for a "theory of everything" highlights how he didn't share Einstein's breadth of vision in science, but focused almost exclusively on one subdiscipline of physics.
Cosmology as a subdiscipline of physics differs in some respects from mathematical, philosophical and classical observational cosmology, but of course the different approaches are in constant interaction.
Subdisciplines of physical chemistry include electrochemistry, photochemistry (see photochemical reaction), surface chemistry, and catalysis.
A rapidly developing subdiscipline of physical chemistry is surface chemistry.
Process sedimentology, a subdiscipline of physical sedimentology, is concerned with the detailed bed-by-bed description of siliciclastic sedimentary rocks for establishing the link between the deposit and the physics of the depositional process.
We attempt to quantify the evolution of ideas and subdisciplines within physics as they emerge, interact, merge, stagnate, and desist.
From high-energy particle physics to atomic, molecular and optical (AMO) physics to condensed matter physics, Hill's publications span a broad range of physics subdisciplines.
Robert Garisto, an assistant editor at Physical Review Letters, says that his publication's efforts are complicated by the increasing specialization of physics subdisciplines, but are nevertheless yielding "some success".
Schwartz marvels that Fermi, working when it was still possible to "master all of physics," did so "across all subdisciplines of the field — astrophysics, nuclear physics, particle physics, condensed matter physics, even geophysics".
"Son's contribution has been working across subdisciplines to use techniques and insights from one area of physics to learn things in other areas of physics," said Emil Martinec, professor of physics at the University of Chicago.
