The lowest hierarchy of IPC, subgroup, precisely defines a field of subject matter considered to be useful for "searching" purposes.
All those fields of matter, with their eensy-weensy quantum fluctuations, live in spacetime -- as far as we can tell, a spacetime governed by Einstein's general relativity.
It now appeared to him that the classical field theory of matter is not the key to reality.
Thus, from the point of view of the classical field theory of matter not two but three entities would have to be unified.
Weyl (1921b) remarks that he adopted the standpoint of the classical pure field theory of matter in the first three editions of Weyl (1923b) because of its beauty and unity, but then gave it up.
That's because as the Earth moves around the Sun, it is moving into a stationary field of dark matter - and for half the year it will be moving against the tide of dark matter - just like driving into the rain.
Cates is an expert on the theory of soft matter, such as polymers, colloids, gels, liquid crystals, and granular material, as well as the burgeoning field of "active matter".
He will be hugely missed as a towering figure in the field of soft matter.
The study of these systems, which are often complex and heterogeneous, grew out of the more traditional field of condensed matter physics.
At Karlsruhe, the extra money will help finance the university's highly regarded research in nanotechnology, the field of manipulating matter in dimensions as small as atoms or single molecules.
