Hundreds of other organizations exist in the various sub-fields of anthropology, sometimes divided up by nation or region, and many anthropologists work with collaborators in other disciplines, such as geology, physics, zoology, paleontology, anatomy, music theory, art history, sociology and so on, belonging to professional societies in those disciplines as well.

In particular, social sciences often develop statistical descriptions rather than the general laws derived in physics or chemistry, or they may explain individual cases through more general principles, as in many fields of psychology.

Professional astronomers are highly educated individuals who typically have a PhD in physics or astronomy and are employed by research institutions or universities .< ref >

In chemistry and physics, the atomic number ( also known as the proton number ) is the number of protons found in the nucleus of an atom and therefore identical to the charge number of the nucleus.

The conventional symbol Z comes from the German word meaning number / numeral / figure, which prior to the modern synthesis of ideas from chemistry and physics, merely denoted an element's numerical place in the periodic table.

The standard model of particle physics was developed that so far has successfully explained the properties of the nucleus in terms of these sub-atomic particles and the forces that govern their interactions.

In the Standard Model of physics, electrons are truly elementary particles with no internal structure.

The letter alpha represents various concepts in physics and chemistry, including alpha radiation, angular acceleration, alpha particles, alpha carbon and strength of electromagnetic interaction ( as Fine-structure constant ).

Another possibility, raised in an essay by the Swedish fantasy writer and editor Rickard Berghorn, is that the name Alhazred was influenced by references to two historical authors whose names were Latinized as Alhazen: Alhazen ben Josef, who translated Ptolemy into Arabic ; and Abu ' Ali al-Hasan ibn al-Haytham, who wrote about optics, mathematics and physics.

Frank Tipler has argued that physics can explain immortality, though such arguments are not falsifiable and thus do not qualify, in Karl Popper's views, as science.

According to Price, the dream world will not follow the laws of physics just as ordinary dreams do not.

Atomic physics is the field of physics that studies atoms as an isolated system of electrons and an atomic nucleus.

The term atomic physics is often associated with nuclear power and nuclear bombs, due to the synonymous use of atomic and nuclear in standard English.

However, physicists distinguish between atomic physics — which deals with the atom as a system consisting of a nucleus and electrons — and nuclear physics, which considers atomic nuclei alone.

As with many scientific fields, strict delineation can be highly contrived and atomic physics is often considered in the wider context of atomic, molecular, and optical physics.

Atomic physics always considers atoms in isolation.

It is not concerned with the formation of molecules ( although much of the physics is identical ), nor does it examine atoms in a solid state as condensed matter.

By this consideration atomic physics provides the underlying theory in plasma physics and atmospheric physics, even though both deal with very large numbers of atoms.

The majority of fields in physics can be divided between theoretical work and experimental work,
