Physics emerged as a separate science only in the early 19th century; until that time a physicist was often ... a mathematician, philosopher, chemist, biologist, engineer, or even primarily a political leader or artist. Today the field has grown to such an extent that with few exceptions modern physicists have to limit their attention to one or two branches of the science. Once the fundamental aspects of a new field are discovered and understood, they become the domain of engineers and other applied scientists. The 19th-century discoveries in electricity and magnetism, for example, are now the province of electrical and communication engineers; the properties of matter discovered at the beginning of the 20th century have been applied in electronics; and the discoveries of nuclear physics, most of them not yet 40 years old, have passed into the hands of nuclear engineers for applications to peaceful or military uses.

The UK Department of Physics and Astronomy comprises 28 regular and 5 active adjunct and/or emeritus faculty members, 8 post-doctoral researchers, 16 office and technical staff members, 64 graduate and 57 undergraduate students. Among its faculty are 10 Fellows of the American Physical Society and several award winning educators. Undergraduate majors and graduate students take a complete array of courses with small class sizes spanning modern topics in physics and astronomy, and they work closely with faculty researchers in studies of nuclear and particle physics, condensed matter and atomic physics, and astronomy and cosmology.

Theoretical physics attempts to describe and predict the fundamental laws governing the structure and interactions of matter. The Duke group focuses on the rules governing the interactions of quarks and nuclei (QCD or quantum chromodynamics) using a variety of theoretical and computational techniques. The group focuses both on trying to predict the structure of matter by deriving quark interactions from first principles and by investigating the behavior of quark matter under the most extreme conditions. These two approaches give insight both into nuclear structure today and conditions in the early universe. See all Theoretical Nuclear and Particle Physics information.

The most basic parts of physics are mechanics and field theory. Mechanics is concerned with the motion of particles or bodies under the action of given forces. The physics of fields is concerned with the origin, nature, and properties of gravitational, electromagnetic, nuclear, and other force fields. Taken together, mechanics and field theory constitute the most fundamental approach to an understanding of natural phenomena which science offers. The ultimate aim is to understand all natural phenomena in these terms. See ... Classical field theory; Mechanics; Quantum field theory.

The culture of physics research differs from most sciences in the separation of theory and experiment. Since the twentieth century, most individual physicists have specialized in either theoretical physics or experimental physics. The great Italian physicist Enrico Fermi (1901–1954), who made fundamental contributions to both theory and experimentation in nuclear physics, was a notable exception. In contrast, almost all the successful theorists in biology and chemistry (e.g. American quantum chemist and biochemist Linus Pauling) have ... been experimentalists, although this is changing as of late.
