A degree in physics is an excellent training for employment in high technology industries (e.g. communications, electronics, optics and photonics, semiconductors, medical devices) and also in fields such as second- and third-level education, meteorology, the environmental and medical sciences, and software design. A physics degree can also lead to an exciting career in fundamental research in any area of physics or in multidisciplinary areas such as nanotechnology, medical physics, biophysics, occupational health, and materials science. Theoretical physicists often work in the financial and actuarial sectors.
