Physics is a diverse area of study and in order to make sense of it scientists have been forced to focus their attention on one or two smaller areas of the discipline. This allows them to become experts in that narrow field‚ without getting bogged down in the sheer volume of knowledge that exists regarding the natural world. Below is a list - by no comprehensive - of different disciplines of physics. The list will be updated with new additions and definitions as appropriate. Acoustics - the study

Topic 12 ATOMIC STRUCTURE: Electronic configuration 12. 1. Ionization energy If an electron obtains enough energy it jumps beyond the highest energy level and becomes a free electron: the atom itself becomes a positive ion. This electron transition is represented as follows: n = 1 to n = (. Notation n = ( refers to the “world” outside the atom – beyond the control of the nucleus; any electron outside an atom has no potential energy (energy = 0). With hydrogen the ionization energy can be

Pauli Exclusion Principle Wolfgang Ernst Pauli was an Austrian theoretical physicist famous for his work on the spin and quantum theory‚ and for the beneficial finding of the Pauli exclusion principle. Pauli was born on April 25th‚ 1900 and died on December 15th‚ 1958. He was a Foreign Member of the Royal Society of London and a member of the Swiss Physical Society‚ the American Physical Society and the American Association for the Advancement of Science. Pauli helped to set in place the basis

long-distance transmission of data over optical fibres; they also ensure narrow spot-size laser read/write beams in CD and DVD players. In quantum optical devices‚ microcavities can coax atoms or quantum dots to emit spontaneous photons in a desired direction or can provide an environment where dissipative mechanisms such as spontaneous emission are overcome so that quantum entanglement of radiation and matter is possible. Applications of these remarkable devices are as diverse as their geometrical and

Maurice Dirac (1902-1984)‚ known as P. A. M. Dirac‚ was the fifteenth Lucasian Professor of Mathematics at Cambridge. He shared the Nobel Prize for Physics in 1933 with Erwin Schrodinger.[2] He is considered to be the founder of quantum mechanics‚ providing the transition from quantum theory. The Cambridge Philosophical Society awarded him the Hopkins Medal in 1930. He was awarded the Royal Medal by the Royal Society of London in 1939 and the James Scott Prize from the Royal Society of Edinburgh. In 1952
