... vacuo, the polarizability is αi ≈ 4πε0ai3 = 3ε0vi. This is readily derivable for a simple oneelectron Bohr atom. However, if ε > εi, as might occur in a condensed medium (readily in water, where ε = 80), the polarizability is negative, implying that the direction of the induced dipole is opposite to ...

A great practical advantage of Fq'/Fm' is the fact that for the calculation of this parameter only Fm' and F' are needed to be determined, both parameters can be measured in the light, i.e. no dark-adapted leaf material is needed. However, due to the fact that Fq'/Fm' is strongly affected by the lig ...

History of quantum field theory

In particle physics, the history of quantum field theory starts with its creation by Paul Dirac, when he attempted to quantize the electromagnetic field in the late 1920s. Major advances in the theory were made in the 1950s, and led to the introduction of quantum electrodynamics (QED). QED was so successful and ""natural"" that efforts were made to use the same basic concepts for the other forces of nature. These efforts were successful in the application of gauge theory to the strong nuclear force and weak nuclear force, producing the modern standard model of particle physics. Efforts to describe gravity using the same techniques have, to date, failed. The study of quantum field theory is alive and flourishing, as are applications of this method to many physical problems. It remains one of the most vital areas of theoretical physics today, providing a common language to many branches of physics.
