... The most used approach to cosmology in string theory is to use adiabatic approximation. In such an approach, one uses a collection of fields {F(t)} to describe the background at any given time t, F(t) can be a scalar field, or the geometry parameter. By adiabaticity, we mean that the physics of {F( ...

CHAPTER 3: The Experimental Basis of Quantum Theory
... Classical theory predicts that the total amount of energy in a light wave increases as the light intensity increases. The maximum kinetic energy of the photoelectrons depends on the value of the light frequency f and not on the intensity. The existence of a threshold frequency is completely inexplic ...
