The Bohr Atom
... in the case of the hydrogen atom, as the electron loses energy, it moves into an orbit of smaller radius, loses energy more rapidly and spirals into the nucleus within about 10−10 seconds. This cannot be correct since atoms certainly exist. This problem was solved by Bohr in an remarkable leap of th ...

The Kinetic Theory of Gases (2)
... exerted by our model gas. This calculation will demonstrate how to tackle calculations of this type in kinetic theory. We consider the behaviour of a small number of typical particles and use Newton’s laws of mechanics to calculate their behaviour. We then average over all the particles using the di ...

Creation and Annihilation Operators
... ◦ Obviously, HFS can contain linear combinations of states with different numbers of particles. While this may at first seem strange, it is no more “unnatural” than harmonic oscillator states, such as coherent states, that do not contain a definite number of phonons. Allowing the number of particles ...

Particle Physics Notes
... He plotted the spin ½ baryons and spin 0 mesons in so-called octets. There is a similarity between Mendeleev’s periodic table of elements and the super multiples of particles of Gell Mann. Both pointed out a deeper structure of matter. The strangeness QN is plotted vertically and decreases from 0 t ...

Geiger–Marsden experiment
The Geiger–Marsden experiment(s) (also called the Rutherford gold foil experiment) were a landmark series of experiments by which scientists discovered that every atom contains a nucleus where its positive charge and most of its mass are concentrated. They deduced this by measuring how an alpha particle beam is scattered when it strikes a thin metal foil. The experiments were performed between 1908 and 1913 by Hans Geiger and Ernest Marsden under the direction of Ernest Rutherford at the Physical Laboratories of the University of Manchester.
