How far is it around the earth?

How far is it around the earth? More specifically, if I was to set off from here in Wokingham following a great circle route, how far would I have to travel before I found myself back here in Wokingham? Well, if you look it up on Google the circumference of the earth is near enough […]

The Rydberg Constant and Rydberg Series

Here I take a look at the Rydberg formula in more detail and derive the Rydberg series, which is useful in calculating the change in energy level between any two states of the hydrogen atom and can be used to generate all of the other series:  Lyman, Balmer, Paschen, Brackett, Pfund, Humphreys etc.  I go […]

Louis de Broglie

Louis de Broglie

Prince Louis Victor Pierre Raymond de Broglie was born in Dieppe on August 15th 1892.  De Broglie first studied history, but developed an interest in physics as a result of working with his older brother Maurice.  Maurice had been a naval officer where he worked on early radio systems for ship to ship and ship […]

The Schrödinger Wave Equation

Following Bohr’s model for the hydrogen atom Louis de Broglie suggested that the electron could be considered as a wave rather than a particle and proposed that the wavelength of such a wave was Planck’s constant divided by the linear momentum of the orbiting electron.   In effect he was restating Bohr’s adopted assumption that angular […]

Otto Stern and Walther Gerlach

The Stern-Gerlach Experiment

This experiment is often cited as demonstrating that angular momentum is quantised.  In fact it does nothing of the sort, and indeed it clearly demonstrates that it is not, at least not in the way that physicists would have you believe. The Stern Gerlach experiment was first carried out by German physicists Otto Stern(1888-1969) and […]

The Quantum Catechism

Over recent years much has been said about the similarities between religion and science.  Religion and science, and especially physics, it are said are on a convergent path.  The religious establishment is particularly fond of this idea, especially when spoken by a scientist, since it enhances their credibility, bolsters their position of authority and helps recruit […]

The GUTs of the Matter

Scientists have long sought to show that various different forces of nature are in fact just different manifestations of a single common force.  It is felt that by doing so it will offer insights into the way the universe works and produce a much simpler model. The pressure to simplify our understanding of the universe […]
