QUANTUM STUFF – Quantum Mechanics

STRUCTURE OF THE ATOM A simple map of the atom: Particles – in the early days of atomic theory, all components were thought of as particles and this model is still taught at elementary levels. Nucleus – is a combination of larger particles found together at the center of an atom. The particles are the […]

Ballistic Electron Flow

Ballistic conduction is when electrons move through a medium with minimal scattering and resistance. This happens in nanowires and nanotubes because of their small diameter. Experiments confirm theory of “superballistic” electron flow – [mit.edu] The idea behind superballistic flow is that interactions among electrons make them move in a highly coordinated manner, mimicking the behavior […]

1930 – Cooper – bio

Leon Cooper was born in 1930 in New York, USA. He is most known for discovering how electrons pair together, creating a state of less resistance, known as superconductivity. These are now called, “Cooper pairs”. Bardeen, Cooper, and Schrieffer, built on this concept to create a theory of superconductivity in 1957. The three of them […]

Our Knowledge of Matter and Energy

We like to think that we know what “elementary particles” are made of, but in fact, while we may know some things about their behavior or interaction with other particles, we know little about their fundamental nature. Here are some of the things we know: Sometimes they act like waves and sometimes they act like […]

Vortex – Physics – Dimensions

First, watch this fascinating video about a half vortex demonstrated in a pool of water. Then, ponder the parallels in the world of energy and particle physics. Imagine the ends of the vortex as elementary particles connected by a hidden vortex tunnel in another dimension. wave particle duality electron spin EPR paradox Crazy pool vortex […]

1925 – electron “spin”

The electron acts more like a rotating cloud of electromagnetic charge than like a particle. The rotation or angular momentum of the field is called “electron spin”. The credit for discovering electron spin has been given by history to Samuel Goudsmit and George Uhlenbeck in 1925. Ralph Kronig proposed the idea earlier in the year, […]

1905 – photoelectric effect

Maxwell‘s equations showed that light, electricity and magnetism all had similar wave characteristics and suggested that light was a variation of the electro-magnetic wave form. If this was true, light and other electro-magnetic waves impacting metal would cause a flow of electric current in the metal. At the time, scientists were using electrified glass tubes […]

1887 – Schrodinger – bio

Erwin Schrodinger was born in Vienna, Austria in 1887 and was a physicist who made major contributions to quantum mechanics. The Schrodinger wave equation describes the state of an atom, including the electrons as mathematical waves. It was later demonstrated that Heisenberg’s matrix mechanics and the wave function were describing the same thing. PRECURSOR: 1777 […]
