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 […]

Quasiparticles

Elementary particles are not so much discrete “balls” of matter like marbles or planets as they are “clouds” of localized characteristics. Particles are often “fuzzy” around the edges, in terms of describing their physical limits and their location in space. But we know that these clouds or lumps that we call particles can interact with […]

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 […]

CERN Detects a Pentaquark

Quarks are the pieces that combine to make protons and neutrons and other composite components known as hadrons. There are two main “families” of hadrons, categorized by how the quarks combine. Baryons, such as protons and neutrons, are composed of three quarks. Mesons are composed of a quark and an anti-quark, and are involved in […]

Simplifying Quantum Mechanics Is Possible

Ignoring the script that insists, “the quantum world and the large scale world play by two different sets of rules”, this simple demonstration shows that there may be an equally simple explanation for “quantum” events and the “wave-particle duality” paradox. All of our observational data seems to confirm that elementary “items” at some level act […]

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 […]
