Hello, Joel. Always happy to hear from Canadians. The claims made in the paragraph you cited have some validity, but the paragraph is so poorly written, it must be parsed carefully. Picture this: In a hydrogen atom, an electron (there's your charged particle) is circling the proton nucleus. (There's the orbit) Particles in motion want to travel in a straight path, but to keep the electron in a circle it must be accelerated toward the nucleus. Accelerated charged particles radiate energy according to classical electrodynamics. That the hydrogen atom does not radiate energy is what gave Niels Bohr the idea that classical doesn't work at the atomic level. So he postulated that the electron can only orbit at distances from the nucleus that give the electron angular momentum equal to (n*h/2*pi) where h is Planck's constant (6.63E-34 joule-seconds), pi is 3.1415926, and n MUST BE A POSITIVE INTEGER GREATER THAN 0. So the electron has only particular allowed orbital distances from the nucleus. To make the long story short, this theory gave rise to Erwin Schrodinger's wave mechanics which is (sort of) what your paragraph is talking about. I recommend you view The Mechanical Universe, episode 50, called Particles and Waves for a much better explanation than I can give you here. As to the website you cite, (I visited it), I am suspicious. I don't know what "spin waves" are. Ask every science person you know if they can define spin waves. Ask Bob McDonald (on Canadian Broadcasting Corporation's Quirks and Quarks) if he can find a scientist to tell you what a spin wave is. I don't think they exist. Sometimes people write incomprehensible paragraphs to make themselves look impressive. Good scientists write clearly because they want to communicate ideas. Positive impressions that result are a byproduct. Larry Skarin Addendum. I have looked up spin waves from the website you stated. Spin waves do exist within crystal lattices. So I learned something. However, there is nothing I can see in spin waves that would lead to possible "antigravity" effects stated in Vasant's website. So I continue to be skeptical.
