Question: What is the relationship between the sum of the angles of a non-euclidean triangle being greater or less than 180 degrees and the definite breaking of the parallel postulate? Is the proof of this trivial? Edit: Additionally, can we say that if the angles of a triangle sum to greater...

Crossed with today I learned, but the path integral is the thought and mind of Norbert Weiner, originally. Fully worked out by Dr. Feynman. Edit: Norbert Weiner wrote the book "Ex-Prodigy: My Youth and Childhood". Some of the editions (maybe all) are nice collectibles.

A small thing, but I learned that Schroedinger's equation is a diffusion equation and path integral formulation is actually the thought of Norbert Weiner, originally.

Question: The idea of a continuum breaks down for a singularity when a geodesic become incomplete (the breaking of the idea that there was a continuous succession, where no part could be distinguished from neighboring parts, except by arbitrary division), and so with that does this indicate a...

Question: When thinking of continuums the most notable seems to be space-time but they also mark a simplification to reality like in continuum mechanics, often taught when learning the tensor calculus needed for general relativity. The question is that for general relativity when a geodesic...

Question: Is it meaningful to think of the repulsion of mutual color charge and the attraction of three different color charge in QCD as being indicative of the classical concept of work taking place? Exactly, how is this explained in the context of three charges needed to elicit the...

Electric charge is all I can see (thinking back to Griffith's book).

Question: Can we ultimately atttribute no work or net zero work done by a magnetic force to the closed magnetic field lines that results in Divergence zero of a magnetic field? That is, is it a misconception to say that closed magnetic field lines imply magnetic force will always result in no...

Question: Does the magnetic properties of an element, like Praseodymium, vary with radioactivity? That is, in general, does radioactivity (perhaps beta decay or alpha decay) subtly or otherwise alter the electronic structure enough to alter magnetic properties? The case for beta decay may be...

Music Playing: "Jive Talking", "Night Fever", followed by "Tragedy" by the Bee Gees. On Bee Gees Greatest. *Gets down off disco ball* We all do it. We all groove to it. Now admit to it! What do you shamelessly listen to?

By specialized I meant specialty, as in being indicative of further or some study.

Central heating: 350 B.C. Given Greek proclivity to the creation of large spaces this is mind boggling.

Mongolian throat singing is EXACTLY what's needed, along with singing bowls.Thank you. If not widely known, might I suggest the "Rough Guide to Music" series found on Amazon. Music Playing: An Open Letter to NYC, Beastie Boys, circa 2004 - decidedly not esoteric.

What is the most esoteric (especially in the sense of specialized) music you own and recommend? To suggest one: Turkwaz's "Nazar". A set of Sufi devotional love songs. Assembled, studied and performed by doctors of music.

Also, for anyone both interested and adventurous is the jazz of Cecil Taylor. I suggest starting with the 1968 "Unit Structures" or his later Unit's "Winged Serpent". Cacophonous but structured. These recordings are chaotic: unpredictable yet deterministic.
