Sep 12, 2017 at 0:37 comment added Emilio Pisanty Your first bullet point makes the claim that the kinetic energy of a massive particle is bounded because its velocity is bounded; that is incorrect and little more than misinformation. (The rest of your claims are irrelevant to the question but they're not incorrect.) In uninterested in further discussion.
Sep 11, 2017 at 20:03 comment added HolgerFiedler @EmilioPisanty "a simplified description of fluid matter, temperature is proportional to the average kinetic energy of the random microscopic motions of the constituent microscopic particles, such as electrons, atoms, and molecules, but rigorous descriptions must include all quantum states of matter." From en.wikipedia.org/wiki/Temperature
Sep 11, 2017 at 19:09 comment added Emilio Pisanty No. Read my comments again.
Sep 11, 2017 at 18:24 comment added HolgerFiedler @EmilioPisanty So the temperature of a subatomic particles does not depends from its motion (in a gas in some closed volume as well as vibrational in a rigid body)?
Sep 11, 2017 at 16:50 comment added Emilio Pisanty Because relativistic kinetic energy is not a quadratic function of velocity. See any introductory textbook on special relativity, or indeed the relevant sections of Wikipedia, for further details - ideally before posting more misinformation on the site.
Sep 11, 2017 at 15:52 comment added HolgerFiedler @Emilio How this is possible?
Sep 11, 2017 at 13:25 comment added Emilio Pisanty Your first point is completely incorrect. A particle's energy can increase without bound even with its velocity bounded by $c$.
Sep 11, 2017 at 12:26 comment added Gabriele Citossi I belive it is geometrically realiable to focus more than 4Pi Stereorad of light from "one" source at a same temperature. In this case the temperature of the point will rise over the source temperature?
