• I wonder why - Johannes - 4/17/2008 8:33:33 PM
  • "Hot" in this context relates to particle velocities, not "temperature" as such. (n/t) - TB - 4/18/2008 12:41:04 AM
    • Hot IS particle velocity in this context. - et - 4/18/2008 5:50:17 PM
      • So, if you create a total vacuum, what's the temperature inside it? (n/t) - RobVG - 4/19/2008 1:08:41 AM
        • Temperature measures the thermal energy in a volume. - et - 4/19/2008 8:13:45 PM
        • That's like asking what the pressure is. - TB - 4/19/2008 2:03:36 AM
        • re: Would your total vacuum exclude photons? - Johannes - 4/19/2008 1:46:08 AM
          • Found will looking for something else. - RobVG - 4/22/2008 6:14:16 PM
            • "while" -(shees, sometimes forget to look at what I typed) (n/t) - RobVg - 4/22/2008 10:47:28 PM

          • Do photons have Temperature? - nick hoffman - 4/20/2008 9:30:17 AM
          • Google photon gas. (n/t) - et - 4/19/2008 8:11:34 PM
          • Do photons have mass? (n/t) - RobVG - 4/19/2008 2:01:05 AM
            • Johannes, this is a SCIENCE board, NOT religion - Moderator Nick - 4/20/2008 9:35:35 AM
              • re: Sorry about the conflict, but…….. - Johannes - 4/21/2008 2:09:42 AM
            • Not in the conventional sense. (n/t) - et - 4/19/2008 8:10:01 PM
              • Radiometers and solar sails don't work if light has no mass to plug into the momentum equation. (n/t) - alcaray - 4/19/2008 8:38:47 PM
                • Photons have no mass, but they do have momentum, and it is conserved. (n/t) - ER - 4/20/2008 1:19:28 AM
                  • I stand corrected. (Though I don't understand it. The quantum world is very odd.) (n/t) - alcaray - 4/20/2008 2:23:04 AM
                    • Photons are electric and magnetic field packets. - et - 4/21/2008 8:04:54 PM

                        • Epiphenomena yes, period. - ER - 4/21/2008 1:45:13 PM
