edit·history·watch·refresh Stock post message.svg To-do list for Temperature:

Restructure according to the guidelines proposed in Wikipedia:WikiProject Science, ie. with the following main sections:

  • Introduction : importance of temperature for life and humans; brief history of the understanding of temperature
  • Temperature in practice: (avoid theory here)
    • Types of temperature: perceived vs real, typical values, macroscopic vs microscopic, temperature of light, negative temperature
    • Units of measure
    • Temperature in the Universe: temperature changes since the big bang
    • Temperature in everyday life: common measuring devices; importance for life
    • Temperature in industry: importance in chemical processes; sample processes with very low or high temperature
    • Temperature in science: precise measuring devices; role in many scientific theories
  • Temperature theory: discuss thermodynamics, why temperature cannot go below 0...
    • Basic concepts
    • Advanced concepts
  • History: explain how the concept of temperature evolved over time

[edit] some or most of the world

Editor 219.89.117.203 changed "Some of the world" to "Most of the world', but did not offer a reliable source for change. I have therefore reverted the change.

For all I know, the change by editor 219.89.117.203 may have been for the better. But Wikipedia policy is that such a change should be supported by a reliable source, for the better or not.

Dear editor 219.89.117.203, you are of course free to make the change again, but if you do, you should supply a reliable source for it. A reliable source is not just any source that agrees with you, but one that can be reasonably verified as giving reliable information on the point. If you do not provide a clearly reliable source for a change, I will oppose the change.Chjoaygame (talk) 02:11, 4 January 2012 (UTC)

[edit] the large majority of people in the world

The problem here is not as to the truth or otherwise of the edit, but is as to its conformity with the Wikipedia requirement for reliable sourcing. This is the same as for the previous edit commented on just above. If you want to make an edit like this, you need to provide a reliable source for it. It is no easy thing to provide reliable sourcing, because it calls for careful assessment of source reliability.Chjoaygame (talk) 02:50, 8 January 2012 (UTC)

[edit] microscopic particles?

"average speed of the microscopic particles that it contains" 

suggests particles that can be seen with a microscope. That is, particles which are bigger than nano-paricles, but smaller than milli-metres.

Perhaps that should read: "average speed of the atomic particles that it contains" 203.206.162.148 (talk) 01:32, 25 January 2012 (UTC)

I have removed the word "microscopic" - By the equipartition theorem, a thermalized particle of any size will have a kinetic energy of 3kT/2.PAR (talk) 04:12, 25 January 2012 (UTC)

[edit] Heat 'flows'?

The 2nd line of the article has "Heat spontaneously flows from bodies of a higher temperature to bodies of lower temperature". this is the rather outdated caloric theory. It should be "Energy is transferred from bodies with a higher temperature to those with a lower temperature". Heat in measured by temperature and thus is is not a substance that can 'flow'. There are many ways a body can change its temperature, none of them involve 'flowing'! It has been said that Wikipedia is not for scientists, this reads like 'keeping the ignorant in their place' to me. --Damorbel (talk) 12:12, 25 January 2012 (UTC)

[edit] Wavelength for black-body radiation of bodies with 0 temperature

It should be noted that the entry "Infinite" for the wavelength of a body of 0 temperature is pretty bogus, as such a body simply emits no black body radiation. So it should either be left empty or read something like '-'... — Preceding unsigned comment added by 82.139.196.68 (talk) 15:39, 5 February 2012 (UTC)
