Talk:2989: Physics Lab Thermostat

Assuming I did the math right (Units proved the units worked out, but I wouldn't otherwise assume that), holding the energy constant at "room temperature with the normal, global Boltzmann constant" this thermostat varies from 13°C (56°F) on the left to 28°C (82°F) on the right. Holding the temperature constant gives a much harder to interpret range of energies from 4.2 zeptojoules on the left to 4.0 zJ on the right. Turning those back into temperatures with the normal Boltzmann constant gives 29°C (84°F) to 15°C (59°F). Given the reversed scale, I'd assume the former is the intended interpretation, and this thermostat has no effect on local thermal energy, it just adjusts the temperature scale so the number on your (local physical constant variance-compliant) measuring device matches what you asked for. 162.158.62.243 05:28, 24 September 2024 (UTC) Will

No matter the scale, I'm sure glad that this one doesn't go up to 11. Zaktduck (talk) 07:56, 24 September 2024 (UTC)

Looking at the page history, I'm wondering if the "edit conflict" didn't kick in for some people. If this edit was performed over at least half an hour (quite possible), it would seem that useful edits (submitted after the start of that big addition) got wiped out. Seems unlikely that warnings happened but were deliberately over-ridden. I know this can sort of happen very soon after article creation (usually doubling-up 'first' edits), but it should have highlit any inadvertant re-editing of an interim-changed paragraph. I generally thought. 172.70.85.18 09:39, 24 September 2024 (UTC) ((Ironically, I got hit by an edit-conflict just now, someone having removed linefeeds above where I'm merely appending this!))

I don't understand it the same way as you guys. Through setting the Boltzmann constant to k=1.380649×10−23 Joules per Kelvin, it's actually the Kelvin that the SI is setting. Thus, changing k in an unchanged universe changes the definition of the Kelvin, and (presumably) of Celsius or Fahrenheit too, meaning that the "temperature" reading of the room is changed without any need for heating or aircon, it's just the number which is adjusted to whatever people ask. --172.71.164.106 10:25, 24 September 2024 (UTC)

I like this explanation. We have a thermostat like that where I work. The numbers change, but the actual temperature does not. --162.158.158.188 11:27, 24 September 2024 (UTC)

As I read it, yes it just changes the thing that relates heat to temperature (thus not changing the quantity/quality of heat, but I am not convinced that the derivative idea of Temperature doesn't have some latent effect upon the experience. The additional amount of heat in a cinder might ignite some flammable substance, the same additional heat in a brick would be barely above its normal temperature, for example. Thus conceivably the temperature from the concentrated heat-source has more bearing upon what results than the less dense 'additional heat' with lower temperature that may never invoke the vapour-threshold/flashpoint.

Without being able to divorce or disassociate the interdependency (together with density/heat-capacith/etc), I can't be sure that such weirdness won't happen, and would not be surprised if things did (e.g. key phase-changes shift around). Like making inertial and gravitational mass independantly evaluated from each kter (if possible) would have certain real-world implications. (As well as hint that there's far more fundamental 'physics' at work than it is assumed that either/both currently are, in either newtonian or einsteinian respects.)

I think the explanation can cover both "just recorded different" and "changes physics" in a broad scope (which is somewhat hinted at right now). But it might be in the eye of the reader (and editor) how well it does that. 172.70.86.38 12:26, 24 September 2024 (UTC)
