Most temperature scales are linear lines. This means that there are lots of numbers.
It also means that you can specify temperatures fairly easily that cannot possibly exist (e.g. -500°C)
The concept of absolute zero, where there is zero energy in a system, leads to an obvious solution: K, where
there are no negative temperatures but the line leads off into infinity.
Now I believe there must equally be a maximum temperature, to do with quantised energy levels, plancks, beams, joists and secret lap dovetail joints. All we need to do is to find the maximum physically possible temperature and then we set this as 1 on our scale, and we set 0 as absolute zero, and then we can specify any temperature possible using a decimal or fraction between 0 and 1.
I assume this will be inconveniently biassed towards high temperatures - hence the idea of using a log scale kind of thing.

If you had a piece of high temperature kindling and a cool
temperature piece of kindling, could you split the difference? |

Absolute zero is a theoretical point where there is no molecular motion. It cannot be reached because it would mean defining both the location and speed of a particle. Is absolute hot the theoretical point at which the movement speed of individual particles is the speed of light? |
|

[AusCan] a good question, I'm glad you axed it. |
|
| |
[Voice] //absolute hot// good terminology. But we don't say "absolute cold" so perhaps using my scale, we should call it "absolute one" instead. Also, not sure its as simple as that since photons travel at the speed of light but are not at absolute hot. (I don't think...? Help me out here?) |

Suppose there's a linear relationship between joules and
temperature increments for a given element or compound
(specific heat capacity). Suppose there's a theoretical
maximum to the amount of energy you can pump into, say,
hydrogen, before it ceases to be hydrogen. (See the link about
firing lasers into plasma). Suppose that, by the time it's ceased
to be hydrogen, it's also ceased to have any comprehensible way
to have its temperature taken (or even defined). Suppose that
hydrogen is the proper reference substance here, because
atoms get more fissile as they get bigger. |
|
| |
Given all those suppositions, there might be a relevant maximum
related to the specific heat capacity of hydrogen. |
|
| |
Alternatively, maybe the best starting point would be the Big
Bang - or would that give you a theoretical temperature of infinity
Kelvin (coinciding with a finite amount of energy in a volume of
zero)? |
|
| |
Any estimates for room temperature? 10^-34 maybe? |
|
| |
You chose the logginess factor to make room temperature a sensible number. Every temperature can be sensible AND the scale can have a rational start and end point. |

// It also means that you can specify temperatures fairly
easily that cannot possibly exist (e.g. -500°C) // You
stated this as a problem, but your "solution" seems to me
to make that even worse. |

It seems to me there ought to be a way to define the
temperature scale such that negative infinity corresponds
to what we call absolute zero. That seems like it could be
useful since we're never actually gotten there. So set the
scale so some easily achievable low temperature is -1000
and maybe the current record is -1,000,000, and maybe in a
few years or decades someone will get down to -10^9. I
like the current system of positive infinity relating to
something unattainably hot. If scientists do sometime
discover an absolute maximum temperature we can just
recalibrate the scale again... So for a first pass let me
throw out: |
|
| |
Tk = Temperature in Kelvin |
|
| |
Th = Temperature in Halfbakins. |
|
| |
Th = -273.15/Tk + Tk/273.15 |
|
| |
That would give us 0C = 0H, but we'd need a scale factor to
make boiling boiling temp = 100, so: |
|
| |
Th = 157.707 * (-273.15/Tk + Tk/273.15) |
|
| |
Room temperature of 25 only changes to 27.66. |
|
| |
Liquid hydrogen boiling point is -2112. |
|
| |
Current record of 0.0053 K is -8.1 x10^6. |
|
| |
Sounds good enough to me. |
