Absolute zero is inaccessible because it takes infinite work
to reduce a temperature to that point. It always takes the
same work to halve a temperature. This means that there
is a potential logarithmic unit to be derived from the
energy used to reduce temperature from the triple point of
water to half that temperature at -136.575 degrees C.
I therefore propose that whereas exactly 136.575 units be
used to cover the difference in temperature between the
tripe point of water to -136.575 degrees C, a further
136.575 units cover the difference between that and
-204.8625 degrees C, and so forth, and that within these
intervals the temperature units gradually contract as it
Above freezing, the reverse happens, so the old 68.2875
degrees above freezing becomes the new 137.575 units
above freezing, and so on.
This would be a measure of the real energy required to do
this, and also make cryogenics much more impressive. It
would also make it less likely that people would talk about
halving the temperature when they in fact mean halving
the temperature in degrees C or F.
If negative mass exists, it will have negative temperature, which is a measure of average molecular kinetic energy. The equation for kinetic energy makes that quite obvious. [Vernon, Jan 14 2016]

||This already exists, and is a useful quantity in thermodynamics, but it doesn't have a fancy name and is just referred to as "beta". It is defined to be 1/(boltzmann constant * temperature in kelvin)
