Temperature is not invariant. It transforms as
T' = T * (1 - v^2/c^2)^(1/2)
This does appear to raise an interesting puzzle. Suppose I have a
thermometer maintained at the triple-point of water. Presumably a passing
observer would agree that it reads 273.16 K (if necesary it has a digital
radout) and that I do have water vapour, ice and liquid water all
coexisting. How would she interpret T'?
