Fundamental Temperature

#Physics

$\displaystyle \tau=k_{B}T=\left( \frac{ \partial \sigma }{ \partial U } \right)^{-1}$

• Has units of energy
• $\displaystyle k_{B}$ is the [Boltzmann constant]
• $\displaystyle T$ is the temperature
• $\displaystyle \sigma$ is the [fundamental entropy]
• $\displaystyle U$ is the total energy of the system and environment
