Critical phenomena

introduction

•   In this sense, the thermodynamic functions seem to display scale invariance around the critical point (for systems that have a critical point!), with the scaling variable t=(1-T/Tc).
• Note that the logarithm y=log x obeys y(ax)=y(x) + log a.
• It is scale invariant with exponent 0 (and a scale-dependent shift.) 
• This is related to the famous formula\(\lim_{p\to 0}\frac{x^p-1}{p} = \log x\) which shows that logs are a special case of power law functions with power 0.
