Energy and temperature are related to each other assuming the validity of a perfect gas law [math]pv=NkT[/math], where p is the pressure, v is the volume, N is the number of particles, k is Boltzmann's constant, T is temperature in kelvins. For N=1 particle (a single red blood cell, RBC). Our objective is to find the size of a single RBC using the zero point energy [math]\frac{1}{2}\hbar \omega_0[/math] and equating to [math]kT[/math]
[math]\frac{1}{2}\hbar \omega_0=kT[/math]
and using the fact that linear frequency is [math]\omega_0/2\pi[/math] and body temperature at 310 kelvin and the size of a single RBC is the linear frquency divided by the speed of light. The answer for the size of a single RBC is 2 microns, which is roughly the magnitude of the time axis.
