A significant discrepancy;exists between the frequency measured by Planck?s derivation constant and;Wien?s displacement constant for black body radiation at a particular;temperature. It is argued that this discrepancy lies in the way the equations;evolve from the works of Planck and Wien. However on deeper inspection I have;found that this discrepancy is due to a rotational factor of 2Pi? 10 -7?;137.036.
