Since it was first discovered, physicists have attempted to find the fundamental physical cause of the fine structure constant. The fine structure constant appears in many different physics relationships and can be expressed in terms of a number of combinations of different physical constants. This leads to some debate over what is the most fundamental representation of the constant. In this paper it is first shown that the unit charge can be viewed as the polarizability of space over a surface area surrounding a unit charge. The polarizability of space is in turn determined by the van der Waals torque of the quantum field. That torque regulates the rate of rotation of the quantum dipoles of standard model quantum field theory as each quantum dipole is polarized. Then, based on the well-known relationship between the charge squared and the fine structure constant, it can be readily shown that the fine structure constant is the total volumetric polarization of the quantum field due to a single unit charge. This shows that the fine structure constant can be fundamentally derived as an effect due to fundamental electrodynamics of the quantum field.
