His most important paper on optics, entitled "An essay towards a dynamical theory of crystalline reflection and refraction", describes a potential function for a dynamical theory for the transmission of light. MacCullagh found that a conventional potential function proportional to the squared norm of the displacement field was incompatible with known properties of light waves. In order to support only transverse waves, he found that the potential function must be proportional to the squared norm of the curl of the displacement field.  No birth date. Pic.
