The reasonable ineffectiveness of mathematics [point of view]

D Abbott - Proceedings of the IEEE, 2013 - ieeexplore.ieee.org
This article addresses the presupposition that mathematics is as effective as claimed and
thus remove the quandary of Wigner's" miracle," leading to a non-Platonist viewpoint. Also …

Vector geometric algebra in power systems: An updated formulation of apparent power under non-sinusoidal conditions
