Adam Henderson

“One of the principle objects of theoretical research in any department of knowledge is to find the point of view from which the subject appears in its greatest simplicity.” - Josiah Willard Gibbs

This is the core thread of my research / professional career across Theoretical Physics (Quantum Gravity & General Relativity), applied math, machine learning, and software engineering.

List of Publications from my quantum gravity era. Without the academic pressure to write papers I am less and less inclined to share research.
