Andrew J. Hanson (born 1944) is an American theoretical physicist and computer scientist. Hanson is best known in theoretical physics as the co-discoverer of the Eguchi–Hanson metric,[2] the first Gravitational instanton. This Einstein metric is asymptotically locally Euclidean and self-dual, closely parallel to the Yang-Mills instanton. He is also known as the co-author of Constrained Hamiltonian Systems[3] and of Gravitation, Gauge Theories, and Differential Geometry,[4] which attempted to bridge the gap between theoretical physicists and mathematicians at a time when concepts relevant to the two disciplines were rapidly unifying. His subsequent work in computer science focused on computer graphics and visualization of exotic mathematical objects, including widely used images of the Calabi-Yau quintic cross-sections used to represent the hidden dimensions of 10-dimensional string theory. He is the author of Visualizing Quaternions[5] and Visualizing More Quaternions.[6]
