Tenth anniversary

It was recently the tenth anniversary of the founding of this blog. My focus has long since shifted to the standard model. But mathematical progress here may in time affect those more practical theories too.

There is a paper today talking about “exact solvability of N=4 Yang-Mills”; but the author seems to mean only the classical theory.

For those who want to understand how interest in N=4 developed out of actual physics, “Electromagnetic duality for children” may help, by tracing a path from Maxwell’s equations, monopoles and dyons, and Montonen-Olive duality, to Yang-Mills with extended supersymmetry.
