Hey, unrelated: Does anyone know why it seems MITx stopped offering new courses ~5 years ago? I'm still bummed out and check their page a few times a year.

(I can vouch for this class and the 2x2 one btw; great stuff; I'd recommend any of their math and science courses. The QM ones are especially good)

Well, the multivariable calculus series was released more recently. Work is ongoing for the 3rd part of that series.
