Unfortunately, few Caltech classes have lectures that are actually worth it to be posted online (unlike the MIT ones, who are IMO far superior in teaching quality, for the most part)
I attended Caltech about 35 years ago. I kept my notes, but looking at them now without recalling the context of the lectures makes them a bit on the incomprehensible side.
I sure wish those lectures had been recorded and I could refresh my memory on the more interesting ones.
I've also seen some of the MIT online videos, and my recollection is the Caltech lectures I attended were of comparable quality.
