I've watched a few of these just for fun. They are very watchable even if, like me, you don't have the first clue about the actual mathematics he uses. He explains enough of the physics in words that you can just let the forumlae wash over you and not worry about it.
The maths is kept into self-contained bits, so a lecture will typically be 40 minutes of words and pictures, then 20 minutes of calculation. I'm sure if you do get the maths then it will be perfect for you, but I encourage you to watch it anyway.
Overall, highly recommended, especially the cosmology ones.
EDIT: actually my memory is probably biased towards the cosmology course. I imagine the classical/statistical mechanics stuff does have a lot more maths running through each lecture.
