Thanks for your comment. For people new to physics (I am one of them) I can't recommend strongly enough Leonard Susskind's 'The Theoretical Minimum' courses -- http://theoreticalminimum.com/courses . I'm currently going through the one on Special Relativity and EM concurrently with Hestenes' text.

You could also check out Sean Carroll's Spacetime and Geometry. It's my favorite textbook.

Supplement with the second half of Wald's book for exploring some concepts

This is great, thanks so much for linking this. I acquired a taste for mathematics way too late and didn't get a chance to grasp physics at university because of it, the Theoretical Minimum courses seem to be exactly the second chance I was looking for.

Awesome! By the way, there are also books that accompany the first three courses:

https://www.amazon.com/Classical-Mechanics-Theoretical-GEORG...

https://www.amazon.com/Quantum-Mechanics-Theoretical-Leonard...

https://www.amazon.com/Special-Relativity-Classical-Field-Th...

If you get the first one, make sure to get the one titled 'Classical Mechanics' and not just 'The Theoretical Minimum' as the former is a more recent printing with many corrections.
