A really good book, for people interested in learning about lie groups.

I was studying linear algebra and was reminded of this book that I bought some time ago. I haven't finished it (2 chapters in) but the introductory concepts coupled with my random study of SU(2) group and its algebra gave me some rudimentary insight into the utility of Lie Algebra's and why it was good enough to be used for Pauli matrices and describing spin, but not good enough to be true vectors in 3-d+1 time space.

For those interested, there is also a good channel that goes over the boom in-depth and you can pretend youre a graduate student getting lectures and working problems from the book as homework.
