Learning about Lie groups
Actually, I'm having the hard time with Serre's book on Lie groups and algebras: the lack of motivation is my biggest problem. So, what would you suggest for a first, illustrative, but systematic and deep course on Lie groups? The lack of good books on Galois theory on my way is a different problem: too much formalism without much of results is what I've seen in Postnikov's "Galois theory" so far
As a little note on preferences: right now I'm enjoying the topology book of Seifert and Threlfall(with its geometric illustrations) and homological algebra by Cartan & Eilenberg(because of the well-understandable language of diagrams).
