Relevance of Knuth

I wish to know how relevant/beneficial studying books like Knuth's Art 
of Computer Programming is for a person working on languages like 
Java/Python. The applications are _not_ graphics related or scientific, 
but these are core Java networking servers, some J2ee work, a lot of 
design related work.

I glanced through these books recently and they seem highly math 
oriented to me (i dont have a math background).
Am i right in thinking that these concepts have already been taken care 
of while designing say the Collections frameworks. Would they be only 
useful for persons designing searching sorting algo's ?
Or would they help me write more efficient code in general.

Appreciate comments. BTW, Knuth isn't just one book. There are several 
volumes, and some he's still working on (quite daunting for a faint 
hearted person).
