If by chance you missed it, there is a glossary at the end of the book. (I've seen some comments from people who didn't notice until they finished it.)

Also, if you enjoyed the Shaftoes and Waterhouses of Cryptonomicon, consider putting the Baroque Cycle before Seveneves.

I didn't notice the glossary and I am actually glad I didn't. By the end of Anathem all of the strange names for things become second nature and you understand from the context what their meaning is. It is almost like what happens when you learn a new language and are able to think in that language.

I'm reading an ePUB, so hard to flip back and forth. Probably easier just to try to drink from the proverbial firehose until you can internalize it.
