Neal Stephenson's baroque 'trilogy'

The mix of science, history, speculation and story-telling makes the 2000 plus pages of these four books as entertaining as the best things I have ever read. Cryptonomicon was the first, set in the Second World War and the 1990s; the three others followed afterwards, set in the Scientific Revolution. Hugely, utterly satisfying. I cannot remember enjoying a book more. My only real disappointment with these books was that they came to an end.
