Countable line arly ordered sets are easy to understand: these all turn out to be isomorph ic to some subset of the rationals\, but what about uncountable linear orde red sets? Some concrete things can be said\, but one quickly runs into the independence phenomenon: very often\, answers to natural questions will t urn out to be undecidable\, neither provable nor refutable from the usual a xioms that define the set-theoretic universe. We will survey some results shedding light on the classification and potential behavior of uncountable linear orders\, and finish by discussing some results obtained in research this past summer.
