I read this years ago in a collection of best science fiction stories.
I vaguely remember that the story is told by a mother to her daughter in the form of a letter (or letters). The mother works (as a linguist if I remember right) in a project that involves understanding some aliens, who do not share our conception of time. To the aliens life is static, all things happen at the same time, or something like that. At some point the author also talks about how light travels in air and water in such a way that it minimizes the amount of time it takes from A (in the air) to B (in the water).
I was intrigued by the alternative perception of time in that story, and wanted to read it again. Thank you for your help.
