The Motion of Light in Water: Sex and Science Fiction Writing in the East Village is an autobiography by science fiction author Samuel R. Delany in which he recounts his experiences as growing up a gay African American, as well as some of his time in an interracial and open marriage with Marilyn Hacker.
 It describes encounters with Albert Einstein, Bob Dylan, and Stokely Carmichael, a dinner with W. H. Auden, and a phone call to James Baldwin.

 In section 17.4 of the University of Minnesota Press edition, he describes the event and its venue, and speculates on its artistic significance.
