Now consider Betsy, the person driving the car. Betsy, in choosing her frame of reference, defines her location as the origin, the direction to her right as the positive x -axis, and the direction in front of her as the positive y -axis. In this frame of reference, it is Betsy who is stationary and the world around her that is moving – for instance, as she drives past Alfred, she observes him moving with velocity v in the negative y -direction. If she is driving north, then north is the positive y -direction; if she turns east, east becomes the positive y -direction.
Ironically, James felt that his lesser story was getting the credit that Roderick Hudson should have received but the test of time has shown Daisy Miller to be one of James's classics whereas Hudson is less acclaimed. The novella became incredibly popular; Howells commented once that he heard society dividing itself into "Daisy Millerites and anti-Daisy Millerites." By the early 1900s, the novella had been reprinted many times due to minor revisions James made for a New York edition. An unsuccessful play version was even published, first privately in England in 1882 and then in in Atlantic Monthly in 1883. In 1909, "James conscientiously attempted to supply for the definitive edition the psychological depth and nuances which he felt were lacking in the 1878 version?." Yet editors since, such as Geoffrey Moore, have felt that the 1909 edition clouds over the fine work of the original and tend today to print the version of 1878.
