More than 1,500 bright-eyed freshmen arrive on campus today to join their international classmates, who moved in Sunday, for New Student Orientation (NSO).

Farm fledglings can look forward to the classic highlights, including departmental open houses, socials, convocation, The Real World, a Friday-night show with legendary bassist Victor Wooten and a taste of Stanford a cappella at the O Show. The traditional “Three Books” lecture and discussion feature Strength in What Remains by Tracy Kidder, The Spirit Catches You and You Fall Down by Anne Fadiman and Joyce Carol Oates’ 1996 short story “The Undesirable Table,” all works that deal with ethics and the presence or lack of privilege.

But this year’s six-day “Stanford 101” program has a green twist to complement the headliners, which comes as part of a growing effort on campus to be more environmentally conscious.

Students, advised to leaf through “A Student’s Guide to Sustainable Living at Stanford” before coming on campus, can opt for bus tours of the university’s eco-friendly practices, dine at “zero-waste” lunches and attend a lecture by biology professor Elizabeth Hadly on climate change.

NSO will also host special services for Yom Kippur, which begins Friday, Sept. 17.
