to the activity of roof and tunnel hacking, where students explore building rooftops, steam tunnels, and utility shafts. Activities MIT has over 380 recognized student activity groups. These are mostly governed by the MIT Association of Student Activities. Educational Studies Program The MIT Educational Studies Program (ESP) was created by MIT students in 1957 to make a difference in the community by sharing MIT's knowledge and creativity with local high school students. Since then, its programs have grown to support well over 3000 students each year. ESP classes are developed and taught by MIT undergraduates, graduate students, alumni, and members of the local community. ESP's students are given the chance to learn from passionate and knowledgeable teachers; ESP's teachers can gain experience developing their own curricula with access to students with strong desires to learn. ESP pioneered Splash, a large, short-term academic outreach program that involves over two thousand teachers and five hundred classes. The program has grown in popularity and attracted students from well beyond the local Boston area. Splash emphasizes having a diverse range of class topics, covering a variety of academic fields as well as non-academic games and practical skills. In 2007, ESP alumni founded Learning Unlimited (LU), a non-profit organization dedicated to supporting educational opportunities like Splash at universities throughout the United States and beyond. LU provides assistance, including mentorship and software support, that helps new Splash programs start successfully. there are over thirty LU affiliated programs in the United States and one in the United Kingdom. Lecture Series Committee The Lecture Series Committee (LSC) organizes weekly screenings of popular films as well as lectures by prominent speakers. As one of the few Institute-wide gatherings on a weekly basis over the years, LSC movie screenings have developed and retained a few quirky traditions which sometimes befuddle outsiders. One unspoken tradition relates to the 1950s style introductory film clips that announce "coming attractions" movie trailers. When stereophonic sound was a new development in movies, the movie trailers would be preceded by a clip announcing, "Coming Next Week", followed by "In Stereo". For whatever reason, MIT audiences would spontaneously read the announcements aloud, in unison. This eventually became such an ingrained habit that, even though LSC discontinued screening the "stereo" announcements, the audience would intone the (now unseen) words. Even though LSC has replaced the sound system several times since the appearance of stereo sound, and now operates
