Little epochs replace one of the epoch slots for a week, and on average occur every 5 weeks. Structure of social spaces Physically, AKG can be interpreted as a sum of many "little schools". A LS is a self contained social space with a classroom for each stack, a kitchen, a central social area, bathrooms and a teacher's lounge. Students are allowed to make the space their own with changes and decorations, but the physical integrity and cleanliness of the space must be maintained. Students leave the LS for things like clubs and classes that require special equipment (music, P.E., science, etc.) but they spend the vast majority of their days here. Whenever a year graduates, their LS is renovated, to make way for the next year coming in September. School traditions Sleep over Students in AKG frequently have in-school sleepovers, either with their patronal group or their club. During the night, the school is almost completely empty, and students can do whatever they want (within reason, of course). Common favorites are playing hide and seek in the labyrinthine halls, watching movies, or playing dodgeball. One teacher has to be in the building with the students for supervisory purposes. Students bring their own sleeping bags, and sleep on lobby-couches, or gym mats. The robotics team frequently does sleep-ins before competitions for additional crunch time, so much so that a running joke amongst students is that the robotics team lives in the building and never leaves. Patron picking First year students have a special introductory camp, the purpose of which is to let them get to know the other students and the patrons. At the end of the camp, students rank the patrons on a scale, according to how much they want to be their student. On the last night, the patrons are up all night sorting people into patronal groups. On the final morning, students learn of their patronal group for the next few years during a ceremony, which is usually designed by the patrons. Once the groups are made, they eat breakfast together to get to know each other even better. Science Night Science Night is a 4–5 hour program in October, completely open to the public. Guests can get to know various fields of science, experiments, and the lives of important intellectuals. Activities are organized either by relevant clubs, or vetted outsiders. Anything from electronics to chemistry can
