The perimeter of a circle, often called the circumference, is proportional to its diameter and its radius. That is to say, there exists a constant number pi, π (the Greek p for perimeter), such that if P is the circle's perimeter and D its diameter then, =.

**Perimeter**, ground must be terraformed before buildings can be built on it. Some weapons can distort the ground, which will cause constant damage to buildings until the ground is re-terraformed. Buildings must also be placed on a power grid formed by Energy Cores linked to the player's Frame. A building that loses connection to the power grid stops working and may be captured by an enemy player who connects it to their own Energy Core network. Thus destroying Energy Cores to disconnect parts oHumanity has undergone radical changes in society. Scientists and spiritual leaders became one and the same, calling themselves Spirits. The Spirits, foreseeing the inevitable destruction of Earth due to the ravages of our time, directed scientific efforts into the discovery of a new plane of existence: the Psychosphere. The Psychosphere acted as a conduit, providing means to reach another, untouched world, a new Promised Land, by jumping between flat worlds within the Psychosphere. The Psychosp

**Perimeter Institute for Theoretical Physics is an independent research centre in foundational theoretical physics located in Waterloo, Ontario, Canada.**It was founded in 1999. The Institute's founding and major benefactor is Canadian entrepreneur and philanthropist Mike Lazaridis. The original building, designed by Saucier + Perrotte, opened in 2004 and was awarded a Governor General's Medal for Architecture in 2006. The Stephen Hawking Centre, designed by Teeple Architects, was opened in 2011 aLazaridis' initial donation of $100 million was announced on October 23, 2000, believed to be the biggest private donation in Canadian history to that point. A subsequent personal donation of $50 million was made on June 4, 2008. Research operations began in 2001. Along with its research activities,

It is a meta-repository search tool of scientific talks beyond what is produced at PI and aims to "revolutionize the world of scholarly communication in the way that the arXiv has done for print scientific papers". Apart from PIRSA's existing content, SciTalks indexes videos from other institutions, such as CERN, Simons InstituPerimeter’s educational outreach team’s activities include a monthly public lecture series, a two-week summer camp for the world’s top science students, a series of in-class resources, week-long professional development workshops for science teachers, cultural activities with local and international artists, an online archive of educational resources, an extensive network of science teachers to share content across Canada, and many other special events and science festivals ...
