An irrational and transcendental constant representing the ratio of the circumference of a Euclidean circle to its diameter; approximately 3.1415926535897932384626433832795; usually written π
An irrational constant representing the ratio of the circumference of a circle to its diameter; approximately 3.1415926535897932; usually written π, where pi x diameter = Circumference
Principal Investigator; the primary person responsible for the design, scientific/technical conduct, administration, and reporting of a sponsored research project
The letter Π, π, as used to denote the number or quotient approximately expressing the ratio of the circumference of a circle to its diameter; also, the quotient or the ratio itself
Public Inquiry by Traffic Commissioners Traffic commissioners when necessary, hold Public Inquiries, in particular to consider the environmental suitability of HGV operating centres and the possibility of disciplinary action against operators who have not observed the conditions of their licenses
Pi is a number, approximately 3.142, which is equal to the distance round a circle divided by its width. It is usually represented by the Greek letter ƒÎ. private investigator. To become jumbled. a number that is represented by the Greek letter (兾;) and is equal to the distance around a circle, divided by its width (From the name of the first letter of periphereia ). In mathematics, the ratio of the circumference of a circle to its diameter. An irrational number (See also transcendental number), it has an approximate value of 3.14, but its exact value must be represented by a symbol, the Greek letter . Pi is used in calculations involving lengths, areas, and volumes of circles, spheres, cylinders, and cones. It also arises frequently in problems dealing with certain periodic phenomena (e.g., motion of pendulums, alternating electric currents). By the end of the 20th century, computers had calculated pi to more than 200 billion decimal places

Each NERSC repository has a single Principal Investigator, or PI for short The PI is the scientific head of the project supported by an allocation of NERSC resources Although the PI may delegate some responsibilities to account managers, he or she is ultimately responsible for procuring and managing the repository
Symbol P, denotes a constant value of 3 141592... Used in the calculation of radius, circumference and other calculations relating to circles and spheres
The quotient pi cannot be expressed as a root of an algebraic equation; and from this fact follows the impossibility of the quadrature of the circle by purely algebraic processes, or by the aid of a ruler and compass
