## Pi equals 3.14159265358979323846264338327950288419716939937510…

An arc of a circle with the same length as the radius of that circle corresponds to an *angle* of 1 radian.

A full circle corresponds to an angle of 2π radians.

# Currently Pi equals

**3.14159265358979323846264338327950288419716939937510**… plus as of November 2017 when Peter Trueb’s computer finally, after 105 days, calculated 22,459,157,718,361 fully verified digits of pi. That is over 22 trillion digits!

- Pi ( π ) is the exact ratio of the circumference of a circle to its diameter.
**Pi is a constant**.- Pi is an
**irrational**number. - Pi is a
**transcendental**number. - Pi is a
**non-repeating**number – no pattern has been identified using computer analysis within over twelve trillion places. - Pi is a
**never-ending**number. - Pi within any equation makes the result irrational, never ending and never repeating.
- Pi is a dimensionless constant. It is a mathematical constant.

# We also believe…

- Pi is the simplest, most commonly-used dimensionless constant.
- Pi is the bridge between the finite and the infinite.
- The sphere is the first manifestation of spacetime defined as the Planck Length and Planck Time.
