It has been found that there is a direct and indirect measure- 1905. ment of that number. To perform such a measurement, a selection was made of some http://dx.doi.org/10.4236/jamp.2016.410192 mathematical and physical quantities which within themselves contain a number π. π Received: September 13, 2016 One such quantity is a straight angle Pi, which may be expressed as Pi = rad. By Accepted: October 17, 2016 measuring the angle, using the direct method, we determine the number π as π = Published: October 20, 2016 arccos(−1). To implement an indirect measurement of the number π, a system con- sisting of a container with liquid and equating it with the measuring pot has been Copyright © 2016 by author and conceived.
