Whoever built the Great Pyramid knew, among many other things, the precise circumference of the planet, and its distance from the sun, the length of the year to several decimals, and how to utilize the value of pi in its construction. Coded within its geometry is the secret of universal measure. The question remains as to the purpose that it was built. Through discovering the measurement used by its architects, this book uncovers the geometric code to its hidden meaning, a key to opening the door to a new science that bridges the two worlds between the seen and the unseen, the manifest and the unmanifest.
