Density Shift II. From Energy to Pi

This second volume continues the model of density shifting and applies it to the concepts of energy, temperature, and time. Through mathematical derivation and physical examples it is shown that energy does not exist as an independent quantity, but must be understood as an expression of dynamic spatial structure. In addition, the volume presents an alternative derivation of Pi, which is not based on geometry but on density shifting.
The work can be read independently, but at the same time connects content-wise to Density Shifting - Structure and Dynamics of Space.
