Einstein once said that 3D solid geometry was nothing but physics.
We assume that the following unconventional formulas are products of the statistical transition matrix chains B:
i- Two 3D bodies of different shapes can only have the same volume V if they have exactly the same area A.
ii- The minimum value of the V/A ratio of a body of 3D geometry is equal to 1/6 and is satisfied by cubic geometric shapes.
iii-Two three-dimensional bodies of different shapes and of different materials can only have the same mass m if they both have exactly the same volume V and the same area A.
iii- Sabine's imperial formula for the reverberation time Tr in sound rooms:
Tr= constant * V/s A.
is deduced in a regular way via the chains of the matrix B.
. . . etc.
