	During my time at P.W.D. I happened to study the crude early works of using electrical grids for calculations, when I realised that in fact the terminology and formulae used by Electrical Engineers for grids and electricity was identical to a Structural Engineer for structural grids. To prove this I had an Electrical Engineer from a different section of the P.W.D.A.D. using his mathematics etc. to design a structure and at the same time had one of my Structural Engineers design the same structure the result was both designs were virtually identical. So I am categorically prepared to say that the calculations for the flow of force, electricity, and liquid, through their individual grids will in fact be identical.		During my time at P.W.D.

	Sometime before this, I had become intrigued in the mechanics of a doubly curved anticlastic surface used as a roof construction over large clear areas, named 'Hypars' a derivative of Hyperbolic Paraboloids. These were normally built in reinforced concrete where simultaneous tension and compression exist; this would result in shear being design criteria as stated in much of the literature.
