In this case the conventional policy of “Sustainable Development” is not sufficient to avert the impact of diminution of precipitation on Israel’s water supply. Instead, a policy of “Progressive Development” is proposed, which aims to exploit, stage by stage, first the water resources most available and at lowest cost until they are ex-hausted. Once this stage is under execution, progressive steps are taken to develop more costly resources by advanced methods of exploitation. A case study of such a development plan is the controlled deterioration of the water quality of the coastal plain aquifer of Israel.展开更多

Its degrees of freedom are arithmetical (+-) and logical (if-then) forward and backward steps. While Space refers to gaps in distance, Time refers to change in instances, Information refers to a sequence of notions measured by the number of steps made (or bytes used) by a computer in order to perform (de-scribe or solve) a certain logical sentence or a sequence of logical sentences. In the attempt to quantifiably formulate the incorporation of Information into physical laws, we refer to Hamiltonian extended stationary principle in terms of Space, Time and an additional degree of freedom, suggested as an information state. The obtained Euler equation is demonstrated for the case of a thin rod under longitudinal vibrations, investi-gated by dimensionless analysis. It is shown that depending on the value of information and its rate, one may obtain dominant forms conforming to Poison’s equation in Space vs Information, wave equation in Time vs Information and the expected wave equation in Time vs Space.展开更多
