Heisenberg argued that wave and particle are too exclusively different in properties, making the intrinsic wave-quantum unity of light impossible to visualize and describe by the language. He invented mathematical Quantum Theory to circumvent visualization and inadequacy of language. But mathematics too is a language to supplement description. He used it to superimpose hidden concepts leading to the Uncertainty Principle. In Unified Theory the wave & particle aspects of electromagnetic radiation and moving material particle coexist blended together as wave-quantum UNITY. This is also supported by experiments. The wave-or-quantum DUALITIES of Quantum Theory appear due to experimental limitations to observe only one and not both of the two aspects simultaneously. Conservation of mass-energy & momentum are inviolable. Matter?s creation from, or dissolution into,?nothing’ is unrealistic. So the Heisenberg’s Uncertainty Principle is rejected as unrealistic and new Principle of Null Action with universal applications is introduced, which is based on the conservation of mass-energy, momentum and?Action’. The Copenhagen interpretation of Quantum Theory is reappraised critically.
