The pivotal shift in Physics initiated by Erwin Heisenberg's seminal work in 1925 marked a significant departure from classical paradigms towards what is now known as modern quantum physics. Heisenberg's groundbreaking paper, "On the quantum-theoretical reinterpretation of kinematical and mechanical relationships," commonly referred to as "Die Umdeutung," heralded a radical transformation in the foundation of physics. By replacing the traditional religious notion of "Causality" with an atheistic concept of "Probability," Heisenberg's work revolutionized the field. The removal of "Causality" challenged the religious underpinning of physics, leading to a reevaluation of fundamental principles. This shift, epitomized by the Heisenberg Uncertainty Principle, transformed the deterministic worldview into a probabilistic one, sparking debates on the nature of existence and human agency.The ramifications of this paradigm shift extended beyond theoretical discourse. The ethical implications of scientific advancements, exemplified by the development of the atomic bomb during World War II, underscored the complex interplay between physics, morality, and political ideologies. The juxtaposition of Heisenberg's involvement in Nazi Germany's atomic research and Oppenheimer's leadership in the Manhattan Project highlighted the ethical dilemmas faced by scientists in wartime.Moreover, the integration of Heisenberg's Uncertainty Principle with Newton's Causality Principle rekindles discussions on the interconnectedness of Physics, Philosophy, and Theology. The quest for a unified framework underscores the importance of reconciling divergent perspectives to forge a coherent understanding of the universe. This synthesis seeks to bridge the gap between classical paradigms and modern quantum theory, offering new insights into the intertwined fabric of physical laws and metaphysical beliefs.

During the 5th Solvay in 1927 has been the famous discussion between Albert Einstein and Niels Bohr when Einstein declared: “God does not play Dice”. Formally this discussion was between Einstein and Bohr. But the real discussion was between Einstein and Heisenberg. Heisenberg the creator of the principle of “Fundamental Uncertainty”.
For creating a measurable Physics, we must first revisit its theoretical foundations. Deterministic Physics cannot be measured and therefore cannot be proven experimentally since an infinite amount of energy is required to confirm a Law of Physics to infinite precision. This “measurement problem” existed ever since Physics – centuries ago – slowly separated from its deterministic theological roots. Given the experimental successes of deterministic Newtonian Mechanics, deterministic Physics nevertheless became the law-of-the-land. The introduction of Quantum Mechanics in the 1920s threw a spanner in the works and re-emphasised the importance of that underlying measurement problem. Rather than removing Classical Physics' deterministic inheritance, however, the science community reacted by introducing deterministic postulates to make Quantum Mechanics “fit” the prevailing classical framework. Unphysical postulates like the existence of a wavefunction, assumed to be a “complete” description of a physical system, and its square was assumed to be “measurable”, created a series of problems at the core of Physics, which remained unresolved for more than a century. This (part-4) paper promotes a discrete uncertainty principle as the foundation of a Discrete Physics. Symmetric-sampling incorporates this discrete uncertainty principle from the onset and provides comprehensive rules for handling measurements and discrete computer representations of signals and functions. This principle applies to all of Physics, including classical Quantum Mechanics and General Relativity. The red line of this paper is to complete the original “X-ray-microscope” model experiment proposed by Heisenberg in 1927. Retracing Heisenberg’s original “Gedanken” experiment helps us pinpoint the deterministic flaws at the core of Classical Physics and Quantum Mechanics, while assessing a fresh comprehensive Discrete Physics.
