This discovery changed the attitude of the Physics Section of the Nobel Prize Committee towards quantum mechanics. The prizes for Heisenberg and Schrödinger were unfrozen, but by then, Dirac was also considered worthy of the Nobel Award, which he shared with Schrödinger.

Extending and Applying Quantum Mechanics
Heisenberg’s intellectual achievements during the year 1925-1927 alone could have given him a place in the pantheon of modern physics.

Experiments at CERN keep pushing it to extreme regimes, and time and again, it proves astonishingly accurate.

To celebrate 100 years of quantum mechanics, the CERN Courier looks back at the impact of this theory and examines how it keeps delivering new puzzles, experimental ideas and technologies. The controversy was often casted in terms of wave-particle duality, for the central ontological objects of wave mechanics were waves, while Heisenberg pointed out that the particle picture was equally valid in other empirical domains.

But before getting into the details we need to explain briefly about the two-slit experiment.

The two-slit experiment

In this type of experiment there is a barrier with two holes or slits. Biographical Memoirs of Fellows of the Royal Society 23: 213–251

Pais, A. (1986) Inward Bound Of Matter And Forces In The Physical World.

But most physicists believe nature itself is uncertain.

Intrinsic uncertainty was central to the way German physicist Werner Heisenberg, one of the originators of modern quantum mechanics, presented the theory.

He put forward the Uncertainty Principle that showed we can never know all the properties of a particle at the same time.

For example, measuring the particle’s position would allow us to know its position.

Brown, L., Pippard, B., & Pais, A. (Eds.) . Modern theoretical physics, and its pillars relativity and quantum mechanics, was the main target of their hate campaign built over nationalistic sentiments.
The ambiguity surrounding some of Heisenberg’s actions during the Third Reich, however, cannot affect the fact that Heisenberg was undoubtedly one of the most important theoretical physicists of the 20th century who made enormous contributions to the establishment of one of the building blocks of our current physics knowledge: quantum mechanics.

Heisenberg at the Juncture Between Old Quantum Theory and Quantum Mechanics
Werner Heisenberg was born in Würzburg on December 5, 1901, in a family belonging to the German educated middle class (Bildungsbürgertum), which considered culture as a mean for the cultivation of the self.

This nuclear theoretical scheme entailed that the neutron was a sort of proton-electron composite, although he did not explicitly address the problem of the neutron structure. The reason for Operation Epsilon, as the plan was called, was that the allied forces wanted to discover how far German scientists had progressed in the pursuit of atomic energy and nuclear weapons by recording their private conversation.

The result was that within a few months many outstanding scientists (including Einstein, Born, Bloch, Eugene Wigner, Hans Bethe, James Franck, Walter Heitler, Fritz London, and Otto Stern) pursued their academic career in other countries. Vol. 2. There, he built a department which attracted many talented students and postdocs eager to work with Heisenberg, including Felix Bloch, Edward Teller, Rudolf Peierls, Isador Rabi, and Ettore Majorana.

When Heisenberg arrived in 1920, Sommerfeld was occupied with the quantum theoretical explanation of the anomalous Zeeman effect—the splitting of the multiplets when a radiation source is placed in a magnetic field. Moreover, he complained that the contributions of Born, Jordan and Kramers had been neglected. He made use of the notion of inner quantum number j, which Sommerfeld had recently introduced to account for the spectral patterns of the anomalous Zeeman effect by means of the selection rule Δj = ±1.

To overcome the difficulties emerging in the quantum field theory of electromagnetic interactions, in 1938 Heisenberg proposed the introduction of the quantization of space and the related concept of fundamental length. In 1928, he put forward an explanation of ferromagnetism by making use of Pauli exclusion principle and of his earlier work on the exchange interaction for the electrons’ wave function in the helium atom.

There, Werner Heisenberg and his older brother Erwin attended the eminent Maximilian Gymnasium. Twentieth century physics (Vols. With Born’s probabilistic interpretation and the further development of the transformation theory by Dirac and Jordan, the very understanding of concepts such as position and momentum of particles in the quantum mechanical framework could not be easily related to their classical meanings.
