The Work of Imagining Subatomic Particles in Early Quantum Mechanics

Sean Miller

Focusing on a selection of key texts from early quantum mechanics, the essay examines the concept of the quantum of action and the role it has played in the positing of the photon and electron as real objects within a supporting epistemological imaginary—an imaginary that stands metonymically for the objective world. Since physicists imagine themselves as a certain form of subject within the imagined world evoked by these texts, an encounter with subatomic particles as basic objects within that world entails a novel form of imagined work as well. The import of this novel subject and the work that it does with particles as objects qua objects depends, in large part, on the extent to which the physicists, while rhetorically subverting that imagined subject’s presence within the text, nonetheless privilege it as an ideal.Focusing on a selection of key texts from early quantum mechanics, the essay examines the concept of the quantum of action and the role it has played in the positing of the photon and electron as real objects within a supporting epistemological imaginary—an imaginary that stands metonymically for the objective world.

Quantum Physics: From Imaginary to Reality

Isabella Taylor

Quantum physics has long occupied a space between imagination and reality, captivating scientists and philosophers with its strange, counterintuitive principles: superposition, entanglement, uncertainty, and nonlocality. What once appeared as hypothetical mathematics now manifests in real technologies—lasers, semiconductors, superconductors, atomic clocks, MRI machines, and emerging quantum computers. This mini-review traces the conceptual journey of quantum physics from an abstract theory born in early twentieth-century thought experiments to a practical framework shaping modern engineering, computation, communication, and materials science. It highlights key developments in interpretation, experimental validation, and application, while reflecting on how quantum physics reshapes our understanding of nature, reality, and information. Although quantum mechanics remains philosophically perplexing, it has become a powerful and indispensable foundation for technological innovation. By examining how imaginary constructs transitioned into concrete implementations, this article illustrates the remarkable interplay between theory and experiment that continues to redefine what is possible.Quantum physics has long occupied a space between imagination and reality, captivating scientists and philosophers with its strange, counterintuitive principles: superposition, entanglement, uncertainty, and nonlocality.

Bell inequality, nonlocality and analyticity

M. Socolovsky, Autónoma México

The Bell and the Clauser-Horne-Shimony-Holt inequalities are shown to hold for both the cases of complex and real analytic nonlocality in the setting parameters of Einstein-Podolsky-Rosen-Bohm experiments for spin 1/2 particles and photons, in both the deterministic and stochastic cases. Therefore, the theoretical and experimental violation of the inequalities by quantum mechanics excludes all hidden variables theories with that kind of nonlocality. In particular, real analyticity leads to negative definite correlations, in contradiction with quantum mechanics.The Bell and the Clauser-Horne-Shimony-Holt inequalities are shown to hold for both the cases of complex and real analytic nonlocality in the setting parameters of Einstein-Podolsky-Rosen-Bohm experiments for spin 1/2 particles and photons, in both the deterministic and stochastic cases.
