Why Are We Obsessed with "Understanding" Quantum Mechanics?

TL;DR

This paper discusses the common perception of a lack of understanding of quantum mechanics, arguing that the real issue lies in the ontological interpretations and the metaphysical questions, rather than the predictive power of the theory.

Contribution

The paper challenges the notion that quantum mechanics is poorly understood, emphasizing the importance of embracing its fundamental quantum nature over classical metaphysical views.

Findings

Most physicists accept Copenhagen interpretation for practical purposes

The measurement problem reflects deeper ontological questions

True understanding requires embracing quantum reality, not classical assumptions

Abstract

Richard Feynman famously declared, "I think that I can safely say that nobody really understands quantum mechanics." Sean Carroll lamented the persistence of this sentiment in a recent opinion piece entitled, "Even Physicists Don't Understand Quantum Mechanics. Worse, they don't seem to want to understand it." Quantum mechanics is arguably the greatest achievement of modern science and by and large we absolutely understand quantum theory. Rather, the "understanding" to which these two statements evidently refer concerns the ontological status of theoretical constructs. For example, "Do quantum wave functions accurately depict physical reality?" The quantum measurement problems represents a collection of such queries and the conundrums to which they lead. Most physicists are content with foregoing such metaphysical issues, falling back on Bohr's Copenhagen interpretation, and then get on with the business of doing physics. I suspect that Carroll would criticize these physicists as being too dismissive of the wonderful mysteries of quantum mechanics by relegating its role to that of an algorithm for making predictions. Quite to the contrary, I maintain that those who still pursue a resolution to the measurement problem are burdened with a classical view of reality and fail to truly embrace the fundamental quantum aspects of nature.
