AI Summary

Physicists at Heinrich Heine University Düsseldorf and the German Aerospace Center examined a core aspect of quantum mechanics. In a paper in Physical Review Letters, they argue that the theory can be formulated using real numbers instead of the traditionally required imaginary numbers. The study focuses on the mathematical foundations that describe atomic and subatomic particles. The authors suggest that real‑number formulations may offer an alternative framework for quantum theory. The work builds on the early 20th‑century development of quantum mechanics by pioneers such as Planck, Bohr, Heisenberg, and Schrödinger.
