Quantum theory is a fundamental pillar of modern physics education in both Brazil and the United States. In Brazil, it is taught extensively in physics programs at universities like USP and UFRJ. The term is used formally in academic settings and is often referenced metaphorically in popular culture to describe breakthrough innovations or sudden changes, though this usage can be imprecise scientifically.
