Advanced Usage
- Etymology Note: The term originates from quantum physics, where a "quantum leap" describes an electron's instantaneous jump from one discrete energy level to another without passing through the space in between. In general usage, this scientific origin reinforces the idea of a sudden, discontinuous, and fundamental change.
