parabolic
Significado: Having the form or properties of a parabola — a symmetrical open curve. In practical use, it describes reflectors, antennas, and trajectories that exploit the geometric properties of this shape.
Parabolic appears in physics, engineering, and telecommunications. Parabolic reflectors concentrate incoming waves (light, radio, sound) at a single focal point, making them essential in satellite dishes, telescopes, and solar collectors. In finance journalism, 'parabolic' describes a price chart that curves sharply upward — 'Bitcoin went parabolic.' In sport, a parabolic trajectory describes the arc of a kicked or thrown ball. The term has also entered informal usage to describe any dramatic, exponential rise.
