quantum physics
Quantum physics, translated as 'física cuántica' in Spanish, is a branch of physics that explains the nature and behavior of matter and energy at the quantum (the smallest discrete magnitude or parcel of energy). This specific theory is crucial to the understanding and development of modern physics and technology including semiconductors in our computers, atomic energy, and energy production & utilization. It also underpins the physics of photosynthesis, chemical reactions, and the mechanism of thermal conductivity in many materials. In essence, it is the physics that explains how everything works at the most fundamental levels of the universe.
