Fúzí

Fúzió, in Hungarian often written fúzió, is the act or process of joining two or more distinct entities to form a single, more complex whole. The term comes from the Latin fusio, and in many languages the concept is used across science, industry, and culture to describe merging or blending that preserves features of the parts while creating new properties.

In science, fusion refers most often to nuclear fusion, the process by which light atomic nuclei combine to form heavier nuclei, releasing large amounts of energy. This is the source of the sun’s energy and a major field of energy research on Earth. Practical fusion aims to produce sustained energy output with controlled reactions, using devices such as tokamaks or inertial confinement facilities. Notable efforts include the international ITER project in France and the National Ignition Facility in the United States. Fusion should not be confused with chemical fusion used in metallurgy or phase transitions, where substances simply melt or join at high temperatures.

In business, fusion or merger refers to combining two or more companies into a single legal entity. The goal is often to realize synergies, expand markets, or reduce costs. Mergers are subject to regulatory review to prevent anti-competitive effects.

Beyond science and industry, fusion describes cultural blends such as fusion cuisine—where elements from different culinary traditions are combined—and fusion music, which blends styles such as jazz with rock, funk, or world music. In information technology, data fusion means integrating data from multiple sensors to produce more accurate or comprehensive information than any single source.

Fúzió remains a broad concept, reflecting the general idea that disparate parts can combine to create something new while retaining some of their original characteristics.
