- Alhazen — The Latinized name of the great Persian-Arab scholar, physicist, mathematician, and astronomer Ḥasan Ibn al-Haytham (c. 965–1040), widely considered the father of modern optics and the experimental scientific method. His seminal work, 'Book of Optics', revolutionized the understanding of vision.
- Arago — The reference name of François Arago (1786–1853), a famous French physicist, astronomer, and politician, who made foundational contributions to optics, magnetism, and electromagnetism, demonstrating the wave nature of light. His name became a scientific eponym of major significance, assigned to a lunar crater, a Martian crater, an asteroid, a ring of Neptune, as well as multiple global academic institutions.
- Arsonval — A proper surname of French origin, made famous by the physicist and physician Jacques-Arsène d'Arsonval. In scientific terminology, the name is used as an eponym to designate the d'Arsonval galvanometer (a moving-coil device used to measure electric current) or the d'Arsonval current (high-frequency current historically used in electrotherapy).
- Astrophysicist — A scientist, researcher, or highly qualified specialist in the field of astrophysics; an expert who applies the methods, theories, and principles of fundamental physics to investigate the structure, dynamic behavior, life cycles, and radiation of celestial bodies. Their activity includes spectral analysis of light emitted by stars, modeling collisions between black holes, or interpreting global gravitational anomalies.
- Astrophysicist — A woman who works as an astrophysicist; a highly qualified female researcher or specialist in the field of astrophysics who applies physical laws and principles to study the chemical composition, internal structure, orbital dynamics, and evolution of celestial bodies. Her activity involves utilizing high-power spectrographs, interpreting gravitational anomalies around black holes, and developing computational mathematical models to explain the expansion of the universe.
- Auger — A proper noun of French origin, famous in science due to physicist Pierre Victor Auger (1899-1993), discoverer of the Auger effect (radiationless electron emission). In engineering and technical terms derived from English, it also designates a large drill, boring tool, or screw conveyor used for drilling holes or moving granular materials.
