Retrograde inversion, often referred to in the context of astronomy and planetary motion, describes the phenomenon when a planet appears to move backward (or retrograde motion) in its orbit as observed from Earth. This can happen when Earth, on its faster orbit, overtakes another planet that is slower in its orbit around the Sun. In the case of "inversion," the term is not commonly used specifically to describe retrograde motion.

A Cooper pair is a fundamental concept in the theory of superconductivity, which describes the pairing of two electrons (or other fermions) at very low temperatures. Named after the physicist Leon Cooper, who introduced the idea in 1956, Cooper pairs are essential for the Bardeen-Cooper-Schrieffer (BCS) theory of superconductivity. In a normal conductor, electrons experience repulsive interactions due to their negative charge.

Heusler compounds are a class of intermetallic materials that showcase unique magnetic, electronic, and mechanical properties.
