    en.wikipedia.org/wiki/Bull_Gamma_3

    The Gamma 3 was an early electronic vacuum-tube computer.It was designed by Compagnie des Machines Bull in Paris, France and released in 1952.. Originally designed as an electronic accelerator for electromechanical tabulating machines, similar to the IBM 604, it was gradually enhanced with new features and evolved into a first-generation stored program computer (Gamma AET, 1955, then ET, 1957).

    en.wikipedia.org/wiki/Hyundai_Gamma_engine

    The Hyundai Gamma engine was introduced in 2006 to replace the existing Hyundai Alpha engine. [1] There are 1.4 L and 1.6 L versions of this engine. The Gamma II can apparently run in Atkinson cycle (leaving intake open longer for more complete burn but less displacement) under low loads for additional fuel economy with the ability to shift to Otto cycle on demand under high loads or for extra ...

    en.wikipedia.org/wiki/Titanium_aluminide

    Titanium aluminide (chemical formula TiAl), commonly gamma titanium, is an intermetallic chemical compound. It is lightweight and resistant to oxidation [1] and heat, but has low ductility. The density of γ-TiAl is about 4.0 g/cm 3. It finds use in several applications including aircraft, jet engines, sporting equipment and automobiles.
