Gin Gin Gin is liquor which derives its predominant flavour from juniper berries ("Juniperus communis"). Gin is one of the broadest categories of spirits, all of various origins, styles, and flavour profiles that revolve around juniper as a common ingredient. From its earliest origins in the Middle Ages, the drink has evolved from a herbal medicine to an object of commerce in the spirits industry. Gin was developed based on the older Dutch liquor, jenever, and became popular in Great Britain (particularly in London) when William of Orange became King William III of England.

Flavour (particle physics) description of the flavour symmetry is described by a chiral group . If all quarks had non-zero but equal masses, then this chiral symmetry is broken to the "vector symmetry" of the "diagonal flavour group" , which applies the same transformation to both helicities of the quarks. This reduction of symmetry is a form of "explicit symmetry breaking". The amount of explicit symmetry breaking is controlled by the current quark masses in QCD. Even if quarks are massless, chiral flavour symmetry can be spontaneously broken if the vacuum of the theory contains a chiral condensate (as it does in low-energy
