Quark (dairy product) Quark (dairy product) Quark or quarg is a type of fresh dairy product made by warming soured milk until the desired amount of curdling is met, and then straining it. It can be classified as fresh acid-set cheese. Traditional quark can be made without rennet, but in modern dairies small quantities of rennet are typically added. It is soft, white and unaged, and usually has no salt added. It is traditional in the cuisines of German-speaking, Slavic and Scandinavian countries. Dictionaries sometimes translate it as curd cheese, cottage cheese, farmer cheese or junket. In Germany, quark and cottage cheese are
Top quark Top quark The top quark, also known as the t quark (symbol: t) or truth quark, is the most massive of all observed elementary particles. Like all quarks, the top quark is a fermion with spin , and experiences all four fundamental interactions: gravitation, electromagnetism, weak interactions, and strong interactions. It has an electric charge of + "e". It has a mass of 172.44 ± 0.13 (stat) ± 0.47 (syst), which is about the same mass as an atom of tungsten. The antiparticle of the top quark is the top antiquark (symbol: , sometimes called "antitop quark" or simply "antitop"),
