Glengarry Fine Cheesemaking in Lancaster (Eastern Ontario) also produces Quark. Also available in Canada is the very similar "Dry Curd Cottage Cheese"
Quark In 1977, the bottom quark was observed by a team at Fermilab led by Leon Lederman. This was a strong indicator of the top quark's existence: without the top quark, the bottom quark would have been without a partner. However, it was not until 1995 that the top quark was finally observed, also by the CDF and DØ teams at Fermilab. It had a mass much larger than had been previously expected, almost as large as that of a gold atom. For some time, Gell-Mann was undecided on an actual spelling for the term he intended to coin, until he
