Leipäjuusto Leipäjuusto Leipäjuusto (bread cheese) or juustoleipä, which is also known in the United States as Finnish squeaky cheese, is a fresh cheese traditionally made from cow's beestings, rich milk from a cow that has recently calved. Reindeer or even goat milk can also be used. Commercially available versions are typically made from cow's milk, and they lack some of the colour and flavour because of this. The cheese originally comes from Southern Ostrobothnia, Northern Finland, and Kainuu. The milk is curdled and set to form a round disk from two to three centimeters thick. After this, leipäjuusto is baked, grilled,
Genus of a quadratic form Genus of a quadratic form In mathematics, the genus is a classification of quadratic forms and lattices over the ring of integers. An integral quadratic form is a quadratic form on Z, or equivalently a free Z-module of finite rank. Two such forms are in the same "genus" if they are equivalent over the local rings Z for each prime "p" and also equivalent over R. Equivalent forms are in the same genus, but the converse does not hold. For example, "x" + 82"y" and 2"x" + 41"y" are in the same genus but not equivalent over Z. Forms in
