Medicine in ancient Rome mother's milk (or colostrum) is actually a rather effective treatment. Colostrum has been shown to prevent the growth of "Staphylococcus" bacteria, which are a known cause of several types of infection. Colostrum is about half as effective as some antibiotics prescribed to patients today. Colostrum is also effective against the bacterium chlamydia; this is the cause of a sexually transmitted disease and also can cause severe sight impairment, if not blindness. Thus, colostrum was a rather effective treatment in the ancient world – perhaps that is why it was viewed as a divine treatment. The interpretation of dreams was another
Quadratic form is also called a quadratic form. Two "n"-dimensional quadratic spaces and are isometric if there exists an invertible linear transformation (isometry) such that The isometry classes of "n"-dimensional quadratic spaces over "K" correspond to the equivalence classes of "n"-ary quadratic forms over "K". Let "R" be a commutative ring, "M" be an "R"-module and be an "R"-bilinear form. A mapping is the "associated quadratic form" of "b", and is the "polar form" of "Q". Alternatively, a quadratic form may be characterized as follows: Two elements "v" and "w" of "V" are called orthogonal if . The kernel of a bilinear
