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
Bilinear form of the bilinear form "B" and is independent of the antisymmetric part. In this case there is a one-to-one correspondence between the symmetric part of the bilinear form and the quadratic form, and it makes sense to speak of the symmetric bilinear form associated with a quadratic form. When and , this correspondence between quadratic forms and symmetric bilinear forms breaks down. Definition: A bilinear form is called reflexive if implies for all v, w in "V". Definition: Let be a reflexive bilinear form. v, w in "V" are orthogonal with respect to "B" if . A bilinear form "B"
