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
Hasse invariant of a quadratic form Hasse invariant of a quadratic form In mathematics, the Hasse invariant (or Hasse–Witt invariant) of a quadratic form "Q" over a field "K" takes values in the Brauer group Br("K"). The name "Hasse–Witt" comes from Helmut Hasse and Ernst Witt. The quadratic form "Q" may be taken as a diagonal form Its invariant is then defined as the product of the classes in the Brauer group of all the quaternion algebras This is independent of the diagonal form chosen to compute it. It may also be viewed as the second Stiefel–Whitney class of "Q". The invariant may be computed for
