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
Sesquilinear form basis of , a sesquilinear form is represented by a matrix , by the column vector , and by the column vector : The components of are given by . A complex Hermitian form (also called a symmetric sesquilinear form), is a sesquilinear form such that The standard Hermitian form on is given (again, using the "physics" convention of linearity in the second and conjugate linearity in the first variable) by More generally, the inner product on any complex Hilbert space is a Hermitian form. A vector space with a Hermitian form is called a Hermitian space. The matrix representation
