We look at soil chemistry—for example, how much nitrogen or magnesium there is in the soil in one spot—and we compare it with the chemistry of the soil a short distance away.
Marie Curie, now at the highest point of her fame and, from 1922, a member of the Academy of Medicine, researched the chemistry of radioactive substances and their medical applications.
Study on quantitative structure-property relationship of organics would be helpful in researching for equeous solubility and octanal-water partition coefficients of organics.
Thus, for example, if a student posts a libelous message to our Usenet server and we never learn of it, the student alone will be liable if the message results in a lawsuit.
