Output: History


Input: Consider Input: This man gives his name, along with that of Francis Sears, to a process in ultrasonic imaging for which the acoustic wavefronts act as optical gratings to diffract the light on either side of the central spot. The distance over which charge carriers in plasmas exclude electric fields via his namesake shielding is also known as his namesake length. With an assistant later famous in his own right for his rule for determining whether ring molecules would show aromatic properties, he developed a mathematical expression to explain characteristics of electrolytic solutions, the famous equation named for him and Erich Hckel. FTP name this man who also gives his name to the SI unit defined as about 3.3 x 10-30 Coulomb meters, which measures the molecular dipole moment.

Output: Science


Input: Consider Input: This element can be detected in a test that uses strips of paper sensitized with mercuric chloride placed in a bottle containing granulated zinc, water, and hydrochloric acid. Another test for this element precipitates metallic silver out of a silver nitrate solution after a compound containing this element is reacted with nascent hydrogen. Those tests, named respectively for Gutzeit and Marsh, are used to distinguish this element from antimony. Paul Erlich developed syphilis-treating drugs containing this element, such as atoxyl and Salvarsan. More modern drugs containing it include Mel B, which is used to treat trypanosomiasis, or sleeping sickness. People who were given it tended to have brick red-colored mucosa on the post-mortem.
