History

Occlusion by this astronomical body of Saggitarius Tr-180 suggests that the rate of sublimation from its surface has doubled. That sublimation may have helped to create evaporite deposits such as the Akupara and Rem maculae, which cover a surface of beta-hexagonal ice surrounding the Plain of Abatus. Its changing albedo is believed to couple with gravitational diapirism to produce the cavi of its unique terrane of Bubeme. Perhaps the most interesting surface features occur in its equatorial region, which contains fault-block mountain ranges bounded by the Ho and Lo sulci, indicating a tectonic past, and the geyser plumes Hili and Mahilani, which contribute to its thin atmosphere. FTP, name this moon of Neptune best known for its cryovolcanic eruptions and its retrograde orbit.
Science

Induction coils with spark gaps were the first devices to suggest its existence. When the receiving coil in an 1887 experiment was enclosed in a dark case, the observed spark was always smaller. The aforementioned work by Hertz was followed by contributions in the area from Thomson and Lenard. Lenard found that it was independent of the ultraviolet lights intensity, but it took until the article On a Heuristic Point of View about the Creation and Conversion of Light for the concept to be widely diffused. For 10 points, the work function is associated with this effect, whose discovery won the 1905 Nobel Prize for Physics for Albert Einstein.
