Solar Pond

A solar pond is a man-made pool of saltwater that not only absorbs heat from sunlight, but is able to store it for use in heating or power generation. In a freshwater pond, sun-warmed water rises to the top, loses its heat to the atmosphere, becomes denser, and sinks again. In a solar pond, however, a layer of highly salty water remains trapped at the bottom by its own density, even as it is warmed by sunlight—thereby storing heat. Typically, how hot is the bottom of a solar pond? Discuss

International Women's Day

This day commemorating women is one of the most widely observed holidays of recent origin. It has its roots in the March 8, 1857, revolt of women in New York City, protesting conditions in the textile and garment industries, although it wasn’t proclaimed a holiday until 1910. In the former USSR, women received honors for distinguished service in industry, aviation, military service, and other fields. In the United Kingdom and the United States, International Women’s Day is marked by special exhibitions, films, and more, in praise of women. Discuss

The Kit-Cat Club

The Kit-Cat Club was an association of some of the best young writers and most prominent Whig politicians in early 18th-century London. Among the roughly four dozen members were figures such as Sir Robert Walpole, William Congreve, and Joseph Addison, in addition to a number of dukes. They first met in the tavern of Christopher Catling, whose mutton pies were called kit-cats. In its time, the club was well known for drinking toasts to notable women of the day. Who were some of those honored? Discuss
