IN: The holiday is sometimes called Dia de los Muertos in Anglophone countries, a back-translation of its original name, Dia de Muertos. It is particularly celebrated in Mexico where the day is a public holiday. Prior to Spanish colonization in the 16th century, the celebration took place at the beginning of summer. Gradually, it was associated with October 31, November 1, and November 2 to coincide with the Western Christianity triduum of Allhallowtide: All Saints' Eve, All Saints' Day, and All Souls' Day. Traditions connected with the holiday include building private altars called ofrendas, honoring the deceased using calaveras, aztec marigolds, and the favorite foods and beverages of the departed, and visiting graves with these as gifts. Visitors also leave possessions of the deceased at the graves.

IN: The cougar (Puma concolor), also commonly known as the puma, mountain lion, panther or catamount, is a large felid of the subfamily Felinae native to the Americas. Its range, from the Canadian Yukon to the southern Andes of South America, is the widest of any large wild terrestrial mammal in the Western Hemisphere. An adaptable, generalist species, the cougar is found in most American habitat types. It is the biggest cat in North America, and the second-heaviest cat in the New World after the jaguar. Secretive and largely solitary by nature, the cougar is properly considered both nocturnal and crepuscular, although daytime sightings do occur. The cougar is more closely related to smaller felines, including the domestic cat (subfamily Felinae), than to any species of subfamily Pantherinae, of which only the jaguar is native to the Americas.

IN: In chemistry, pH (/piet/) is a logarithmic scale used to specify the acidity or basicity of an aqueous solution. It is approximately the negative of the base 10 logarithm of the molar concentration, measured in units of moles per liter, of hydrogen ions. More precisely it is the negative of the base 10 logarithm of the activity of the hydrogen ion. Solutions with a pH less than 7 are acidic and solutions with a pH greater than 7 are basic. Pure water is neutral, at pH 7 (25 C), being neither an acid nor a base. Contrary to popular belief, the pH value can be less than 0 or greater than 14 for very strong acids and bases respectively.

IN: The notation for castling, in both the descriptive and the algebraic systems, is 0-0 with the kingside rook and 0-0-0 with the queenside rook; in PGN, O-O and O-O-O are used instead. Castling on the kingside is sometimes called castling short and castling on the queenside is called castling long -- the difference based on whether the rook moves a short distance (two squares) or a long distance (three squares) (Hooper & Whyld 1992).
