Lactose is a disaccharide sugar synthesized by galactose and glucose subunits and has the molecular formula C12H22O11. Lactose makes up around 2–8% of milk (by mass). The name comes from lac (gen. lactis), the Latin word for milk, plus the suffix -ose used to name sugars. The compound is a white, water-soluble, non-hygroscopic solid with a mildly sweet taste. It is used in the food industry.
Stout is a dark, top-fermented beer with a number of variations, including dry stout, oatmeal stout, milk stout, and imperial stout.

The Houtman Abrolhos is a chain of 122 islands and associated coral reefs, in the Indian Ocean off the west coast of Australia, about 80 km (50 mi) west of Geraldton, Western Australia. It is the southernmost true coral reef in the Indian Ocean, and one of the highest latitude reef systems in the world. It is one of the world's most important seabird breeding sites, and is the centre of Western Australia's largest single-species fishery, the western rock lobster fishery. It has a small seasonal population of fishermen, and a limited number of tourists are permitted for day trips, but most of the land area is off limits as conservation habitat. It is well known as the site of numerous shipwrecks, the most famous being the Dutch ships Batavia, which was wrecked in 1629, and Zeewijk, wrecked in 1727.
Cornelis de Houtman was a Dutch merchant seaman who commanded the first Dutch expedition to the East Indies. Although the voyage was difficult and yielded only a modest profit, Houtman showed that the Portuguese monopoly on the spice trade was vulnerable. A flurry of Dutch trading voyages followed, eventually leading to the displacement of the Portuguese and the establishment of a Dutch monopoly on spice trading in the East Indies.
Lactic acid fermentation is a metabolic process by which glucose or other six-carbon sugars are converted into cellular energy and the metabolite lactate, which is lactic acid in solution. It is an anaerobic fermentation reaction that occurs in some bacteria and animal cells, such as muscle cells.
Adémar de Chabannes was a French/Frankish monk, active as a composer, scribe, historian, poet, grammarian and literary forger. He was associated with the Abbey of Saint Martial, Limoges, where he was a central figure in the Saint Martial school, an important center of early medieval music. Much of his career was spent copying and transcribing earlier accounts of Frankish history; his major work was the Chronicon Aquitanicum et Francicum. He is well-known for forging a Vita, purportedly by Aurelian of Limoges, that indicated Saint Martial was one of the original apostles. Though he successfully convinced the local bishop and abbot of its authenticity, the traveling monk Benedict of Chiusa exposed his forgery and damaged Adémar's reputation.
Frederick de Houtman was a Dutch explorer, navigator, and colonial governor who sailed on the first Dutch expedition to the East Indies from 1595 until 1597, during which time he made observations of the southern celestial hemisphere and contributed to the creation of 12 new southern constellations.

The Cursor Mundi is an early 14th-century religious poem written in Northumbrian Middle English that presents an extensive retelling of the history of Christianity from the creation to the doomsday. The poem is long, composed of almost 30,000 lines, but shows considerable artistic skill. In spite of the immense mass of material with which it deals, it is well proportioned, and the narrative is lucid and easy.

The earliest known world maps date to classical antiquity, the oldest examples of the 6th to 5th centuries BCE still based on the flat Earth paradigm. World maps assuming a spherical Earth first appear in the Hellenistic period. The developments of Greek geography during this time, notably by Eratosthenes and Posidonius culminated in the Roman era, with Ptolemy's world map, which would remain authoritative throughout the Middle Ages.

The book commonly known as Blaeu Atlas of Scotland, the fifth volume of Theatrum Orbis Terrarum Sive Atlas Novus, is the first known atlas of Scotland and Ireland. It was compiled by Joan Blaeu, and contains 49 engraved maps and 154 pages of descriptive text written in Latin; it was first published in 1654.
