Passage: Plucknett describes Bracton in this way: "Two generations after Ranulf de Glanvill we come to the flower and crown of English jurisprudence – Bracton." Bracton was born around 1210 in Devon and had a great deal of preferment in the Church. He either derived from Bratton Fleming or Bratton Clovelly. Both villages are in Devon. It was only after his death that the family name appears as Bracton; during his life, he was known as Bratton, or Bretton. This originally may have been Bradton, meaning "Broad Town". Bracton first appeared as a justice in 1245. From 1248 until his death in 1268 he was steadily employed as a justice of the assize in the southwestern counties, especially Somerset, Devon and Cornwall. He was a member of the coram rege, also called the coram ipso rege, later to become the King's Court. He retired from this in 1257, shortly before the meeting of the Mad Parliament in 1258 at Oxford. It is unknown whether his retirement was related to politics. His leaving coincided with the onset of the notorious Second Barons' War in 1264. At that time Bracton was ordered to restore to the Treasury the large store of plea rolls (case records from previous trials) that had been in his possession. He was also forced to surrender the large number of rolls from his predecessors Martin Pateshull and William Raleigh, also known as William de Raley. It cannot be determined whether he disgraced the King or the barons in this affair, but it is speculated that some kind of political intrigue was involved. The practical result was that his major work, De Legibus et Consuetudinibus Angliae ("The Laws and Customs of England"), was left unfinished. Even so, it exists in four large volumes today. He continued to follow the assizes in the southwest until 1267. In the last year of his life he filled another prominent role, as member of a commission of prelates, magnates and justices appointed to hear the complaints of the "disinherited" – those who had sided with Simon de Montfort, 6th Earl of Leicester.

Passage: Alecia Beth Moore (born September 8, 1979), known professionally as Pink (stylized as ), is an American singer and songwriter. She was originally a member of the girl group Choice. In 1995, LaFace Records saw potential in Pink and offered her a solo recording contract. Her R&B-influenced debut studio album Can't Take Me Home (2000) was certified double-platinum in the United States and spawned two Billboard Hot 100 top-ten songs: "There You Go" and "Most Girls". She gained further recognition with the collaborative single "Lady Marmalade" from the Moulin Rouge! soundtrack, which topped many charts worldwide. Refocusing her sound to pop rock with her second studio album Missundaztood (2001), the album sold more than 13 million copies worldwide and yielded the international number-one songs "Get the Party Started", "Don't Let Me Get Me", and "Just Like a Pill".

Passage: The natural satellites orbiting relatively close to the planet on prograde, uninclined circular orbits (regular satellites) are generally thought to have been formed out of the same collapsing region of the protoplanetary disk that created its primary. In contrast, irregular satellites (generally orbiting on distant, inclined, eccentric and/or retrograde orbits) are thought to be captured asteroids possibly further fragmented by collisions. Most of the major natural satellites of the Solar System have regular orbits, while most of the small natural satellites have irregular orbits. The Moon and possibly Charon are exceptions among large bodies in that they are thought to have originated by the collision of two large proto-planetary objects (see the giant impact hypothesis). The material that would have been placed in orbit around the central body is predicted to have reaccreted to form one or more orbiting natural satellites. As opposed to planetary-sized bodies, asteroid moons are thought to commonly form by this process. Triton is another exception; although large and in a close, circular orbit, its motion is retrograde and it is thought to be a captured dwarf planet.
