input: In 2008, the band announced that its core group of musicians would be parting ways, but Johnsson posted that he was in no way ending Therion. Johan Koleberg became the new drummer, and Nalle Pahlsson the bassist. The band did not tour that year, except for a single open-air festival show in Plock, Poland on 6 September.  On 10 May 2009, following the release of The Miskolc Experience, Therion announced Thomas Vikstrom as its new lead vocalist. The band worked on a new album, Sitra Ahra, which featured new guitarist Christian Vidal, and Snowy Shaw on vocals.  Sitra Ahra was released on 17 September 2010 The band toured South and Central America for 17 days, and European tour through November and December.  In March 2011, Gothic Kabbalah singer Katarina Lilja left the band for a second time to "re-join the boring civil world and not be a cool rock star anymore". Vikstrom's daughter, Linnea, provided supporting vocals for the band at the Bloodstock Open Air festival in 2011. Therion performed at Hellfest Summer Open Air, ProgPower USA, and the 2012 cruise liner based festival 70000 Tons of Metal. In a Bloodstock interview, Shaw mentioned that the band will work on new material at the end of the year. In September 2011, after four years of collaboration and session work, vocalist Lori Lewis joined Therion as a member. In this year also a board game called "011" was released; it features the band members and is based on the Sitra Ahra album.

input: Ptolemy's Almagest is the only surviving comprehensive ancient treatise on astronomy. Babylonian astronomers had developed arithmetical techniques for calculating astronomical phenomena; Greek astronomers such as Hipparchus had produced geometric models for calculating celestial motions. Ptolemy, however, claimed to have derived his geometrical models from selected astronomical observations by his predecessors spanning more than 800 years, though astronomers have for centuries suspected that his models' parameters were adopted independently of observations. Ptolemy presented his astronomical models in convenient tables, which could be used to compute the future or past position of the planets. The Almagest also contains a star catalogue, which is a version of a catalogue created by Hipparchus. Its list of forty-eight constellations is ancestral to the modern system of constellations, but unlike the modern system they did not cover the whole sky (only the sky Hipparchus could see). Across Europe, the Middle East and North Africa in the Medieval period, it was the authoritative text on astronomy, with its author becoming an almost mythical figure, called Ptolemy, King of Alexandria. The Almagest was preserved, like most of extant Classical Greek science, in Arabic manuscripts (hence its familiar name). Because of its reputation, it was widely sought and was translated twice into Latin in the 12th century, once in Sicily and again in Spain. Ptolemy's model, like those of his predecessors, was geocentric and was almost universally accepted until the appearance of simpler heliocentric models during the scientific revolution.  His Planetary Hypotheses went beyond the mathematical model of the Almagest to present a physical realization of the universe as a set of nested spheres, in which he used the epicycles of his planetary model to compute the dimensions of the universe. He estimated the Sun was at an average distance of 1,210 Earth radii, while the radius of the sphere of the fixed stars was 20,000 times the radius of the Earth.  Ptolemy presented a useful tool for astronomical calculations in his Handy Tables, which tabulated all the data needed to compute the positions of the Sun, Moon and planets, the rising and setting of the stars, and eclipses of the Sun and Moon. Ptolemy's Handy Tables provided the model for later astronomical tables or zijes. In the Phaseis (Risings of the Fixed Stars), Ptolemy gave a parapegma, a star calendar or almanac, based on the hands and disappearances of stars over the course of the solar year.

input: At a September 10, 2008, press conference, Paul announced his general support of four third-party candidates: Cynthia McKinney (Green Party); Bob Barr (Libertarian Party); Chuck Baldwin (Constitution Party); and Ralph Nader (independent). He said that each of them had pledged to adhere to a policy of balancing budgets, bringing the troops home, defending privacy and personal liberties, and investigating the Federal Reserve. Paul also said that under no circumstances would he be endorsing either of the two main parties' candidates (McCain - Republican Party, or Obama - Democratic Party) because there were no real differences between them, and because neither of them, if elected, would seek to make the fundamental changes in governance that were necessary. He urged instead that, rather than contribute to the "charade" that the two-party election system had become, the voters support the third-party candidates as a protest vote, to force change in the election process. Later that same day, Paul gave a televised interview with Nader saying much the same again.  Two weeks later, "shocked and disappointed" that Bob Barr (the Libertarian nominee) had pulled out of attending the press conference at the last minute and had admonished Paul for remaining neutral and failing to say which specific candidate Paul would vote for in the general election, Paul released a statement saying that he had decided to endorse Chuck Baldwin, the Constitution Party candidate, for president.  Paul withdrew from active campaigning in the last weeks of the primary election period. He received 42,426 votes, or 0.03% of the total cast, in the general election.
