Sirius

Sirius (/ˈsɪriəs/) is the brightest star (in fact, a star system) in the Earth's night sky. With a visual apparent magnitude of −1.46, it is almost twice as bright as Canopus, the next brightest star. The name "Sirius" is derived from the Ancient Greek Σείριος (Seirios), meaning "glowing" or "scorcher". The system has the Bayer designation Alpha Canis Majoris (α CMa). What the naked eye perceives as a single star is actually a binary star system, consisting of a white main-sequence star of spectral type A1V, termed Sirius A, and a faint white dwarf companion of spectral type DA2, called Sirius B. The distance separating Sirius A from its companion varies between 8.2 and 31.5 AU.

Sirius appears bright because of both its intrinsic luminosity and its proximity to Earth. At a distance of 2.6 parsecs (8.6 ly), as determined by the Hipparcos astrometry satellite, the Sirius system is one of Earth's near neighbors. Sirius is gradually moving closer to the Solar System, so it will slightly increase in brightness over the next 60,000 years. After that time its distance will begin to increase and it will become fainter, but it will continue to be the brightest star in the Earth's sky for the next 210,000 years.

Thumbs signal

A thumbs-up or thumbs-down is a common hand gesture achieved by a closed fist held with the thumb extended upward or downward in approval or disapproval, respectively. These gestures have become metaphors in English: "The audience gave the movie the thumbs-up" means that the audience approved of the movie, regardless of whether the gesture was actually made.

Origins

The source of the gesture is obscure, but a number of origins have been proposed.

Opposable thumbs

Carleton S. Coon, having observed Barbary apes in Gibraltar using the gesture, hypothesised in the anthropological classic The Story of Man that it is a mutual celebration of having opposable thumbs. Critics have suggested, however, that the apes may be simply imitating humans.

Ancient Rome

The Latin phrase pollice verso is used in the context of gladiatorial combat for a hand gesture used by Ancient Roman crowds to pass judgment on a defeated gladiator. However, the precise type of gesture described by the phrase pollice verso and its meaning are unclear in the historical and literary record.

Agar.io

Agar.io is a massively multiplayer action game created by Matheus Valadares. Players control a cell in a map representing a petri dish; the goal is to gain as much mass as possible by swallowing smaller cells without being swallowed by bigger ones. The name Agar.io comes from the substance agar, used to culture bacteria.

The game was released to positive critical reception. Critics particularly praised its simplicity, competition, and mechanics, while criticism targeted its repetitive gameplay. A downloadable Steam version was announced on 3 May 2015, and the mobile version of Agar.io for iOS and Android was released on 8 July 2015 by Miniclip.

Gameplay

The objective of Agar.io is to grow a cell by swallowing both randomly generated pellets, which slightly increase a cell's mass, and smaller cells without being swallowed by larger cells. It can be played in a deathmatch (free-for-all) or between teams. The goal of the game is to obtain the largest cell; players restart when all of their cells are swallowed. Players can change their cell's appearance with predefined words, phrases, symbols or skins. The more mass a cell has, the slower it will move. Cells gradually lose mass over time.

The Young Turks

The Young Turks (TYT) is an online American liberal/progressive political and social commentary program hosted by Cenk Uygur and Ana Kasparian; the show has an associated network of online shows and is owned by a company of the same name (The Young Turks LLC). TYT was founded in 2002 by Uygur as a talkshow on Sirius Satellite Radio.

The Young Turks claims to be "the world's largest online news show"; YouTube video views for the TYT Network stood at a total of 2 billion as of July 2014. The show offers internet-only video content via their YouTube channel, which in April 2012 averaged 750,000 views a day, and by November 2014 over 1,400,000 views a day. The Young Turks also have a network of other affiliated shows on separate YouTube channels, known collectively as the TYT Network.

From 2011 to 2013 a second show, called The Young Turks with Cenk Uygur aired on Current TV. After Current TV was acquired by Al Jazeera America, the TV show was discontinued.

History

The Young Turks as a show began when Cenk Uygur started a talk show similar to a public-access television cable-TV show he had done previously called The Young Turk. With the help of friend Ben Mankiewicz (with whom he had previously worked), his childhood friend Dave Koller, and Jill Pike, he began The Young Turks as a radio show in 2002 on Sirius Satellite Radio. The show's name derives from the English-language phrase "Young Turk", meaning a reformist or rebellious member of an institution, movement, or political party.
