Digging

Digging is the process of using some implement such as claws, hands, or tools, to remove material from a solid surface, usually soil or sand on the surface of the Earth. Digging is actually the combination of two processes, the first being the breaking or cutting of the surface, and the second being the removal and relocation of the material found there. In a simple digging situation, this may be accomplished in a single motion, with the digging implement being used to break the surface and immediately fling the material away from the hole or other structure being dug.

Many kinds of animals engage in digging, either as part of burrowing behavior or to search for food or water under the surface of the ground. Historically, humans have engaged in digging for both of these reasons, and for a variety of additional reasons, such as engaging in agriculture and gardening, searching for minerals, metals, and other raw materials such as during mining and quarrying, preparing for construction, creating fortifications and irrigation, and also excavations in archaeology, searching for fossils and rocks in palaeontology and geology and burial of the dead.

Dig (I Mother Earth album)

Dig is the debut album by the Canadian alternative rock band I Mother Earth, released by Capitol and EMI on August 10, 1993. The album was certified Gold in Canada in its initial run, and stands at platinum today. It also won a Juno Award in 1994 for Best Hard Rock Album.

The album was noted for its metallic sound, balanced with psychedelic-style lyrics and instrumentals, and further backed by Latin percussion. The latter two were often brought into play during lengthy jam sessions.

Collective Soul (2009 album)

Collective Soul, also known as Rabbit to differentiate it from the band's 1995 album of the same name, is the eighth studio album by American rock band Collective Soul. It was released on August 25, 2009.

Background

Rabbit is Collective Soul's first release with a parent label since the group started its own independent El Music Group label in 2004. It also effectively marks their return to Atlantic Records, as that label purchased Roadrunner in 2006.

Rabbit includes two songs ("You" and "Understanding") that were written by all members in the band, a first for Collective Soul. According to the singer, guitarist and keyboard player Ed Roland: "I think it's the confidence that the other guys have gotten in their music skills and the songwriting and also, for lack of a better term, me letting go of my ego a little bit..."

Sim (album)

Sim is the third album by Brazilian singer-songwriter Vanessa da Mata, released on May 28, 2007 by Sony BMG. It was partially recorded at Kingston, Jamaica with musicians Sly & Robbie. It spawned the hit single "Boa Sorte/Good Luck", a duet with Ben Harper, which peaked at number one in both Brazil and Portugal, and was the most played song in Brazilian radio stations in the year of 2008. The second single, "Amado", also became a number-one hit in Brazil and the 15th most played song in the same year.

Sim (pencil game)

The game of Sim is played by two players on a board consisting of six dots ('vertices'). Each dot is connected to every other dot by a line ('edge').

Two players take turns coloring any uncolored lines. One player colors in one color, and the other colors in another color, with each player trying to avoid the creation of a triangle made solely of their color (only triangles with the dots as corners count; intersections of lines are not relevant); the player who completes such a triangle loses immediately.

Ramsey theory can also be used to show that no game of Sim can end in a tie. Specifically, since the Ramsey number R(3,3)=6, any two-coloring of the complete graph on 6 vertices (K₆) must contain a monochromatic triangle, and therefore is not a tied position. This will also apply to any super-graph of K₆. For another proof that there must eventually be a triangle of either color, see the Theorem on friends and strangers.

Computer search has verified that the second player can win Sim with perfect play, but finding a perfect strategy that humans can easily memorize is an open problem.
