Critters (block cellular automaton)

Critters is a reversible block cellular automaton with similar dynamics to Conway's Game of Life, first described by Tommaso Toffoli and Norman Margolus in 1987.

Definition

Critters is defined on a two-dimensional infinite grid of cells, which may be identified with the integer lattice. As in Conway's Game of Life, at any point in time each cell may be in one of two states: alive or dead. The Critters rule is a block cellular automaton using the Margolus neighborhood. This means that, at each step, the cells of the automaton are partitioned into 2 × 2 blocks and each block is updated independently of the other blocks. The center of a block at one time step becomes the corner of four blocks at the next time step, and vice versa; in this way, the four cells in each block belong to four different 2 × 2 blocks of the previous partition.

The transition function for Critters counts the number of live cells in a block, and if this number is exactly two it leaves the block unchanged. If the number of live cells is zero, one, or four, the transition function flips the state of every cell in the block. And finally, if the number of live cells is exactly three, the transition flips every state and then rotates the whole block by 180°. Because the function that combines these operations is invertible, the automaton defined by these rules is a reversible cellular automaton.

Critters (comics)

Critters was a funny animal anthology comic book published by Fantagraphics Books from 1985 to 1990 under the editorship of Kim Thompson.

Prior to Furrlough and Genus, this was the longest running funny animal anthology comic book series. The title lasted for 50 issues. Furthermore, it served as the flagship title of Fantagraphics' line of funny animal series in the 1980s.

The last 12 issues were switched to revolving features of issue-long stories, rather than the anthology format. Declining sales, due in part to the 1980s black-and-white comics market overload (many titles of which were funny-animal comics aiming for the Teenage Mutant Ninja Turtles market) led to this title's cancellation.

Alan Moore released a single "March of the Sinister Ducks" as a flexi disc in the comic issue 23.

Sunlight

Sunlight is a portion of the electromagnetic radiation given off by the Sun, in particular infrared, visible, and ultraviolet light. On Earth, sunlight is filtered through Earth's atmosphere, and is obvious as daylight when the Sun is above the horizon. When the direct solar radiation is not blocked by clouds, it is experienced as sunshine, a combination of bright light and radiant heat. When it is blocked by the clouds or reflects off other objects, it is experienced as diffused light. The World Meteorological Organization uses the term "sunshine duration" to mean the cumulative time during which an area receives direct irradiance from the Sun of at least 120 watts per square meter.

The ultraviolet radiation in sunlight has both positive and negative health effects, as it is both a principal source of vitamin D₃ and a mutagen.

Summary

Researchers may record sunlight using a sunshine recorder, pyranometer, or pyrheliometer.

Sunlight takes about 8.3 minutes to reach Earth from the surface of the Sun. A photon starting at the centre of the Sun and changing direction every time it encounters a charged particle would take between 10,000 and 170,000 years to get to the surface.

Sunshine (The Archies album)

Sunshine is the fourth studio album released by The Archies, a fictional bubblegum pop band of The Archie Show and the Archie Comics universe. The album includes 12 tracks and was issued on Kirshner Records. It was produced by Jeff Barry. The album features the single "Sunshine". The song peaked at number 57 on the Billboard Hot 100. The album peaked at number 137 on the Billboard Top LPs chart.

Sunshine (Jonathan Edwards song)

"Sunshine" is a country folk song from 1971 by Jonathan Edwards, released as the first single from his debut album Jonathan Edwards. The single reached Billboard #4 and earned a gold record.

"Sunshine" was not originally planned for release, but when an engineer accidentally erased the master of a track called "Please Find Me" near the end of sessions for the album, "Sunshine" was used to fill the hole.

The song was released as a single and first gained popularity on Boston radio, then nationwide, hitting #4 on the Billboard Hot 100 chart on January 15, 1972 and earning a gold record. Here's Edwards' take on its success: "It was just at the time of the Vietnam War and Nixon. It was looking bad out there. That song meant a lot to a lot of people during that time--especially me."
