## Mathematical landscape

Mathematical landscape is a term that describes the objects one finds in higher dimensions. It is also used in connection with mathematician's attempts to find unifying principles in physics and mathematics. Some believe that the link between them is an as yet undiscovered symmetry that will be the same symmetry under which the laws of nature behave. A particular example of this is the Monstrous moonshine conjecture, which linked the Monster group with modular functions and string theory. Another example is the appearance of the largest exceptional lie group, E8, as the gauge group of heterotic superstring theory.

196883 dimensions: The Monster group is the largest sporadic simple group and this is the smallest number of dimensions it acts in. It is the largest finite sporadic group. The monster group is linked with continuous objects like the J-invariant and modular forms by the Monstrous moonshine conjecture. It is conjectured to be the symmetry group of the constraint polynomial in invariance mechanics.

## Post Ejaculatory Guilt Syndrome

Post Ejaculatory Guilt Syndrome, or PEGS, is a little known but widely experienced sexual dysfunction which lasts for approximately 5 minutes after the male orgasm.This can occur both after sexual intercourse and more commonly following masturbation. During this period the male in question will find himself completely unattracted to the person or subject matter concerned in the previous activity. The male may also experience emotions of disgust or dislike towards both themselves and any other people they interact with during the PEGS period.

The latin phrase post coitum omne animal triste est (after sexual intercourse every animal is sad) describes this phenomenon. It is usually attributed to Aristotle. The quote is sometimes appended with praeter mulierem gallumque meaning: except the woman and the rooster.

## Dominoes on a chessboard puzzle

The mutilated chessboard problem is a famous puzzle introduced by Martin Gardner in his Scientific American column Mathematical Games. The problem is as follows: Suppose a standard 8x8 chessboard has two opposite corners removed, leaving 62 squares. Is it possible to place 31 dominoes of size 2x1 so as to cover all of these squares?

Solution: The puzzle is impossible. Any way you would place a domino would cover one white square and one black square. A group of 31 dominoes would cover 31 white and 31 black squares of a chessboard, leaving one white and one black square uncovered. The directions had you remove opposite corner squares, and such squares are always either both black or both white.

## Cable spaghetti

Cable spaghetti (sometimes known as plastic spaghetti, rat's nest, or cable clutter) is a term used to describe the often undesirable large mass of cables behind or connecting electronic devices, both for computers and entertainment systems.
Cable spaghetti for the home user is caused by the growing number of interconnected devices used in entertainment and computer systems. Whereas a record player and cassette deck were likely the only two components found up to the 1980s, today's systems can have an amplifier (or several if a preamplifier and power amplifier are used, and yet more for a passive subwoofer, a Tactile transducer or alternative transducer), television, CD player, SA-CD player, Laser Disc player, RF demodulator, VCR, DVD player, Blu-Ray disc or HD-DVD player, personal video recorder, cable or satellite tuner, video game console, and computer all connected in the same system. Cable clutter can even cause problems with audio and visual quality due to electromagnetic interference with other cables.

Dead-eye syndrome is a condition in computer generated films where the human characters appear artificial and creates a doll-like feeling to the characters, sometimes projecting there is no humanity in their eyes. This problem typically arises with computer generated characters made using motion capture technology. Since so much of human expressivity is determined by eye and eyelid movement, and since motion capture is unable to capture such subtle gradations, computer characters' eyes seem fixed and dilated, giving the feeling that the characters, though in motion, are dead.

Though it was not the first film to use motion capture technology, The Polar Express is generally regarded as the first film where the dead-eye syndrome was most noticeable and most distracting.

## A Million Penguins

A Million Penguins is a collabrotive effort to write a novel. The web site through which the novel is being written uses a wiki for the authors to add their submissions. Due to the overwhelming number of edits, over 100 every hour, Penguin has had to impose "reading windows" whereby they freeze the novel so that the more serious editors can read over what has been changed and thus get their bearings on where the story is going.
The novel soon became largely incoherent as many contributors strived to develop their own independent characters and story lines. In an attempt to control the chaos, several different versions of the novel were created. These include a choose your own adventure version, and a 'banana' version. The latter being formed when the editors grew tired of removing the recurring multitude of banana references.

Many collabrotive efforts are dedicated to writing software, scientific research, or amassing knowledge. Examples of these efforts are open source software, http://en.wikipedia.org/wiki/SETI%40Home, and Wikipedia. A Million Pengiuns is different in that the goal is one of art as opposed to science. Although Penguin put a lot of effort into advertising the wiki-novel, it quickly became a target for vandalism, which has led many of its early contributors to quit the project.
