Light is a science fiction novel by M. John Harrison published in 2002. It received the James Tiptree, Jr. Award and a BSFA nomination in 2002, and was shortlisted for the Arthur C. Clarke Award in 2003.

Overview

The book centres on the lives of three individuals — the physicist (and serial killer) Michael Kearney, on the verge of a breakthrough in theoretical physics sometime in 1999; Seria Mau Genlicher, the cybernetically-altered female pilot of a "K-ship", and the ex-space pilot and adventurer Ed Chianese. Seria Mau and Ed's stories take place in the year 2400 AD.

The lives of these three individuals are linked in many ways, though most tangibly by the presence of a mysterious creature called The Shrander, who appears in many guises to all three characters throughout the novel (with anagrammatic names of Sandra Shen and Dr. Haends). They are also linked by the Kefahuchi Tract, a space-time anomaly described as "a singularity without an event horizon", an object of awe and wonder that has been the ruin of many civilisations attempting to decode its mysteries.

A window is an opening in a wall, door, roof or vehicle that allows the passage of light and, if not closed or sealed, air and sound.

Modern windows are usually glazed or covered in some other transparent or translucent material. Windows are held in place by frames. Many glazed windows may be opened, to allow ventilation, or closed, to exclude inclement weather. Windows often have a latch or similar mechanism to lock the window shut.

Types include the eyebrow window, fixed windows, single-hung and double-hung sash windows, horizontal sliding sash windows, casement windows, awning windows, hopper windows, tilt and slide windows (often door-sized), tilt and turn windows, transom windows, sidelight windows, jalousie or louvered windows, clerestory windows, skylights, roof windows, roof lanterns, bay windows, oriel windows, thermal, or Diocletian, windows, picture windows, emergency exit windows, stained glass windows, French windows, and double- and triple paned windows.

The Romans were the first known to use glass for windows, a technology likely first produced in Roman Egypt, in Alexandria ca. 100 AD. Paper windows were economical and widely used in ancient China, Korea and Japan. In England, glass became common in the windows of ordinary homes only in the early 17th century whereas windows made up of panes of flattened animal horn were used as early as the 14th century. Modern-style floor-to-ceiling windows became possible only after the industrial plate glass making processes were perfected.

In theology, divine light (also called divine radiance or divine refulgence) is an aspect of divine presence, specifically an unknown and mysterious ability of God, angels, or human beings to express themselves communicatively through spiritual means, rather than through physical capacities.

Spirituality

The term light has been used in spirituality (vision, enlightenment, darshan, Tabor Light). Bible commentators such as Ritenbaugh see the presence of light as a metaphor of truth, good and evil, knowledge and ignorance. In the first Chapter of the Bible, Elohim is described as creating light by fiat and seeing the light to be good. In Hinduism, Diwali — the festival of lights — is a celebration of the victory of light over darkness. A mantra in Bṛhadāraṇyaka Upaniṣad(1.3.28) urges God to 'from darkness, lead us unto Light'.

Various local religious concepts exist:

In medicine, a pulse represents the tactile arterial palpation of the heartbeat by trained fingertips. The pulse may be palpated in any place that allows an artery to be compressed against a bone, such as at the neck (carotid artery), on the inside of the elbow (brachial artery), at the wrist (radial artery), at the groin (femoral artery), behind the knee (popliteal artery), near the ankle joint (posterior tibial artery), and on foot (dorsalis pedis artery). Pulse (or the count of arterial pulse per minute) is equivalent to measuring the heart rate. The heart rate can also be measured by listening to the heart beat directly (auscultation), traditionally using a stethoscope and counting it for a minute. The radial pulse is commonly measured using three fingers. This has a reason; the finger closest to the heart is used to occlude the pulse pressure, the Middle finger is used get a crude estimate of the blood pressure, and the finger most distal to the heart ( usually the ring finger) is used to nullify the effect of the ulnar pulse as the two arteries are connected via the palmar arches. The study of the pulse is known as sphygmology.

In physics, a pulse is a single disturbance that moves through a medium from one point to the next point.

Pulse Reflection

Consider a pulse moving through a medium - perhaps through a rope or a slinky. When the pulse reaches the end of that medium, what happens to it depends on whether the medium is fixed in space or free to move at its end. For example, if the pulse is moving through a rope and the end of the rope is held firmly by a person, then it is said that the pulse is approaching a fixed end. On the other hand, if the end of the rope is fixed to a stick such that it is free to move up or down along the stick when the pulse reaches its end, then it is said that the pulse is approaching a free end.

Free End

A pulse will reflect off a free end and return with the same direction of displacement that it had before reflection. That is, a pulse with an upward displacement will reflect off the end and return with an upward displacement.

This is illustrated by figures 1 and 2 that were obtained by the numerical integration of the wave equation.

Pulse, known in Japan as Kairo (回路), is a 2001 Japanese horror film directed by Kiyoshi Kurosawa. The film is based on his novel of the same name. The film was screened in the Un Certain Regard section at the 2001 Cannes Film Festival. The movie was well-received critically and has a cult following. An American remake, also titled Pulse, debuted in 2006 and spawned two sequels.

Plot

The plot centers on ghosts invading the world of the living via the Internet. It features two parallel story lines.

First Story

The first story involves a young woman named Kudo Michi (Kumiko Aso) who works at a plant sales company. She has recently moved to the city and her main friends are her three colleagues, Sasano Junko, Toshio Yabe and Taguchi. At the start of the film, it appears Taguchi has been missing for some days working on a computer disk. Michi goes to visit his apartment and finds him distracted and aloof; in the middle of their conversation, he casually makes a noose, leaves and hangs himself. Michi and her colleagues inspect the computer disk he left behind and discover it contains an image of Taguchi staring at his own computer monitor, which is displaying an image of Taguchi staring at his computer monitor, creating an endless series of images. In the other monitor on his desk, Michi and her friends discover a ghostly face staring out into Taguchi's room.
