Ecology

Ecology (from Greek: οἶκος, "house", or "environment"; -λογία, "study of") is the scientific analysis and study of interactions among organisms and their environment. It is an interdisciplinary field that includes biology, geography and Earth science. Ecology includes the study of interactions organisms have with each other, other organisms, and with abiotic components of their environment. Topics of interest to ecologists include the diversity, distribution, amount (biomass), and number (population) of particular organisms, as well as cooperation and competition between organisms, both within and among ecosystems. Ecosystems are composed of dynamically interacting parts including organisms, the communities they make up, and the non-living components of their environment. Ecosystem processes, such as primary production, pedogenesis, nutrient cycling, and various niche construction activities, regulate the flux of energy and matter through an environment. These processes are sustained by organisms with specific life history traits, and the variety of organisms is called biodiversity. Biodiversity, which refers to the varieties of species, genes, and ecosystems, enhances certain ecosystem services.

Eco (video game)

Eco is a wire-frame 3D evolution life simulation game developed by Denton Designs for the Amiga and Atari ST. It was released in 1988 and published by Ocean Software.

The player initially uses mouse or joystick to control an insect, which must avoid predators, find some food, and then find another insect of the same species and mate with it. The player can then unlock one of several "genes", altering the value of which changes their creature. Some changes are only cosmetic and leave the creature in the same species; others can, for instance, make the initial insect a new species with wings and capable of flight. After unlocking multiple genes the player can become a fast dog-like quadruped, a bird, a scorpion or a humanoid. The game does not end until the player starves, is killed by another creature, or deliberately "evolves" into a plant.

Sphere

A sphere (from Greek σφαῖρα — sphaira, "globe, ball") is a perfectly round geometrical object in three-dimensional space that is the surface of a completely round ball, (viz., analogous to a circular object in two dimensions). Like a circle, which geometrically is a two-dimensional object, a sphere is defined mathematically as the set of points that are all at the same distance r from a given point, but in three-dimensional space. This distance r is the radius of the ball, and the given point is the center of the mathematical ball. The longest straight line through the ball, connecting two points of the sphere, passes through the center and its length is thus twice the radius; it is a diameter of the ball.

While outside mathematics the terms "sphere" and "ball" are sometimes used interchangeably, in mathematics a distinction is made between the sphere (a two-dimensional closed surface embedded in three-dimensional Euclidean space) and the ball (a three-dimensional shape that includes the sphere as well as everything inside the sphere). The ball and the sphere share the same radius, diameter, and center.

Spheres (instrumental)

"Spheres" is a classical digital-only single by Mike Oldfield from his album Music of the Spheres released on 3 March 2008 (see 2008 in music).

Demo version

The track "Spheres" is an early demo from the conception of Music of the Spheres and thus has no input from others, such as Karl Jenkins. It contains parts of the tracks "Harbinger" and "Shabda" from the album. The track is largely recorded using synthesized instruments, which were not used in the final album in favour of a full orchestra.

Charts

At the week ending 9 March 2008, "Spheres" was #1 on the 7digital Track Chart.

Spheres (Pestilence album)

Spheres is the fourth album by the Dutch death metal band Pestilence, released in 1993. It was their final album before a 14-year hiatus from 1994 to 2008. On this album, the band experimented with a more progressive sound, utilizing guitar synthesizers as well as some jazz influences.
