Bivector
In mathematics, a bivector or 2-vector is a quantity in exterior algebra or geometric algebra that extends the idea of scalars and vectors. If a scalar is considered an order zero quantity, and a vector is an order one quantity, then a bivector can be thought of as being of order two. Bivectors have applications in many areas of mathematics and physics. They are related to complex numbers in two dimensions and to both pseudovectors and quaternions in three dimensions. They can be used to generate rotations in any number of dimensions, and are a useful tool for classifying such rotations. They also are used in physics, tying together a number of otherwise unrelated quantities.
Space
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. Debates concerning the nature, essence and the mode of existence of space date back to antiquity; namely, to treatises like the "Timaeus" of Plato, or Socrates in his reflections on what the Greeks called "khôra" (i.e.
Four-dimensional space
A four-dimensional space or 4D space is a mathematical extension of the concept of three-dimensional or 3D space. Three-dimensional space is the simplest possible generalization of the observation that one only needs three numbers, called "dimensions", to describe the sizes or locations of objects in the everyday world. For example, the volume of a rectangular box is found by measuring its length (often labeled "x"), width ("y"), and depth ("z"). More than two millennia ago Greek philosophers explored in detail the many implications of this uniformity, culminating in Euclid's "Elements". However, it was not until recent times that some mathematicians generalized the concept of dimensions to include more than three.
Spacetime
In physics, spacetime is any mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. Spacetime diagrams are useful in visualizing and understanding relativistic effects such as how different observers perceive "where" and "when" events occur. Until the turn of the 20th century, the assumption had been that the three-dimensional geometry of the universe (its description in terms of locations, shapes, distances, and directions) was distinct from time (the measurement of when events occur within the universe). However, Albert Einstein's 1905 "special theory of relativity" postulated that the speed of light through empty space has one definite value—a constant—that is independent of the motion of the light source.
Dimension
In physics and mathematics, the dimension of a mathematical space (or object) is informally defined as the minimum number of coordinates needed to specify any point within it. Thus a line has a dimension of one because only one coordinate is needed to specify a point on itfor example, the point at 5 on a number line. A surface such as a plane or the surface of a cylinder or sphere has a dimension of two because two coordinates are needed to specify a point on itfor example, both a latitude and longitude are required to locate a point on the surface of a sphere. The inside of a cube, a cylinder or a sphere is three-dimensional because three coordinates are needed to locate a point within these spaces.
M-theory
M-theory is a theory in physics that unifies all consistent versions of superstring theory. The existence of such a theory was first conjectured by Edward Witten at a string theory conference at the University of Southern California in the spring of 1995. Witten's announcement initiated a flurry of research activity known as the second superstring revolution. Prior to Witten's announcement, string theorists had identified five versions of superstring theory. Although these theories appeared, at first, to be very different, work by several physicists showed that the theories were related in intricate and nontrivial ways.
List of Tenchi Muyo! characters
The following is a list of the major characters from the anime and manga series "Tenchi Muyo! Ryo-Ohki" and its spin-offs "Tenchi Muyo! GXP", "Tenchi Muyo! War on Geminar", "Tenchi Universe", "Tenchi in Tokyo", "Ai Tenchi Muyo! ", "", "Magical Project S", and "Magical Girl Pretty Sammy". Masaki Kajishima and Hiroki Hayashi, who both worked on the "Bubblegum Crisis" OAVs, cite the show as being the inspiration for "Tenchi Muyo! Ryo-Ohki". In an interview with AIC, Hayashi described "Bubblegum Crisis" as "a pretty gloomy anime. Serious fighting, complicated human relationships, and dark Mega Tokyo."
