A free software Asteroids-like video game played on a vector monitor. Vector-based devices, such as the vector CRT and the pen plotter, directly control a drawing mechanism to produce geometric shapes. Since vector display devices can define a line by dealing with just two points (that is, the coordinates of each end of the line), the device ...
GNU Image Manipulation Program, commonly known by its acronym GIMP (/ ɡ ɪ m p / GHIMP), is a free and open-source raster graphics editor [4] used for image manipulation (retouching) and image editing, free-form drawing, transcoding between different image file formats, and more specialized tasks. It is extensible by means of plugins, and ...
Understanding wealth in America can be eye-opening. You might assume that becoming a millionaire is something only a few achieve, but recent data shows that the average household net worth in the ...
Haidinger's brush, more commonly known as Haidinger's brushes is an image produced by the eye, an entoptic phenomenon, first described by Austrian physicist Wilhelm Karl von Haidinger in 1844. Haidinger saw it when he looked through various minerals that polarized light. [1] [2] Many people are able to perceive polarization of light. [3]
Kansas City Chiefs defensive tackle Chris Jones has offered to cover $1.5 million worth of chicken wings in order to free the former food service employee who stole them. The 68-year-old Liddell ...
Total Recall is a 1990 American science-fiction action film directed by Paul Verhoeven (pictured). Based on a 1966 short story by Philip K. Dick, the film stars Arnold Schwarzenegger, Rachel Ticotin, Sharon Stone, Ronny Cox, and Michael Ironside. It tells the story of Douglas Quaid (Schwarzenegger) and the shadow organization that tries to ...
In vector calculus, a conservative vector field is a vector field that is the gradient of some function. [ 1] A conservative vector field has the property that its line integral is path independent; the choice of path between two points does not change the value of the line integral. Path independence of the line integral is equivalent to the ...
In mathematics, a free module is a module that has a basis, that is, a generating set consisting of linearly independent elements. Every vector space is a free module, [ 1] but, if the ring of the coefficients is not a division ring (not a field in the commutative case), then there exist non-free modules. Given any set S and ring R, there is a ...
