Astroscan Telescope

Julia

Nos han traído un Telescopio Astroscan!

TheAstroscanwas a wide-field 4⅛” clear-inch (105mm) diameterreflecting telescope, originally produced by theEdmund Scientific Corporation, that was for sale from 1976 to 2013.

The Astroscan had aNewtonian reflectorlayout with a 4⅛” clear-inch (105mm) diameterf/4.2aluminized and overcoatedborosilicate glassparabolicprimary mirrorwith afocal lengthof 17½ inches (445mm).[1]The telescope’ssecondary mirrorwas mounted on a flat optical window at the front of the tube. Edmund designerNorman Sperlingand optical engineer Mike Simmons came up with the basic design and Peter Bressler Design Associates did the detailed work on this simple introductory telescope.[2][3]Rather than using a more traditionalequatorialoraltazimuth mountthe Astroscan features a spherical housing around the primary reflector which sat in a castaluminumcradle. The design was durable and allowed for simple operation…

WTF! App and the WordPress logo

I never noticed before that the “W” on this video is the same as the on in the @WordPress logo

WTF! es un proyecto audiovisual realizado con técnicas de animación tradicional (stop motion).

Produjimos un logotipo corpóreo de plomo. Por medio de una matriz en cera se extrajo un molde para obtención de la pieza en metal. Los módulos debían tener una cierta altura para poder jugar con la perspectiva y los volúmenes de ésta. El resultado fue un logotipo de 5 kg.

El proceso de animación se dividió en fases diferenciadas. Por un lado  queríamos conseguir un movimiento muy fluido de la cámara, similar a un travelling real. Para ello se utilizó un travelling de mesa y construimos unas guías en círculo a modo de vía, con una separación entre marca y marca de milímetros. Para cada disparo de foto desplazamos el carro una línea.

Por otro lado había que coreografiar la deformación del logo. Para cada paso trasladamos el módulo de metal a otro sitio para golpearlo con una maza. Después se colocaba exactamente en la misma posición que en el fotograma anterior.

Además de la cámara móvil, se emplearon otras cuatro más para ir registrando diferentes puntos de vista.

Polybius (Urban Legend)

Polybius is a fictitious arcade game, the subject of an urban legend that emerged in early 2000.[1][2] It has served as inspiration for several free and commercial games by the same name.

The legend describes the game as part of a government-run crowdsourced psychology experiment based in Portland, Oregon, during 1981. Gameplay supposedly produced intense psychoactive and addictive effects in the player. These few publicly staged arcade machines were said to have been visited periodically by men in black for the purpose of data-mining the machines and analyzing these effects. Eventually, all of these Polybius arcade machines allegedly disappeared from the arcade market.

The company behind the games was named Sinneschloschen (Meaning Sense Lose. Not a real german word, though).

Stochastic

Stochastic refers to a randomly determined process.[1] The word first appeared in English to describe a mathematical object called a stochastic process, but now in mathematics the terms stochastic process and random process are considered interchangeable.[2][3][4][5][6] The word, with its current definition meaning random, came from German, but it originally came from Greek στόχος (stókhos), meaning ‘aim, guess’.[1]

The term stochastic is used in many different fields, particularly where stochastic or random processes are used to represent systems or phenomena that seem to change in a random way. The term is used in the physical sciences such as biology,[7] chemistry,[8] ecology,[9] neuroscience,[10] and physics[11] as well as technology and engineering fields such as image processingsignal processing,[12] information theory,[13] computer science,[14] (including the field of artificial intelligence), cryptography[15] and telecommunications.[16] It is also used in finance, due to seemingly random changes in financial markets[17][18][19] as well as in medicine, linguistics, music, media, colour theory, botany, manufacturing, and geomorphology.

I was reading about this in the context of Ray Tracing but I have heard it being mentioned in the context of neural networks and, to some extent, it was applied to decipher Enigma.
