Andrés Segovia y J.S. Bach

Varios vídeos y una lista de Spotify. Me gusta sobre todo ésta:

Segovia’s “mere name,” writes Joseph Stevenson, “was enough to sell out houses worldwide.” A prodigy whose technique was “superior to that which was being taught at the time,” Segovia made his debut at the age of 15. Just a few years later, he played Madrid, the Paris Conservatory, and Barcelona, then, in 1919 made a “wildly successful” tour of South America. When he returned, the composer Albert Roussel wrote a piece specifically for him, which he performed in Paris, “the first of many works,” Stevenson writes, “written for him by distinguished composers…. There were classical guitarists before him, and distinguished ones even when he appeared, but it was not an instrument that was regarded as a serious vehicle for classical music. Segovia personally changed that.”

Balablok

Un corto divertido.

Director, animator, and puppeteer Bretislav Pojar explores human fallibility though simple paper cutout shapes in Balablok (1972). A masterful piece of wordless storytelling, the stop motion short film won the Cannes Film Festival’s Palme d’Or du court métrage in 1973. From the National Film Board of Canada: Here is an animated replay of the human…

Notes on a Triangle

Qué chulo:

From the National Film Board of Canada and director René Jodoin, this is Notes on a Triangle (1966), a ballet of three hundred geometric transformations, animated into divisions, alignments, and patterns. Waltz music by Maurice Blackburn. Per Enriching Mathematics, «Imagine replacing the triangle with a kite, or a rhombus, or an arrowhead, or…»

Descárgate un país

El país en cuestión es Suecia, y desde hace unos días te lo puedes descargar en forma de mapa para Minecraft:

Full Sweden as virtual and playable world in Minecraft! It becomes a reality when the National Land Survey releases a landscape model to the popular computer game. The model is based on the maps and elevation data that is released as open data in 2016.

Possibility to build a world of their own somewhere in Sweden will thus be available to all – provided you have the license to the game itself. The game and the construction is simplified by virtue of including roads and railways. Additionally, you can locate and navigate to the desired location in the country through a built-in feature for teleportation.

Eso sí, estamos hablando de un país entero, por lo que está disponible para descargar por trozos. Buscas la parte que te interesa y listo. Yo me he descargado Estocolmo. Por otra parte, si eres valiente, puedes descargártelo entero, pero ya te advierten que eso ocupará 114GB una vez descomprimido.

Y por tener, hasta tienen trailer:

Caníbales en los mapas del siglo XVI

cannibalmap01

While cannibalism is not an unknown practice, especially in times of famine, it was never as widespread as shown in these 16th-century atlases. Maps, going back to antiquity, have always been about more than just charting geography; they affirm structures of power, including the control of unseen land, and act as an imperialist tool for reinforcing stereotypes and encouraging fear of the unfamiliar.

Transfinitos

Un curioso comentario sobre el infinito (y la matemática en general) en los cómics de Marvel (con una breve incursión en DC). La idea es que un universo de ese tipo contiene varios seres omniscientes y omnipotentes que sin embargo están claramente ordenados siguiendo una jerarquía donde algunos de esos seres son más poderosos que otros.

Se centra, claro está, en que el infinito es difícil de entender y los autores se explican muy mal o directamente no han entendido.

Now, the obvious explanation of all of this is that the writers at Marvel recalled hearing something about different sizes of infinity in a philosophy course at some point during their alcohol-soaked college years, but couldn’t remember the details (or misremembered them, etc.), and so they just made some shit up. Fine and dandy. But the really interesting question is this: How should we interpret passages such as the one above, where cosmic beings seem to be sincerely explaining the nature of the multiverse in terms of transfinite cardinal numbers, but where they get the mathematics horribly wrong?

Origen: False Mathematics and Comic-book Fiction « The Hooded Utilitarian

El problema que plantea se da de forma similar en Bajo la misma estrella, donde la protagonista en cierto momento afirma que el infinito de números reales entre 0 y 2 es el doble de grande que el infinito entre 0 y 1.

Lo interesante de este último caso es que por lo visto el autor de la novela, John Green, es consciente de que no es así, que la cardinalidad es la misma. Es un poco triste, sin embargo, que prefiriese introducir un error en lugar de intentar buscar la forma de hacer que la protagonista dijese lo correcto. ¿No hubiese quedado mejor?
