Gödel, Escher, Bach

A must read for all who want to know about infinity … almost good enough to provide a foundation … but then it is just a carpet floating mid air as long as you don’t open your eyes … Gödel, Escher, Bach: An Eternal Golden Braid, also known as GEB, is a 1979 book by Douglas Hofstadter, described by his publishing company as “a metaphorical fugue on minds and machines in the spirit of Lewis Carroll”.[1] By exploring common themes in the lives and works of logician Kurt Gödel, artist M. C. Escher and composer Johann Sebastian Bach, GEB expounds concepts fundamental to mathematics, symmetry, and intelligence. Through illustration and analysis, the book discusses how self-reference and formal rules allow systems to acquire meaning despite being made of “meaningless” elements. It also discusses what it means to communicate, how knowledge can be represented and stored, the methods and limitations of symbolic representation, and even the fundamental notion of “meaning” itself. In response to confusion over the book’s theme, Hofstadter has emphasized that GEB is not about mathematics, art, and music but rather about how cognition and thinking emerge from well-hidden neurological mechanisms. In the book, he presents an analogy about how the individual neurons of the brain coordinate to create a unified sense of a coherent mind by comparing it to the social organization displayed in a colony of ants.[2][3]… >> Go to Source...

Scientists reveal drinking champagne could improve memory

… I knew it … something in me was saying the same … if I just could remember … och, another glass might help ! New research shows that drinking one to three glasses of champagne a week may counteract the memory loss associated with ageing, and could help delay the onset of degenerative brain disorders, such as dementia. Scientists at the University of Reading have shown that the phenolic compounds found in champagne can improve spatial memory, which is responsible for recording information about one’s environment, and storing the information for future navigation....

274,207,281 − 1

Largest known prime number As of January 2017, the largest known prime number is 274,207,281 − 1, a number with 22,338,618 digits. It was found in 2016 by the Great Internet Mersenne Prime Search (GIMPS). Plot of the number of digits in largest known prime by year, since the electronic computer. Note that the vertical scale is logarithmic. The red line is the exponential curve of best fit: y = exp(0.187394 t – 360.527), where t is in years. Euclid proved that there is no largest prime number, and many mathematicians and hobbyists continue to search for large prime numbers. Many of the largest known primes are Mersenne primes. As of January 2017, the six largest known primes are Mersenne primes, while the seventh is the largest known non-Mersenne prime.[1] The last 16 record primes were Mersenne primes.[2][3] The fast Fourier transform implementation of the Lucas–Lehmer primality test for Mersenne numbers is fast compared to other known primality tests for other kinds of numbers.

Voronoi Tessellation

In mathematics, a Voronoi diagram is a way of dividing space into a number of regions. A set of points (called seeds, sites, or generators) is specified beforehand and for each seed there will be a corresponding region consisting of all points closer to that seed than to any other. The regions are called Voronoi cells. It is dual to the Delaunay triangulation. It is named after Georgy Voronoy, and is also called a Voronoi tessellation, a Voronoi decomposition, a Voronoi partition, or a Dirichlet tessellation (after Peter Gustav Lejeune Dirichlet). Voronoi diagrams can be found in a large number of fields in science and technology, even in art, and they have found numerous practical and theoretical applications. >> Goto Source Follow the link below to see an animated Voronoi Tessellation … be the wandering point … Voronoi Tessellation The Voronoi tessellation shows the closest point on the plane for a given set of points.

John Venn and the Diagrams

Venn diagrams were introduced in 1880 by John Venn (1834–1923) in a paper entitled On the Diagrammatic and Mechanical Representation of Propositions and Reasonings in the “Philosophical Magazine and Journal of Science”, about the different ways to represent propositions by diagrams.[1] The use of these types of diagrams in formal logic, according to Ruskey and M. Weston, is “not an easy history to trace, but it is certain that the diagrams that are popularly associated with Venn, in fact, originated much earlier. They are rightly associated with Venn, however, because he comprehensively surveyed and formalized their usage, and was the first to generalize them”.[2] Venn himself did not use the term “Venn diagram” and referred to his invention as “Eulerian Circles.”[1] For example, in the opening sentence of his 1880 article Venn writes, “Schemes of diagrammatic representation have been so familiarly introduced into logical treatises during the last century or so, that many readers, even those who have made no professional study of logic, may be supposed to be acquainted with the general nature and object of such devices. Of these schemes one only, viz. that commonly called ‘Eulerian circles,’ has met with any general acceptance…”[3] The first to use the term “Venn diagram” was Clarence Irving Lewis in 1918, in his book “A Survey of Symbolic Logic”.[2] Venn diagrams are very similar to Euler diagrams, which were invented by Leonhard Euler (1708–1783) in the 18th century.[note 1] M. E. Baron has noted that Leibniz (1646–1716) in the 17th century produced similar diagrams before Euler, but much of it was unpublished. She also observes even earlier Euler-like diagrams by...

Kolumba

Extraordinary architectural building combining new and old and spirit and space … Definitely worth a visit when in cologne. Kolumba is the art museum of the Archdiocese of Cologne, originally founded in 1853. Since 2004, the museum has borne the name of its new location amidst the ruins of the late Gothic parish church of St Kolumba, thus providing a spiritual home to the collection. A triad of place, collection, and architecture, it allows the visitor to experience two millennia of western culture in a single building. Comprising art from late antiquity to the very present, the whole ensemble is imbued with a still reverberating sense of history – visibly intensified through its distinctive architecture. The modern building is a harmonious combination designed by Swiss architect Peter Zumthor (2007) to merge both the Gothic ruins of St Kolumba and Böhm’s chapel »Madonna in the Ruins« (1950) with the unique archaeological excavation site (1973-76). Kolumba has been aptly termed »a museum of contemplation in which there is an ongoing dialogue between past and present« (Sarah McFadden, Art in America). Kolumba is curated by Stefan Kraus, Ulrike Surmann, Marc Steinmann und Barbara von Flüe. >> Go to Source Here are a few pictures to give you an...

Sergei Vasilievich Rachmaninoff

Sergei Vasilievich Rachmaninoff (1 April 1873 – 28 March 1943) was a Russian-born composer, pianist, and conductor.[2] Rachmaninoff is widely considered one of the finest pianists of his day and, as a composer, one of the last great representatives of Romanticism in Russian classical music.[3] Early influences of Tchaikovsky, Rimsky-Korsakov, and other Russian composers gave way to a personal style notable for its song-like melodicism, expressiveness and his use of rich orchestral colors.[4] The piano is featured prominently in Rachmaninoff’s compositional output, and through his own skills as a performer he explored the expressive possibilities of the instrument. >> Go to Source...
