J.S. Bach - Crab Canon on a Möbius Strip

Religion Religious activities around the world Many religions may have organized behaviors, clergy, a definition of what constitutes adherence or membership, holy places, and scriptures. The practice of a religion may include rituals, sermons, commemoration or veneration (of a deity, gods or goddesses), sacrifices, festivals, feasts, trance, initiations, funerary services, matrimonial services, meditation, prayer, music, art, dance, public service or other aspects of human culture. Religions may also contain mythology.[2] Etymology Religion (from O.Fr. religion "religious community," from L. religionem (nom. religio) "respect for what is sacred, reverence for the gods,"[11] "obligation, the bond between man and the gods"[12]) is derived from the Latin religiō, the ultimate origins of which are obscure.

Juan Downey - J.S. Bach (1986) 1986, 28:25 min, color, sound Resonating with a melancholy poetry, J.S. Bach is a subjective essay that merges a reflection on identity and the creative process with a lyrical documentary on the life of Johann Sebastian Bach. Philosophy Philosophy is the study of general and fundamental problems, such as those connected with reality, existence, knowledge, values, reason, mind, and language.[1][2] Philosophy is distinguished from other ways of addressing such problems by its critical, generally systematic approach and its reliance on rational argument.[3] In more casual speech, by extension, "philosophy" can refer to "the most basic beliefs, concepts, and attitudes of an individual or group".[4] The word "philosophy" comes from the Ancient Greek φιλοσοφία (philosophia), which literally means "love of wisdom".[5][6][7] The introduction of the terms "philosopher" and "philosophy" has been ascribed to the Greek thinker Pythagoras.[8] Areas of inquiry

The Beauty of Degraded Art: Why We Like Scratchy Vinyl, Grainy Film, Wobbly VHS & Other Analog-Media Imperfection "Whatever you find weird, ugly, or nasty about a medium will surely become its signature," writes Brian Eno in his published diary A Year with Swollen Appendices. "CD distortion, the jitteriness of digital video, the crap sound of 8-bit — all these will be cherished as soon as they can be avoided." Eno wrote that in 1995, when digital audio and video were still cutting-edge enough to look, sound, and feel not quite right yet. But when DVD players hit the market not long thereafter, making it possible to watch movies in flawless digital clarity, few consumers with the means hesitated to make the switch from VHS. Could any of them have imagined that we'd one day look back on those chunky tapes and their wobbly, muddy images with fondness? Or as Eno puts it, we want to hear "the sound of failure."

Collegare i punti: disegno isometrico e piani codificati - Attività Summary Students learn about isometric drawings and practice sketching on triangle-dot paper the shapes they make using multiple simple cubes. They also learn how to use coded plans to envision objects and draw them on triangle-dot paper. A PowerPoint® presentation, worksheet and triangle-dot (isometric) paper printout are provided. This activity is part of a multi-activity series towards improving spatial visualization skills.

Classical music Montage of some great classical music composers. From left to right: Top row: Antonio Vivaldi, Johann Sebastian Bach, George Frideric Handel, Wolfgang Amadeus Mozart, Ludwig van Beethoven; second row: Gioachino Rossini, Felix Mendelssohn, Frédéric Chopin, Richard Wagner, Giuseppe Verdi; third row: Johann Strauss II, Johannes Brahms, Georges Bizet, Pyotr Ilyich Tchaikovsky, Antonín Dvořák; bottom row: Edvard Grieg, Edward Elgar, Sergei Rachmaninoff, George Gershwin, Aram Khachaturian The term "classical music" did not appear until the early 19th century, in an attempt to distinctly canonize the period from Johann Sebastian Bach to Beethoven as a golden age.[7] The earliest reference to "classical music" recorded by the Oxford English Dictionary is from about 1836.[1][8] Characteristics[edit] Literature[edit]

Math Fair – natbanting.com History In late May 2015, one of my Grade 9 students had the idea to take some of our favourite classroom tasks to elementary school students. Two weeks later, the class was working alongside approximately 70 elementary school students (and future high school colleagues) at mathematical stations in the school’s small gym. The response from the school community was so positive, that the fair became a staple in the building.

3 Acts - Pop Box Design - Embrace the Drawing Board Ever wonder why companies make the decisions that they do? My wife and I drink more pop than I am willing to admit, and one thing I noticed while at the store is that the twelve packs of Coke and Pepsi do not have the same design. Let's look at them (warning I do not know if this works in the States). Nature by Numbers – ETÉREA Artists and architects have used since ancient times many geometrical and mathematical properties: we could take some examples simply by observing the refined use of the proportions by architects from Ancient Egypt, Greece and Rome or other Renaissance artists like Michelangelo, Da Vinci or Raphael. But what is more surprising for me is that many of these properties and mathematical developments are also present in nature. We could find countless cases, but I wanted to refer only three of them on this short animation: The Fibonacci Series and Spiral / The Golden and Angle Ratios / The Delaunay Triangulation and Voronoi Tessellations.

Gödel, Escher, Bach Gödel, Escher, Bach: An Eternal Golden Braid (pronounced [ˈɡøːdəl ˈɛʃɐ ˈbax]), 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.

Gödel's incompleteness theorems Gödel's incompleteness theorems are two theorems of mathematical logic that establish inherent limitations of all but the most trivial axiomatic systems capable of doing arithmetic. The theorems, proven by Kurt Gödel in 1931, are important both in mathematical logic and in the philosophy of mathematics. The two results are widely, but not universally, interpreted as showing that Hilbert's program to find a complete and consistent set of axioms for all mathematics is impossible, giving a negative answer to Hilbert's second problem. The first incompleteness theorem states that no consistent system of axioms whose theorems can be listed by an "effective procedure" (i.e., any sort of algorithm) is capable of proving all truths about the relations of the natural numbers (arithmetic). For any such system, there will always be statements about the natural numbers that are true, but that are unprovable within the system.
