Sand
Sand is a naturally occurring granular material composed of finely divided rock and mineral particles. It is defined by size, being finer than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e. a soil containing more than 85% sand-sized particles (by mass).
The composition of sand varies, depending on the local rock sources and conditions, but the most common constituent of sand in inland continental settings and non-tropical coastal settings is silica (silicon dioxide, or SiO2), usually in the form of quartz. The second most common type of sand is calcium carbonate, for example aragonite, which has mostly been created, over the past half billion years, by various forms of life, like coral and shellfish. It is, for example, the primary form of sand apparent in areas where reefs have dominated the ecosystem for millions of years like the Caribbean.
Composition
In terms of particle size as used by geologists, sand particles range in diameter from 0.0625 mm (or 1⁄16 mm) to 2 mm. An individual particle in this range size is termed a sand grain. Sand grains are between gravel (with particles ranging from 2 mm up to 64 mm) and silt (particles smaller than 0.0625 mm down to 0.004 mm). The size specification between sand and gravel has remained constant for more than a century, but particle diameters as small as 0.02 mm were considered sand under the Albert Atterberg standard in use during the early 20th century. A 1953 engineering standard published by the American Association of State Highway and Transportation Officials set the minimum sand size at 0.074 mm. A 1938 specification of the United States Department of Agriculture was 0.05 mm. Sand feels gritty when rubbed between the fingers (silt, by comparison, feels like flour).
Sand!

Sandō
A sandō (参道, visiting path) in Japanese architecture is the road approaching either a Shinto shrine or a Buddhist temple. Its point of origin is usually straddled in the first case by a Shinto torii, in the second by a Buddhist sanmon, gates which mark the beginning of the shrine's or temple territory. The word dō (道) can refer both to a path or road, and to the path of one's life's efforts. See, Karatedo. c.f. Taoism 道 There can also be stone lanterns and other decorations at any point along its course.
A sandō can be called a front sandō (表参道, omote-sandō), if it is the main entrance, or a rear sandō (裏参道, ura-sandō) if it is a secondary point of entrance, especially to the rear; side sandō (脇参道, waki-sandō) are also sometimes found. The famous Omotesandō district in Tokyo, for example, takes its name from the nearby main access path to Meiji Shrine where an ura-sandō also used to exist.

Daniel Rosenfeld
Daniel Rosenfeld (born May 9, 1989) is a German musician and sound engineer best known as the composer and sound designer for the computer game Minecraft. His music is generally published under the name C418 (pronounced "see-four-eighteen").
Rosenfeld was born and grew up in East Germany after reunification, and the economic realities of the region limited his resources to learn audio composition . He says he learned on early versions of Schism Tracker and Ableton Live in the early 2000s, which were both rudimentary tools at the time. Learning under such restrictions turned out to help the young composer when he began collaborating with Minecraft creator Markus "Notch" Persson. The sound engine in the game was not very powerful, so Rosenfeld had to be creative in his approach to sound effects and music.
As a freelance artist, Rosenfeld was not on staff at Mojang, the game company behind Minecraft, which was sold to Microsoft in 2014. Rosenfeld says he still owns the rights to all the music in the game, having released two albums featuring songs from the soundtrack. The first soundtrack, Minecraft - Volume Alpha, was released on March 4, 2011. The video game blog Kotaku selected the music of Minecraft as one of the best video game soundtracks of 2011. On November 9, 2013, Rosenfeld released the second official soundtrack, titled Minecraft - Volume Beta, which includes the music that was added in later versions of the game.Minecraft - Volume Alpha found its first release in physical format on Ghostly International in 2015.
