πŸ”— Arcosanti

πŸ”— United States πŸ”— Architecture πŸ”— Urban studies and planning πŸ”— United States/Arizona

Arcosanti is a projected experimental town with a molten bronze bell casting business in Yavapai County, central Arizona, 70Β mi (110Β km) north of Phoenix, at an elevation of 3,732 feet (1,130 meters). Its arcology concept was posited by the Italian-American architect, Paolo Soleri (1919–2013). He began construction in 1970, to demonstrate how urban conditions could be improved while minimizing the destructive impact on the earth. He taught and influenced generations of architects and urban designers who studied and worked with him there to build the proposed "town".

πŸ”— Shatranj, the predecessor of modern chess

πŸ”— Chess πŸ”— India

Shatranj (Arabic: Ψ΄Ψ·Ψ±Ω†Ψ¬β€Ž; Persian: Ψ΄ΨͺΨ±Ω†Ϊ―β€Ž; from Middle Persian chatrang) is an old form of chess, as played in the Sasanian Empire. Its origins are in the Indian game of chaturaαΉ…ga. Modern chess gradually developed from this game, as it was introduced to the western world via contacts in Muslim Andalusia (modern Spain) and in Sicily in the 10th century.

πŸ”— Padonkaffsky jargon

πŸ”— Russia πŸ”— Russia/mass media in Russia πŸ”— Internet culture πŸ”— Russia/language and literature of Russia

Padonkaffsky jargon (Russian: язык ΠΏΠ°Π΄ΠΎΠ½ΠΊΠ°Ρ„Ρ„, yazyk padonkaff) or Olbanian (олбанский, olbanskiy) is a cant language developed by a subculture of Runet called padonki (Russian: ΠΏΠ°Π΄ΠΎΠ½ΠΊΠΈ). It started as an Internet slang language originally used in the Russian Internet community. It is comparable to the English-based Leet. Padonkaffsky jargon became so popular that the former President of Russia Dmitry Medvedev jokingly suggested that Olbanian be taught in schools.

πŸ”— ThyssenKrupp Express Walkway

πŸ”— Technology

A moving walkway, also known as an autowalk, moving sidewalk, moving pavement, people-mover, travolator, or travelator, is a slow-moving conveyor mechanism that transports people across a horizontal or inclined plane over a short to medium distance. Moving walkways can be used by standing or walking on them. They are often installed in pairs, one for each direction.

Oliver Heaviside FRS (; 18 May 1850 – 3 February 1925) was an English self-taught electrical engineer, mathematician, and physicist who adapted complex numbers to the study of electrical circuits, invented mathematical techniques for the solution of differential equations (equivalent to Laplace transforms), reformulated Maxwell's field equations in terms of electric and magnetic forces and energy flux, and independently co-formulated vector analysis. Although at odds with the scientific establishment for most of his life, Heaviside changed the face of telecommunications, mathematics, and science.

πŸ”— Interplanetary Transport Network

πŸ”— Spaceflight πŸ”— Physics πŸ”— Systems πŸ”— Systems/Dynamical systems

The Interplanetary Transport Network (ITN) is a collection of gravitationally determined pathways through the Solar System that require very little energy for an object to follow. The ITN makes particular use of Lagrange points as locations where trajectories through space are redirected using little or no energy. These points have the peculiar property of allowing objects to orbit around them, despite lacking an object to orbit. While it would use little energy, transport along the network would take a long time.
