The X-Seed 4000 is a visionary skyscraper for what would be, if it was built, the tallest building in the world. The idea was initially created and developed by Peter Neville. Its proposed 4-kilometre (2.5 mi) height, 6-kilometre-wide (3.7 mi) sea-base, and 800-floor capacity could accommodate 500,000 to 1,000,000 inhabitants. This structure would be composed of over 3,000,000 tons of pure steel.

It was designed for Tokyo, Japan by the Taisei Corporation in 1995 as a futuristic environment combining ultra-modern living and interaction with nature. Methods of transportation within the X-seed would most likely include MagLev trains.

The X-Seed 4000 "is never meant to be built," says Georges Binder, managing director of Buildings & Data, a firm which compiles data banks on buildings worldwide. "The purpose of the plan was to earn some recognition for the firm, and it worked."

Unlike conventional skyscrapers, to remain habitable the (X-Seed 4000) would be forced to actively protect its occupants from considerable internal air pressure and external air pressure gradations and weather fluctuations that its massive elevation would cause. Its design calls for the use of solar power to maintain internal environmental conditions. As the proposed site for the structure is located in the Pacific Ring of Fire, the most active volcano range in the world, the X-Seed 4000 would be subject to earthquakes and tsunamis.

A sea-based location and a Mount Fuji shape are some of this building's other major design features—the real Mount Fuji is land-based and is 3,776 metres (12,388 ft) high so is 224 metres (735 ft) shorter than the X-Seed 4000.

The X-Seed 4000 is projected to be twice the height of the Shimizu Mega-City Pyramid at 2,004 metres (6,575 ft). The Shimizu Mega-City Pyramid (proposed in 2007, also planned for Tokyo, Japan) faces most of the same problems as the X-Seed. Other projects that may be in the top five man made structures are the Ultima Tower 3,218 metres (10,558 ft) in San Francisco, Dubai City Tower 2,400 metres (7,900 ft) and the Bionic Tower 1,228 metres (4,029 ft) in either Hong Kong or Shanghai.

The Boirault machine (French: Appareil Boirault), was an early French experimental landship, designed in 1914 and built in early 1915. It has been considered as "another interesting ancestor of the tank", and described as a "rhomboid-shaped skeleton tank without armour, with single overhead track". Ultimately, the machine was deemed impractical and was nicknamed Diplodocus militaris. It preceded the design and development of the English Little Willie tank by six months.

🔗 Physics 🔗 Systems 🔗 Systems/Dynamical systems

In mathematics and physics, the Poincaré recurrence theorem states that certain dynamical systems will, after a sufficiently long but finite time, return to a state arbitrarily close to (for continuous state systems), or exactly the same as (for discrete state systems), their initial state.

The Poincaré recurrence time is the length of time elapsed until the recurrence. This time may vary greatly depending on the exact initial state and required degree of closeness. The result applies to isolated mechanical systems subject to some constraints, e.g., all particles must be bound to a finite volume. The theorem is commonly discussed in the context of ergodic theory, dynamical systems and statistical mechanics. Systems to which the Poincaré recurrence theorem applies are called conservative systems.

The theorem is named after Henri Poincaré, who discussed it in 1890 and proved by Constantin Carathéodory using measure theory in 1919.

🔗 Visual arts

The Voyage of Life is a series of four paintings created by Thomas Cole in 1842, representing an allegory of the four stages of human life. The paintings, Childhood, Youth, Manhood, and Old Age, depict a voyager who travels in a boat on a river through the mid-19th-century American wilderness. In each painting the voyager rides the boat on the River of Life accompanied by a guardian angel. The landscape, each reflecting one of the four seasons of the year, plays a major role in conveying the story. With each installment the boat's direction of travel is reversed from the previous picture. In childhood, the infant glides from a dark cave into a rich, green landscape. As a youth, the boy takes control of the boat and aims for a shining castle in the sky. In manhood, the adult relies on prayer and religious faith to sustain him through rough waters and a threatening landscape. Finally, the man becomes old and the angel guides him to heaven across the waters of eternity.

An antimacassar is a small cloth placed over the backs or arms of chairs, or the head or cushions of a sofa, to prevent soiling of the permanent fabric underneath. The name also refers to the cloth flap 'collar' on a sailor's shirt or top, used to keep macassar oil off the uniform.

Macassar oil was an unguent for the hair commonly used by men in the early 19th century, and reputed to have been manufactured from ingredients purchased in the port of Makassar in the Dutch East Indies. The poet Byron called it "thine incomparable oil, Macassar". The fashion for oiled hair became so widespread in the Victorian and the Edwardian period that housewives began to cover the arms and backs of their chairs with washable cloths to prevent the fabric coverings from being soiled. Around 1850, these started to be known as antimacassars. They were also installed in theatres, from 1865.

They came to have elaborate patterns, often in matching sets for the various items of parlour furniture; they were either made at home using a variety of techniques such as crochet or tatting, or purchased. The original antimacassars were usually made of stiff white crochet-work, but in the third quarter of the 19th century they became simpler and softer, usually fabric embroidered with a simple pattern in wool or silk.

By the beginning of the 20th century, antimacassars had become so associated in people's minds with the Victorian period that the word briefly became a figurative term for it. For example, antimacassars are suggestive of old-fashioned, Victorian-era women in Rebecca West's novel The Return of the Soldier.

Antimacassars are also used on the seat headrests of commercial passenger transport vehicles, such as trains, buses and, especially, aircraft, to prevent the transmission of hair dressings and conditions between passengers, simplify maintenance, and extend the life of fabrics.

This is a list of interface bit rates, is a measure of information transfer rates, or digital bandwidth capacity, at which digital interfaces in a computer or network can communicate over various kinds of buses and channels. The distinction can be arbitrary between a computer bus, often closer in space, and larger telecommunications networks. Many device interfaces or protocols (e.g., SATA, USB, SAS, PCIe) are used both inside many-device boxes, such as a PC, and one-device-boxes, such as a hard drive enclosure. Accordingly, this page lists both the internal ribbon and external communications cable standards together in one sortable table.

🔗 Technology 🔗 Transport

A paternoster (, , or ) or paternoster lift is a passenger elevator which consists of a chain of open compartments (each usually designed for two persons) that move slowly in a loop up and down inside a building without stopping. Passengers can step on or off at any floor they like. The same technique is also used for filing cabinets to store large amounts of (paper) documents or for small spare parts. The much smaller belt manlift which consists of an endless belt with steps and rungs but no compartments is also sometimes called a paternoster.

The name paternoster ("Our Father", the first two words of the Lord's Prayer in Latin) was originally applied to the device because the elevator is in the form of a loop and is thus similar to rosary beads used as an aid in reciting prayers.

The construction of new paternosters was stopped in the mid-1970s out of concern for safety, but public sentiment has kept many of the remaining examples open. By far most remaining paternosters are in Europe, with 230 examples in Germany, and 68 in the Czech Republic. Only three have been identified outside Europe: one in Malaysia, one in Sri Lanka, and another in Peru.

The tall poppy syndrome is the cultural phenomenon of jealous people holding back or directly attacking those who are perceived to be better than the norm, "cutting down the tall poppy". It describes a draw towards mediocrity.

Commonly in Australia and New Zealand, "Cutting down the tall poppy" is used to describe those who think too highly of themselves and it is seen by some as self-deprecating and by others as promoting modesty and egalitarianism.

Piyamaradu (also spelled Piyama-Radu, Piyama Radu, Piyamaradus, Piyamaraduš) was a warlike personage whose name figures prominently in the Hittite archives of the middle and late 13th century BC in western Anatolia. His history is of particular interest because it appears to intertwine with that of the Trojan War. Some scholars assume that his name is cognate to that of King Priam of Troy.

Systems of Survival: A Dialogue on the Moral Foundations of Commerce and Politics is a book written by American urban activist Jane Jacobs in 1992.

It describes two fundamental and distinct ethical systems, or syndromes as she calls them: that of the Guardian and that of Commerce. She argues that these supply direction for the conduct of human life within societies, and understanding the tension between them can help us with public policy and personal choices.
