SimHealth: The National Health Care Simulation is a management simulation video game, developed by Thinking Tools and published by Maxis with assistance from the Markle Foundation for MS-DOS in 1994. It is a simulation of the U.S. Healthcare system. The game was released during Congressional debates on the Clinton health care plan.

Due to the complexity of the game, SimHealth was seen as being very difficult. Armed with none of the tongue-in-cheek humor that Maxis's prior games were known for, the only real link to the franchise was the SimCity 2000-inspired user interface. The game was seen as more serious than other Maxis games. Noel Fritzinger, who with Lyman Orton first conceptualized CommunityViz, says that his inspiration came from seeing SimHealth and wondering if the same concepts could be applied to real-world land-use planning.

Fifty-eight selected navigational stars are given a special status in the field of celestial navigation. Of the approximately 6,000 stars visible to the naked eye under optimal conditions, the selected stars are among the brightest and span 38 constellations of the celestial sphere from the declination of −70° to +89°. Many of the selected stars were named in antiquity by the Babylonians, Greeks, Romans, and Arabs.

The star Polaris, often called the "North Star", is treated specially due to its proximity to the north celestial pole. When navigating in the Northern Hemisphere, special techniques can be used with Polaris to determine latitude or gyrocompass error. The other 57 selected stars have daily positions given in nautical almanacs, aiding the navigator in efficiently performing observations on them. A second group of 115 "tabulated stars" can also be used for celestial navigation, but are often less familiar to the navigator and require extra calculations.

For purposes of identification, the positions of navigational stars — expressed as declination and sidereal hour angle — are often rounded to the nearest degree. In addition to tables, star charts provide an aid to the navigator in identifying the navigational stars, showing constellations, relative positions, and brightness.

🔗 Computing

In computer programming, indentation style is a convention, a.k.a. style, governing the indentation of blocks of source code. An indentation style generally involves consistent width of whitespace (indentation size) before each line of a block, so that the lines of code appear to be related, and dictates whether to use space or tab characters for the indentation whitespace.

Skid Row is a neighborhood in Downtown Los Angeles. The area is also known as Central City East.

As of a 2019 count, the population of the district was 4,757. Skid Row contains one of the largest stable populations (about 2,783) of homeless people in the United States and has been known for its condensed homeless population since the 1930s. Its long history of police raids, targeted city initiatives, and homelessness advocacy make it one of the most notable districts in Los Angeles.

Covering fifty city blocks (2.71 sq mi) immediately east of downtown Los Angeles, Skid Row is bordered by Third Street to the north, Seventh Street to the south, Alameda Street to the east, and Main Street to the west.

🔗 Psychology

Bedtime procrastination or revenge bedtime procrastination is a psychological phenomenon in which people stay up later than they desire in an attempt to have control over the night because they perceive themselves (perhaps subconsciously) to lack influence over events during the day.

🔗 Technology 🔗 China/Chinese history 🔗 China 🔗 Lists 🔗 Invention

China has been the source of many innovations, scientific discoveries and inventions. This includes the Four Great Inventions: papermaking, the compass, gunpowder, and printing (both woodblock and movable type). The list below contains these and other inventions in China attested by archaeological or historical evidence.

The historical region now known as China experienced a history involving mechanics, hydraulics and mathematics applied to horology, metallurgy, astronomy, agriculture, engineering, music theory, craftsmanship, naval architecture and warfare. By the Warring States period (403–221 BC), inhabitants of the Warring States had advanced metallurgic technology, including the blast furnace and cupola furnace, while the finery forge and puddling process were known by the Han Dynasty (202 BC–AD 220). A sophisticated economic system in imperial China gave birth to inventions such as paper money during the Song Dynasty (960–1279). The invention of gunpowder during the mid 9th century led to an array of inventions such as the fire lance, land mine, naval mine, hand cannon, exploding cannonballs, multistage rocket and rocket bombs with aerodynamic wings and explosive payloads. With the navigational aid of the 11th century compass and ability to steer at high sea with the 1st century sternpost rudder, premodern Chinese sailors sailed as far as East Africa. In water-powered clockworks, the premodern Chinese had used the escapement mechanism since the 8th century and the endless power-transmitting chain drive in the 11th century. They also made large mechanical puppet theaters driven by waterwheels and carriage wheels and wine-serving automatons driven by paddle wheel boats.

The contemporaneous Peiligang and Pengtoushan cultures represent the oldest Neolithic cultures of China and were formed around 7000 BC. Some of the first inventions of Neolithic China include semilunar and rectangular stone knives, stone hoes and spades, the cultivation of millet and the soybean, the refinement of sericulture, rice cultivation, the creation of pottery with cord-mat-basket designs, the creation of pottery vessels and pottery steamers and the development of ceremonial vessels and scapulimancy for purposes of divination. The British sinologist Francesca Bray argues that the domestication of the ox and buffalo during the Longshan culture (c. 3000–c. 2000 BC) period, the absence of Longshan-era irrigation or high-yield crops, full evidence of Longshan cultivation of dry-land cereal crops which gave high yields "only when the soil was carefully cultivated," suggest that the plough was known at least by the Longshan culture period and explains the high agricultural production yields which allowed the rise of Chinese civilization during the Shang Dynasty (c. 1600–c. 1050 BC). Later inventions such as the multiple-tube seed drill and heavy moldboard iron plough enabled China to sustain a much larger population through greater improvements in agricultural output.

For the purposes of this list, inventions are regarded as technological firsts developed in China, and as such does not include foreign technologies which the Chinese acquired through contact, such as the windmill from the Middle East or the telescope from early modern Europe. It also does not include technologies developed elsewhere and later invented separately by the Chinese, such as the odometer, water wheel, and chain pump. Scientific, mathematical or natural discoveries, changes in minor concepts of design or style and artistic innovations do not appear on the list.
