LionThe lion (Panthera leo) is a large cat of the genus Panthera native to Africa and India. It has a muscular, broad-chested body; short, rounded head; round ears; and a hairy tuft at the end of its tail. It is sexually dimorphic; adult male lions are larger than females and have a prominent mane. It is a social species, forming groups called prides. A lion's pride consists of a few adult males, related females, and cubs. Groups of female lions usually hunt together, preying mostly on large ungulates.
Numerical stabilityIn the mathematical subfield of numerical analysis, numerical stability is a generally desirable property of numerical algorithms. The precise definition of stability depends on the context. One is numerical linear algebra and the other is algorithms for solving ordinary and partial differential equations by discrete approximation. In numerical linear algebra, the principal concern is instabilities caused by proximity to singularities of various kinds, such as very small or nearly colliding eigenvalues.
Chinese guardian lionsChinese guardian lions, or imperial guardian lions, are a traditional Chinese architectural ornament, but the origins lie deep in much older Indian Buddhist traditions. Typically made of stone, they are also known as stone lions or shishi (). They are known in colloquial English as lion dogs or foo dogs / fu dogs. The concept, which originated and became popular in Chinese Buddhism, features a pair of highly stylized lions—often one male with a ball which represents the material elements and one female with a cub which represents the element of spirit— that were thought to protect the building from harmful spiritual influences and harmful people that might be a threat.
Lion (heraldry)The lion is a common charge in heraldry. It traditionally symbolises courage, nobility, royalty, strength, stateliness and valour, because historically the lion has been regarded as the "king of beasts". The lion also carries Judeo-Christian symbolism. The Lion of Judah stands in the coat of arms of Jerusalem. Similar-looking lions can be found elsewhere, such as in the coat of arms of the Swedish royal House of Bjelbo, from there in turn derived into the coat of arms of Finland, formerly belonging to Sweden.
Asiatic lionThe Asiatic lion, also known as the Persian lion, is a population of Panthera leo leo that today survives in the wild only in India. Since the turn of the 20th century, its range has been restricted to Gir National Park and the surrounding areas in the Indian state of Gujarat. Historically, it inhabited much of southwest Asia to northern India. The first scientific description of the Asiatic lion was published in 1826 by the Austrian zoologist Johann N. Meyer, who named it Felis leo persicus.
