Dungeons & Dragons is a fantasy tabletop role-playing game (RPG) originally designed by Gary Gygax and Dave Arneson. It was first published in 1974 by Tactical Studies Rules, Inc. (TSR). The game has been published by Wizards of the Coast since 1997. It was derived from miniature wargames, with a variation of the 1971 game Chainmail serving as the initial rule system. D&D's publication is commonly recognized as the beginning of modern role-playing games and the role-playing game industry.
Earth is the third planet from the Sun and the only astronomical object known to harbor life. According to radiometric dating and other evidence, Earth formed over 4.5 billion years ago. Earth's gravity interacts with other objects in space, especially the Sun and the Moon, which is Earth's only natural satellite. Earth orbits around the Sun in 365.256 solar days, a period known as an Earth sidereal year. During this time, Earth rotates about its axis 366.256 times, that is, a sidereal year has 366.256 sidereal days.
India, officially the Republic of India, is a country in South Asia. It is the seventh-largest country by area, the second-most populous country, and the most populous democracy in the world. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand and Indonesia.
Joan of Arc, nicknamed "The Maid of Orléans", is considered a heroine of France for her role during the Lancastrian phase of the Hundred Years' War, and was canonized as a Roman Catholic saint. She was born to Jacques d'Arc and Isabelle Romée, a peasant family, at Domrémy in northeast France. Joan claimed to have received visions of the archangel Michael, Saint Margaret, and Saint Catherine of Alexandria instructing her to support Charles VII and recover France from English domination late in the Hundred Years' War. The unanointed King Charles VII sent Joan to the Siege of Orléans as part of a relief army. She gained prominence after the siege was lifted only nine days later. Several additional swift victories led to Charles VII's consecration at Reims. This long-awaited event boosted French morale and paved the way for the final French victory.
The Moon is an astronomical body orbiting Earth as its only natural satellite. It is the fifth-largest satellite in the Solar System, and by far the largest among planetary satellites relative to the size of the planet that it orbits. The Moon is, after Jupiter's satellite Io, the second-densest satellite in the Solar System among those whose densities are known.
The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties. The structure of the table shows periodic trends. The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right. The columns, called groups, contain elements with similar chemical behaviours. Six groups have accepted names as well as assigned numbers: for example, group 17 elements are the halogens; and group 18 are the noble gases. Also displayed are four simple rectangular areas or blocks associated with the filling of different atomic orbitals.
The number π is a mathematical constant. It is defined as the ratio of a circle's circumference to its diameter, and it also has various equivalent definitions. It appears in many formulas in all areas of mathematics and physics. It is approximately equal to 3.14159. It has been represented by the Greek letter "π" since the mid-18th century, and is spelled out as "pi". It is also referred to as Archimedes' constant.
The Solar System is the gravitationally bound system of the Sun and the objects that orbit it, either directly or indirectly. Of the objects that orbit the Sun directly, the largest are the eight planets, with the remainder being smaller objects, the dwarf planets and small Solar System bodies. Of the objects that orbit the Sun indirectly—the moons—two are larger than the smallest planet, Mercury.
William Shakespeare was an English poet, playwright, and actor, widely regarded as the greatest writer in the English language and the world's greatest dramatist. He is often called England's national poet and the "Bard of Avon". His extant works, including collaborations, consist of some 39 plays, 154 sonnets, two long narrative poems, and a few other verses, some of uncertain authorship. His plays have been translated into every major living language and are performed more often than those of any other playwright.
George Smith Patton Jr., KCB was a general of the United States Army who commanded the U.S. Seventh Army in the Mediterranean theater of World War II, and the U.S. Third Army in France and Germany after the Allied invasion of Normandy in June 1944.
Washington, D.C., formally the District of Columbia and commonly referred to as D.C., Washington, or The District, is the capital of the United States. Founded after the American Revolution as the seat of government of the newly independent country, Washington was named after George Washington, the first president of the United States and a Founding Father. As the seat of the United States federal government and several international organizations, Washington is an important world political capital. The city, located on the Potomac River bordering Maryland and Virginia, is one of the most visited cities in the world, with more than 20 million tourists annually.
Freezing is a phase transition where a liquid turns into a solid when its temperature is lowered below its freezing point. In accordance with the internationally established definition, freezing means the solidification phase change of a liquid or the liquid content of a substance, usually due to cooling.
English is a West Germanic language that was first spoken in early medieval England and eventually became a global lingua franca. It is named after the Angles, one of the Germanic tribes that migrated to the area of Great Britain that later took their name, England. Both names derive from Anglia, a peninsula in the Baltic Sea. English is closely related to Frisian and Low Saxon, and its vocabulary has been significantly influenced by other Germanic languages, particularly Norse, and to a greater extent Latin and French.
A penis is the primary sexual organ that male animals use to inseminate sexually receptive mates during copulation. Such organs occur in many animals, both vertebrate and invertebrate, but males do not bear a penis in every animal species, and in those species in which the male does bear a so-called penis, the penises in the various species are not necessarily homologous.
Chryseobacterium greenlandense is an ultramicrobacteria species, of bacteria that is able to live for long periods of time in low-temperature, high-pressure, reduced-oxygen and nutrient-poor habitats. It is known to have survived for more than 120,000 years in an ice block in Greenland, at a depth of 3,000 metres (1.9 mi).
Herminiimonas is a genus of bacteria in the Oxalobacteraceae family. It contains Betaproteobacteria that have been isolated from spring and mineral waters. The type species, H. fonticola, was first recovered from the borehole of bottled mineral water in eastern Portugal.
Herminiimonas glaciei is a species of ultramicrobacterium in the family Oxalobacteraceae. These small gram-negative cells have a variable number of long flagella at the ends and sides of their rod-shaped bodies. With dimensions of 0.5–0.9 by 0.3–0.4 µm, H. glaciei is roughly 10 to 50 times smaller than Escherichia coli. Discovered in 2009, the species was isolated from 120,000 years old glacial ice, 3,042 metres (1.9 mi) deep, from Greenland. It was revived after a long-term incubation—seven months of oxygen-free growth at 2 °C, followed by growth on agar plates at 5 °C for almost five months. DNA sequence analysis suggests that with a sequence similarity of 99.6%, H. glaciei is most closely related to H. saxobsidens, a species originally isolated from lichen-colonized rock. Loveland-Curtze, head of the team of scientists from Pennsylvania State University who found the species, speculates that it may offer insight into the existence of organisms in extraterrestrial habitats.

Herminiimonas saxobsidens is a species of ultramicrobacteria. First reported in 2007, it was isolated from a rock surface colonized with lichens.
