Julius Richard Petri
Julius Richard Petri (; 31 May 185220 December 1921) was a German microbiologist who is generally credited with inventing the device known as the Petri dish, which is named after him, while working as assistant to bacteriologist Robert Koch. Life and career Petri was born in the town of Barmen (now a district of the city of Wuppertal), Germany, on 31 May 1852. He came from a distinguished family of scholars, and was the eldest son of Philipp Ulrich Martin Petri (18171864), a professor in Berlin, and Louise Petri. Petri's grandfather, Viktor Friedrich Leberecht Petri (1782–1857), was also a scholar, being both a director and professor at the Collegium Carolinum in Brunswick (Braunschweig), Germany. Petri initially studied medicine at the Kaiser Wilhelm Academy for Military Physicians (18711875) and received his medical degree in 1876. He continued his studies at the Charité Hospital in Berlin where his thesis on the chemistry of protein urine tests earned him his doctorate. ...

Rocky Mountains Park Act
The ''Rocky Mountains Park Act'' () was enacted on June 23, 1887, by the Parliament of Canada, establishing Banff National Park which was then known as "Rocky Mountains Park". The act was modelled on the '' Yellowstone Park Act'' passed by the United States Congress in 1881. The ''Rocky Mountains Park Act'' outlined the national park concept, balancing conservation and development Development or developing may refer to: Arts *Development (music), the process by which thematic material is reshaped * Photographic development *Filmmaking, development phase, including finance and budgeting * Development hell, when a proje ... interests.

Snow
Snow consists of individual ice crystals that grow while suspended in the atmosphere—usually within clouds—and then fall, accumulating on the ground where they undergo further changes. It consists of frozen crystalline water throughout its life cycle, starting when, under suitable conditions, the ice crystals form in the atmosphere, increase to millimeter size, precipitate and accumulate on surfaces, then metamorphose in place, and ultimately melt, slide, or Sublimation (phase transition), sublimate away. Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air. Snowflakes Nucleation, nucleate around particles in the atmosphere by attracting supercooling, supercooled water droplets, which Freezing, freeze in hexagonal-shaped crystals. Snowflakes take on a variety of shapes, basic among these are platelets, needles, columns, and Hard rime, rime. As snow accumulates into a snowpack, it may blow into drifts. Over time, accumulated snow m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fort Keogh
Fort Keogh is a former United States Army post located at the western edge of modern Miles City, Montana, Miles City, in the U.S. state of Montana. It is situated on the south bank of the Yellowstone River, at the mouth of the Tongue River (Montana), Tongue River. Colonel Nelson A. Miles, commanding the 5th Infantry Regiment (United States), 5th Infantry Regiment, founded the post in August 1876, in the wake of the Battle of the Little Bighorn, as a base for patrols to prevent the Cheyenne and Sioux involved in the battle from escaping to Canada. The fort was originally known as the Tongue River Cantonment for two years. When relocated one mile west in 1878, it was renamed Fort Keogh in honor of Captain Myles Keogh, who was killed at the Little Bighorn. In 1877, the fort became the headquarters for the newly created District of the Yellowstone (a sub-unit of the Department of Dakota), which was commanded by Miles. The development of Fort Keogh as a military installation soon sti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snowstorm
A winter storm (also known as snow storm) is an event in which wind coincides with varieties of precipitation that only occur at freezing temperatures, such as snow, Rain and snow mixed, mixed snow and rain, or freezing rain. In Continental climate, temperate continental and subarctic climates, these storms are not necessarily restricted to the winter season, but may occur in the late autumn and early spring as well. A snowstorm with strong winds and low visibility is called a blizzard. Formation Winter storms are formed when moist air rises up into the atmosphere, creating Low-pressure area, low pressure near the ground and clouds up in the air. The air can also be pushed upwards by hills or large mountains. The upward motion is called Lift (force), lift. The moisture is collected by the wind from large bodies of water, such as a big lake or the ocean. If temperature is below freezing, , near the ground and up in the clouds, precipitation will fall as snow, ice, rain and s ...

Guyou Hemisphere-in-a-square Projection
The Guyou hemisphere-in-a-square projection is a conformal map projection for the hemisphere. It is an oblique aspect of the Peirce quincuncial projection. History The projection was developed by of France in 1887. Formal description The projection can be computed as an oblique aspect of the Peirce quincuncial projection by rotating the axis 45 degrees. It can also be computed by rotating the coordinates −45 degrees before computing the stereographic projection; this projection is then remapped into a square whose coordinates are then rotated 45 degrees. Supplement No. 1 t''The Canadian Cartographer'' 13 The projection is conformal except for the four corners of each hemisphere's square. Like other conformal polygonal projections, the Guyou is a Schwarz–Christoffel mapping. Properties Its properties are very similar to those of the Peirce quincuncial projection: * Each hemisphere is represented as a square, the sphere as a rectangle of aspect ratio 2:1. * The part ...

Borosilicate Glass
Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10−6 K−1 at 20 °C), making them more resistant to thermal shock than any other common glass. Such glass is subjected to less thermal stress and can withstand temperature differentials without fracturing of about . It is commonly used for the construction of reagent bottles and flasks, as well as lighting, electronics, and cookware. For many other applications, soda-lime glass is more common. Borosilicate glass is sold under various trade names, including Borosil, Duran, Pyrex, Glassco, Supertek, Suprax, Simax, Bellco, Marinex (Brazil), BSA 60, BSC 51 (by NIPRO), Heatex, Endural, Schott, Refmex, Kimax, Gemstone Well, United Scientific, and MG (India). Single-ended self-starting lamps are insulated with a mica disc and contained in a borosilicate glass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
