The Elephant's Trunk Nebula is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396 located in the constellation Cepheus about 2,400 light years away from Earth. [1] The piece of the nebula shown here is the dark, dense globule IC 1396A; it is commonly called the Elephant's Trunk nebula because of its ...
The Elephant's Foot is the nickname given to a large mass of corium, composed of materials formed from molten concrete, sand, steel, uranium, and zirconium. The mass formed beneath Reactor 4 of the Chernobyl Nuclear Power Plant, near Pripyat, Ukraine, during the Chernobyl disaster of 26 April 1986, and is noted for its extreme radioactivity.
Rubber room is the nickname given to the emergency egress bunkers located 40 feet (12 m) beneath the launch pads at Kennedy Space Center Launch Complex 39; there is one below each of the two pads. Built in the 1960s for the Apollo program, they were intended to provide a safe refuge for personnel on the launch pad in the event of an imminent ...
Elephant Butte Dam or Elephant Butte Dike, originally Engle Dam, [2] is a concrete gravity dam on the Rio Grande near Truth or Consequences, New Mexico, in the United States. The dam impounds Elephant Butte Reservoir , which is used mainly for agriculture but also provides for recreation, hydroelectricity, and flood and sediment control.
Elephant trunk (astronomy) The "Pillars of Creation" in the Eagle Nebula. Elephant trunks (more formally, cold molecular pillars[1]) are a type of interstellar matter formations found in molecular clouds. They are located in the neighborhood of massive O type and B type stars, which, through their intense radiation, can create expanding regions ...
Von Neumann's elephant. Von Neumann's elephant is a problem in recreational mathematics, consisting of constructing a planar curve in the shape of an elephant from only four fixed parameters. It originated from a discussion between physicists John von Neumann and Enrico Fermi.
Log flume. A log flume or lumber flume is a watertight flume constructed to transport lumber and logs down mountainous terrain using flowing water. Flumes replaced horse- or oxen-drawn carriages on dangerous mountain trails in the late 19th century. Logging operations preferred flumes whenever a reliable source of water was available.
Copeton Dam is a major clay core and rock fill embankment dam with nine radial gates and a gated concrete chute spillway across the Gwydir River upstream of Bingara in the New England region of New South Wales, Australia. The dam's purpose includes environmental flows, hydro-electric power generation, irrigation, and water supply.
