Bodie ghost town

A ghost town is a town that has been abandoned, usually because the economic activity that supported it has failed or because of natural or human-caused disasters. Ghost towns are almost stereotypically common in mining areas, particularly the western United States following the Gold rushes of the 19th century, but similar derelict mining camps can be found in Canada, Australia and elsewhere.

Yellow-rattle

Yellow rattle (Rhinanthus minor) is a flowering plant in the family Scrophulariaceae. This family comprises "220-300 genera and 4000-4500 species. The family has a cosmopolitan distribution, with the majority found in temperate areas, including tropical mountains. Other members of the family include Digitalis, Linaria and Verbascum. Yellow rattle is a semi-parasitic plant that gains some of its nutrients from the roots of neighbouring plants. The name refers to the seedpods, which contain loose, rattling seeds when ripe.

Red-crested Pochard

The Red-crested Pochard (Netta rufina) is a large diving duck. Their breeding habitat is lowland marshes and lakes in southern Europe and southern and central Asia. They are somewhat migratory, and northern birds winter further south and into north Africa. These birds feed mainly by diving or dabbling. They eat aquatic plants, and typically upend for food more than most diving ducks.

Compound eye of a dragonfly

A compound eye is a visual organ found in certain arthropods. The compound eye consists of between 12 and 1,000 ommatidia, little dark/bright sensors. The image perceived by the arthropod is "recalculated" from the numerous ommatidia which point in slightly different directions. In contrast to other eye types, there is no central lens or retina. Though the resulting image is poor in resolution, it can detect quick movements and, in some cases, the polarization of light. Dragonflies have about 30,000 facets to their compound eyes, giving them nearly a 360° field of vision.

First Photograph by Joseph Nicéphore Niépce

The first photograph is considered to be this image produced in 1826 by the French inventor Nicéphore Niépce on a polished pewter plate covered with a petroleum derivative called bitumen of Judea. It was produced with a camera, and required an eight hour exposure in bright sunshine. However this process turned out to be a dead end and Niépce subsequently began experimenting with silver compounds based on a process discovered by Johann Heinrich Schultz in 1724.

Planet Mars

Mars, the fourth planet from the Sun, is named after the Roman god of war because of its blood red color. Mars has two small, oddly-shaped moons, Phobos and Deimos, named after the sons of the Greek god Ares. At some point in the future Phobos will be broken up by gravitational forces. The atmosphere on Mars is 95% carbon dioxide. In 2003 methane was also discovered in the atmosphere. Since methane is an unstable gas, this indicates that there must be (or have been within the last few hundred years) a source of the gas on the planet.

Twin Linear Aerospike XRS-2200 Engine

A test firing of twin linear XRS-2200 Aerospike engines. The aerospike engine is a type of rocket engine that maintains its efficiency across a wide range of altitudes through the use of an aerospike nozzle.

A standard rocket engine uses a bell shaped nozzle to contain and direct the exhaust gases. However the optimum shape of the bell depends on the air pressure, which decreases as the rocket climbs. An aerospike uses the air flowing past the rocket to form half of a 'virtual bell' which automatically compensates for the reducing pressure.

Water Buffalo from Indonesia

The Water Buffalo is a very large ungulate. It probably survives in the wild in India, Nepal, Bhutan and Thailand; is very widespread as a domestic animal in Asia, South America. North Africa and Europe; and is feral in northern Australia. Wild-living populations of Water Buffalo also exist in much of South-east Asia but their origin is uncertain: they may be the descendants of wild Water Buffalo, formerly domesticated ferals, or a mixture of both. The population of wild Water Buffalo has become very sparse.

Nuclear detonation from the "Tumbler Snapper" test series showing fireball and "rope tricks"

A rope trick is the whimsical term given by physicist Dr. John Malik to the curious lines and spikes which emanate from the fireball of a nuclear explosion just after detonation. The image is from the Tumbler-Snapper test series of 1952.

The surface of the fireball is over 20,000 kelvins and emits huge amounts of visible light radiation. The 'rope tricks' which protrude from the bottom of the fireball are caused by the heating, rapid vaporization and then expansion of the mooring cables tethering the tower supporting the nuclear bomb at the start of the test.

Geisha

Women dressed as geisha in Kyoto, Japan. They are wearing traditional kimonos and geta. Geisha (芸者) are traditional Japanese artist-entertainers. Geisha were very common in the 18th and 19th centuries, and are still in existence today, although their numbers are dwindling. The geisha tradition evolved from the taikomochi or hōkan, similar to court jesters. Geisha were traditionally trained from young childhood although modern geisha begin their training, which remains extremely long and difficult, at much older age.

Plunging bronco

Bronc riding is a rodeo sport that involves a rider getting on an untamed horse or bronco, held in a small pipe enclosure, and attempting to stay on the horse's back as the horse is released into the arena. The rider tightly grips a handle which is strapped to the horse, and the untamed horse naturally tries to throw or buck off the rider. Horses, being prey animals, do not care to have things on their backs. The rider must stay on the horse for 8 seconds without touching the horse with his free hand.

Four-stroke cycle

The four-stroke cycle of an internal combustion engine is the cycle most commonly used for automotive and industrial purposes today, including cars, trucks, and generators. The cycle was invented by Nikolaus Otto in 1876, and is also called the Otto cycle. The cycle is characterized by four strokes, or straight movements in a single direction, of the piston.

Pin tumbler lock

The pin tumbler lock is a lock mechanism that utilizes a group of pins of varying lengths to prevent opening the lock without the correct key. Pin tumblers are most commonly employed in cylinder locks, but may also be found in tubular or radial locks. When the correct key is inserted, the gaps between the key pins (red) and driver pins (blue) align with the edge of the plug (yellow).

Spider capturing prey

Predation is an interaction between organisms (animals) in which one organism captures and feeds upon another called the prey. Although predation most often refers to carnivory, in ecology it can also include many other types of feeding behaviors including parasitism, parasitoidism, and herbivory.

Antartic icefish larvae

Icefish are a type of Antarctic fish belonging to various families, including the Channichthyidae family. They have no haemoglobin and their blood is transparent. They feed on krill, copepods, and other fish. Icefish rely on well-oxygenated water and absorb oxygen directly through the skin as they lack red blood cells.

Atmosphere of Jupiter

The atmosphere of Jupiter as seen from Voyager 1, including the anticyclonic storm known as the Great Red Spot.

Jupiter's atmosphere is composed of ~81% hydrogen and ~18% helium with ~1% of other substances. This atmospheric composition is very close to the composition of the solar nebula. Saturn has a similar composition, but Uranus and Neptune have much less hydrogen and helium.

The Earth's atmosphere is quite different, being primarily composed of nitrogen.

Blue Sky

Weather lore, the informal folklore related to the prediction of the weather, suggests that the cumulus humilis clouds in this sky indicate a good day ahead. Such clouds show there is very little convection in the lower atmosphere, and the fact that it is well-formed indicates light winds at low levels. There is no cloud aloft, and thus no moisture or stable conditions or both. The cumulus congestus on the horizon suggests showers may be possible three or four hours from now, at the earliest, but chances are good it will remain a pleasant day through until the evening.

REICH

The Nuremberg rally (officially, Reichsparteitag, literally "imperial party congress") was the annual rally of the National Socialist German Workers' Party during many of the years of Nazi rule in Germany. The Reichsparteitage were held annually in Nuremberg from 1934 to 1938 and are thus usually referred to in English as the Nuremberg rallies. The 1934 rally was caught on film by Leni Riefenstahl as a propaganda piece called Triumph of the Will.
