Figure-eight-shaped waggle dance of the honeybee (Apis mellifera). A waggle run oriented 45° to the right of ‘up’ on the vertical comb (A) indicates a food source 45° to the right of the direction of the sun outside the hive (B). The abdomen of the dancer appears blurred because of the rapid motion from side to side.

L'assorbimento totale del piombo (numero atomico 82) dei raggi gamma, in un funzione dell'energia dei raggi stessi, vengono distinti i contributi dei tre effetti. A bassa energia il meccanismo dominante è l'effetto fotoelettrico mentre per energie superiori a 5 MeV, domina la produzione di coppie elettrone-positrone.
Introducción del documento original de la Declaración, impresa el 4 de julio de 1776 con la supervisión de Jefferson. La copia manuscrita se imprimió después (como se observa en la ficha al principio de este artículo). Téngase en cuenta que los tipos de letra de la introducción difieren entre las dos versiones.[125]​

Det historiske kommunevåpenet for Re, som viste en gullfarget liljehaspel på grønn bakgrunn.

English: This shaded relief image of Mexico's Yucatán Peninsula shows a subtle, but unmistakable, indication of the Chicxulub impact crater. Most scientists now agree that this impact was the cause of the Cretatious-Tertiary Extinction, the event 65 million years ago that marked the sudden extinction of the dinosaurs as well as the majority of life then on Earth.
A set of points on the Strathspey Railway in Scotland. The facing point lock in the middle will need to be withdrawn using one of the two levers on the left before the points themselves can be moved using the other lever. Once the points have been moved the lock will be pushed in again to lock the points in position.

Driving in certain conditions may trigger 'highway hypnosis' in some people, which is an example of automaticity. Those who experience highway hypnosis often drive for long distances, responding to external events in the correct and safe manner, but have no memory of the time spent under highway hypnosis as a result.

John Gadsby Chapman depicts Pocahontas, wearing white, being baptized Rebecca by Anglican minister Alexander Whiteaker in Jamestown, Virginia; this event is believed to have taken place in 1613 or 1614. She kneels, surrounded by family members and colonists. Her brother Nantequaus turns away from the ceremony. The baptism took place before her marriage to Englishman John Rolfe, who stands behind her. Their union is said to be the first recorded marriage between a European and a Native American. The scene symbolizes the belief of Americans at the time that Native Americans should accept Christianity and other European ways. Chapman (1808-1889), born in Alexandria, Virginia, studied art in Italy and became known for his portrait and historical paintings and his rich use of color. The dimensions of this oil painting on canvas are 365.76 cm by 548.64 cm (144.00 in by 216.00 in).

A full moon and 25-second exposure allowed sufficient light for this photo to be taken at Amundsen–Scott South Pole Station during the long Antarctic night. The station can be seen at far left, the power plant in the centre and the mechanic's garage in the lower right. The green light in the background is the aurora.
English: A full moon and 25 second exposure allowed sufficient light into this photo taken at Amundsen-Scott South Pole Station during the long Antarctic night. The new station can be seen at far left, power plant in the center and the old mechanic's garage in the lower right. Red lights are used outside during the winter darkness as their spectrum does not pollute the sky, allowing scientists to conduct astrophysical studies without artificial light interference. There is a background of green light. This is the Aurora Australis, which dances thorugh the sky virtually all the time during the long Antarctic night (winter).The photo's surreal appearance makes the station look like a futuristic Mars Station. Français : Vue de la station américaine Amundsen-Scott au pôle sud, éclairée par la pleine lune, durant la longue nuit polaire. La nouvelle station est visible tout à gauche, la centrale électrique au centre et l'ancien atelier de mécanique en bas à droite. Durant la nuit polaire, seule la lumière rouge est utilisée pour limiter la pollution lumineuse et ne pas perturber les expériences d'astrophysique menées dans la base. La lumière verte est due aux aurores australes qui sont quasi-permanentes durant la nuit polaire. L'apparence surréaliste de la photo fait penser à une base futuriste sur Mars.
