Entstehung natürlicher Steinbögen
 1. Durch den Einbruch der Antiklinalen brachen die durch Hebung entstandenen Risse im Sandstein auf.
 2. Durch Erosion vergrößerte sich die Oberfläche der Risse, wodurch die Erosion noch rascher fortschreiten konnte, so dass lange, rippenartige Strukturen entstanden.
 3. Felsen bröckeln ab und durchbrechen die Rippen, in wenigen Fällen entstanden Löcher in den Wällen.
 4. Die so entstandenen Löcher werden durch Wind und Wetter weiter erodiert, Wasser dringt teilweise in den Sandstein ein und sprengt beim Gefrieren weitere Felsen heraus.

Passasiers het 'n groter kans op oorlewing sou 'n waterstofvliegtuig tydens die vroeë fase van aanloop of die laaste fase van landing verongeluk. Waterstof verbrand in 'n enkele groot steekvlam as die tenks beskadig word, nie in 'n vlammemeer soos die tradisionele vliegtuig-brandstof keroseen nie. Die foto toon die oorblyfsels van 'n KLM-makrostraler wat in 1977 op die aanloopbaan van die lughawe van Tenerife, Kanariese Eilande met 'n Pan Am-makrostraler gebots het. In hierdie grootste vliegtuigongeluk ooit is 583 mense dood nadat albei stralers aan die brand geslaan het

This figure shows a pressure topography plot during a normal swallow, measured using a 36-channel high-resolution manometry system. Time is on the horizontal axis and length along the esophagus on the vertical axis. Pressure magnitude is encoded in color corresponding to the scale shown at the bottom. High-pressure regions are denoted by the red end of the spectrum while the low pressure regions by the blue end.

Anton von Werner, Farbskizze zum Saarbrücker Rathauszyklus „Ankunft König Wilhelms I. in Saarbrücken am 9. August 1870“, Saarbrücken und St. Johann waren zu Beginn des Deutsch-Französischen Krieges von den Franzosen besetzt worden. Drei Tage nach der Erstürmung der Spicherer Höhen durch die Truppen des Norddeutschen Bundes in der Schlacht bei Spichern zog der preußische König Wilhelm I. siegreich über die Alte Brücke in Saarbrücken ein. Damit war die unmittelbare Kriegsgefahr für Dillingen und die übrigen Saarorte gebannt (Deutsches Historisches Museum, Zeughaus, Berlin)

Glideren fordeler på skift dampen til den dobbeltvirkende cylinders to kamre, og åbner for afgang af dampen fra den modsatte side af stemplet. En lodret roterende aksel med to kugler er centrifugalregulator, der via en trækstang drøvler damptilførslen, når hastigheden går op og kuglerne svingere længere ud, og omvendt når hastigheden går ned. Herved sikres en konstant arbejdshastighed

A mesma fonte de som está irradiando ondas sonoras à mesma frequência no mesmo meio. Porém, agora a fonte está se movendo com uma velocidade vf = 0,7c (Mach 0,7). Já que a fonte está se movendo, cada nova frente de onda é um pouco deslocada para a direita. Como resultado, as frentes de onda começam a se "amontoar" à direita (à frente) e a se "espalhar" à esquerda (atrás) da fonte. Um observador à frente da fonte irá ouvir uma frequência mais alta fo= c + 0⁄c - 0.7cff= 3.33ff e um observador atrás da fonte irá ouvir uma frequência mais baixa fo= c - 0⁄c + 0.7cff= 0.59 ff.
English: The same sound source is radiating sound waves at a constant frequency in the same medium. However, now the sound source is moving to the right with a speed vs = 0.7 c (Mach 0.7). The wave-fronts are produced with the same frequency as before. However, since the source is moving, the center of each new wavefront is now slightly displaced to the right. As a result, the wave-fronts begin to bunch up on the right side (in front of) and spread further apart on the left side (behind) of the source. An observer in front of the source will hear a higher frequency f = ( c + v r c − v s ) f 0 = 3.33 f 0 {\displaystyle f=\left({\frac {c+v_{r}}{c-v_{s}}}\right)f_{0}=3.33f_{0}\,} , and an observer behind the source will hear a lower frequency f = ( c − v r c + v s ) f 0 = 0.59 f 0 {\displaystyle f=\left({\frac {c-v_{r}}{c+v_{s}}}\right)f_{0}=0.59f_{0}\,} http://weelookang.blogspot.com/2011/09/ejs-open-source-1-dimension-doppler.html
Kaart 4. Een kaart 'om te zien'. De spreiding is nu zichtbaar, en juist. De kaart geeft twee soorten antwoorden: 1) de klasse 'inwoners per mi2' per staat is afleesbaar; 2) de spreiding is waar te nemen (=zien). Deze spreiding is niet waar te nemen in bovenstaande voorbeelden. Indien het doel van de kaart er aanleiding toe zou geven, zou er wellicht één kleine verbetering te maken zijn; het label plaatsen zoals in kaart 1. Bij het toevoegen van nog meer opties aan een kaart moet echter altijd de vraag gesteld worden of dit het beantwoorden van 'vraag 2' niet vertroebelt.

Um padrão de nuvem de ondas gravitacionais —similiar a um navio que desperta na zona de vento atrás da Ilha de Amesterdão, no extremo sul do Oceano Índico. A ilha gera movimento de onda no vento que passa sobre ele, criando nuvens orográficas regularmente espaçadas. As cristas da onda elevam e esfriam o ar para formar nuvens, enquanto as calhas permanecem muito baixas para a formação da nuvem. Observe que, enquanto o movimento da onda é gerado pelo levantamento orográfico, não é necessário. Em outras palavras, uma nuvem geralmente se forma no pico. Veja a nuvem de ondas.

Las fuerzas en juego en el caso de un planeta con una protuberancia ecuatorial debido a la rotación.



 Flecha roja: gravedad, flecha Verde: la fuerza normal , flecha Azul: la fuerza resultante 

La fuerza resultante proporciona la fuerza centrípeta requerida. Sin esta fuerza centrípeta, los objetos sin fricción se deslizarían hacia el ecuador.

  En los cálculos, cuando se usa un sistema de coordenadas que gira conjuntamente con la Tierra, el vector de la fuerza centrífuga nocional apunta hacia afuera, y es tan grande como el vector que representa la fuerza centrípeta.
Description: This sequence of three images shows the forces that are at play on a rotating planet such as Earth. The two forces that are at play are the force of gravitation, depicted in red, and the normal force, depicted in green. The blue arrow represents the resultant force of the two forces that are at play. The diagram displays a sideways view. The forces represented in the diagram account for the motion with respect to the inertial frame of reference that is co-moving with the center of mass of the Earth. Because of its rotation, the Earth is not spherical in shape, it is an oblate spheroid. The force of gravitation is (to a good approximation) directed towards the center of the Earth, and the normal force acts perpendicular to the local surface. On the poles and on the equator the two forces act exactly in opposite direction. On all other latitudes the angle between the two forces is not 180 degrees, so there is a resultant force. If the equatorial bulge is in equilibrium with the planet's rotation rate then at every latitude this resultant force exerts precisely the amount of centripetal force that is necessary to maintain an even thickness of the atmospheric layer. The solid Earth is ductile. Whenever the shape of the solid Earth is not quite in equilibrium with its rate of rotation, then there are shear stresses. These shear stresses then deform the solid Earth over a period of millions of years until the shear stresses are resolved. Depending on the circumstances, this diagram or the diagram of Image:Forces_oblate_spheroid.gif will be most useful. Created: 16 January 2006 Author: Cleonis

Ses jaar ná sy afsterwe, in 1380, is 'n grafmonument vir Petrarca op 'n plein net buite die kerk Santa Maria Assunta opgerig. Sy sterflike oorskot rus in 'n sarkofaag uit rooierige Verona-marmer - of dele daarvan. Terwyl sy regterarm reeds deur 'n geestelike gesteel is, het DNS-ontledings in 2004 getoon dat die sarkofaag die skedel van 'n vrou bevat. Gedurende die 16de en 17de eeu was dit 'n makabere stokperdjie vir welvarende families om die skedels van beroemde personlikhede te versamel. So is 'n beroep op moontlike "besitters" gedoen om Petrarca se skedel terug te gee
