An ambigram is a calligraphic or typographic design with multiple interpretations as written words. Alternative meanings are often yielded when the design is transformed or the observer moves, but they can also result from a shift in mental perspective. This animation shows a half-turn ambigram of the word ambigram. The word is written calligraphically with 180-degree rotational symmetry, such that it reads identically when viewed upside down.

The San Francisco cable car system is a cable-car rail network in San Francisco, California. Conceived by Andrew Smith Hallidie, the system's first line was the Clay Street Hill Railroad, which opened on August 2, 1873. By 1890, the system had expanded to twenty-three lines, of which three remain in operation as of 2023. The cars are pulled by a cable running below the street, which is held by a grip that extends from the car through a slit in the street surface, between the rails. This 2016 photograph shows a cable car traveling on Hyde Street, with Alcatraz Island and Fisherman's Wharf visible in the background. Photograph credit: Thomas Wolf

Texas Raiders was an American Boeing B-17 Flying Fortress built by Douglas-Long Beach. In 1967, it was purchased by a group of the Commemorative Air Force's Gulf Coast Wing, which maintained and flew the aircraft out of Conroe-North Houston Regional Airport in Conroe, Texas. It was destroyed on November 12, 2022, in a mid-air collision with a Bell P-63 Kingcobra at an air show at Dallas Executive Airport. All five people on board Texas Raiders and the pilot of the P-63 were killed. This photograph, taken in 2019 at Ellington Airport in Houston, shows Texas Raiders re-enacting a scene from the film Tora! Tora!

Lidia Patty (born 1969) is a Bolivian politician who is a former member of the Chamber of Deputies for the Movimiento al Socialismo (Movement for Socialism). A member of the Kallawaya – an indigenous people native to western Bolivia – she was a domestic worker and schoolteacher before entering politics. After maintaining a low profile in parliament, Patty gained national attention after her term ended when she opened a complaint for the 2019 Bolivian political crisis, which resulted in the criminal prosecution of former president Jeanine Áñez. A polemical figure for her frequent denunciations of opposition and ruling party officials, Patty ran unsuccessfully in the 2022 election for ombudsman of Bolivia, and was briefly the Bolivian consul to Puno, Peru, in 2023 before being withdrawn amid deteriorating relations between the two countries. This official portrait of Patty as a member of the Plurinational Legislative Assembly was taken in 2016. Photograph credit: Alejandra Vaca

A Kármán vortex street is a process in fluid dynamics in which a repeating pattern of swirling vortices, caused by vortex shedding, is responsible for the unsteady flow separation of a fluid around blunt bodies. It is named after the Hungarian-American engineer and fluid dynamicist Theodore von Kármán. This satellite image, taken by NASA's Landsat 7 in 1999, shows a Kármán vortex street caused by wind flowing around the Juan Fernández Islands off the Chilean coast in the South Pacific Ocean. The flow of atmospheric air over obstacles such as islands can cause visible vortex streets when a cloud layer is present at a certain altitude. It can reach a length of more than 400 kilometres (250 miles) from the obstacle in such cases, with a typical vortex diameter of 20 to 40 km (12 to 25 mi). Photograph credit: Robert Cahalan, NASA

The hazelnut is the fruit of the hazel tree, including all nuts of the genus Corylus, especially those of the species Corylus avellana. Hazelnuts are used as a snack food, in baking and desserts, breakfast cereals such as muesli, confectionery, and also in combination with chocolate for chocolate truffles and products such as chocolate bars, Nutella and Frangelico liqueur. Hazelnut oil, pressed from hazelnuts, is strongly flavored and high in monounsaturated fat; it is used as a cooking oil and as a salad or vegetable dressing. Turkey is the world's largest producer of hazelnuts, accounting for 64% of total production in 2021. This photograph shows two whole hazelnuts alongside two kernels, one of which is peeled.

Edgar is an opera in three acts by Giacomo Puccini to an Italian libretto by Ferdinando Fontana, freely based on the play in verse La Coupe et les lèvres by Alfred de Musset. It premiered at La Scala in Milan in 1889 and was repeatedly revised until 1905, but Puccini did not regard it as a success, describing it as "warmed-up soup". The opera is still occasionally performed, including a 2005 recording by the Orchestra dell'Accademia Nazionale di Santa Cecilia conducted by Alberto Veronesi and featuring Plácido Domingo. This undated set design for act 3 of Edgar, from the archives of the music publisher Casa Ricordi, was created by Giuseppe Palanti with pencil and tempera on paper. It depicts an outdoor glade near Courtray in Flanders, the main setting of the opera. Set design credit: Giuseppe Palanti

The viscosity of a fluid is a measure of its resistance to deformation at a given rate. The SI unit of viscosity is the pascal-second. For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water. Viscosity quantifies the internal frictional force between adjacent layers of fluid that are in relative motion. For instance, when a viscous fluid is forced through a tube, it flows more quickly near the tube's axis than near its walls. This fluid animation shows a simulation of two fluids with different viscosities being poured into identical containers. The blue liquid on the left has a lower viscosity than the orange liquid on the right. Animation credit: Gvbox

The lion (Panthera leo) is a large cat species in the genus Panthera native to Africa and India. It has a muscular, broad-chested body; short, rounded head; round ears; and a hairy tuft at the end of its tail. It is sexually dimorphic; adult males are larger than females and have a prominent mane. The lion is a social species, forming groups called prides. A pride consists of a few adult males, related females, and cubs. Groups of female lions usually hunt together, preying mostly on large ungulates. It is an apex and keystone predator. Although some lions scavenge when opportunities occur and have been known to hunt humans, they typically do not actively seek out and prey on humans. This six-year-old male lion was photographed in the Phinda Private Game Reserve in KwaZulu-Natal, South Africa. Photograph credit: Charles J. Sharp |

The Presidio of San Francisco is a park and former United States Army post on the northern tip of the San Francisco Peninsula in the city of San Francisco, California, forming part of the Golden Gate National Recreation Area. The presidio was established as a fortified location in 1776, when New Spain founded it to gain a foothold in Alta California and the San Francisco Bay. It passed to Mexico in 1820, and in turn to the United States in 1848. As part of a military reduction program under the Base Realignment and Closure process from 1988, the United States Congress voted to end the presidio's status as an active military installation. In 1994, it was transferred to the National Park Service, ending 219 years of military use and beginning its next phase of mixed commercial and public use. This lithograph, published in 1822, shows the Presidio of San Francisco and its surroundings during the Spanish era, with the Golden Gate visible in the background to the right of the image.

Pobiti Kamani is a rock formation located in Varna Province, Bulgaria. There are a number of theories regarding its origin, with two broad hypotheses. According to one, the formations are the result of coral activity, while another explains the phenomenon with the prismatic weathering and desertification of the rocks, the formation of sand and limestone concretions, or lower Eocene bubbling reefs. The stone pillars were first described by the Russian archaeologist and historian Victor Teplyakov in 1829, and the site was designated a natural landmark in the late 1930s. This photograph shows the pillars of Pobiti Kamani in 2016. Photograph credit: Diego Delso

The barred owl (Strix varia), also known as the northern barred owl, the striped owl or the hoot owl, is a bird in the family Strigidae, the true owls. It is largely native to eastern North America, but has also expanded its range to the continent's west coast, where it is considered an invasive species. Its preferred habitat is mature forest, but it can also acclimate to various gradients of open woodlands. The barred owl's diet consists mainly of small mammals, but this species is an opportunistic predator and is known to prey upon other small vertebrates such as birds, reptiles and amphibians, as well as a variety of invertebrates. Barred owls are brown to gray overall, with dark striping on the underside. This barred owl was photographed in Whitby in Ontario, Canada. Photograph credit: Mdf
