A single-pitch angklung from Bandung, Indonesia. The angklung is a musical instrument made of a varying number of bamboo tubes attached to a bamboo frame. The base of the frame is held in one hand, whilst the other hand shakes the instrument. This causes a repeating note to sound. The tubes are carved to have a resonant pitch when struck and are tuned to octaves. When single-pitch angklung such as this are used in angklung ensemble, each of the performers plays just one note or more, but together they produce complete melodies.

An illustration by Sidney Hall for Urania's Mirror, a set of 32 astronomical star chart cards first published in November 1824. These cards, which were based on Alexander Jamieson's A Celestial Atlas, had holes punched allowing them to be held up to the light to see a depiction of the constellation's stars.

This card, Plate 28 in the series, depicts six constellations: the defunct Psalterium Georgii ('George's Harp'), Fluvius Eridanus ('the river'), Cetus (also known as 'the whale'), Officina Sculptoris ('sculptor'), Fornax Chemica ('the furnace'), and the defunct Machina Electrica ('the generator').

Anthidium florentinum, a species of bee in the family Megachilidae. Bees are flying insects closely related to wasps and ants that are involved in pollination. There are nearly 20,000 known species of bees in seven recognized biological families. Bees are found on every continent except Antarctica, in every habitat on the planet that contains insect-pollinated flowering plants. Bees range in size from tiny stingless bee species whose workers are less than 2 millimetres (0.08 in) long, to Megachile pluto, whose females can attain a length of 39 millimetres (1.54 in).

Martin Ryckaert (bap. 1587 – 1631) was a Flemish painter known for his small, usually imaginary landscapes in an Italianate style. Born to the Ryckaert family in Antwerp, he is believed to have studied under his father David Ryckaert I and later Tobias Verhaecht. In 1611, he was registered as a "painter with one arm" at the Guild of Saint Luke in Antwerp, where he was also active in the local chamber of rhetoric.

This painting of Ryckaert as a king was completed by Anthony van Dyck, reportedly a close friend, between 1627 and 1632. It now hangs at the Museo del Prado in Madrid, Spain.

Intentional camera movement is a photography technique in which a camera is moved during the exposure for a creative or artistic effect. This causes the image points to move across the recording medium, producing an apparent streaking in the resulting image. The image shown here depicts a bluebell wood on Ashridge Estate in Hertfordshire, England; the intentional camera movement along the vertical plane has created an impressionistic effect.

Meripilus giganteus is a polypore fungus in the family Meripilaceae. It causes a white rot in various types of broadleaved trees, particularly beech. This bracket fungus is often found in large clumps at the base of trees, although fruiting bodies are sometimes found some distance from the trunk, parasitizing the roots. M. giganteus has a circumboreal distribution in the Northern Hemisphere, and is widely distributed in Europe. In the field, it is recognizable by the large, multi-capped fruiting body, as well as its pore surface that quickly darkens black when bruised or injured.

A Daruma doll (Japanese: 達磨) is a hollow, round, traditional Japanese doll modeled after Bodhidharma, the founder of the Zen tradition of Buddhism. These dolls, though typically red and depicting a bearded man (Dharma), vary greatly in color and design depending on region and artist. Though considered an omocha, meaning toy, by some, Daruma has a design that is rich in symbolism and is regarded more as a talisman of good luck to the Japanese. They are seen as symbols of perseverance and good luck, making them a popular gift of encouragement.

The Horse Fair is an oil painting on canvas completed by the French artist Rosa Bonheur between 1852 and 1853. Depicting dealers selling horses on the streets in Paris, the work was first exhibited at the Paris Salon in 1853. In 1887, having been held by several private collectors, the painting was donated by Cornelius Vanderbilt II to the Metropolitan Museum of Art. It is one of Bonheur's most popular works, such that Queen Victoria requested a private viewing at Buckingham Palace during the painting's 1855–1857 tour of England.

Fremantle Prison is a former Australian prison and World Heritage Site in Fremantle, Western Australia. The six-hectare (15-acre) site includes the prison cellblocks, gatehouse, perimeter walls, cottages, and tunnels. Constructed between 1851 and 1859 using convict labour, the prison was initially used for convicts transported from Britain, but was transferred to the colonial government in 1886 for use for locally-sentenced prisoners. Decades of prisoner discontent, culminating in a 1988 riot that saw guards taken hostage and a fire cause $1.8 million worth of damage, led to the prison being closed in 1991. Since then, Fremantle Prison has been conserved as a heritage and tourism site, and various restoration works have been undertaken.

Salak (Salacca zalacca) is the fruit of a species of palm tree native to Java and Sumatra in Indonesia. The fruits grow in clusters at the base of the palm, and are also known as snake fruit due to the reddish-brown scaly skin. Individual fruits are about the size and shape of a ripe fig, with a distinct tip that can be pinched to peel the fruit. Inside the fruit are three edible lobes, which resemble and have the consistency of peeled garlic cloves. The taste is usually sweet and acidic, with a strong astringent edge.

Nativity is a devotional mid-1450s oil-on-wood and art panel painting by the Early Netherlandish painter Petrus Christus. It shows a nativity scene—the birth of the Christ Child as narrated in the Gospels of Matthew and Luke—with grisaille archways and trompe-l'œil sculptured reliefs. The panel, which may have once been part of a triptych, was acquired by Andrew Mellon in the 1930s. One of several hundred works from Mellon's personal collection donated to the National Gallery of Art in Washington, Nativity was restored in the early 1990s.

Fatoumata Diawara (b. 1982) is a Malian musician and actress. Born in Ivory Coast, she moved to France to pursue acting, eventually appearing in films such as La genèse and Sia, le rêve du python. She later took up the guitar and began composing her own material, writing songs that blend Wassoulou traditions of southern Mali with international influences. Diawara's debut album, Fatou (2011), was named 2011's best world music album by The Sunday Times. Since 2014, she has collaborated extensively with the Cuban jazz pianist Roberto Fonseca.

Louis Pasteur (1822–1895) was a French chemist and microbiologist renowned for his discoveries of the principles of vaccination, microbial fermentation, and pasteurization. He reduced mortality from puerperal fever, and created the first vaccines for rabies and anthrax. His medical discoveries provided direct support for the germ theory of disease and its application in clinical medicine. Together with Ferdinand Cohn and Robert Koch, he is regarded as one of the main founders of bacteriology.

An Old Man and his Grandson is a tempera painting by the Italian Renaissance artist Domenico Ghirlandaio completed c. 1490. It portrays an older man in a red robe, embracing a young child whose hand is on his chest. The deformity of the man's nose, evidence of rhinophyma, is at variance with the physiognomic theory of the era, as it is seen not as implying a defect of character but as inviting an appreciation of the man's virtuousness. Critics have noted an emotional undercurrent in the work; according to art historian Bernard Berenson, "There is no more human picture in the entire range of Quattrocento painting, whether in or out of Italy."
