The spiny-cheeked honeyeater (Acanthagenys rufogularis) is a species of bird in the family Meliphagidae, the honeyeaters, and the only species in the monotypic genus Acanthagenys. It is large for a honeyeater, ranging from 22 to 27 centimetres (8.7 to 10.6 in) in length and weighing around 52 grams (1.8 oz). A common species throughout most of Australia, the birds are sociable and aggressive, and often observed foraging in large flocks. This spiny-cheeked honeyeater was photographed near Patchewollock in the Australian state of Victoria.

Ophrys insectifera, the fly orchid, is a species of orchid and the type species of the genus Ophrys. It is remarkable as an example of the use of sexually deceptive pollination and floral mimicry, as well as a highly selective and highly evolved plant–pollinator relationship. The plants use scent that mimics female sexual pheromones to attract male wasps, which pollinate the flowers while attempting to mate with them. It is classified as a least-concern species by the International Union for Conservation of Nature, but considered to be vulnerable in Great Britain. This o. insectifera orchid was photographed in Niitvälja, Estonia.

The double-crested cormorant (Nannopterum auritum) is a member of the cormorant family of water birds. Its habitat is near rivers and lakes as well as in coastal areas, and is widely distributed across North America, from the Aleutian Islands in Alaska down to Florida and Mexico. Measuring 70 to 90 cm (28 to 35 in) in length, it is an all-black bird which gains a small double crest of black and white feathers in breeding season. It has a bare patch of orange-yellow facial skin. Five subspecies are recognized. It mainly eats fish and hunts by swimming and diving. Its feathers, like those of all cormorants, are not waterproof and it must spend time drying them out after spending time in the water. Once threatened by the use of DDT, its numbers have increased markedly in recent years. This juvenile double-crested cormorant, of the subspecies N. a. albociliatum (the Farallon cormorant), was photographed at the Sutro Baths in San Francisco, California.

The Alcázar of Segovia is a medieval castle located in the city of Segovia in Castile and León, Spain. Rising out on a rocky crag above the confluence of two rivers near the mountains of Guadarrama, it is one of the most distinctive castle-palaces in Spain by virtue of its shape, resembling the bow of a ship. The alcázar was originally built in the 11th or 12th century by the Almoravid dynasty as a fortress, but has since served as a royal palace where twenty-two kings reigned, a state prison, a royal artillery college, and a military academy. The castle overlooks a valley with the Eresma River and is a symbol of the old city of Segovia. It was declared a UNESCO World Heritage Site in 1985. Today, the alcázar is used as a museum and a military archives building since its declaration as a national archive by royal decree in 1998.

Alexander Fleming (1881–1955) was a Scottish physician and microbiologist, best known for discovering the world's first broadly effective antibiotic substance, which he named penicillin. His discovery in 1928 of what was later named benzylpenicillin (or penicillin G) from the mould Penicillium rubens is described as the "single greatest victory ever achieved over disease." For this discovery, he shared the Nobel Prize in Physiology or Medicine in 1945 with Howard Florey and Ernst Chain.

The Isaiah Scroll, designated 1QIsa^a and also known as the Great Isaiah Scroll, is one of the seven Dead Sea Scrolls that were discovered by Bedouin shepherds in 1946 from Qumran Cave 1. The scroll is written in Hebrew and contains the entire Book of Isaiah from beginning to end, apart from a few small damaged portions. It is the oldest complete copy of the Book of Isaiah, being approximately 1000 years older than the oldest Hebrew manuscripts known before the scrolls' discovery. 1QIsa^a is the only scroll from the Qumran Caves to be preserved almost in its entirety.

Nina Simone (February 21, 1933 – April 21, 2003) was an American singer, songwriter, pianist, and civil rights activist. Her music spanned styles including classical, jazz, blues, folk, R&B, gospel and pop.

The sixth of eight children born to a poor family in Tryon, North Carolina, Simone initially aspired to be a concert pianist. However, after being denied admission to the Curtis Institute of Music in Philadelphia despite a well-received audition (which she attributed to racism), she started playing piano at a nightclub in Atlantic City. She changed her name to "Nina Simone" to disguise herself from family members, having chosen to play "the devil's music" or so-called "cocktail piano". She was told in the nightclub that she would have to sing to her own accompaniment, which effectively launched her career as a jazz vocalist. She went on to record more than 40 albums between 1958 and 1974.

Louis Blanc (29 October 1811 – 6 December 1882) was a French politician and historian. He advocated for socialist reforms without revolution first, and called for the creation of job guarantees for the urban poor. Blanc coined the phrase "right to work", and his political and social ideas greatly contributed to the development of socialism in France. This photograph of Blanc was taken in 1848 by the French photographer Étienne Carjat.

The Holmdel Horn Antenna is a large microwave horn antenna that was used as a satellite communication antenna and radio telescope during the 1960s at Bell Telephone Laboratories in Holmdel Township, New Jersey, United States. It was designated a National Historic Landmark in 1988 because of its association with the research work of two radio astronomers, Arno Penzias and Robert Wilson, who used it to discover the cosmic microwave background radiation (CMBR) that permeates the universe. This helped change the science of cosmology, the study of the history of the universe, from a field for unlimited theoretical speculation into a discipline of direct observation. In 1978, Penzias and Wilson received the Nobel Prize in Physics for their discovery.

The Old Royal Naval College is the architectural centrepiece of Maritime Greenwich, a World Heritage Site in Greenwich, London, described by the United Nations Educational, Scientific and Cultural Organization as the "finest and most dramatically sited architectural and landscape ensemble in the British Isles". The buildings were originally constructed to serve as the Royal Hospital for Seamen at Greenwich, now generally known as Greenwich Hospital, which was chartered by King William III and Queen Mary II on 25 October 1694, designed by Christopher Wren, and built between 1696 and 1712. The hospital closed in 1869. Between 1873 and 1998 it housed the Royal Naval College, Greenwich. This panoramic photograph depicts the two buildings of the Old Royal Naval College viewed from across the River Thames, with the Queen's House visible in the background in between.

Orpheus in the Underworld is a comic opera composed by Jacques Offenbach with a French-language libretto by Hector Crémieux and Ludovic Halévy. It was first performed as a two-act opéra bouffon at the Théâtre des Bouffes-Parisiens, Paris, in 1858, and was extensively revised and expanded in a four-act opéra féerie version, presented at the Théâtre de la Gaîté in 1874. The plot is a lampoon of the myth of Orpheus and Eurydice in Greek mythology. In this version, Orpheus is not the son of Apollo but a rustic violin teacher. He is glad to be rid of his wife Eurydice when she is abducted by Pluto, the god of the underworld. Orpheus has to be bullied by Public Opinion into trying to rescue Eurydice. The reprehensible conduct of the gods of Olympus in the opera was widely seen as a veiled satire of the court and government of French emperor Napoleon III. This photograph depicts Jeanne Granier as Eurydice and Eugène Vauthier as Jupiter in the form of a fly as part of the 1887 Paris revival of Orpheus in the Underworld.

Woodpeckers are a group of birds in the family Picidae, which also includes the piculets, wrynecks, and sapsuckers. Members of this family are found worldwide, except for Australia, New Guinea, New Zealand, Madagascar, and the extreme polar regions. Most species live in forests or woodland habitats, although a few species are known that live in treeless areas, such as rocky hillsides and deserts, and the Gila woodpecker specialises in exploiting cacti. This photograph shows a female campo flicker (Colaptes campestris), a woodpecker species native to South America, in the Pantanal, Brazil.

Isambard Kingdom Brunel (1806–1859) was an English civil and mechanical engineer. The son of French engineer Marc Isambard Brunel, he worked under his father as an assistant engineer on the Thames Tunnel project for several years until he was seriously injured in a flooding incident. During his recuperation he began a design for a bridge in Bristol, which would later be completed as the Clifton Suspension Bridge. In 1833, Brunel was appointed chief engineer of the Great Western Railway, overseeing development of the main line from London to Bristol which was completed in 1841. Brunel's other achievements included the design of the first transatlantic steamship and dockyards. This 1857 photograph, titled Isambard Kingdom Brunel Standing Before the Launching Chains of the Great Eastern, was taken by Robert Howlett. It depicts Brunel standing before a drum of chain used during the launching of SS Great Eastern at Millwall in London; he carries a cigar case, and his boots and trousers are muddy.

Ruth Bader Ginsburg (March 15, 1933 – September 18, 2020) was an American lawyer and jurist who served as an associate justice of the Supreme Court of the United States from 1993 until her death in 2020. She was nominated to the Supreme Court by President Bill Clinton to replace retiring justice Byron White, and at the time was generally viewed as a moderate consensus-builder. She eventually became part of the liberal wing of the Supreme Court as the Court shifted to the right over time. Ginsburg was the first Jewish woman and the second woman to serve on the Supreme Court, after Sandra Day O'Connor. During her tenure, Ginsburg wrote notable majority opinions, including United States v. Virginia (1996), Olmstead v. L.C. (1999), Friends of the Earth, Inc. v. Laidlaw Environmental Services, Inc. (2000), and City of Sherrill v. Oneida Indian Nation of New York (2005). This official photographic portrait of Ginsburg was taken by Supreme Court photographer Steve Petteway in 2016.

Leonhard Euler (15 April 1707 – 18 September 1783) was a Swiss mathematician, physicist, astronomer, geographer, logician and engineer. He founded the studies of graph theory and topology, and made pioneering and influential discoveries in many other branches of mathematics such as analytic number theory, complex analysis and infinitesimal calculus. Euler introduced much of modern mathematical notation and terminology, including the notion of a mathematical function. He is also known for his work in mechanics, fluid dynamics, optics, astronomy and music theory. This pastel-on-paper portrait of Euler was painted by the Swiss painter Jakob Emanuel Handmann in 1753, and is now in the collection of the Kunstmuseum Basel.

Joseph Fourier (21 March 1768 – 16 May 1830) was a French mathematician and physicist born in Auxerre and best known for initiating the investigation of Fourier series, which eventually developed into Fourier analysis and harmonic analysis, and their applications to problems of heat transfer and vibration. The Fourier transform and Fourier's law of conduction are also named after him. He is also generally credited with the discovery of the greenhouse effect. This engraving of Fourier was drawn by Julien-Léopold Boilly, a French artist noted for his album of lithographs titled Iconographie de l'Institut Royal de France (1820–1821) and his booklet Album de 73 portraits-charge aquarellés des membres de l'Institut (1820), containing watercolor caricatures of seventy-three members of the Institut de France.

The Divje Babe flute, also sometimes called the tidldibab or Neanderthal flute, is the femur of a cave bear, which is pierced by spaced holes similar to those found on a flute. The object was unearthed at Divje Babe I, a cave site near Cerkno in northwestern Slovenia in 1995, during systematic archaeological excavations in the area. It is possible that it was made by Neanderthals as a form of musical instrument, although this theory is debated by scientists: some argue that the holes in the bone were artificially made by Neanderthals, while others say they were made by carnivores. If confirmed as a musical instrument, it would be the oldest-known Paleolithic flute and musical instrument. The object is now in the collection of the National Museum of Slovenia in Ljubljana.

Ernest Rutherford (1871–1937) was a New Zealand physicist who was a pioneering researcher in both atomic and nuclear physics. In early work, Rutherford discovered the concept of radioactive half-life, the radioactive element radon, and differentiated and named alpha and beta radiation. This work formed the basis for a Nobel Prize in Chemistry, awarded in 1908. With Thomas Royds, Rutherford developed the theory that alpha radiation is helium nuclei, and also theorized that atoms have their charge concentrated in a very small nucleus, and thereby pioneered the Rutherford model of the atom. He went on to perform the first artificially induced nuclear reaction in 1917 in experiments where nitrogen nuclei were bombarded with alpha particles. As a result, he discovered the emission of a subatomic particle which became known as the proton. Rutherford spent his later years as director of the Cavendish Laboratory in Cambridge. The chemical element rutherfordium was named after him in 1997. This photograph of Rutherford, published by the Bain News Service, was most likely taken in the 1920s.
