The Immovable Ladder is a wooden ladder leaning against the right window on the second tier of the facade of the Church of the Holy Sepulchre in the Old City of Jerusalem. The ladder rests on a ledge and is attached to a window owned by the Armenian Apostolic Church. The ladder is a symbol of inter-confessional disputes within Christianity. Its presence in its current location signifies the adherence to an agreement among six Christian denominations, who collectively own the church, not to move, repair, or alter anything in the church without the consent of all six denominations.

Abu Rayhan al-Biruni (973 – after 1050) was a Persian scholar and polymath. He was from Khwarazm – a region which encompasses modern-day western Uzbekistan, and northern Turkmenistan.

Al-Biruni was well versed in physics, mathematics, astronomy, and natural sciences, and also distinguished himself as a historian, chronologist and linguist. He studied almost all fields of science and was compensated for his research and strenuous work. Royalty and powerful members of society sought out Al-Biruni to conduct research and study to uncover certain findings. He lived during the Islamic Golden Age. In addition to this type of influence, Al-Biruni was also influenced by other nations, such as the Greeks, who he took inspiration from when he turned to studies of philosophy. He was conversant in Khwarezmian, Persian, Arabic, Sanskrit, and also knew Greek, Hebrew and Syriac. He spent much of his life in Ghazni, then capital of the Ghaznavid dynasty, in modern-day central-eastern Afghanistan. In 1017 he travelled to the Indian subcontinent and authored a study of Indian culture Tārīkh al-Hind (History of India) after exploring the Hindu faith practiced in India. He was given the title "founder of Indology". He was an impartial writer on customs and creeds of various nations, and was given the title al-Ustadh ("The Master") for his remarkable description of early 11th-century India.

The Kirkbride Plan was a system of mental asylum design advocated by American psychiatrist Thomas Story Kirkbride (1809–1883) in the mid-19th century. The asylums built in the Kirkbride design, often referred to as Kirkbride Buildings (or simply Kirkbrides), were constructed during the mid-to-late-19th century in the United States. The structural features of the hospitals as designated by Kirkbride were contingent on his theories regarding the healing of the mentally ill, in which environment and exposure to natural light and air circulation were crucial. The hospitals built according to the Kirkbride Plan would adopt various architectural styles, but had in common the "bat wing" style floor plan, housing numerous wings that sprawl outward from the center.

The first hospital designed under the Kirkbride Plan was the Trenton State Hospital in Trenton, New Jersey, constructed in 1848. Throughout the remainder of the nineteenth century, numerous psychiatric hospitals were designed under the Kirkbride Plan across the United States. By the twentieth century, popularity of the design had waned, largely due to the economic pressures of maintaining the immense facilities, as well as contestation of Kirkbride's theories amongst the medical community.

Numerous Kirkbride structures still exist, though many have been demolished or partially-demolished and repurposed. At least 30 of the original Kirkbride buildings have been registered with the National Register of Historic Places in the United States, either directly or through their location on hospital campuses or in historic districts.

Maryam Mirzakhani (Persian: مریم میرزاخانی‎, pronounced [mæɾˈjæm miːɾzɑːxɑːˈniː]; 12 May 1977 – 14 July 2017) was an Iranian mathematician and a professor of mathematics at Stanford University. Her research topics included Teichmüller theory, hyperbolic geometry, ergodic theory, and symplectic geometry. In 2005, as a result of her research, she was honored in Popular Science's fourth annual "Brilliant 10" in which she was acknowledged as one of the top 10 young minds who have pushed their fields in innovative directions.

On 13 August 2014, Mirzakhani was honored with the Fields Medal, the most prestigious award in mathematics. Thus, she became both the first, and to date, the only woman and the first Iranian to be honored with the award. The award committee cited her work in "the dynamics and geometry of Riemann surfaces and their moduli spaces".

On 14 July 2017, Mirzakhani died of breast cancer at the age of 40.

The Battle of Athens (sometimes called the McMinn County War) was a rebellion led by citizens in Athens and Etowah, Tennessee, United States, against the local government in August 1946. The citizens, including some World War II veterans, accused the local officials of predatory policing, police brutality, political corruption, and voter intimidation.

The term 3-6-3 Rule describes how the United States retail banking industry operated from the 1950s to the 1980s. The name 3-6-3 refers to the impression that bankers had a stable, comfortable existence by paying 3 percent interest on deposits, lending money out at 6 percent, and being able to "tee off at the golf course by 3 p.m."

The implication was that the banks were less competitive during that period than in subsequent years due to tight regulations that limited the formation and location of banks as well as restrictions on interest rates that could be charged or paid. As a result, bankers had "power and prestige ... while profits were steady and certain". These regulations were loosened in the 1980s.

Richmond Federal Reserve senior economist John R. Walter argues that, although there is evidence that restrictions on banks before the 1980s did limit the competitiveness of banking markets and thereby granted some banks monopoly power, "the regulatory restrictions probably had a limited effect on competition" during the time in question. Chicago Federal Reserve researchers Robert DeYoung and Tara Rice argue that, "Like most good jokes, the 3-6-3 rule mixes a grain of truth with a highly simplified view of reality."

The rule has been noted positively following the late-2000s financial crisis as a preferable way for banks to operate following the bailout of major banks.

Australia's banking system, which was deregulated in the 1990s in a manner similar to that in the U.S., also came to be characterized in the same way as did the United Kingdom's.
