Cornell University is a private Ivy League statutory land-grant research university based in Ithaca, New York. Founded in 1865 by Ezra Cornell and Andrew Dickson White, Cornell was founded with the intention to teach and make contributions in all fields of knowledge – from the classics to the sciences, and from the theoretical to the applied. These ideals are captured in Cornell's founding principle, an 1868 quotation from founder Ezra Cornell:I would found an institution where any person can find instruction in any study.

A Doctor of Philosophy is the most common degree at the highest academic level awarded following a course of study and research. PhDs are awarded for programs across the whole breadth of academic fields. Because it is an earned research degree, those studying for a PhD are required to produce original research that expands the boundaries of knowledge, normally in the form of a dissertation, and defend their work before a panel of other experts in the field. The completion of a PhD is often a requirement for employment as a university professor, researcher, or scientist in many fields. Individuals who have earned a Doctor of Philosophy degree use the title Doctor with their name, although the proper etiquette associated with this usage may also be subject to the professional ethics of their own scholarly field, culture, or society. Those who teach at universities or work in academic, educational, or research fields are usually addressed by this title "professionally and socially in a salutation or conversation." Alternatively, holders may use post-nominal letters such as "Ph.D.", "PhD", or "DPhil". It is, however, considered incorrect to use both the title and post-nominals at the same time.

The Vinland Map was claimed to be a 15th-century mappa mundi with unique information about Norse exploration of North America but is now known to be a 20th-century forgery. The map first came to light in 1957 and was acquired by Yale University. It became well known due to the publicity campaign which accompanied its revelation to the public as a "genuine" pre-Columbian map in 1965. In addition to showing Africa, Asia and Europe, the map depicts a landmass south-west of Greenland in the Atlantic labelled as Vinland.

A mappa mundi is any medieval European map of the world. Such maps range in size and complexity from simple schematic maps 25 millimetres or less across to elaborate wall maps, the largest of which to survive to modern times, the Ebstorf map, was around 3.5 m in diameter. The term derives from the Medieval Latin words mappa and mundus (world).

The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about 106,460,000 km2 (41,100,000 sq mi). It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the "Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World.

Greenland's capital is Nuuk.

Vinland, Vineland, or Winland (Old Norse: Vínland ᚠᛁᚾᛚᛅᚾᛏ, ᛟᚱ ᚠᛁᚾᛖᛚᚨᚾᛞ᛫ was an area of coastal North America explored by Vikings. Leif Erikson landed there around 1000 AD, nearly five centuries before the voyages of Christopher Columbus and John Cabot. The name appears in the Vinland Sagas, and describes Newfoundland and the Gulf of Saint Lawrence as far as northeastern New Brunswick. Much of the geographical content of the sagas corresponds to present-day knowledge of transatlantic travel and North America.

His expeditions were the first known European contact with the Caribbean, Central America, and South America.

Anatase is a metastable mineral form of titanium dioxide (TiO2) with a tetragonal crystal structure. Although colorless or white when pure, anatase in nature is usually a black solid due to impurities. Three other polymorphs (or mineral forms) of titanium dioxide are known to occur naturally: brookite, akaogiite, and rutile, with rutile being the most common and most stable of the bunch. Anatase is formed at relatively low temperatures and found in minor concentrations in igneous and metamorphic rocks. Thin films of TiO2-coated glass show antifogging and self-cleaning properties under ultraviolet radiation.

Titanium dioxide, also known as titanium(IV) oxide or titania, is the inorganic compound with the chemical formula TiO2. When used as a pigment, it is called titanium white, Pigment White 6 (PW6), or CI 77891. It is a white solid that is insoluble to water, although mineral forms can appear black. As a pigment, it has a wide range of applications, including paint, sunscreen, and food coloring. When used as a food coloring, it has E number E171. World production in 2014 exceeded 9 million tonnes. It has been estimated that titanium dioxide is used in two-thirds of all pigments, and pigments based on the oxide have been valued at a price of $13.2 billion.

Anastasio Alberto Ballestrero - in religious Anastasio del Santissimo Rosario - was an Italian Roman Catholic cardinal and professed member from the Discalced Carmelites who served as the Archbishop of Turin from 1977 until his resignation in 1989. Ballestrero was elevated to the cardinalate in 1979 and became a leading progressive voice in the Italian episcopate during his time as the head of the Italian Episcopal Conference in the pontificate of the conservative Pope John Paul II. Ballestrero likewise was known for being reserved when it came to the Shroud of Turin as opposed to the enthusiasm of John Paul II for the relic. The cardinal allowed for testing of the shroud and announced that the relic itself was a product of the Middle Ages as opposed to the genuine burial cloth of Jesus Christ.

Polarized light microscopy can mean any of a number of optical microscopy techniques involving polarized light. Simple techniques include illumination of the sample with polarized light. Directly transmitted light can, optionally, be blocked with a polariser orientated at 90 degrees to the illumination. More complex microscopy techniques which take advantage of polarized light include differential interference contrast microscopy and interference reflection microscopy. Scientists will often use a device called a polarizing plate to convert natural light into polarized light.

The Supreme Court of the United States (SCOTUS) is the highest court in the federal judiciary of the United States. It has ultimate appellate jurisdiction over all U.S. federal court cases, and over state court cases that involve a point of U.S. Constitutional or federal law. It also has original jurisdiction over a narrow range of cases, specifically "all Cases affecting Ambassadors, other public Ministers and Consuls, and those in which a State shall be Party." The court holds the power of judicial review, the ability to invalidate a statute for violating a provision of the Constitution. It is also able to strike down presidential directives for violating either the Constitution or statutory law. However, it may act only within the context of a case in an area of law over which it has jurisdiction. The court may decide cases having political overtones, but has ruled that it does not have power to decide non-justiciable political questions.

Ludwig van Beethoven was a German composer and pianist. Beethoven remains one of the most admired composers in the history of Western music; his works rank amongst the most performed of the classical music repertoire and span the transition from the Classical period to the Romantic era in classical music. His career has conventionally been divided into early, middle, and late periods. His early period, during which he forged his craft, is typically considered to have lasted until 1802. From 1802 to around 1812, his middle period showed an individual development from the styles of Joseph Haydn and Wolfgang Amadeus Mozart, and is sometimes characterized as heroic. During this time, he began to grow increasingly deaf. In his late period, from 1812 to 1827, he extended his innovations in musical form and expression.

Lead poisoning, also known as plumbism and saturnism, is a type of metal poisoning caused by lead in the body. The brain is the most sensitive. Symptoms may include abdominal pain, constipation, headaches, irritability, memory problems, infertility, and tingling in the hands and feet.
