Real lifeReal life is a phrase used originally in literature to distinguish between the real world and fictional, virtual or idealized worlds, and in acting to distinguish between actors and the characters they portray. It has become a popular term on the Internet to describe events, people, activities, and interactions occurring offline; or otherwise not primarily through the medium of the Internet. It is also used as a metaphor to distinguish life in a vocational setting as opposed to an academic one, or adulthood and the adult world as opposed to childhood or adolescence.
PtolemyClaudius Ptolemy (ˈtɒləmi; Πτολεμαῖος, ; Claudius Ptolemaeus; 100-170 AD) was an Alexandrian mathematician, astronomer, astrologer, geographer, and music theorist, who wrote about a dozen scientific treatises, three of which were of importance to later Byzantine, Islamic, and Western European science. The first is the astronomical treatise now known as the Almagest, although it was originally entitled the Mathēmatikē Syntaxis or Mathematical Treatise, and later known as The Greatest Treatise.
HeliocentrismHeliocentrism (also known as the Heliocentric model) is the astronomical model in which the Earth and planets revolve around the Sun at the center of the universe. Historically, heliocentrism was opposed to geocentrism, which placed the Earth at the center. The notion that the Earth revolves around the Sun had been proposed as early as the third century BC by Aristarchus of Samos, who had been influenced by a concept presented by Philolaus of Croton (c. 470 – 385 BC).
Scientific lawScientific laws or laws of science are statements, based on repeated experiments or observations, that describe or predict a range of natural phenomena. The term law has diverse usage in many cases (approximate, accurate, broad, or narrow) across all fields of natural science (physics, chemistry, astronomy, geoscience, biology). Laws are developed from data and can be further developed through mathematics; in all cases they are directly or indirectly based on empirical evidence.
Archival researchArchival research is a type of research which involves seeking out and extracting evidence from archival records. These records may be held either in collecting institutions, such as libraries and museums, or in the custody of the organization (whether a government body, business, family, or other agency) that originally generated or accumulated them, or in that of a successor body (transferring, or in-house archives).
Aura (paranormal)According to spiritual beliefs, an aura or energy field is a colored emanation said to enclose a human body or any animal or object. In some esoteric positions, the aura is described as a subtle body. Psychics and holistic medicine practitioners often claim to have the ability to see the size, color and type of vibration of an aura. In spiritual alternative medicine, the human being aura is seen as part of a hidden anatomy that reflects the state of being and health of a client, often understood to even comprise centers of vital force called chakras.
Historical methodHistorical method is the collection of techniques and guidelines that historians use to research and write histories of the past. Secondary sources, primary sources and material evidence such as that derived from archaeology may all be drawn on, and the historian's skill lies in identifying these sources, evaluating their relative authority, and combining their testimony appropriately in order to construct an accurate and reliable picture of past events and environments.
International studentInternational students, or foreign students, are students who undertake all or part of their tertiary education in a country other than their own and move to that country for the purpose of studying. In 2020, there were over 6.36 million international students, up from 5.12 million in 2016. The most popular destinations were the United States (with 957,475 international students), the United Kingdom (550,877 students), and Australia (458,279 students), which together receive 31% of international students.
Everyday lifeEveryday life, daily life or routine life comprises the ways in which people typically act, think, and feel on a daily basis. Everyday life may be described as mundane, routine, natural, habitual, or normal. Human diurnality means most people sleep at least part of the night and are active in daytime. Most eat two or three meals in a day. Working time (apart from shift work) mostly involves a daily schedule, beginning in the morning. This produces the daily rush hours experienced by many millions, and the drive time focused on by radio broadcasters.
ScienceScience is a rigorous, systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Modern science is typically divided into three major branches: natural sciences (e.g., biology, chemistry, and physics), which study the physical world; the social sciences (e.g., economics, psychology, and sociology), which study individuals and societies; and the formal sciences (e.g., logic, mathematics, and theoretical computer science), which study formal systems, governed by axioms and rules.
