Uncertainty refers to epistemic situations involving imperfect or unknown information. It applies to predictions of future events, to physical measurements that are already made, or to the unknown. Uncertainty arises in partially observable and/or stochastic environments, as well as due to ignorance, indolence, or both. It arises in any number of fields, including insurance, philosophy, physics, statistics, economics, finance, psychology, sociology, engineering, metrology, meteorology, ecology and information science.
An undergraduate degree (also called first degree or simply degree) is a colloquial term for an academic degree earned by a person who has completed undergraduate courses. In the United States, it is usually offered at an institution of higher education, such as a college or university. The most common type of these undergraduate degrees are associate’s degree and bachelor’s degree. Bachelor’s degree typically takes at least three or four years to complete. In some other educational systems, undergraduate education is post-secondary education up to the level of a master’s degree; this is the case for some science courses in Britain and some long-cycle medicine courses in Europe. These degrees can be categorised as basic or first professional degrees.
Undergraduate education is education conducted after secondary education and prior to postgraduate education. It typically includes all postsecondary programs up to the level of a bachelor’s degree. For example, in the United States, an entry-level university student is known as an undergraduate, while students of higher degrees are known as graduate students. In some other educational systems, undergraduate education is postsecondary education up to the level of a master’s degree; this is the case for some science courses in Britain and some medicine courses in Europe.
Unemployment, according to the OECD (Organisation for Economic Co-operation and Development), is persons above a specified age (usually 15) not being in paid employment or self-employment but currently available for work during the reference period.
The universe (Latin: universus) is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy. The Big Bang theory is the prevailing cosmological description of the development of the universe. According to estimation of this theory, space and time emerged together 13.799±0.021 billion years ago, and the universe has been expanding ever since. While the spatial size of the entire universe is unknown, it is possible to measure the size of the observable universe, which is currently estimated to be 93 billion light-years in diameter. In various multiverse hypotheses, a universe is one of many causally disconnected constituent parts of a larger multiverse, which itself comprises all of space and time and its contents; as a consequence, ‘the universe’ and ‘the multiverse’ are synonymous in such theories.

A university (Latin: universitas, ‘a whole’) is an institution of higher (or tertiary) education and research which awards academic degrees in various academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, universities must offer graduate degrees; institutions offering only undergraduate degrees are colleges.
The word university is derived from the Latin universitas magistrorum et scholarium, which roughly means “community of teachers and scholars”.
The first universities were created in Europe by Christian monks. The University of Bologna (Università di Bologna), founded in 1088, is the first university in the sense of:
high degree-awarding institute;
independence from the ecclesiastic schools, although conducted by both clergy and non-clergy;
the word universitas was coined at its foundation;
secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law
The medieval universities created in Italy evolved from cathedral schools for the clergy during the High Middle Ages.
Urban planning, also known as regional planning, town planning, city planning, or rural planning, is a technical and political process that is focused on the development and design of land use and the built environment, including air, water, and the infrastructure passing into and out of urban areas, such as transportation, communications, and distribution networks and their accessibility. Traditionally, urban planning followed a top-down approach in master planning the physical layout of human settlements. The primary concern was the public welfare, which included considerations of efficiency, sanitation, protection and use of the environment, as well as effects of the master plans on the social and economic activities. Over time, urban planning has adopted a focus on the social and environmental bottom-lines that focus on planning as a tool to improve the health and well-being of people while maintaining sustainability standards. Sustainable development was added as one of the main goals of all planning endeavors in the late 20th century when the detrimental economic and the environmental impacts of the previous models of planning had become apparent. Similarly, in the early 21st century, Jane Jacob’s writings on legal and political perspectives to emphasize the interests of residents, businesses and communities effectively influenced urban planners to take into broader consideration of resident experiences and needs while planning.
