Science Communication and Public Engagement

Communication (from Latin commūnicāre, meaning "to share") is the act of conveying intended meanings from one entity or group to another through the use of mutually understood signs and semiotic rules.

An engagement, betrothal, or fiancer is a promise to wed, and also the period of time between a marriage proposal and a marriage. During this period, a couple is said to be betrothed, intended, affianced, engaged to be married, or simply engaged. Future brides and grooms may be called the betrothed, a wife-to-be or husband-to-be, fiancée or fiancé (from the French word of the same form), respectively. The duration of the courtship varies vastly, and is largely dependent on cultural norms or upon the agreement of the parties involved.

In public relations and communication science, publics are groups of individual people, and the public (a.k.a. the general public) is the totality of such groupings. This is a different concept to the sociological concept of the Öffentlichkeit or public sphere. The concept of a public has also been defined in political science, psychology, marketing, and advertising. In public relations and communication science, it is one of the more ambiguous concepts in the field. Although it has definitions in the theory of the field that have been formulated from the early 20th century onwards, it has suffered in more recent years from being blurred, as a result of conflation of the idea of a public with the notions of audience, market segment, community, constituency, and stakeholder.

Science (from Latin scientia, meaning "knowledge") is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.

Science communication is the public communication of science-related topics to non-experts. This often involves professional scientists (called "outreach" or "popularization"), but has also evolved into a professional field in its own right. It includes science exhibitions, journalism, policy or media production. Science communication also includes communication between scientists (for instance through scientific journals), as well as between scientists and non-scientists (especially during public controversies over science and in citizen science initiatives).
