Westernisation, a concept notably developed by M.N. Srinivas, refers to the changes in Indian society and culture resulting from contact with the West, particularly during British colonial rule. This process involves the adoption of Western technology, institutions, ideologies, and values, which fundamentally altered traditional Indian social structures, legal systems, and educational frameworks over the course of the colonial period.

In sociology, an invention is defined as the creation of a new product, process, or idea by combining existing knowledge or materials in a novel way. This is distinct from a discovery, which involves finding something that already exists but was previously unknown or unrecognized.

Material inventions refer to physical objects or technologies, whereas social inventions refer to new ways of organizing human behavior, social relationships, or governance. A democratic government is a complex system of laws, norms, and institutions designed to organize political power and social participation. Therefore, it is classified as a social invention rather than a physical or material tool.

Cultural imperialism refers to the process by which a dominant culture imposes its values, beliefs, and media products on other societies. The widespread consumption of American films globally is a primary example used to illustrate how dominant nations can influence the cultural landscape of others, potentially eroding local traditions and perspectives through media hegemony.

A discovery involves uncovering or gaining knowledge about something that already exists in the natural world but was previously unknown to humans. Since the moon of Saturn existed before its observation, identifying it constitutes a discovery rather than an invention, which involves creating something new.

Adaptation refers to the process by which a culture modifies its practices, beliefs, or structures to survive and maintain stability in response to changing environmental or social conditions. This allows the society to preserve its core functions while adjusting to new challenges or pressures.

Ogburn's theory of cultural lag and social change suggests that a single invention can have multiple, far-reaching effects on society. Both the radio and the automobile are classic examples of this; they did not just change transportation or communication, but fundamentally altered family structures, urban development, leisure activities, and economic patterns across the entire social landscape.

Many great civilizations, such as ancient Egypt, Mesopotamia, and China, developed in low-lying areas near rivers. These regions provided fertile soil for agriculture, reliable water sources for irrigation, and natural transportation routes, which collectively facilitated trade, population growth, and the development of complex cultural and political systems.

Cultural innovation typically occurs through discovery, which involves finding something that already exists, and invention or innovation, which involves creating something new by combining existing elements in a novel way. Both processes drive cultural change.

Culture shock is the feeling of disorientation, anxiety, or stress that occurs when an individual is suddenly exposed to a new, unfamiliar culture or a rapid shift in their own cultural environment. It arises because the individual's familiar social cues and norms are no longer effective, requiring significant psychological adjustment to navigate the new social reality successfully.
