Discovering works of January 2008 inspired by previous exhibits in New York and Holland. New discoveries are acquired through various senses and are usually assimilated with pre-existing knowledge and actions. Questioning is a major form of human thought and interpersonal communication, and plays a key role in discovery. Discoveries are acquired through questions. With reference to science and academic disciplines, discovery is the observation of new phenomena, new actions, or new events and providing new reasoning to explain the knowledge gathered through such observations with previously acquired knowledge from abstract thought and everyday experience. In scientific research, exploration is one of three purposes of research (the other two being description and explanation). Discovery is made by providing observational evidence and attempts to develop an initial, rough understanding of some phenomenon. Some observational discoveries lead to invention of object, process, or techniques. A discovery may sometimes be based on earlier discoveries, collaborations or ideas, and the process of discovery requires at least the awareness that an existing concept or method can be modified or transformed. However, some discoveries also represent a radical breakthrough in knowledge.
