Philosophy of science is the complex field of knowledge which intends to unite the worlds of sciences and humanities to discuss the aspects of science with references to humanities. From this point, philosophy of science aims to explain the aspects close to the field of humanities because of the necessity to provide the large theoretical background and to question points which are not important for scientists due to the lack of an empirical component. Thus, the philosophy of nursing provides the expanded theoretical background for nursing as practice, focusing on the questions of theories and methods used in the nursing practice. As a result, nursing can depend on different theories which can be rather philosophical or they can combine the aspects of science and philosophy as the theory of strings does. The PBS documentary The Elegant Universe is based on Brian Greene’s book in which the theory of strings is discussed as the “theory for everything” (The Elegant Universe, 2011). According to Greene, the paradox in science which depends on the impossibility to unite the general theory of relativity developed by Albert Einstein and the quantum mechanics can be overcome with references to the theory of strings because of its universality. Although the theory of strings is too complicated to understand it fully, and it is rather controversial, the elements of the theory can be applied to the
