In the philosophy of logical positivism, the doctrine holding that all sciences share the same language, laws, and method. The unity of language has been taken to mean either that all scientific statements could be restated as a set of protocol sentences describing sense-data or that all scientific terms could be defined using physics terms. The unity of law means that the laws of the various sciences must be deduced from some set of fundamental laws (e.g., those of physics). The unity of method means that the procedures for supporting statements in the various sciences are basically the same. The unity-of-science movement that arose in the Vienna Circle held to those three unities, and Rudolf Carnap's “physicalism” supported the notion that all the terms and statements of empirical science could be reduced to terms and statements in the language of physics.

Attempt to describe all fundamental interactions between elementary particles in terms of a single theoretical framework (a “theory of everything”) based on quantum field theory. So far, the weak force and the electromagnetic force have been successfully united in electroweak theory, and the strong force is described by a similar quantum field theory called quantum chromodynamics. However, attempts to unite the strong and electroweak theories in a grand unified theory have failed, as have attempts at a self-consistent quantum field theory of gravitation.

ANNISU (Unified) was formed on September 25 2002, through the merger of the All Nepal National Independent Students Union (Sixth) (students wing of Communist Party of Nepal (Unity Centre)) and All Nepal National Independent Students Union (2022) (students wing of Communist Party of Nepal (Masal)). The founding of the ANNISU (United) occurred in the period of unification of CPN (Unity Centre) and CPN (Masal).
The founding conference of ANNISU (Unified) elected a 42 member ad hoc committee to lead the organisation. As of 2002 Krishna Adhikari was the president of ANNISU (Unified) and Prakash Pokharel was the general secretary of the organisation.
ANNISU (Unified) actively took part in the protests against the royal regime in Nepal.
