Mohammad Abdus Salam [4] [5] [6] NI(M) SPk (/ s æ ˈ l æ m /; pronounced [əbd̪ʊs səlaːm]; 29 January 1926 – 21 November 1996) [7] was a Pakistani theoretical physicist.He shared the 1979 Nobel Prize in Physics with Sheldon Glashow and Steven Weinberg for his contribution to the electroweak unification theory.

Physics is also called " the fundamental science" because all branches of natural science like chemistry, astronomy, geology, and biology are constrained by laws of physics. [ 59 ] Similarly, chemistry is often called the central science because of its role in linking the physical sciences.
Fundamental interaction. In physics, the fundamental interactions or fundamental forces are the interactions that do not appear to be reducible to more basic interactions. There are four fundamental interactions known to exist in nature: [1] gravity. electromagnetism.
Fifth force. In physics, there are four observed fundamental interactions (also known as fundamental forces) that form the basis of all known interactions in nature: gravitational, electromagnetic, strong nuclear, and weak nuclear forces. Some speculative theories have proposed a fifth force to explain various anomalous observations that do not ...
Matter is a general term describing any 'physical substance'. By contrast, mass is not a substance but rather a quantitative property of matter and other substances or systems; various types of mass are defined within physics – including but not limited to rest mass, inertial mass, relativistic mass, mass–energy.
Physics – natural science that involves the study of matter [1] and its motion through spacetime, along with related concepts such as energy and force. [2] More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves. [3][4][5]
Inertia is the natural tendency of objects in motion to stay in motion and objects at rest to stay at rest, unless a force causes its speed or direction to change. It is one of the fundamental principles in classical physics, and described by Isaac Newton in his first law of motion (also known as The Principle of Inertia). [1]
The popular culture of the time accordingly often depicted it as a mysterious, quasi-magical force that can slay the living, revive the dead or otherwise bend the laws of nature. [ 100 ] : 69 This attitude began with the 1771 experiments of Luigi Galvani in which the legs of dead frogs were shown to twitch on application of animal electricity .
