Unified Theory of Mathematical Physics
The Unified Theory of Mathematical Physics or the Unified Field Theory is a high level branch of physics. The Unified Theory of Mathematical Physics or the Unified Field Theory attempts to explain the four fundamental forces in terms of one single unified force. The Unified Theory of Mathematical Physics is key in Particle Physics but the Unified Theory of Mathematical Physics is a very difficult branch of physics and is no way for school physics of physics for kids. We will not discuss the Unified Theory of Mathematical Physics or the Unified Field Theory beyond this introduction to physics.
The Four Fundamental Forces
The Four fundamental forces are:
 strong nuclear force
 weak nuclear force
 electromagnetic force, and
 gravity force
Origin of the Unified Theory of Mathematical Physics

The Unified Theory of Mathematical Physics or the Unified Field Theory was started by Albert Einstein. After Einstein, many physicists developed the Unified Theory of Mathematical Physics or the Unified Field Theory further. By 1971, a theory developed by Steven Weinberg, Sheldon Glashow, Abdus Salam, and a few other physicists linked the weak force and the electromagnetic force together. That was the first step to the Grand Unified Theory which in turn leads to the Theory of Everything that many great physicists yearn for. 
The Grand Unified Theory & The Theory of Everything
The Grand Unified Theory is the physics theory that combines the strong force with the electroweak force. The Grand Unified Theory of Mathematical Physics is the stepping stone towards the foundation of the Theory of Everything. When the Grand Unified Thoery incorporates gravity along with the other three fundamental forces, the Theory of Everything is at hand. Many branches of mathematics, mathematical physics, theoretical physics, cosmology, Particle physics, and other abstract branches of mathematical physics have researchers working round the clock devoting themselves to the quest. Superstring Theory is one of the many theories that attempts to explain and arrive at the Theory of Everything.
