Superposition theorem is one of the most important ingredients in the field of physics. It is one of the four fundamental laws that govern all matter and forces in existence. The other three are E=mc^2, Newton's law of gravitation, and Maxwell's equations. The superposition theorem states that if two particles are placed at different distances from each other, their interactions will be influenced by both particles
The superposition theorem is a well-known result in combinatorics, which states that if two or more elements are added to a collection of objects, the sum of the collections is always equal to the first element.
This simple idea has been applied to data mining and machine learning problems. For example, Peter Norvig published his book "Superposition Theorem" to illustrate this idea.
