For many years physicists have sought an equation that would explain the universe and all of its components. Every new idea that arose seemed to only cloud previous theories. The major problem was unifying quantum mechanics with Einstein's Theory of Relativity. Quantum mechanics deal with the smallestparticles such as electrons and atoms. Einstein's theory of general relativity explains how very large masses like stars and galaxies behave. String theory provides a complex insight into how small particles behave in order to produce large masses with respect to gravity and electromagnetism.

Sir Isaac Newton is a theoretical physicist who made many important discoveries. He is known for discovering calculus to explain how objects in motion work. He also utilized calculus to formulate a mathematical model for the force of gravity.1 Gravity plays an important role in string theory. It is a force that remains a mystery in many aspects...
