I. Introduction

The Dark Knight, which was released in year 2008, is a movie following up Christopher Nolan’s first Batman movie in 2005, the Batman Begins. The movie is all about a billionaire boy, Bruce Wayne, who witnessed the death of his parents. He wanted to avenge in behalf them so he got himself involved in very strict trainings to make himself physically and mentally strong and ready for any possible circumstances that may occur in times of avenging his parents to the people worth punishing for. He does not only use his strength in fighting but also uses some smart, extraordinary, high-end personalized gadgets made from his wealth. The citizens of Gotham call him Batman because he wears a black full costume with cape and a bat sign on it.
In The Dark Knight, his enemy is known as The Joker, a popular antagonist that always wears a clown-looking makeup to hide his scar of carved mouth and is also popular by always wearing purple and green clothes. He has no identity but his look and his brutal but smart ways of putting people in danger. Even the NBI cannot find any references of who he is and where he comes from.
This movie is said to be the most realistic kind of an epic story and character because everything it contents can possibly happen in real life. All you need to have is money—a lot of money—and perseverance to learn and to engage into serious martial arts trainings and stuff. No necessary power or magic. So let us see how physics got in to it.
