In the book “Charlie Thorne and The Last Equation” Einsteins most complex equation is called “Pandora” which is an allusion to Pandora‘s Box. Einstein calls this equation Pandora because of how his curiosity led him to creating something that can either cause mass destruction or solve world hunger forever, much like Pandora, whose curiosity led her to unleashing curses onto mankind by opening a box.

In the Book title “Charlie Thorne and the Last Equation”, the word “Last” is a denotation because it specificallyconnects to the main conflict in the book, because of the way Charlie is depended upon to save the world from being destroyed by Pandora, the last equation Albert Einstein has ever solved.
