 \subsection*{Who was Voltaire?}
 \emph{Mr. Voltaire} was in fact \emph{Francois-Marie Arouet} who supported Newton's laws by own means. He thought if Newton can find a rational explanation for the universe, Voltaire could find a rational explanation for the things going on on earth. e.g. the demanded obedience of the king, Aristocrats who got authority from the king which nobody is allowed to question this, the role of money, or other hidden forces in politics. After Francois returned from Paris, three years after that he pushed those ideas. Due to his writings the name Voltaire got more known than \emph{Arouet}. The next thing he wanted to do was to find a place where he can put the seeds of his studies, as it would not be possible to change the nation at once. Which was Emilie du Chatelet.
