               The English scientist Sir Isaac Newton
          (1643–1727) used a lot of BRAINY MATH
           to explain how the world worked. Among
               other things, he developed the theory
                  of gravity and was the first person
              to explain exactly what makes objects
                 move. Newton’s ideas, known as his
             “laws,” are still taught to students today.



             How it changed
                 When Newton figured
                   out scientific laws
              explaining how the Universe
                operated, he paved the
                way for wonders such
                           the world
                   as space travel.




         Newton wrote a very
         famous book, called                                                                           A falling apple
         The Principles of                                                                             may have inspired
         Natural Philosophy.                                                                           Newton’s thoughts

                                                                                                       on gravity.












                        Reaction
                          Action




                                                 Newton’s mother wanted him to be a farmer!



       The three laws
       Newton’s laws of motion
       explain how forces move
       objects and affect their
       direction, speed, and                      Newton’s laws
       distance traveled. The
       THIRD LAW says that                        of motion
       for each action there is
       a reaction. For example,
       if an object is pushed                     Mathematical discoveries that form
       upward it will exert an
       equal push downward.                       the basis of modern SCIENCE
