MAKING A DIFFERENCE
Codes and ciphers are really starting to make a positive difference around the world. Almost every day, one saves lives. For example, Braille is helping millions of blind citizens around the world read books. Sign language make a difference by helping the deaf talk. Even French, Japanese, English, and Chinese are examples of codes that help us communicate.
Stop signs, yield, one way, or pedestrian crossings. Do they all sound familiar? Of course. They are some of the many codes and ciphers that help you drive safely. They help people by telling us when to stop or when to slow down so two cars wont crash into each other.
