Codes - how to make them and break them - Kjartan Poskitt

Will show readers how to encode/decode their own messages in as manyways as possible.Examples of differently coded messages will also fit in well withthe diverse range of the usual MM charactersContents would include: Disguised codes (e.g. see the last para of synopsis) Scrambled codes (where the order of letters is mixed up) Substitution codes (where letters are replaced by other lettersor symbols or just 14 21 13 2 5 18 19 Some history of how codes have been used in the past, from ancientRoman times to cracking the WW2 German Enigma machine. Other message systems such as morse code, flags and also activityideas such as making cut-out stencils that work with code grids.Although the other MM books deliberately avoid exercises or settingquestions, this title lends itself to setting messages that needdecoding by the reader, possibly leading up to a mega messageto decode at the end.Can you see this very last paragraph is coded? (Read all the fourthwords). The book demonstrates other codes you've probably neverreally been aware of. Stop waiting therefore and go for it.
