The Magic of Computer Science II
The Magic of Computer Science II begins with an introduction to the resource, explaining the basic concepts used in the book. There follows descriptions of how to perform seven tricks with explanations of how the trick works and the computer science concepts illustrated in the tricks.
The joker in the pack: Uses algorithms, human-computer interaction and design to avoid human error.
Are you psychic?: The psychic powers of a member of the audience are tested. This trick uses algorithms, loops, variables and explores human-computer interaction, known as usability.
