Acknowledgments:Thanks to all who worked on the concept andproduction of this unique engagement calendar;especially Dennis Thurlow of TAB Books for dates,Patty Walsh for art and design, and Emil Krausefor his editorial assistance.

About the authorJack EidswickJack Eidswick, a Mathematics Professor at theUniversity of Nebraska has devised numerousgeometric puzzles with the Rubik Cube and is theauthor of "Rubik's Cube Made Easy,*". which isthe first solution book that explains themathematics behind the cube.
