The Book...The Movie...Yes, the Movie!
For years (42 years to be more specific), mathematics teachers (K-16) have shared this quirky book with their students. Originally published in 1963 and now a classic, The Dot and the Line: A Romance in Lower Mathematics was written by Norman Juster (also the author of The Phantom Tollbooth). Using only the colors black and red, the book is a "poignant yet humorous" story about a straight line who has fallen in love with a red dot who has fallen in love with a rebellious squiggle, and the straight line's attempts to woo the dot's attention away from the squiggle. You will have to read the book to see if the hero gets his girl....includes an amusing analogy involving a vector.
Fortunately, a new reprint of the The Dot and the Line: A Romance in Lower Mathematics is available for purchase on-line and at bookstores everywhere...at a low price...and just in time for use by teachers on Valentine's Day. If you need to justify its use as part of a lesson plan, you might want to read Donald Mitchell's review of the book on Amazon's web site.
And after many years of sporadic searching, I have discovered a way to own a DVD of the animated cartoon version of The Dot and the Line: A Romance in Lower Mathematics. Directed by Chuck Jones, the cartoon version was released on Dec, 31 1965 by MGM, with a running time of only 10 minutes. It won an Academy Award for Best Animated Short Subject in 1966!
For some odd reason, this animated version has been included as a "Special Feature" on the DVD for the Doris Day/Rod Taylor's The Glass Bottom Boat, an inane spy movie originally issued in 1966. Search the Internet for the DVD as its prices and availability vary. This will be one time where you might never look at the main feature...only the trailer.
