How do you find the magnitude of the vector? I have the strength and Engle what else I nead?
where I can find this formula?
To find the length of a vector, you should have the vector of the form: P = xi + yj + zk. I, J and K are the unit vectors in space. However, the length is equal to the square root of the sum of the squares of the components x, y, z.

Sandy and Dennys interrupt their father's experiment and find themselves in the middle of a desert. They discover that they must not only find the way home, but must also reunite a man and his son--a boy named Noah. The first book in the Time Quartet.
We've all done it. In the frigid depths of winter we've wished we could be magically transported to someplace warm and sunny. But most people don't have genius parents who just happen to be working on a scientific experiment with time travel at the moment of our wish. Sandy and Dennys Murry, the "normal" boys in a family of geniuses, suddenly find themselves trudging through a blazing-hot desert, seeking a far-off oasis for shade. Their desperate wandering brings them face-to-face with history--biblical history. Soon they're feeling right at home with Noah and his family. Even so, the urgent question is, how will Sandy and Dennys get back to their own place and time before the floods--the many waters--come? As they begin to cross the invisible border into adulthood, the twins must confront their ability to resist temptation and embrace integrity. In Many Waters, Madeleine L'Engle continues the Murry family saga, which includes A Wrinkle in Time; A Wind in the Door; and A Swiftly Tilting Planet, which won the American Book Award. L'Engle's mystical mix of science fiction and fantasy, time and space travel, history, morals, religion, and culture once again urges her many adoring readers to stretch their minds and hearts to understand why the world is the way it is.

The youngest of the Murry children must travel through time and space in a battle against an evil dictator who would destroy the entire universe.
Fifteen-year-old Charles Wallace Murry, whom readers first met in A Wrinkle in Time, has a little task he must accomplish. In 24 hours, a mad dictator will destroy the universe by declaring nuclear war--unless Charles Wallace can go back in time to change one of the many Might-Have-Beens in history. In an intricately layered and suspenseful journey through time, this extraordinary young man psychically enters four different people from other eras. As he perceives through their eyes "what might have been," he begins to comprehend the cosmic significance and consequences of every living creature's actions. As he witnesses first-hand the transformation of civilization from peaceful to warring times, his very existence is threatened, but the alternative is far worse. The Murry family, also appearing in A Wind in the Door and Many Waters, acts as a carrier of Madeleine L'Engle's unique message about human responsibility for the world. Themes of good versus evil, time and space travel, and the invincibility of the human spirit predominate. Even while she entertains, L'Engle kindles the intellect, inspiring young people to ask questions of the world, and learn by challenging. (Ages 9 and older) --Emilie Coulter
