Can TJ build a working rocket in time for the science fair?

TJ Overcame His Fear of cats in TJ and the Cats and his fear of ghosts in TJ and the Haunted House. Now he's not so keen on facing his fear of failure. His best friend Seymour is determined to come up with the latest greatest invention, and TJ's gran expects TJ to build a rocket. The kittens, T-Rex and Alaska, are eager to get involved. When the first rocket that TJ builds plummets out of the sky, no parachute in sight, TJ is sure that his efforts are doomed. But are they?

Rival twin brothers battle on and off the ice in this hockey classic written when GalleyCat bestselling author Stacy Juba was just 16-years-old. Discover why this compelling novel about hockey players, high school sports, sportsmanship, sibling rivalry, and families dealing with divorce has appeared on so many reading lists including Best Books for Young Teen Readers Grades 7-10 and a list produced by the Hockey Hall of Fame's Junior Education Program. Brad's twin brother T.J. has gotten himself out of the fancy prep school his father picked for him and into the public high school Brad attends. Now T.J. is a shining new star on the hockey team where Brad once held the spotlight. And he's testing his popularity with Brad's friends, eyeing Brad's girl and competing to be captain of the team. Meanwhile, the twins must also cope with problems at home, including divorcing parents and a troubled younger brother. The whole school is rooting for a big double-strength win...not knowing that their twin hockey stars are heating up the ice for a winner takes all face-off. NEW: Originally published in 1992. This new edition contains a special letter from the author and revisions for the latest generation of readers. Reviews: "Hockey fans will be attracted by the cover and held by the game descriptions, and those who like realistic fiction will appreciate the complexity of the boys' home life, with battling parents, hero-worshipping younger siblings and a father who expects too little of one twin and too much of the other. A good read for both proficient and reluctant readers." Booklist "Lots of action and emotional upheaval ensure that this will be a popular book for boys as well as girls. This reviewer's YA Book Review Group gave it nine points out of a possible ten for 'Good Read' status." VOYA "I don’t often give a full five rating to a book I’m reviewing and especially when it’s not in a genre I usually enjoy but I have to say Face Off had me drawn in from the beginning and I read it in all one sitting. I thoroughly enjoyed it despite not being a teen and knowing nothing about ice hockey. (Although I do know a bit more about it now!)"

International Series of Monographs on Aeronautics and Astronautics, Division VII, Volume 5: The Flight of Uncontrolled Rockets focuses on external ballistics of uncontrolled rockets. The book first discusses the equations of motion of rockets. The rocket as a system of changing composition; application of solidification principle to rockets; rotational motion of rockets; and equations of motion of the center of mass of rockets are described. The text looks at the calculation of trajectory of rockets and the fundamentals of rocket dispersion. The selection further focuses on the dispersion of finned rockets. Topics include the critical section of the trajectory; standard formula for calculating angular deviation; dispersion of actual rockets; and effective launcher length. The text also describes the dispersion of finned rotated rockets and of finned anti-tank rockets. The book also examines the effect of wind on the flight of rockets. Topics include correction to the coordinates of the point of impact for finned rockets; general effect of wind on dispersion; and general treatment of powered flight in the presence of wind. The text is important for readers interested in the ballistics of uncontrolled rockets.
