Gauthier, N. – International Journal of Mathematical Education in Science and Technology, 2005
The equation of motion for a mass that moves under the influence of a central, inverse-square force is formulated and solved as a problem in complex variables. To find the solution, the constancy of angular momentum is first established using complex variables. Next, the complex position coordinate and complex velocity of the particle are assumed…

Caron, Daniel W.; Fuller, Jeremy; Watson, Janice; St. Hilaire, Katherine – National Aeronautics and Space Administration (NASA), 2007
In May 2005, the International Technology Education Association (ITEA) was funded by the National Aeronautics and Space Administration (NASA) to develop curricular units for Grades K-12 on Space Exploration. The units focus on aspects of the themes that NASA Engineers and Scientists--as well as future generations of explorers--must consider, such…
