(c) Self StudyA teacher will occasionally come across a bright young student who seeks to know "all about space exploration" and is willing to invest attention and time. "The Exploration of the Earth's Magnetosphere" is meant for such use: it is self-contained and nonmathematical, explicitely addressing many facets and covering related areas of physics, astronomy and history.Students with a more technical background may want to go beyond the introductory level of "Exploration." A suitable place to start is "A Brief History of Magnetospheric Physics During the Spaceflight Era" which is also included. Space scientists and graduate students, in particular, will find leads to many key articles in the extensive bibliography of that work.
(d) "Space Physics for Poets "In recent years, many undergraduate physics departments have instituted nonmathematical introductory courses for non-physics majors, sometimes whimsically titled "Physics for Poets.""Exploration" can provide the outline of a one-semester course on a similar level, which might well be called "Space Physics for Poets." A teacher presenting such a course needs a thorough command of physics and some additional familiarity with the Earth-Sun environment. The article 'A Brief History of Space Physics During the Spaceflight Era" included in these web files contains a great amount of relevant material, and more can be found in its large bibliography and in the file Additional Resources" reached from the home page of "Exploration." Teachers are also advised to look up the article "Space Physics for Poets" in The Physics Teacher, vol. 35, p. 38-9, January 1997. Happy Exploring! |
