A Symplectic Integration Scheme that Allows Close Encounters between Massive Bodies J. E. Chambers, Armagh Observatory Mixed­variable symplectic integrators provide a fast, moderately accu­ rate way to study the long­term evolution of a wide variety of N­body sys­ tems (Wisdom & Holman 1991). ... A symplectic integrator works by splitting the Hamiltonian, H , for an N­body system, into two or more parts H = H 0 + H 1 + \Delta \Delta \Delta, where ffl i = H i =H 0 Ь 1 for i = 1; 2 : : :. ...

. To enter several commands on the one command line, use a ; (semicolon) to seperate each one from the next. For example: cd ..; ls -l . This command line contains two commands. The first, cd .. changes the current directory to the parent directory. The second, ls -l produces a long listing of the contents of the curent directory. If necessary you can continue the commands onto another line.

... Formulas are very similar to equations. Consider for now only equations with one unknown variable , denoted by some letter, which can be x but can also be different. An equation is an equality between two mathematical expressions containing the unknown number (maybe in several places), as well as other numbers which are known. ... For instance--if you multiply two sides of a formula by the same number, the result is still a valid formula, even if what you multiply contains unknown numbers. ...
