PCjs Machines

Here are several programs that simulate the orbits of celestial bodies
and small particles. Use them to simulate the orbit of a three-star
system, the orbit of a comet approaching the Earth, and the orbits of
the Earth, sun, and moon. PARTICLE SIMULATION also has programs that
simulate the movement of a particle inside an ellipse or an ellipsoid.
In addition, there's an explanation of the twin paradox of relativity:
why people should cease to age as they approached the speed of light.
Graphics are included in the explanation.

    PARTICLE SIMULATION has several programs that simulate the orbits of
celestial bodies and small particles. It can simulate the orbit of a
three-star system, the orbit of a comet approaching the earth, and the
orbits of the earth, sun, and moon. PARTICLE SIMULATION also has programs
that simulate the movement of a particle inside an ellipse or an ellipsoid,
the latter shown in three cross sections. Before each program begins, you
have the option of changing the parameters so you can see a different path
or outcome of the particle or celestial body. In addition, it has a program
that explains the "twin paradox" problem of relativity: why would people
cease to age as they approached the speed of light? The program has text
and graphics that explain this concept of the theory of relativity.

Usage: Particle Simulation

System Requirements: 128K memory, one floppy disk drive, and a CGA or EGA
color graphics card. Some programs require a 8087 math chip.

This is an update (as of Jan. 14, 1987) of 'Particle Simulation' disk X4321.
I re-organized it into a first part of two disk-series 'Math Software', of 
which the second is 'Differential Equations with parser'. Please ignore my 
previous versions of 'Particle Simulation' and 'Differential Equations' 
programs.

This disk is a Public Domain Software, and may freely copied and distributed
except for commercial purposes, although my second disk 'Differential Equations
with parser' is a shareware recommended for registration.
