Startronics Library - Science 2 disk - release 1.0 July '91
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Welcome to EdLib's Science 2 collection. Due to the large amount of good
PD material on astronomy and related subjects, and the good response to
Science 1, we are presenting a second collection on astronomy.
The following are on this disk:
STARCHART: A very easy-to-use and fast night sky simulator that allows
fast and easy control over many aspects, including showing major
constellations, pre-setting star magnitude visibility, and much, much more.
We think this is one of the best programs around.
GRAVITY: Simulates the motion of astronomic objects.
GRAVSIM: A simulation of the effect of gravity on celestial objects, with
a very good interface which will allow animation of the results.
GRAVITY-WELL: A program that simulates motion in a Newtonian universe.
Has many features.
SCIENCE DEMOS drawer: The following programs are in BASIC. Not the most
ideal situation, but we hope someone will be inspired to rework them to
a better environment.
SIDEREAL: This is a tutorial program which introduces the user to the
relationships between Julian and calendar dates and solar and sidereal
times.
J2000: This is a utility program which converts stellar positions,
proper motion, parallax and radial velocity from the
standard epoch B1950 (FK4) to epoch J2000 (FK5). This method
is described on page X of the 1985 edition of the Astronomical Almanac.
GALILEAN: This is a tutorial program which determines the position of
the Galilean satellites relative to Jupiter. This program explains
how to construct position diagrams like those found in the Astronomical
Almanac and astronomy magazines.
