Orbit Xplorer 2.2
Great for `lab exercises` in gravitational physics or for verifying numerical answers to textbook problems. Includes 30 introductory to advanced premade simulations with activities page in html-format. Simulations include elliptical satellite orbits, Kepler`s laws, double star, geocentric and heliocentric world view, Lagrange points, gravity assist, Hohmann orbit, extrasolar planet, inner solar system. Uses actual pictures of planets.
Plot orbits in a plane or in 3D. View time, distances, speeds, accelerations, energies and acceleration vectors as they change. Adjust the simulation speed to fit your computer. Zoom and change parameters during the simulation. Run up to four simultaneous simulations.
Tutorial and context-sensitive help included.
A program to search for eclipses (lunar, solar, total, annular and umbral), to calculate the phase of the Moon at any given date and time and to convert between dates in the Gregorian and Julian calendars and dates in four lunar calendars.
Astronomy software to simulate how astronomical objects move and interact under the force of gravity. It features superb interactive 3D graphics which allow you to move around within a many-body astronomical system, while watching how it evolves.
Scientific Calculator Precision 72 for scientists, engineers, teachers, and students. Calculates mathematical formulas of any length and complexity.
The AstroViewer planetarium software displays an interactive sky map for any time and any location on Earth. A print function and a 3D solar system map are available as well.
This software gives you vast information about all the elements of the modern Periodic Table. Name, atomic number, atomic weight,boiling and melting points of each element and much more. Molecular weight calculator, Periodic Table wallpaper included.
