Two-channel multi-tone audio frequency sinusoidal & noise signal generator is intended for adjusting and measuring parameters of audio equipment. Independent channels frequency and amplitude controls. A step of frequency setting is 0.00001 %; level - 0.001 dB; phase - 0.001 degree. The minimum coefficient of nonlinear and intermodulation distortion, precision, stability and range of frequency are limited only to quality of the used sound card.

Zoom and spin your way around the globe while viewing earthquakes in 3D. Adjust and customize the display to see earthquakes in a variety of different ways. Filter earthquakes by size and time - then select from many options that include quake indicators and map references. Earthquakes are shown in near real-time using the latest data from the USGS via the internet.

Earth Explorer integrates high resolution satellite imagery and political boundaries, coastlines, rivers, 267 countries and regions, 40000+ ranked cities, 15000+ islands and 1700+ noteworthy historical earthquakes since 1980 into a fantastic 3D earth globe. You can specify what kinds of map layers to be shown, rotate the globe, click right mouse button and pull/push to zoom in/out the current view, measure distance between any two points, etc.

Gravit is a gravity simulator which runs under Linux, Windows and Mac OS X. It's released under the GNU General Public License which makes it free. It uses Newtonian physics using the Barnes-Hut N-body algorithm. Although the main goal of Gravit is to be as accurate as possible, it also creates beautiful looking gravity patterns.

See 2500 stars, all 88 constellations, planets and the moonphase from 1600 AD to 9999 AD from any location on earth. Click star on screen for detailed information. Geocentric and heliocentric views also available. Define your own five locations for quick switch. Print todays night sky ! Tiny program, but great planetarium, especially for teachers and students. Nice visuals, smooth animation, simple controls, good planet data too.

Model ChemLab is a unique product incorporating both an interactive simulation and a lab notebook workspace with separate areas for theory, procedures and student observations. Commonly used lab equipment and procedures are used to simulate the steps involved in performing an experiment. Users step-through the actual lab procedure while interacting with animated equipment in a way that is similar to the real lab experience.
