open source middleware system for volunteer and grid computing

free software planetarium

Celestia is a real-time 3D astronomy software program that was created in 2001 by Chris Laurel. The program allows users to virtually travel through the universe and explore celestial objects that have been catalogued. Celestia also doubles as a planetarium, but the user is not restricted to the Earth's surface, like in other planetarium software such as Stellarium. Celestia can display objects of various scales using OpenGL.

Folding@home (FAH or F@h) is a distributed computing project aimed to help scientists develop new therapeutics for a variety of diseases by the means of simulating protein dynamics. This includes the process of protein folding and the movements of proteins, and is reliant on simulations run on volunteers' personal computers. Folding@home is currently based at the University of Pennsylvania and led by Greg Bowman, a former student of Vijay Pande.

Bioconductor is a free, open source and open development software project for the analysis and comprehension of genomic data generated by wet lab experiments in molecular biology.

Prime95, also distributed as the command-line utility mprime for FreeBSD, Linux, and MacOS is a freeware application written by George Woltman. It is the official client of the Great Internet Mersenne Prime Search (GIMPS), a volunteer computing project dedicated to searching for Mersenne primes. It is also used in overclocking to test for system stability.

alt=LabPlot interface with column data and sparklines.|thumb|LabPlot can draw sparklines at top of the data columns to show a quick glance of the data before plotting them. LabPlot is a free and open-source, cross-platform computer program for interactive scientific plotting, curve fitting, nonlinear regression, data processing and data analysis. LabPlot is available, under the GPL-2.0-or-later license, for Windows, macOS, Linux, FreeBSD and Haiku operating systems.

MAXQDA is a computer-assisted qualitative data analysis (CAQDAS) application used for qualitative and mixed methods research. Developed and distributed by VERBI Software in Berlin, Germany, it runs on Windows and macOS and supports projects containing textual materials, PDFs, images, audio and video (including transcripts), and structured survey data.

ChemDraw™ is a molecule editor and communication suite, for the management, reporting, and presentation of chemistry research and discoveries.

open-source astronomy visualisation program

KAlgebra is a mathematical graph calculator included in the KDE education package. While it is based on the MathML content markup language, knowledge of MathML is not required for use. The calculator includes numerical, logical, symbolic, and analytical functions, and can plot the results onto a 2D or 3D graph. KAlgebra is free and open source software, licensed under the GPL-2.0-or-later license.

XEphem is a Motif based ephemeris and planetarium program for Unix-like operating systems developed by Elwood C. Downey.
