GraphCalc is a software program that is used for graphing and analyzing mathematical functions. It i (more)s a multi-functional calculator that allows users to input and graph a wide range of functions, including polynomial, rational, exponential, and logarithmic functions. It also provides tools for performing statistical analysis and other mathematical operations. GraphCalc is designed for use by students, educators, and researchers who need to visualize and analyze mathematical functions. It is a useful tool for exploring and understanding the properties of different functions, and it can be used for tasks such as finding the roots of equations, determining the intersection points of graphs, and calculating the area under a curve. GraphCalc is available for Windows and macOS operating systems, and it is often used in conjunction with other math and science software programs. It is a powerful and flexible tool that is suitable for a wide range of applications in the fields of mathematics, science, and engineering.

Einstein@Home is a distributed computing project that uses idle computer time to search for gravitat (more)ional waves and other phenomena in data collected by the Laser Interferometer Gravitational-Wave Observatory (LIGO). It is a volunteer computing project that relies on the contributions of individuals around the world who donate their idle computer time to help analyze the data. Einstein@Home is named after Albert Einstein, whose theory of general relativity predicted the existence of gravitational waves. These waves are thought to be ripples in the fabric of space-time that are created by the acceleration of massive objects, such as black holes and neutron stars. The detection of gravitational waves is a major milestone in the field of physics, as it provides a new way to study the universe and test the predictions of Einstein's theory. Einstein@Home is managed by a team of scientists and researchers from institutions around the world, and it is supported by a number of organizations, including the University of Wisconsin-Milwaukee and the Max Planck Institute for Gravitational Physics. The project is open to anyone who is interested in contributing their idle computer time to the search for gravitational waves. Operating system: Cross-platform License: GPL-2.0-or-later

RasMol is a computer program that is used to visualize and manipulate molecular structures. It is a  (more)widely used tool in the field of chemistry, and it is particularly useful for studying the structure and properties of proteins and other biological molecules. RasMol allows users to view and analyze the three-dimensional structure of molecules, and it provides a number of features that make it easy to manipulate and analyze the data. Users can rotate and zoom in on molecules, change the display style, and apply various coloring schemes to highlight specific features of the molecule. They can also use RasMol to measure distances, angles, and other structural properties of the molecule. RasMol is available as a free, open-source program, and it is widely used in academia, research, and industry. It is compatible with a number of operating systems, including Windows, macOS, and Linux. Operating system: Unix, Windows License: GPL
