Braina (Brain Artificial) is a software tool that is designed to provide a natural language interfac (more)e for interacting with computers. It is a virtual assistant that is capable of performing a wide range of tasks and functions, including answering questions, performing web searches, and controlling other software programs. One of the key features of Braina is its ability to understand and process natural language commands and questions. This allows users to interact with their computer in a more intuitive and natural way, using the same types of language and communication that they use with other people. This can make it easier and more efficient for users to complete tasks and access information, as they do not need to learn specialized commands or interfaces. Braina also includes a range of features for assisting with tasks and functions, such as voice recognition, text-to-speech synthesis, and natural language processing. These features can help users to more effectively and accurately communicate with their computer, and they can make it easier for the computer to understand and respond to their requests. Overall, Braina is a powerful and flexible tool that is widely used by individuals and organizations as a virtual assistant and productivity tool. It is particularly useful for people who prefer to use natural language to interact with their computer, and it is often used in conjunction with other software programs and tools.

Dirac is a software program for performing quantum mechanical calculations in chemistry and physics. (more) It is used to study the properties of molecules, materials, and other systems at the atomic and subatomic level. Dirac is based on the Dirac equation, a fundamental equation of quantum mechanics that describes the behavior of particles, such as electrons and photons, in terms of wave functions. The software includes a range of features for performing quantum mechanical calculations, such as solving the Schrödinger equation, evaluating energy levels, and calculating wave functions and other quantities. Dirac is developed by a team at the University of Gothenburg in Sweden and is available for Windows, Linux, and Unix operating systems. It is widely used in research and industry to study the properties of chemical and physical systems. Operating system: Linux, FreeBSD, Microsoft Windows, macOS License: LGPL 2.1
