Moments that changed communities, movements, institutions and the nation.
In August 1908, a white mob attacked Springfield, Illinois’s Black community, destroying homes and businesses and lynching two Black men. National outrage over the violence helped spur the movement that created the NAACP the following year.

This is a list of quantum software, including software development kits, programming languages, instruction set architectures, intermediate representations, simulators, and cloud platforms used in quantum computing. Quantum software is used to design quantum algorithms, create and manipulate quantum circuits, compile programs for quantum processors, simulate quantum systems on classical computers, and run experiments on cloud-accessible quantum hardware.
Quantum chemistry computer programs are used in computational chemistry to implement the methods of quantum chemistry. Most include the Hartree–Fock (HF) and some post-Hartree–Fock methods. They may also include density functional theory (DFT), molecular mechanics or semi-empirical quantum chemistry methods. The programs include both open source and commercial software. Most of them are large, often containing several separate programs, and have been developed over many years.
This is a list of notable computer programs that are used to model nanostructures at the levels of classical mechanics and quantum mechanics. Furiousatoms - a powerful software for molecular modelling and visualization Aionics.io - a powerful platform for nanoscale modelling Ascalaph Designer Atomistix ToolKit and Virtual NanoLab CoNTub CP2K CST Studio Suite Deneb – graphical user interface (GUI) for SIESTA, VASP, QE, etc., DFT calculation packages Enalos Cloud Platform – a cloud platform containing tools for the digital construction of energy minimized nanotubes and ellipsoidal nanoparticles and the calculation of their atomistic descriptors. Exabyte.io - a cloud-native integrated platform for nanoscale modeling, supporting simulations at multiple scales, including Density Functional Theory and Molecular Dynamics JCMsuite – a finite element analysis software for simulating optical properties of nanostructures LAMMPS – Open source molecular dynamics code MAPS - Graphical user interface to build complex systems (nanostructures, polymers, surfaces...), set up and analyze ab-initio (Quantum Espresso, VASP, Abinit, NWChem...) or classical (LAMMPS, Towhee) simulations Nanoengineer-1 – developed by company Nanorex, but the website doesn't work, may be unavailable nanoHUB allows simulating geometry, electronic properties and electrical transport phenomena in various nanostructures Nanotube Modeler NEMO 3-D – enables multi-million atom electronic structure simulations in empirical tight binding; open source; an educational version is on nanoHUB and Quantum Dot Lab nextnano allows simulating geometry, electronic properties and electrical transport phenomena in various nanostructures using continuum models (commercial software) Ninithi – carbon nanotube, graphene, and Fullerene modelling software Materials Design MedeA Materials Studio Materials Square - a cloud-based materials simulation web platform, provides GUI for Quantum Espresso, LAMMPS, and Open Calphad MBN Explorer and MBN Studio MD-kMC PARCAS – Open source molecular dynamics code SAMSON: interactive carbon nanotube modeling and simulation Scigress TubeASP Tubegen Wrapping
This is a list of free and open-source software (FOSS) packages, computer software licensed under free software licenses and open-source licenses. Software that fits the Free Software Definition may be more appropriately called free software; the GNU project in particular objects to their works being referred to as open-source. For more information about the philosophical background for open-source software, see free software movement and Open Source Initiative. However, nearly all software meeting the Free Software Definition also meets the Open Source Definition and vice versa. A small fraction of the software that meets either definition is listed here. Some of the open-source applications are also the basis of commercial products, shown in the List of commercial open-source applications and services.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
