Wilmington, North Carolina once had a thriving Black middle class and an elected interracial government. In 1898 white supremacists used violence to overthrow that government, kill Black residents and drive many others from the city.

The Open Dynamics Engine (ODE) is a physics engine written in C/C++. Its two main components are a rigid body dynamics simulation engine and a collision detection engine.[3] It is free software licensed both under the BSD license and the LGPL.
ODE was started in 2001 and has been used in many applications and games, such as Assetto Corsa, BloodRayne 2, Call of Juarez, S.T.A.L.K.E.R., Titan Quest, World of Goo, X-Moto, Mad Tracks and OpenSimulator.
The Open Dynamics Engine is used for simulating the dynamic interactions between bodies in space. It is not tied to any particular graphics package although it includes a basic one called drawstuff.[4] It supports several geometries: box, sphere, capsule (cylinder capped with hemispheres), triangle mesh, cylinder and heightmap.
Higher level environments that allow non-programmers access to ODE include Player Project, Webots, Opensimulator, anyKode Marilou and CoppeliaSim.
ODE is a popular choice for robotics simulation applications, with scenarios such as mobile robot locomotion[5][6] and simple grasping. ODE has some drawbacks in this field, for example the method of approximating friction and poor support for joint-damping.[7]

Webots is a free and open-source 3D robot simulator used in industry, education and research. The Webots project started in 1996, initially developed by Dr. Olivier Michel at the Swiss Federal Institute of Technology (EPFL) in Lausanne, Switzerland and then from 1998 by Cyberbotics Ltd. as a proprietary licensed software. Since December 2018, it is released under the free and open-source Apache 2 license. Webots includes a large collection of freely modifiable models of robots, sensors, actuators and objects. In addition, it is also possible to build new models from scratch or import them from 3D CAD software. When designing a robot model, the user specifies both the graphical and the physical properties of the objects. The graphical properties include the shape, dimensions, position and orientation, colors, and texture of the object. The physical properties include the mass, friction factor, as well as the spring and damping constants. Simple fluid dynamics is present in the software. Webots uses a fork of the ODE (Open Dynamics Engine) for detecting of collisions and simulating rigid body dynamics. The ODE library allows one to accurately simulate physical properties of objects such as velocity, inertia and friction. Webots includes a set of sensors and actuators frequently used in robotic experiments, e.g. lidars, radars, proximity sensors, light sensors, touch sensors, GPS, accelerometers, cameras, emitters and receivers, servo motors (rotational & linear), position and force sensor, LEDs, grippers, gyros, compass, IMU, etc. The robot controller programs can be written outside of Webots in C, C++, Python, ROS, Java and MATLAB using a simple API. Webots offers the possibility to take screenshots and record simulations. Webots worlds are stored in cross-platform *.wbt files whose format is based on the VRML language. One can also import and export Webots worlds and objects in the VRML format. Users can interact with a running simulation by moving robots and other objects with the mouse. Webots can also stream a simulation on web browsers using WebGL.
anyKode Marilou is a modeling and simulation environment for mobile robots, humanoids, articulated arms and parallel robots operating in real-world conditions that respect the laws of physics. This robotics suite is used in research centers and industry for various projects like humanoid architectures, wheeled and multi legged vehicles, and multi-robot systems (Multi-agents). It also has a real-time engine that uses the ODE (Open Dynamics Engine) for collisions detecting and dynamics management. Various 'real world' variables like forces, torques, masses, damping, friction and others can be adjusted directly to the objects surfaces.

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.
