The Tulsa Race Riot of 1921 was the worst civil disturbance since the Civil War. On May 21, 1921, a group of white Oklahomans attacked the prosperous African American community, called the Greenwood District or "the Black Wall Street" in Tulsa, OK over the alleged assault of a white woman by a black man. 24 hours later more than 800 people were admitted to local hospitals, 10,000 residents were homeless, and 35 city blocks were reduced to rubble. The monetary cost of the riot was later estimated to be 26 million dollars. This report examines the events leading up to the riot, the riot itself, and the consideration of reparations for the victims.

M. C. Roco and W.S. Bainbridge In the early decades of the 21st century, concentrated efforts can unify science based on the unity of nature, thereby advancing the combination of nanotechnology, biotechnology, information technology, and new technologies based in cognitive science. With proper attention to ethical issues and societal needs, converging in human abilities, societal technologies could achieve a tremendous improvement outcomes, the nation's productivity, and the quality of life. This is a broad, cross cutting, emerging and timely opportunity of interest to individuals, society and humanity in the long term. The phrase "convergent technologies" refers to the synergistic combination of four major "NBIC" (nano-bio-info-cogno) provinces of science and technology, each of which is currently progressing at a rapid rate: (a) nanoscience and nanotechnology; (b) biotechnology and biomedicine, including genetic engineering; (c) information technology, including advanced computing and communications; (d) cognitive science, including cognitive neuroscience. Timely and Broad Opportunity. Convergence of diverse technologies is based on material unity at the nanoscale and on technology integration from that scale.
