High-quality beams could be among the first practical applications of the booming field of topological physics.
In this oral history video, Dick Karp, founding director of the Simons Institute for the Theory of Computing, discusses some of the key developments in theoretical computer science during his long and distinguished career. He stepped down as director at the end of 2017.
Topological effects might be hiding inside perfectly ordinary materials, waiting to reveal bizarre new particles or bolster quantum computing.
Africa and Asia are absorbing more refugees than the European Union. Misleading reports about the magnitude of flows into Europe and the U.S. are creating unjustified fears about refugees, thereby undermining efforts to manage the massive humanitarian problems.
