RadioActive welcomes University of Miami’s Dr. Ge-Chen Zha and freelance writer for NPR Aida Ramirez. A College of Engineering professor, Dr. Zha was awarded $100,000 grant from NASA’s prestigious Innovative Advanced Concepts program to create a supersonic, bi-directional flying wing (SBiDir-FW) that looks like something out of Star Wars. Dr. Zha’s fuel-efficient supersonic jet is capable of taking passengers to destinations in less time than current conventional aircraft. Aida Ramirez, a Miami native and UM Young alum, will be discussing "Who, Exactly, Is A Gringo?" – her article that was published by NPR, together with how the slang term has evolved overtime and who may classify as a gringo in the future.
