Please answer the following question: Information: - A physicist is a scientist who has specialized knowledge in the field of physics, the exploration of the interactions of matter and energy across the physical universe. - General Atomics is a defense contractor headquartered in San Diego, California, specializing in nuclear physics. General Atomics' research into nuclear fission and nuclear fusion has also had bearing on related technologies, allowing the company to expand into other fields of research and manufacturing. General Atomics develops systems ranging from the nuclear fuel cycle to remotely operated surveillance aircraft, airborne sensors, advanced electric, electronic, wireless, and laser technologies. - The American Physical Society (APS) is the world's second largest organization of physicists. The Society publishes more than a dozen scientific journals, including the prestigious "Physical Review" and "Physical Review Letters", and organizes more than twenty science meetings each year. APS is a member society of the American Institute of Physics. - Charles F. Kennel ( born 1939 ) is an American scientist and member of the United States National Academy of Sciences born in Cambridge , Massachusetts . Kennel received a bachelor 's degree in astronomy from Harvard College and a doctorate in astrophysical sciences from Princeton University . In 1997 he received the James Clerk Maxwell Prize in Plasma Physics . In 2009 , he was advertised by NASA Watch as a potential pick by Barack Obama as the next NASA Administrator . - The James Clerk Maxwell Prize in Plasma Physics is an annual American Physical Society (APS) award that is given in recognition of outstanding contributions to the field of the Plasma Physics. It was established in 1975 by Maxwell Technologies, Inc, in honor of the Scottish physicist James Clerk Maxwell. It is currently sponsored by General Atomics. The prize includes a $10,000 USD monetary award and recognition at the annual American Physical Society Division of Plasma Physics conference. - The National Aeronautics and Space Administration (NASA ) is an independent agency of the executive branch of the United States federal government responsible for the civilian space program as well as aeronautics and aerospace research. - Aerospace is the human effort in science, engineering and business to fly in the atmosphere of Earth (aeronautics) and surrounding space (astronautics). Aerospace organisations research, design, manufacture, operate, or maintain aircraft and/or spacecraft. Aerospace activity is very diverse, with a multitude of commercial, industrial and military applications. - Aeronautics (from the ancient Greek words "r", which means "air", and "nautik" which means "navigation", i.e. "navigation into the air") is the science or art involved with the study, design, and manufacturing of air flight capable machines, and the techniques of operating aircraft and rockets within the atmosphere. The British Royal Aeronautical Society identifies the aspects of "aeronautical Art, Science and Engineering" and "the profession of Aeronautics (which expression includes Astronautics)."
