The rate of feeding one reactant in the system and the rate of removing another reactant from the system determine configurations of concentration profiles: stripes, spots, waves. In the early s, Walker's discovery of fossil nuclear particle tracks in minerals was instrumental to new developments in geo-chronology and cosmic ray physics.
Walker worked on the frontiers of space research for more than four decades.
Robert Walker was born in Philadelphia on 6 February His mother was Dorothy Potter and he considered Roger Potter his father though he was not his biological father. He subsequently joined the General Electric Laboratory in Schenectady, New York where he studied the radiation effects in solids. His work on defects in irradiated copper is still regarded as the definitive work on the topic.
In the early s, Walker's discovery of fossil nuclear particle tracks in minerals was instrumental to new developments in geo-chronology and cosmic ray physics. In particular, his discovery of tracks from nuclei heavier than iron opened a new frontier of cosmic ray physics.
The interview addresses many different questions including why Altman became a pilot, the events that led to his interest, his career path through the Navy, and then finally, his selection by NASA as an astronaut.
Other interesting information discussed in this one-on-one interview was his work on the movie set of "Top Gun," the highlights of his Navy career, and possible shorter time frame turnarounds for missions.
He answers questions about his inspiration to become an astronaut, his career path, training for the mission, and his role in the mission's activities. He gives details on the mission's goals, which include the transfer of supplies from the Discovery Orbiter to the International Space Station ISS and the change-over of the Expedition 2 and Expedition 3 crews the resident crews of ISS.
Horowitz discusses the importance of the ISS in the future of human spaceflight. STS is scheduled for liftoff on Feb. Kelly is seen.
The interview addresses many different questions including why Kelly became an astronaut, the events that led to his interest, any role models that he had, and his inspiration.
