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. Vanish Fat Burner Arvustused 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. He subsequently pioneered the use of plastics to detect and count such nuclei in cosmic ray balloon flights.

Beginning inwhen he moved to Washington University and became the first McDonnell Professor of Physics, his research interests turned more toward space physics. He was the inaugural director of the McDonnell Center, which was established in by a gift from aerospace pioneer James S. Walker was a member of the NASA committee that allocated samples of the first returned lunar materials, and his laboratory led the way in deciphering their record of lunar, solar system and galactic evolution.

Together with Ghislaine Crozaz and other colleagues, Walker made path breaking laboratory studies of the first moon rocks revealing the history of solar radiation and Index Scriptorium Estoniae TLÜ Kultuuriteaduste ja kunstide doktorikooli kutsel Tallinnas viibinud sotsioloogi, Leedsi ülikooli emeriitprofessori Zygmunt Baumani ja TLÜ juhtivteadur Rein Raua vahel Kirjanike Liidu saalis toimunud avalikust vestlusest.
