To get exquisitely detailed imaging of the inside of the human body, today's medical practitioners turn to the MRI. To get to the roots of the MRI, researchers turn to I.I. Rabi and his ground-breaking exploration of Nuclear Magnetic Resonance in the 1940s. Rabi's work led to the 1944 Nobel Prize in Physics and supported not only the development of the MRI, but the atomic clock and the laser as well. To top off his legacy, Rabi was known for his love for and ability to teach younger generations of physicists. Find resources with additional information at the OSTI DOE R&D Accomplishments website. DOE R&D Accomplishments is a central forum for information about significant outcomes of past DOE R&D widely recognized as remarkable advancements in science.
