Thank you for viewing this video on Sky Scholar! This channel is dedicated to new ideas about the nature of the sun, the stars, thermodynamics, and the microwave background. We will discuss all things astronomy, physics, chemistry, and imaging related! We hope that the combination of facts and special effects will aid in learning even the toughest concepts in astronomy. If you enjoyed this video, please subscribe. Sky Scholar will be releasing at least one video per week to make sure you don’t run out of content!
Pierre-Marie Robitaille, Ph.D., is a professor of radiology at The Ohio State University. He also holds an appointment in the Chemical Physics Program. In 1998, he led the design and assembly of the world’s first Ultra High Field MRI System. This brought on the need to question fundamental aspects of thermal physics, including ideas related to Kirchhoff’s Law of thermal emission, and more. These presentations are not endorsed by The Ohio State University.
