In the words of a Harvard researcher:
I’m a brain-computer interfaces researcher now, but when I was in high school and doing research in MRI, and I was looking everywhere for material on the physics of MRI.
I watched every course I could find but they were targeted towards medical students, so they would only tell you how MRI works at a very high level. Years later, when I got to Harvard, I took this class that finally told me how MRIs work, and there were these incredible lecture notes available! But the notes were not public; the knowledge was only accessible in this class.
I would have done anything to have had these notes available in high school.
