Returning to grad school after a four-year hiatus, I find E&M as difficult as ever. In my days as an undergrad, E&M was my worst class despite my overall interest in the material. No other class caused so much gnashing of teeth! I know the problem is common. I find it easy to understand what the equations are telling me mathematically, but when it comes time to apply those equations to a practical physical problem, I do not know where to start. Why does there appear to be such a large discontinuity between E&M equations and physical problems? Can anyone suggest a better way of learning? Thanks!
