Having studied theoretical physics, I would disagree with the statement that lectures are awesome. If anything, learning theoretical physics requires grappling with conceptually difficult material, where problem solving and debating the subject are essential. You can't learn it by passively memorizing information. It's conceptually simple, "orientation-like" material that can be learned fairly effectively with lectures.
