Maxim didn't look at his notes. He thought of the GDZ's explanation of Wien’s Displacement Law—the way the manual had simplified the relationship between color and heat. He raised his hand and explained it with such clarity that the classroom felt, for a moment, like the observation deck of a starship. The Legacy of the Book
