Dresden Files Physics: Part 2

Here is another exploration of the science behind Jim Butcher's popular Dresden Files books. Harry Dresden has a magical shield bracelet, which obeys several concepts of physics rather well. Caution, tiny spoilers ahead. At first, Harry's bracelet enables him to block incoming kinetic energy only, which causes him some problems when exposed to heat. He later expands it to also block heat energy, light and sound as well. The fact that each type of energy needs to be addressed separately, combined with the fact that powering the improved bracelet takes more of an effort from Harry, demonstrates the idea of conservation of energy and shows the level of thought Butcher puts into the magic in his books.
