Reading sci-fi is a uniquely torturous experience for physicists. One eye on the narrative, the other eye scanning for violations of conservation of momentum.

The Martian was actually refreshing—only minor scientific liberties taken with that dust storm. Still spent three weeks calculating whether the potatoes would actually provide enough calories though.
