QUOTE : weirdly, thought of a problem put forth by his high school physics teacher: How can you make a marble bed as soft as a Simmons mattress? The answer: Dig out a depression in that marble the exact size and shape of a human body. Then when you lie in that depression, the pressure will be evenly distributed and it would feel incredibly soft. He closed his eyes and imagined that the warmth of his body was melting the iron ore beneath him and forming that kind of depression.… Gradually, this calmed him.
