Science writer Eliza Strickland discovers that in the race to the bottom of the Mariana Trench the most important thing is what they leave behind.

Eliza Strickland is an editor for the magazine IEEE Spectrum, where she was assigned the daunting beat of covering technology across the Asian continent. On her third day on the job a tsunami flooded the Fukushima Daiichi nuclear power plant, causing the worst nuclear disaster since Chernobyl. She spent the next two years writing about the catastrophe, its human cost, and the future of energy. And this one time, in Seoul, she rode the world's fastest elevator.
