Colleges, businesses, and bureaucracies have long operated on an "old power" model — rigid hierarchies that rule from the top down. But Henry Timms says that paradigm is going extinct. In his book, "New Power: How Power Works in Our Hyperconnected World — and How to Make It Work for You," Timms argues there's another force emerging. It's transparent, collaborative — and it's going to embolden all of us to change the world from the bottom up.

As a college student, Zachary Wood ignited a national debate when he invited controversial speakers — anti-feminists, climate-change deniers, and self-proclaimed racists — to lecture on campus. Critics accused him of promoting dangerous ideas. But in his new memoir, "Uncensored," Wood argues that we can develop empathy and understanding by engaging with opposing viewpoints.
