Don’t you just hate it when a multi-billionaire retiree says, “Even when my schedule is out of control, I carve out a lot of time for reading”? Anyway, Bill Gates has released his favorite books, and a couple caught my eye.

The Gene, by Siddhartha Mukherjee. Doctors are deemed a “triple threat” when they take care of patients, teach medical students, and conduct research. Mukherjee, who does all of these things at Columbia University, is a “quadruple threat,” because he’s also a Pulitzer Prize– winning author. In his latest book, Mukherjee guides us through the past, present, and future of genome science, with a special focus on huge ethical questions that the latest and greatest genome technologies provoke. Mukherjee wrote this book for a lay audience, because he knows that the new genome technologies are at the cusp of affecting us all in profound ways.

The Myth of the Strong Leader, by Archie Brown. This year’s fierce election battle prompted me to pick up this 2014 book, by an Oxford University scholar who has studied political leadership—good, bad, and ugly—for more than 50 years. Brown shows that the leaders who make the biggest contributions to history and humanity generally are not the ones we perceive to be “strong leaders.” Instead, they tend to be the ones who collaborate, delegate, and negotiate—and recognize that no one person can or should have all the answers. Brown could not have predicted how resonant his book would become in 2016.

Honorable mention: The Grid, by Gretchen Bakke. This book, about our aging electrical grid, fits in one of my favorite genres: “Books About Mundane Stuff That Are Actually Fascinating.” Part of the reason I find this topic fascinating is because my first job, in high school, was writing software for the entity that controls the power grid in the Northwest. But even if you have never given a moment’s thought to how electricity reaches your outlets, I think this book would convince you that the electrical grid is one of the greatest engineering wonders of the modern world. I think you would also come to see why modernizing the grid is so complex and so critical for building our clean-energy future.
