This week I finished: The Power of Habit: Why We Do What We Do in Life and Business, by Charles Duhigg: Approaching a quarter-million burpees without missing a day in over a decade, among other habits, I always enjoy reading about habits. This book is engaging. Duhigg tells stories, presents science, and builds engagement over the course of the book well. I still haven’t found someone who treats how not[…] Keep reading →

Several bestselling authors on the environment suggest that people solve problems, so more people solve more problems. They conclude that we should keep growing the population. A century and a half ago people believed “rain follows the plow.” They created what looked like science proving that settlers moving west across North America creating farms would cause rain to fall more. To me, “more people solve more problems” looks like a[…] Keep reading →

People who fly think most people fly, but it’s more like a few percent. A small fraction of people fly, let alone across oceans or multiple times per year. If you fly, it’s probably your action that hurts people most through its environmental impact, but you probably rationalize and justify it. Unlike many other polluting activities, most of the money you spend on flying goes to polluting, displacing people and[…] Keep reading →

When I started graduate school in physics at the University of Pennsylvania, one of the faculty members in the department confused the students. He didn’t confuse us with complex science. He was a world leader in his subject, but the subject was tennis—the physics of tennis. I studied there in 1993-94. When the professor, Howard Brody, died, the New York Times published his obituary, Howard Brody, an Expert in the[…] Keep reading →

Everyone talks about our ancestors like they struggled for food. Many people believe we store fat well because our ancestors didn’t know when they’d next eat. Maybe they look at surviving hunting and gathering cultures and see less food than in their local supermarket. Look at nature, though. Animals and plants aren’t starving all the time. On the contrary, places that aren’t frozen, desert, or that we’ve paved over abound[…] Keep reading →

Environmentalists talk about the possibility of a future collapse. They talk about the harm happening far away. I don’t want to take away from those problems and risks, but they are missing what’s happening here and now with all of us. We can’t look our children in the eye and tell them they’ll live in a safer, healthier, more secure world. Since we can’t, we tell them what we do[…] Keep reading →

Since I’ve learned to love fresh vegetables and fruit, I’ve come to learn the restaurants hate them. Caterers do too. An ex-girlfriend once commented that she couldn’t go to restaurants with me because I complained too much that they covered everything in salt, sugar, and fat (more on that complaint below). I attended an event today that was catered. Everything was vegan, which a lot of people interpret to mean[…] Keep reading →
