The Rational Optimist: How Prosperity Evolves

Life is getting better—and at an accelerating rate. Food availability, income, and life span are up; disease, child mortality, and violence are down — all across the globe. Though the world is far from perfect, necessities and luxuries alike are getting cheaper; population growth is slowing; Africa is following Asia out of poverty; the Internet, the mobile phone, and container shipping are enriching people’s lives as never before. The pessimists who dominate public discourse insist that we will soon reach a turning point and things will start to get worse. But they have been saying this for two hundred years.

Yet Matt Ridley does more than describe how things are getting better. He explains why. Prosperity comes from everybody working for everybody else. The habit of exchange and specialization—which started more than 100,000 years ago—has created a collective brain that sets human living standards on a rising trend. The mutual dependence, trust, and sharing that result are causes for hope, not despair.

This bold book covers the entire sweep of human history, from the Stone Age to the Internet, from the stagnation of the Ming empire to the invention of the steam engine, from the population explosion to the likely consequences of climate change. It ends with a confident assertion that thanks to the ceaseless capacity of the human race for innovative change, and despite inevitable disasters along the way, the twenty-first century will see both human prosperity and natural biodiversity enhanced. Acute, refreshing, and revelatory, The Rational Optimist will change your way of thinking about the world for the better.

A Course in Machine Learning

Machine learning is the study of algorithms that learn from data and experience. It is applied in a vast variety of application areas, from medicine to advertising, from military to pedestrian. Any area in which you need to make sense of data is a potential consumer of machine learning.

CIML is a set of introductory materials that covers most major aspects of modern machine learning (supervised learning, unsupervised learning, large margin methods, probabilistic modeling, learning theory, etc.). It's focus is on broad applications with a rigorous backbone. A subset can be used for an undergraduate course; a graduate course could probably cover the entire material and then some.

The Secrets of D.B. Cooper, Part One - Notorious Flight 305

Would you jump into a mountain forest for $1,052,000? In the dark? In the rain? In November?

In 1971, one man did. Unfortunately, the cash was stolen and the aircraft was hijacked Boeing 727 with fighter jets and FBI agents in a helicopter following it.

Was he an experienced skydiver or an ordinary criminal attempting an extraordinary theft? Did he survive and escape, or perish in a forest in Washington State? Decades later, no one knows for sure.

The Secrets of D.B. Cooper, Part Three - Criminal Profile

For whatever reason, hundreds of people are convinced they know who D.B. Cooper was—or themselves admitted to being the most recognized hijacker in the world. Maybe it’s the extraordinary circumstantial evidence. Maybe it’s the desperate need for an answer. Maybe it’s a secret wish to make a difference in the world. But sometimes, no matter how hard we wish, no matter how hard we believe, we just can’t make something true. Today, the FBI has DNA from Cooper’s J.C. Penney clip-on tie that he left on the jet and partial fingerprints from the cocktail glasses he drank from while in flight. They can now quickly confirm or eliminate suspects.

Mental Models I Find Repeatedly Useful

A mental model is just a concept you can use to help try to explain things (e.g. Hanlon’s Razor?—?“never attribute to malice that which is adequately explained by carelessness.”). There are tens of thousands of mental models, and every discipline has their own set that you can learn through coursework, mentorship, or first-hand experience.

There is a much smaller set of concepts, however, that come up repeatedly in day-to-day decision making, problem solving, and truth seeking. As Munger says, “80 or 90 important models will carry about 90% of the freight in making you a worldly?wise person.”
