The Quantum Theory of Many Universes
Let’s begin with what many regard as the most extraordinary claim: the existence of parallel universes. The Everett interpretation of quantum mechanics, which I defend here, is not a speculative addition to physics—it is physics taken seriously. Quantum theory tells us that particles don’t have defi...

The Role of Scientific Explanation
A central claim of my philosophy is that knowledge is not a collection of observations but a network of explanations. Good explanations, I argue, are hard to vary while still accounting for what they explain. This criterion captures what makes scientific theories valuable: they don’t merely describe...
