I’ve been tremendously lucky to have the opportunity to work with BBC Earth and Pomona Pictures over the past few months, creating a series of animated videos to explain ideas in physics, astronomy, and even a little philosophy. Here they are:Read more "Science videos!"
The Sapir-Whorf hypothesis states that language affects thought — how we speak influences how we think. Or, at least, that’s one form of the hypothesis, the weak form. The strong form of Sapir-Whorf says that language determines thought, that how we speak forms a hard boundary on how and what we think. The weak form of Sapir-Whorf says that we drive an ATV across the terrain of thought; language can smooth the path in some areas and create rocks and roadblocks in others, but it doesn’t fundamentally limit where we can go. The strong form, in contrast, says we drive a steam train of thought, and language lays down the rails. There’s an intricate maze of forks and switchbacks spanning the continent, but at the end of the day we can only go where the rails will take us — we can’t lay down new track, no matter how we might try…Read more "Weak Forms and Strong Forms"
Here’s a question I’ve gotten several times since starting this blog a few days ago (and several dozen times over the last few years):
“Scientists make a lot of noise about being ‘objective’ and using data to determine the truth, but at the end of the day, science has an untested — and untestable — core belief: that we can learn the nature of reality by actively studying the physical world. So doesn’t this mean that science is a form of faith, no different from any other system of belief?”
Short answer: yes to the first part, no to the second part.
Long answer…Read more "How Do We Know That Science Works?"
