Thoughts on AI, technology, health, and life.
Quantum computing exploits two phenomena with no classical analog — superposition and entanglement — to perform certain calculations exponentially faster than any classical computer. The mathematics requires only linear algebra over the complex numbers, but the physical interpretation is deeply …
Read more →The transformer architecture, introduced in the landmark 2017 paper Attention Is All You Need, fundamentally changed how we process sequences. Unlike recurrent networks that process tokens one at a time, transformers process entire sequences in parallel using a mechanism called …
Read more →Quantum Electrodynamics (QED) is the quantum field theory that describes how light and matter interact. It is the most precisely tested theory in all of science — its predictions match experiment to better than one part in a trillion. Understanding …
Read more →If you enjoy wine — a good Burgundy, a crisp Chablis, or anything else — do not expect health benefits. That belief isn't supported by science. Where the Idea Came From The health-benefits hypothesis has a long history, but it …
Read more →String theory is one of the most ambitious — and most controversial — projects in the history of physics. Its central claim is deceptively simple: the fundamental constituents of nature are not point-like particles but tiny one-dimensional objects called strings. …
Read more →Good health does not require a complicated protocol. The fundamentals are unglamorous, well-established, and -- this is the tricky part -- actually have to be done consistently. Sleep First If you only optimize one thing, make it sleep. The evidence …
Read more →Artificial intelligence is moving fast. Every month brings new capabilities that would have seemed like science fiction a decade ago. With that speed comes an urgent question: how do we make sure these systems are actually good for people? What …
Read more →Large language models (LLMs) like GPT-4 and Claude have become household names, but the mechanics behind them remain mysterious to most people. This post gives you an honest, accessible picture of what is actually going on. It All Starts with …
