Mathematical Reason for Uncertainty in Quantum Mechanics

Today I'd like to give a fairly simple account of why Uncertainty Principles exist in quantum mechanics. I thought I already did this post, but I can't find it now. I often see in movies and sci-fi books (not to mention real-life discussions) a misunderstanding about what uncertainty means. Recall the classic form that says… Continue reading Mathematical Reason for Uncertainty in Quantum Mechanics

Statistical Oddities 5: Sequential Testing

Our next decision theory post is going to be on how to rephrase hypothesis testing in terms of Bayesian decision theory. We already saw in our last statistical oddities post that $latex {p}&fg=000000$-values can cause some problems if you are not careful. This oddity makes the situation even worse. We'll show that if you use… Continue reading Statistical Oddities 5: Sequential Testing
