Confessions of a moderate Bayesian part 3 Read part 1: How to Get Started with Bayesian Statistics Read part 2: Frequentist Probability vs Bayesian Probability Bayesian statistics by and for non-statisticians https://www.cafepress.com/physicsforums.13280237 Background One of the things that I like about Bayesian statistics is that it rather closely matches the way that I think about…

Exploring Frequentist Probability vs Bayesian Probability

December 3, 2020/38 Comments/in Mathematics Articles/by Dale

Confessions of a moderate Bayesian, part 2 Read Part 1: Confessions of a moderate Bayesian, part 1 Bayesian statistics by and for non-statisticians https://www.cafepress.com/physicsforums.13280237 Background One of the continuous and occasionally contentious debates surrounding Bayesian statistics is the interpretation of probability. For anyone familiar with my posts on this forum, I am not generally a…

How to Get Started with Bayesian Statistics

November 28, 2020/13 Comments/in Mathematics Articles/by Dale

Confessions of a moderate Bayesian, part 1 Bayesian statistics by and for non-statisticians https://www.cafepress.com/physicsforums.13265286 Background I am a statistics enthusiast, although I am not a statistician. My training is in biomedical engineering, and I have been heavily involved in the research and development of novel medical imaging technologies for the bulk of my career. Due…

PF’s policy on Lorentz Ether Theory and Block Universe

September 22, 2015/81 Comments/in Physics FAQs/by Dale

What is the PF’s policy on Lorentz Ether Theory and Block Universe? Debates about the superiority or “truth” of modern Lorentz Ether Theory (LET) and the Block Universe (BU) concept are outside the scope of PF because: There is little or no debate among professional physicists about these issues (as opposed to e.g. interpretations of…

Understanding the General Relativity View of Gravity on Earth

July 20, 2015/102 Comments/in Physics Articles/by Dale

Often students have difficulty reconciling the General Relativity (GR) view of gravity versus their own experience with gravity on the surface of Earth. This article covers some of the basic concepts and explains how they work with “every day” gravity. Non-inertial Frames and Fictitious Forces Physics is traditionally taught using inertial frames, however, there is…

A Definition and Controversy of Energy

May 27, 2015/44 Comments/in Physics Articles/by Dale

[CONTENT] What is energy? Energy is a fundamental concept that refers to the capacity of a system to do work. It is a scalar quantity, meaning it has magnitude but no specific direction. Energy is a crucial concept in understanding the behavior of the physical world, and it comes in various forms, each with its…
