Chemical Equilibrium

Gibbs Free Energy and Spontaneity

Introduction

In my previous couple of blog posts, I talked about a thermodynamic state function called enthalpy, and how it is used by scientists and engineers. This included covering a principle called Hess’s Law, which has led to the tabulation of enthalpy values for certain reactions under a set of standardized conditions, such that the idea could be generalized to make thermodynamic predictions about a huge variety of processes. Those posts laid the groundwork for the following topic.  (more…)

Admin Reflections (July 2018)

Since I started doing science blogging and skeptical outreach, I’ve noticed that my most popular posts usually involve topics that are considered controversial by the general public, even if they aren’t considered as controversial by actual experts: i.e. genetically engineered foods, anthropogenic climate change, the safety and efficacy of municipal water fluoridation, the importance of vaccines, and anti-science conspiracy speculationism.

The Streisand Threshold: Choosing one’s battles

There is a tremendous amount of pseudoscience and other misinformation that circulates-- seemingly unimpeded-- on the internet. Consequently, it can be a daunting task for those of us who fight against it to know which targets are an effective use of our time and effort. There are various considerations that might inform one’s decision about where (or toward whom) to direct one’s science advocacy or skeptical outreach: (more…)
