This underground soapstone mine looks unreal the moment you step inside, with massive green and blue walls opening into huge chambers that disappear into darkness in every direction. But the scale ...

Sometimes an offseason turns on the loud moments. Other times, it’s the smaller, procedural choices that quietly hint at a team’s priorities. Friday landed firmly in that second category for the New ...

The acid dissociation constant, K a, and its negative decadic log, pK a, are key life sciences parameters that describe molecular acidity. Specifically, these values indicate the protonation state of ...

One of the ways that per- and polyfluoroalkyl substances (PFAS) earn their “forever chemical” nickname and persist in the environment is their acidity. Many of these toxic chemicals are highly acidic, ...

For agencies like Summit Fire & EMS, the decision to send crews and equipment to a distant fire is a constant calculation of risk. "That's a daily decision, it's a moment-by-moment decision," ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Understanding the concept of pKa (the negative logarithm of the acid dissociation constant) is crucial for those who study chemistry, biochemistry, and other related fields. Knowing how to calculate ...

In the world of chemistry, equilibrium constants (Keq) and acid dissociation constants (pKa) play a vital role in understanding chemical reactions and their balance. The relationship between these two ...
