What Will Earth Look Like When These 6 Tipping Points Hit?
A “tipping point” is when a system, with just a small amount of additional energy, is pushed from one stable state to another suddenly and dramatically. This can be a chair falling backwards. Or it can be a major earth system collapsing....

Difference between acids and bases. And why supervillains love them.
What is the difference between acids and bases? This is a commonly asked question in both chemistry and biology classes. In this video, we will go through the definition of acid and base, and why they are so important to us, and, uh,...
