How To Clear Icy Roads, With Science
Icy roads are a huge hazard, and typical methods of de-icing them can be pretty toxic to wildlife. Which is why researchers have been so fixated on finding better alternatives, from brine to pig pee.

Water Potential
Paul Andersen explains how populations experience exponential. He begins by address the major players; N (population size) and r (growth rate). He models population growth in rabbits through four generations. He then shows you how to use...

Ionic Bonding
In this video Paul Andersen explains how ionic solids form when cations and anions are attracted. When atoms lose or gain electrons they form ions. The strength of the attraction between ions is based on the amount of charge and the...
