How are vectors used in real life? Vectors have many real-life applications, including situations involving force or velocity. For example, consider the forces acting on a boat crossing a river. The boat’s motor generates a force in one direction, and the current of the river generates a force in another direction. Both forces are vectors. […]

Why was Arctic sea ice so low in 2012?
Why was Arctic sea ice so low in 2012? It’s clear that Arctic sea ice is declining over time, although there are ups and downs each year. And scientists say the melt has been driven by both global warming and other pollutants that humans have put into the atmosphere. What was the sea ice minimum […]
