There are some incredibly complex aerodynamic principles going on here. For example, why are there ripples? At what distance does the wiper no longer have an affect on the water? | Smarter Every Day

Amazing bird's formation;are often the results of aerodynamic principles that help birds conserve energy during flight,most famously the V- formation,which allows them to take advantage of updrafts created by the bird infront. #birdphotography #naturelovers #highlighteveryone #GodBless | Catalino Manio
