Designer Eleanor Lutz used high-speed video of five different flying species to create this graphic illustrating the curves swept out in their wingbeats. The curves are constructed from 15 points per wingbeat and are intended more as art than science, but they’re a fantastic visualization of several important concepts in flapping flight. For example, note the directionality of the curves as a whole. If you imagine a vector perpendicular to the wing curves, you’ll notice that the bat, goose, and dragonfly would all have vectors pointing forward and slightly upward. In contrast, the moth and hummingbird would have vectors pointing almost entirely upward. This is because the moth and hummingbird are hovering, so their wing strokes are oriented so that the force produced balances their weight. The bat, goose, and dragonfly are all engaged in forward flight, so the aerodynamic force they generate is directed to counter their weight and to provide thrust. (Image credit: E. Lutz; via io9)

“ The truest form of love is how you behave toward someone, not how you feel about them. ”
There’s this girl at my school and she’s really nice and I remember sometime last year at one point she would carry a clicker around and click it everytime she had a happy thought/something good happened/she laughed etc.
It was always kind of cute how you’d just hear the little click every once in a while throughout class it always made me smile knowing that it was bc something made her feel happy idk
she was training herself to be happy oh my god
