On aircraft wings, the bottom is flat and the top is curved. I know this benefits the aircraft by producing lift, but I wish to understand how. I'm told it has something to do with how fluids behave.

    $\begingroup$ Very closely related to What really allows airplanes to fly?, which answers your question and more. $\endgroup$ – Emilio Pisanty Jun 11 '15 at 8:58

    $\begingroup$ Also you might get two different reasons in textbooks as to how the lift is created, thinking about which one is right may teach you a lot about physics. It did for me anyways, best of luck with it. $\endgroup$ – user81619 Jun 11 '15 at 10:56

    $\begingroup$ Please check out the other answers on the site. The flat-bottom-curved-top business is a widely-taught absolutely wrong explanation, and totally fails to explain aerobatic airplanes, which have symmetric airfoils. They fly just as well upside-down as right-side up. Almost any shape can fly, as long as it pulls the air into a downwash. $\endgroup$ – Mike Dunlavey Jun 12 '15 at 1:31
