There are four forces that aerospace engineers consider when designing an airplane: weight, thrust, drag and lift.
Engineers use these forces to help design the shape of the airplane, the size of the wings, and figure out how many passengers the airplane can carry.
Lift is more complicated than the other forces of weight and thrust, and engineers can design more fuel-efficient airplanes.
In other words, through the use of math and science, we are able to build airplanes that are safe and efficient, even if we don't completely understand the process behind why it works. Ultimately, if aerospace engineers can figure out why the air flows at different speeds depending on which side of the wing it's on, we can design airplanes that use less fuel and pollute less.
