For millennia, humans gazed skyward with envy at birds soaring effortlessly through the air. From the mythical Icarus to Leonardo da Vinci's sketches of flying machines, the desire to conquer the skies has been a persistent dream throughout human history. But it wasn't until the dawn of the 20th century that this ancient ambition finally became reality.

Airplanes soaring through the sky, defying gravity, is a fascinating sight for most of us. So how do airplanes really fly? How is the lift force that keeps an airplane in the air created? Most of us have learned in school or popular science resources that the air flowing over the wing of an airplane flows faster than the air flowing under it, and that airplanes rise due to the pressure difference according to Bernoulli's principle. However, the situation is not that simple in reality.

Air transportation has become an indispensable element of modern societies. With thousands of aircraft landing and taking off every day in the world, airports are designed in a precise order to ensure that these operations can be carried out safely and effectively. One of the most basic elements of this order is the naming of airport runways and the numbers at the beginning and end of the runway.
