These markings, which you may have seen, are called eyemarks. On the production line, using optical sensors, machines know where packages need to be compressed, folded, or cut.

13. Why are airplane windows round?

Airplanes initially had square windows. However, two plane crashes occurred in 1953, and the square shape of the windows was considered the cause. Where there are corners, there are weaknesses. Therefore, a square window with four corners has four weak points, making it prone to cracking under pressure. In fact, the pressure difference between the inside and outside of the window is sufficient to cause significant damage. With this in mind, engineers decided to bypass the edges of the window to distribute pressure more evenly.
