Why do airplane wings have round leading edges?

Question

I don’t understand all the internet explanations using terms like “Range of attack” “Stall speed”

I’m trying to understand why it matters that the wing has a blunt front, if just angling a flat sheet slightly upwards should in my theory still lift it up at speed.

Although those round edges intuitively make sense somehow, i just want to understand why they work.

Answer 1

Take a butter knife (to be safe) and “slice” the air. Now try the same with a piece of paper.

Airplane wings are not made of heavy material like solid metal the way the knife is, it’s made of composites and a round shape in the front gives the wing more stability no matter whether the plane is ascending, descending, or turning.
