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.

The goal basically is to split the airflow so that the air goes away from the top of the wing, but still close to the bottom.
This produces an area of low pressure above the wing, and the normal pressure underneath lifts the wing up into that.
The rounded shape affects how the air moves, and the width of the wing provides surface for the air below to press upwards on.
Submarines do something similar. The round front guides the water away from the hull, which reduces friction and helps the boat move faster.
