We all know kids grow up through many stages. Some things give kids a sense of accomplishment, one of which is the first time they learn to tie their own shoes. This gives kids a sense of independence: Look. I can do the things my mum and dad can do too. Tying shoes may be difficult for kids, but it's something adults can do with their eyes closed. It mainly has three key steps:

1. Cross the laces and tie a knot;

2. Pull one side of the laces to form a loop;

3. Finally, wrap the other side of the laces around the loop and pull it up to form a second knot.

The shoes are then tied, but after a few laps, you will find that some people's shoelaces are particularly easy to untie, while others' shoelaces are always firm and reliable. Look closely, the bow on the shoelaces of this type of friend is always straight, and the knot will not tilt to either side of the shoe. Why is that? Mathematicians have conducted rigorous research on this.
