QDear 100 Hour Board,

I learned that an alpha-helical structure (I'm thinking of spiral stairs in particular) is so stable that it doesn't need any supporting structures to keep it up. And as a side question, what's the difference between stairs and staircases?

ADear Volleyball,

The relationship between stairs and a staircase is similar to that between a shelf and a bookcase.   Stairs are held in place by a staircase; the staircase includes the siderails, etc.

If that's your side question, what's your main question?

-Yellow
