Variable adjective | not consistent or having a fixed pattern; liable to change. In a science experiment, there are three kinds of variables: independent, dependent and controlled. This is one of the first things about science that Senku learns as a kid and has followed that rule until he meets (Full Name) who changes that one rule. She shows him there is a fourth kind of variable: constant. To Senku, science is never about consistency as things are always evolving and changing, yet that doesn't apply to (Name) and he can never understand it. However, maybe it isn't such a bad thing in this stone world where Senku will learn how consistency plays an important role in science.
