Principle of Mathematical Induction/Informal Analogy
When the first domino is knocked over, the entire line topples, one after the other.
It follows that if either:
- $(1) \quad$ no domino is knocked over to start with (that is, the basis for the induction does not hold)
- $(2) \quad$ the gap between two dominoes is too large for one domino to knocked over the next one (that is, the induction step does not hold)
