    [The Fine-structure Constant] quantifies the strength of the electromagnetic interaction between elementary charged particles.

    Why the constant should have this value is not understood, but there are a number of ways to measure its value.

    Sounds like we know what it is, we just don’t know the reason for its value. (Edit: Unless I’m misunderstanding what you mean)
