We find an identity that expresses the logarithm of the ratio of any two irrational numbers $a, b \gt 1$ via a series whose terms are ratios of elements of the Beatty sequences generated by $a$ and $b$. We also show that Sturmian sequences can be defined in terms of these ratios. Furthermore, we find an identity for such series that bears a superficial resemblance to (a discrete version of) Frullani’s integral.
