## Historical Note on Approximate Relations between Pi and Euler's Number/Fanelli's Approximation

Fanelli's approximation is the name coined by $\mathsf{Pr} \infty \mathsf{fWiki}$ to the approximation $\sqrt [9] {10 e^8} = 3 \cdotp 14159 \, 828 \ldots$.

Michele Fanelli abandoned further work on establishing similar correspondences, and in more recent times has contributed towards the literature on the Riemann Hypothesis.
