# Jacob Bernoulli's tomb in Basel

Jacob Bernoulli was so impressed by the equiangular or logarithmic spiral that he called it the

*spira mirabilis*.

In particular, he was impressed that the curve is "self-similar". That is, any expansion of the curve will produce the same curve.

He wanted it carved on his tombstone with the Latin motto

*Eadem mutata resurgo*[Although changed, I will rise again the same].

Unfortunately, the mason who did the carving misunderstood the instructions and gave him an Archimedean spiral instead.

The inscription can be translated as:

*Jacob Bernoulli*
