### Giuseppe Peano

On Saturday I bought
for 2 euros
at the mercatino of Lavello a little book by Giuseppe Peano of numerical tables. It has an interesting preface by Peano.

I suppose Peano is best known for axiomatizing the natural numbers. He introduced the set theory symbols $\epsilon$, $\subset$, $\cap$, $\cup$.

The cover of the little book:
