Eccomi di ritorno da Istanbul ( a dire il vero sono tornato qualche giorno fa :D ) con queste banconote, perché in Turchia, i nerd li mettono pure sui soldi!
Sulla prima banconota, possiamo vedere: [i]Aydın Sayılı (* 1913; † 1993 ) was a historian of science[/i]
Sulla seconda: [i]Cahit Arf (11 October 1910 – 26 December 1997) was a Turkish mathematician. He is known for the Arf invariant of a quadratic form in characteristic 2 (applied in knot theory and surgery theory) in topology, the Hasse–Arf theorem in ramification theory, Arf semigroups, and Arf rings.[/i]
