String Theory

Abstract

I start describing my interaction with Bruno during my thesis and then in his group in Frascati in connection with the calculation of the total cross-section of double bremsstrahlung that, at that time, was considered a good candidate as a monitor reaction for Adone. Then I discuss my transition to S-matrix theory and to the work that brought from the Dual Resonance Model to String Theory. I conclude describing the main results of String Theory in a way that could be followed by non-experts in the field.
