弦论的开端：历史素描
The beginning of string theory: a historical sketch
摘要：
在这篇笔记中，我们将跟踪导致弦论形成的思想的历史发展。我们从Veneziano的启发性猜想及其扩展到$N$标量粒子的散射开始，然后我们描述了如何研究其因式分解性质，以确定使弦世界面显现的物理谱，最后我们讨论了如何将Regge轨迹的截距和临界维数的临界值固定为1和26。
英文摘要：
In this note we follow the historical development of the ideas that led to the formulation of String Theory. We start from the inspired guess of Veneziano and its extension to the scattering of $N$ scalar particles, then we describe how the study of its factorization properties allowed to identify the physical spectrum making the string worldsheet manifest and finally we discuss how the critical values of the intercept of the Regge trajectory and of the critical dimension were fixed to 1 and 26.
