Original handout written by Neal Kanodia and Steve Jacobson. One of the most useful data types supplied in the C++ libraries is the string. A string is a variable that stores a sequence of letters or …

String theory builds on the conceptual foundations that have been established in elementary particle physics in the 1970s. It is a quantum theory that aims at reproducing the interaction and symmetry …

A number of more recent topics in string theory are not covered in these notes, including D-branes (except in Appendix C), the AdS/CFT correspondence, M-theory and topological string theory to …

These notes are based on the string theory lecture course by Prof. Amihay Hanany, taught at Imperial College London in 2025. While they broadly follow the structure of the course, at times I decided to …

ng Functionality To retrieve an element of a string, just use [], exac. ly like vectors. In addition, you can iterate through a string ju. t like a vector. The following function, for example, returns the first index of …

The notes have long been out of print, but over the years we had continuous positive feedback from students, who found the book helpful in their attempt to enter string theory. To make the book useful …

Chapter 1 Motivation There are two main motivations for string theory: As an extension ("UV completion") of quantum eld theory, and as a theory of quantum gravity. In this course
