String theory is one of the most exciting and challenging areas of modern theoretical physics This book guides the reader from the basics of string
We start with the type IIA action since this theory is closely related to the 11 dimen- sional supergravity In a string theory there are two basic scales

- It is the name of the unknown theory of everything which would combine all five Superstring theories and the Supergravity at 11 dimensions together. The theory requires mathematical tools which have yet to be invented in order to be fully understood. The theory was proposed by Edward Witten.
