M-theory is a theory in physics that unifies all consistent versions of superstring theory. Edward Witten first conjectured the existence of such a theory at a string-theory conference at the University of Southern California in the spring of Witten's announcement initiated a flurry of research activity known as the second superstring revolution. Prior to Witten's announcement, string theorists had identified five versions of superstring theory. Although these theories appeared, at first, to be very different, work by many physicists showed that the theories were related in intricate and nontrivial ways. Physicists found that apparently distinct theories could be unified by mathematical transformations called S-duality and T-duality. Witten's conjecture was based in part on the existence of these dualities and in part on the relationship of the string theories to a field theory called eleven-dimensional supergravity.

STRING THEORY AND M-THEORY. A MODERN INTRODUCTION. String theory is one of the most exciting and challenging areas of modern theoretical physics.

## String Theory and M-Theory: A Modern Introduction

We review the status of string theory as a quantum theory of gravity. Our emphasis is on outstanding questions and remaining challenges rather then on well-established results and successes. Download to read the full article text.

И он решил не реагировать на сообщение. ГЛАВА 79 Стратмор спрятал пейджер в карман и, посмотрев в сторону Третьего узла, протянул руку, чтобы вести Сьюзан за. - Пошли. Но их пальцы не встретились.

Сьюзан повернулась к тумбочке. На ней стояли пустая бутылка из-под шампанского, два бокала… и лежала записка. Протерев глаза, она натянула на плечи одеяло и прочла: Моя драгоценная Сьюзан.
