In physics and mathematics, mirror symmetry is a surprising relation that can exist between two CalabiYau manifolds. It happens, usually for two such sixdimensional manifolds, that the shapes may look very different geometrically, but nevertheless they are equivalent if they are employed as hidden dimensions of string theory. More specifically, mirror symmetry relates two manifolds M and W whose Hodge numbers The willingness to question previously held truths and search for new answers resulted in a period of major scientific advancements, now known as the Scientific Revolution. ...

are swapped; string theory compactified on these two manifolds can be proved to be lead to identical physical phenomena. The discovery of mirror symmetry is connected with names such as Brian Greene, Ronen Plesser, Philip Candelas, Monika Lynker, Rolf Schimmrigk and others. Andrew Strominger, ShingTung Yau, and Eric Zaslow have showed that mirror symmetry is a special example of Tduality: the CalabiYau manifold may be written as a fiber bundle whose fiber is a threedimensional torus. The simultaneous action of Tduality on all three dimensions of this torus is equivalent to mirror symmetry.

Mirror symmetry allowed the physicists to calculate many quantities that seemed virtually incalculable before, by invoking the "mirror" description of a given physical situation, which can be often much easier. Mirror symmetry has also become a very powerful tool in mathematics, and although mathematicians have proved many rigorous theorems based on the physicists' intuition, a full mathematical understanding of the phenomenon of mirror symmetry is lacking. One possible mathematical framework is provided by the homological mirror symmetry conjecture. Homological mirror symmetry is a mathematical conjecture by Fields medalist Maxim Kontsevich that seeks a systematic mathematical explanation for a phenomenon called mirror symmetry first observed by physicists. ...
