Quantum Theory
... Many new subatomic particles have been discovered. There are three families of particles. Each family contains two of the quarks, an electron (or one of its cousins), and one of the neutrinos. These are the building blocks of all matter. ...

... Our understanding of string theory is still in its infancy. In most cases, we only know how to expand physical quantities in a power series in the string coupling constant, ~. Each term in the power series is given by a sum over Riemann surfaces (the string worldsheet) of a given genus. Different sp ...
