The Standard Model (SM) provides a highly successful description of strong, weak and electromagnetic interactions at present energies. In combination with Einstein's general relativity, it helps lay the foundation of another successful theory, the hot big bang cosmology. Some recent attempts to go beyond this theoretical framework will be discussed, necessitated in part by some exciting experimental discoveries, namely neutrino oscillations, existence of non-baryonic dark matter, CMB anisotropy,etc.
