The mm and submm wavelengths sample the energy band where the bulk of the cool universe is radiating its energy. With the construction of sensitive interferometers at these wavelengths, we can study many important problems in astrophysics. The Submillimeter Array (SMA) has been in operation on top of Mauna Kea since 2004. It now produces exciting science on a variety of subjects, including comets, forming stars, protoplanetary disk, jets, and galaxies at high redshifts. The rich interstellar spectrum at submm wavelengths and the strong dust continuum emission allow us to study the molecular environment, the powering source, and the magnetic fields in these sources. The Atacama Large Milllimeter/submillimeter Array, now under construction in Chile, will be even more powerful, and will reveal much of the universe which could not be seen before.
