  The Five-hundred-meter Aperture Spherical radio Telescope (FAST) is by far
the largest telescope of any kind ever built. FAST produced its first light in
September 2016 and it is now under commissioning, with normal operation to
commence in late 2019. During testing and early science operation, FAST has
started making astronomical discoveries, particularly pulsars of various kinds,
including millisecond pulsars, binaries, gamma-ray pulsars, etc. The papers in
this mini-volume propose ambitious observational projects to advance our
knowledge of astronomy, astrophysics and fundamental physics in many ways.
Although it may take FAST many years to achieve all the goals explained in
these papers, taken together they define a powerful strategic vision for the
next decade.
