1 << 32在Go中是什么意思？

What does 1 << 32 mean in Go? If I understand correctly it means 2^32. Or am I mistaken? And if my opinion above is right, what does this code do?

min := int(^uint(0) >> 1)

    1 is shifted 32 times.

    Shift is a bitwise operation. See: http://en.wikipedia.org/wiki/Logical_shift
