 The equation is not correct for arbitrary functions. But it is correct
 for any functions in the Hilbert space--square integrable functions. In
 a simple way the function value should go to zero when one of the
 coordinate is infinity.

 the hermiticity of the operator. But I really can not understand it
 mathematically,say, for any two different functions f1 and f2,i doubt the
 following quation holds always
