... Deep mathematical reasons require that quantum particles in three dimensions must be either fermions or bosons. In two dimensions, another possibility arises: the factor might be a complex phase. A complex phase can be thought of as an angle. Zero degrees corresponds to the number one; 180 degrees i ...
