friends, we know that fermions must be described by antisymmetric and bosons by symmetric wavefunctions. but i was wondering why a particle of certain class behaves like that for ever? ie. say, an electron will never behave like a boson ?? my book says that there is a spin statistics theorem that ensures that this be so. ie. spin determines the statistics. but thinking this again, when i consider one dimensional problems, no spin can arise, yet i have never heard of a boson electron in one dimension?? i just hope i am not appearing mad here!!
