It is impossible to determine simaltancously  the position of velocity  of small mictroscopic particle such as electron , proton or neutron  with accoracy .This is called Heisenberg's uncertainty principal, Malthematically, it is represenites as `Delta x. Delta p  ge (h)/(4pi) Delta x`  is uncertainty  in position `Delta p ` is uncertainty  in momentum
