One of the most fascinating principles in quantum mechanics must be Heisenberg's uncertainty principle, which can be briefly stated as follows: every physicM observation cannot be precisely determined without some degree of error or uncertainty. And it is by no means can one use the principle within the limit of certainty region, as will be shown in this Letter. Two of the most important pillars in modern physics must be Einstein's relativity theory and SchrSdinger's contribution to quantum mechanics. Yet, there is a profound connection between these discoveries by means of the uncertainty relationship, in which we shown that the observation of a high-speed object is conceivable if the speed of the observer keeps up with object's speed. 展开更多
