Werner Heisenberg, a German physicist suggested that the position and momentum of a particle cannot be simultaneously measured with arbitrarily high precision. 
 ?E  ?t  ?  h / 4 ?            ?x  ?p  ?  h / 4 ?
This is not a statement about the inaccuracy of measurement instruments, nor a reflection on the quality of experimental methods; it arises from the wave properties inherent in the quantum mechanical description of nature. Even with perfect instruments and technique, the uncertainty is inherent in the nature of things.
