Heisenberg had forgotten the entire accursed debate about particles and waves,andhad once more clung to numbers to find his path. Analysing Schrodinger39;s mathematics and his own,hehad discovered that certain properties of a quantumobject,such as its position and quantity of motion,werecoupled,and the relationship between them evincedstrange properties.The more precisely the one wasidentified,the more uncertain the other became.If,for example,the exact location of an electron was established with certainty,arresting that particle in itsorbit like an insect impaled on a pin,then its velocitybecame utterly undefined;it might be immobile ormoving at the speed of light,and there was no way ofknowing which.The opposite was true as well.If the electron was endowed with a set quantity of motion,it...
