Heisenberg&rsquo;s uncertainty principle says you can&rsquo;t simultaneously know a particle&rsquo;s position and momentum with perfect precision. But position and time? That relationship was never spelled out the same way.</p> <p>A team of German researchers just closed that gap. Using attosecond laser pulses and a scanning tunneling microscope, they observed something they&rsquo;re calling the &ldquo;space-time limit&rdquo; of an electron: a fundamental trade-off where better timing precision comes at the cost of spatial localization. The work was published July 3 in <em>Nature Photonics</em>.</p>
