Easing Uncertainty (IMAGE) ETH Zurich Department of Physics Caption Heisenberg's uncertainty principle limits the precision with which complementary variables can be measured. The uncertainty, however, can be 'spread out' in broad comb-like structures, where each tooth is still relatively sharp, thus enabling precise measurements in a limited range.
