1927. An uncertainty principle announced by German physicist Werner Heisenberg melds physics and philosophy. He states that certain pairs of variables describing motion-velocity and position, or energy and time cannot be measured simultaneously with absolute accuracy because the measuring process itself interferes with the quantity to be measured, so while quantum mechanics provides valuable information it is useful only within limits of tolerance since no events can be described with zero tolerance.
