Sustaining Ukraine’s Breakthrough

NEW YORK – Following a crescendo of terrifying violence, the Ukrainian uprising has had a surprisingly positive outcome. Contrary to all rational expectations, a group of citizens armed with not much more than sticks and shields made of cardboard boxes and metal garbage-can lids overwhelmed a police force firing live ammunition. There were many casualties, but the citizens prevailed. This was one of those historic moments that leave a lasting imprint on a society’s collective memory.

How could such a thing happen? Quantum mechanics offers a fitting metaphor. Physicists know that subatomic phenomena can manifest themselves as both particles and waves; similarly, human beings may behave both as individual particles and as components of a larger wave. In other words, the unpredictability of historical events like those in Ukraine has to do with an element of uncertainty in human identity.
