Tel Aviv University Hello everyone, Next week we will have a special colloquium talk by Paul Busch (University of York), as part of the TIDY Distinguished lecture series in Mathematical Physics. The details are appended below. Please note the different day, time and room. The usual Monday colloquium is canceled due to the Holocaust Remembrance Day. For information about future colloquia, see <http://www.math.tau.ac.il/~ostrover/colloquium/colloq2012.html> Yours, Yaron TIDY Distinguished lecture in Mathematical Physics Tuesday, 9/4/2013, 11:10, Schreiber 008, Tel Aviv University. Tea and coffee at 11:00, same room. Speaker: Paul Busch (University of York) Title: Quantum Uncertainty - in All Its Guises Abstract: The Uncertainty Principle, conceived by W. Heisenberg in 1927, epitomises the fundamental philosophical implications of quantum mechanics and its radical departure from classical physics. For decades, there has been an air of vagueness and perhaps even mystique around its formulation and interpretation, which may have contributed to the media hype in 2012 when it was announced that the principle had been experimentally violated. In this lecture I survey precise mathematical formulations of Heisenberg's principle in all its guises as a statement about (a) uncertainties, (b) unsharpness, (c) measurement inaccuracies, and (d) disturbance due to measurement. Recent claims about the failure of the principle are shown to be untenable and found to have arisen from the unwarranted extrapolation of classical physical intuitions about measurement inaccuracies. --------------------------------------------------------- Technion Math Net-2 (TECHMATH2) Editor: Michael Cwikel <techm@math.technion.ac.il> Announcement from: <ostrover@post.tau.ac.il>
