But some of the planned talk, at 5 p.m. in Chapman's Irvine Lecture Hall, will focus on one of his other strange results: that a long series of gentle or "weak" measurements can reveal information many physicists consider off limits, forbidden by the nature of physical reality.
These weak measurements, Aharonov said, suggest that the present is a kind of collision between information from the past and from the future.
And it could well explain another bizarre effect in quantum physics. Subatomic particles can appear to be in two or more places at once; in reality, Aharonov said, a given property of the particle, say, its spin, might be separated from the particle itself.
He calls it it the quantum Cheshire cat effect, a reference both to Lewis Carroll and to a famous physicist, Erwin Schrodinger. - OCR
If an order exists between impetus and event, it might well look like a bridge between past and future.
