Avshalom Elitzur takes us deep into the riddles of Quantum Mechanics, and shares his recent discovery, the Quantum Liar Paradox.

Avshalom C. Elitzur has earned his PhD under the supervision of Yakir Aharonov. He is a member of Iyar, The Israeli Institute for Advanced Research. The ElitzurVaidman bombtesting experiment, listed by the New Scientist magazine among "the seven wonders of quantum mechanics," is the single experiment in physics' history that makes one smile.

Elitzur's research spans over quantum measurement, Special and General Relativity and the nature of spacetime. His SpacetimeDynamics hypothesis aspires to attain theoretical physics' holy grail, namely, unifying Relativity and Quantum theories. It describes the quantum interaction as preceding the emergence of the spacetime region within which it "occurs," thereby, hopefully, better accounting for the relativistic and quantum oddities of mass and energy.

Elitzur's other papers include novel contributions to evolutionary theory and to philosophy of mind. He also writes on environmental and moral issues.
