John Bell and Bell’s Theorem
John Stewart Bell (1928-1990), a truly deep and serious thinker, was one of the leading physicists of the 20th century. He became famous for his discovery that quantum mechanics implies that nature is nonlocal, i.e., that there are physical influences between events that propagate faster than light. From 1960 until his death Bell worked at CERN in Geneva on the physics of particle accelerators,...

متن کاملJohn Bell: a Canadian at the top of UK academic medicine.
What with the knighthood, the Regius Chair of Medicine at Oxford University, and the Presidency of the Academy of Medical Sciences, to ask John Bell if being a Canadian by birth—and still very much by accent—has hindered his UK medical career would be faintly absurd. So, conversely, has it brought any advantages? Yes, he says. For one thing he’s sidestepped traditional British pigeonholing base...
متن کاملQuantum algebra of N superspace Nicolás Hatcher
We identify the quantum algebra of position and momentum operators for a quantum system bearing an irreducible representation of the super Poincaré algebra in the N > 1 and D = 4 superspace both in the case where there are not central charges in the algebra and when they are present. This algebra is noncommutative for the position operators. We use the properties of superprojectors acting on th...
متن کاملCaroline Hatcher Senta Sharp - Final Paper.PDF
While there has been considerable recent focus on the ways in which consulting practice makes the consultant “invincible” (Berglund & Werr, 2000; Clark & Salaman, 1998), the position of the novice student consultant has been a relatively unexamined phenomenon. Successful consulting practice relies on the consultant’s development of a credible and authoritative personal style, the performance of...
