Charge conjugation invariance of the Spectator Equations
In response to recent critcism, we show how to define the spectator equations for negative energies so that charge conjugation invariance is preserved. The result, which emerges naturally from the application of spectator principles to systems of particles with negative energies, is to replace all factors of the external energies Wi by √ W 2 i , insuring that the amplitudes are independent of t...
متن کاملElectromagnetic interactions for the two - body spectator equations
This paper presents a new non-associative algebra which is used to (i) show how the spectator (or Gross) two-body equations and electromagnetic currents can be formally derived from the Bethe-Salpeter equation and currents if both are treated to all orders, (ii) obtain explicit expressions for the Gross two-body electromagnetic currents valid to any order, and (iii) prove that the currents so d...
متن کاملFacing the Spectator
We investigated the familiar phenomenon of the uncanny feeling that represented people in frontal pose invariably appear to "face you" from wherever you stand. We deploy two different methods. The stimuli include the conventional one-a flat portrait rocking back and forth about a vertical axis-augmented with two novel variations. In one alternative, the portrait frame rotates whereas the actual...
متن کاملExamining the Spectator Experience
Drawing on a model of spectator understanding of error in performance in the literature, we document a qualitative experiment that explores the relationships between domain knowledge, mental models, intention and error recognition by spectators of performances with electronic instruments. Participants saw two performances with contrasting instruments, with controls on their mental model and und...
متن کاملThe Actor - Spectator - Producer Pattern
A virtual environment is a computer-generated world accessible to a (human) user through input/output devices. It is similar to a traditional simulation but with an emphasis on threedimensional graphics, immersion and real-time interaction. A distributed virtual environment has several participants interacting simultaneously with the virtual world. An example application would be a surgical tra...
