Are quantum particles objects?
It is widely believed that particles in quantum mechanics are metaphysically strange; they are not individuals (the view of Cassirer 1956), in some sense of the term, and perhaps they are not even objects at all, a suspicion raised by Quine (1976a, 1990). In parallel it is thought that this difference, and especially the status of quantum particles as indistinguishable, accounts for the differe...
متن کاملShould you show me the money? Concrete objects both hurt and help performance on mathematics problems
How do concrete objects that cue real-world knowledge affect students’ performance on mathematics word problems? In Experiment 1, fourthand sixth-grade students (N 1⁄4 229) solved word problems involving money. Students in the experimental condition were given bills and coins to help them solve the problems, and students in the control condition were not. Students in the experimental condition ...
متن کاملQuantum Gravitational Force Between Polarizable Objects.
Since general relativity is a consistent low energy effective field theory, it is possible to compute quantum corrections to classical forces. Here we compute a quantum correction to the gravitational potential between a pair of polarizable objects. We study two distant bodies and compute a quantum force from their induced quadrupole moments due to two-graviton exchange. The effect is in close ...
متن کاملThe Discontinuous Spatiality of Quantum Mechanical Objects
The quantum mechanical wave-particle dualism is analyzed and criticized, in the framework of Reichenbach’s concepts of phenomenon and interphenomenon. It is suggested that the dual pictures be de-emphasized in the study of quantum theory, and that a qualitative picture of atomic processes need not make use of them. In this connection we stress a view of the electron and other such “particles” a...
متن کاملQuantum Torsors and Hopf-galois Objects
We prove that every faithfully flat Hopf-Galois object is a quantum torsor in the sense of Grunspan.
