Modal interpretations of quantum mechanics admit two kinds of state: physical states, which specify the values of observables on a system, and theoretical states, which specify a probability ...

Measurement postulate is crucial to quantum mechanics. If we measure a quantum system, we can only get one of the eigenvalues of the measured observable, such as position, energy and so on, with a ...

In his criticism of scientists who find Koch's postulates obsolete,1 Todd Miller overlooks one important point. Recruiting volunteers to apply Koch's postulates to diseases such as Ebola fever and ...

THE following is a preliminary report of an investigation performed to test directly, in a terrestrial experiment, the second postulate of special relativity, which states that the velocity of light ...
