Planck's Quantum Theory - Lumen Learning

Planck's Quantum Theory . Learning Objective. Calculate the energy element E=hv, using Planck's Quantum Theory; Key Points. Until the late 19th century, Newtonian physics dominated the scientific worldview. However, by the early 20th century, physicists discovered that the laws of classical mechanics do not apply at the atomic scale.

Quantum state - Wikipedia

In quantum physics, a quantum state is the state of an isolated quantum system.A quantum state provides a probability distribution for the value of each observable, i.e. for the outcome of each possible measurement on the system. Knowledge of the quantum state together with the rules [clarification needed] for the system's evolution in time exhausts all that can be predicted about the system's ...

Quantum Field Theory (Stanford Encyclopedia of Philosophy)

Quantum Field Theory (QFT) is the mathematical and conceptual framework for contemporary elementary particle physics. In a rather informal sense QFT is the extension of quantum mechanics (QM), dealing with particles, over to fields, i.e. systems with an infinite number of degrees of freedom.

Title: Founding quantum theory on the basis of consciousness

Abstract: In the present work, quantum theory is founded on the framework of consciousness, in contrast to earlier suggestions that consciousness might be understood starting from quantum theory. The notion of streams of consciousness, usually restricted to conscious beings, is extended to the notion of a Universal/Global stream of conscious flow of ordered events.
