physical theory

Physical theory

A physical theory usually involves the attempt to explain a certain class of physical phenomena by deducing them as necessary consequences of other phenomena regarded as more primitive and less in need of explanation. The value of a theory depends on both the success with which it coordinates a wide range of presently known facts and its fertility in suggesting places to look for presently unknown phenomena.

This principle, first proposed 40 years ago by physicist Roger Penrose, keeps sacrosanct an idea -- determinism -- key to any physical theory.
He has won a prestigious PS75,000 Royal Society Wolfson Research Merit Award to run a project involving the mathematical modelling of a physical theory proposed to explain the existence of the Higgs boson, said to give matter its substance, or mass.
Leaving aside which physical theory is the ultimate theory, might another approach be that all of them have something to contribute to the nature of consciousness?
The goal is to complete four research tasks, designed, on the one hand, to make progress on Yau~s conjecture for the Strominger system and, on the other hand, to understand rigorously, in one simple example, a conjectural, fundamental, symmetry of the underlying physical theory, known as (0,2)-mirror symmetry.
If one's physical theory indicates that the best explanation for my own subjective experience, including memories, is that I am a disembodied brain temporarily hallucinating in the void (rather than a real person currently sitting at my desk), that's a problem for one's theory.
But she does briefly discuss black holes' importance in many fundamental aspects of physical theory today, from their role in creating gravitational waves to their connections with the mysteries of quantum physics.
Due to the peculiar yet potent workings of the human mind, a physical theory about the mechanics of the universe on the smallest of scales transforms into a shared imaginary that connects people not only to that universe, but to each other.
If the relevant body of physical theory were falsified and replaced with something better, the physicist in learning the new theories, may simultaneously acquire a new way of seeing old events.

In the technological engineering of communication, it was a decisive step when Shannon (1948) turned entropy--the key term in physical thermodynamics--into a probabilistic measure of the degree of information contained within a message, thereby transforming the physical theory of heat into "cold" mathematical analysis.
The standard scholarly view has been that the latter claim is forced upon the Stoics by their own physical theory (in particular, their view that the cosmos will eventually expand in size).
Physical theory is covered first, giving a detailed explanation of ferrimagnetism and ferrites with mention of semiconductors, nanotechnology, and thin ferrite films in new circulator technologies.
