Single Idea 21181

[filed under theme 27. Natural Reality / A. Classical Physics / 1. Mechanics / c. Forces ]

Full Idea

General Relativity and quantum mechanics are the two great theories in physics today but they give two very different ideas for how forces work.

Gist of Idea

Relativity and Quantum theory give very different accounts of forces

A Reaction

Relativity says it is space curvature, and quantum theory says it is particle exchange? But is there a Relativity account of the strong nuclear force?

The 20 ideas from 'The Particle Zoo'

21181 Relativity and Quantum theory give very different accounts of forces [Hesketh]
21180 Electrons are fundamental and are not made of anything; they are properties without size [Hesketh]
21182 Quantum mechanics is our only theory, and is very precise, and repeatedly confirmed [Hesketh]
21184 Physics was rewritten to explain stable electron orbits [Hesketh]
21183 Thermodynamics introduced work and entropy, to understand steam engine efficiency [Hesketh]
21186 Quarks rush wildly around in protons, restrained by the gluons [Hesketh]
21185 Colour charge is positive or negative, and also has red, green or blue direction [Hesketh]
21188 Quarks and leptons have a weak charge, for the weak force [Hesketh]
21189 Electrons may have smaller components, bound by a new force [Hesketh]
21187 Virtual particles can't be measured, and can ignore the laws of physics [Hesketh]
21190 'Space' in physics just means location [Hesketh]
21191 Photons are B and W° bosons, linked by the Higgs mechanism [Hesketh]
21192 Neutrinos only interact with the weak force, but decays produce them in huge numbers [Hesketh]
21193 The universe is 68% dark energy, 27% dark matter, 5% regular matter [Hesketh]
21194 The Standard Model omits gravity, because there are no particles involved [Hesketh]
21195 In Supersymmetry the Standard Model simplifies at high energies [Hesketh]
21198 If a cosmic theory relies a great deal on fine-tuning basic values, it is probably wrong [Hesketh]
21196 To combine the forces, they must all be the same strength at some point [Hesketh]
21197 Standard Model forces are one- two- and three-dimensional [Hesketh]
21199 Spinning electric charge produces magnetism, so all fermions are magnets [Hesketh]
