21 ideas
15970 | People generalise because it is easier to understand, and that is mistaken for deep philosophy [Feynman] |
19125 | If we define truth, we can eliminate it [Halbach/Leigh] |
19128 | If a language cannot name all objects, then satisfaction must be used, instead of unary truth [Halbach/Leigh] |
19120 | Semantic theories need a powerful metalanguage, typically including set theory [Halbach/Leigh] |
19127 | The T-sentences are deductively weak, and also not deductively conservative [Halbach/Leigh] |
19124 | A natural theory of truth plays the role of reflection principles, establishing arithmetic's soundness [Halbach/Leigh] |
19126 | If deflationary truth is not explanatory, truth axioms should be 'conservative', proving nothing new [Halbach/Leigh] |
19129 | The FS axioms use classical logical, but are not fully consistent [Halbach/Leigh] |
19130 | KF is formulated in classical logic, but describes non-classical truth, which allows truth-value gluts [Halbach/Leigh] |
19121 | We can reduce properties to true formulas [Halbach/Leigh] |
19122 | Nominalists can reduce theories of properties or sets to harmless axiomatic truth theories [Halbach/Leigh] |
9410 | Physical Laws are rhythms and patterns in nature, revealed by analysis [Feynman] |
24162 | Planck introduced the idea that energy can be quantized [Baggott] |
21731 | Fields can be 'scalar', or 'vector', or 'tensor', or 'spinor' [Baggott] |
21730 | A 'field' is a property with a magnitude, distributed across all of space and time [Baggott] |
24163 | Free electrons have clouds of virtual particles, arising from field interaction [Baggott] |
18530 | Nobody understands quantum mechanics [Feynman] |
24161 | Thermodynamics sees nature as a continuous flow of energy, as radiation and as substance [Baggott] |
21732 | The current standard model requires 61 particles [Baggott] |
24160 | Particle measurements don't seem to reflect their reality [Baggott] |
17707 | We should regard space as made up of many tiny pieces [Feynman, by Mares] |
