7903 | The six perfections are giving, morality, patience, vigour, meditation, and wisdom [Nagarjuna] |
Full Idea: The six perfections are of giving, morality, patience, vigour, meditation, and wisdom. | |
From: Nagarjuna (Mahaprajnaparamitashastra [c.120], 88) | |
A reaction: What is 'morality', if giving is not part of it? I like patience and vigour being two of the virtues, which immediately implies an Aristotelian mean (which is always what is 'appropriate'). |
2685 | The Greek 'philia' covers all good and fruitful relationships [Cooper,JM] |
Full Idea: The Greek 'philia' is much wider than our "friendship"; it includes family relationships, and business relationships and membership of institutions. | |
From: John M. Cooper (Aristotle on Friendship [1977], p.301) |
21731 | Fields can be 'scalar', or 'vector', or 'tensor', or 'spinor' [Baggott] |
Full Idea: Fields can be 'scalar', with no particular direction (pointing, but not pushing or pulling); or 'vector', with a direction (like magnetism, or Newtonian gravity); or 'tensor' (needing further parameters); or 'spinor' (depending on spin orientation). | |
From: Jim Baggott (Farewell to Reality: fairytale physics [2013], 2 'Quantum') | |
A reaction: [compressed] So the question is, why do they differ? What is it in the nature of each field the result in a distinctive directional feature? |
21730 | A 'field' is a property with a magnitude, distributed across all of space and time [Baggott] |
Full Idea: A 'field' is defined in terms of the magnitude of some physical property distributed over every point in time and space. | |
From: Jim Baggott (Farewell to Reality: fairytale physics [2013], 2 'Quantum') | |
A reaction: If it involves a 'property', normal usage entails that there is some entity which possesses the property. So what's the entity? Eh? Eh? You don't know! Disappointed... |
21732 | The current standard model requires 61 particles [Baggott] |
Full Idea: The current model requires 61 particles: three generations of two leptons and two flavours of quark, in three different colours (making 24); the anti-particles of all of these (48); 12 force particles (photon, W1, Z0, 8 gluons), and a Higgs boson. | |
