20975 | Quantum 'wave collapses' seem to violate conservation of energy [Papineau] |
Full Idea: The conservation of energy is apparently violated by 'wave collapses' in quantum systems. | |
From: David Papineau (Thinking about Consciousness [2002], A 7 n15) | |
A reaction: One could imagine it being a little harder to verify the conservation of energy at the quantum levels, where particles and anti-particles pop in and out of existence. I've been wondering why there is some suspicion of collapses. |
20820 | Time is an interval of motion, or the measure of speed [Posidonius, by Stobaeus] |
Full Idea: Posidonius defined time thus: it is an interval of motion, or the measure of speed and slowness. | |
From: report of Posidonius (fragments/reports [c.95 BCE]) by John Stobaeus - Anthology 1.08.42 | |
A reaction: Hm. Can we define motion or speed without alluding to time? Looks like we have to define them as a conjoined pair, which means we cannot fully understand either of them. |
