27. Natural Reality / A. Classical Physics / 2. Thermodynamics / c. Conservation of energy
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.
27. Natural Reality / D. Time / 1. Nature of Time / d. Time as measure
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.
