1-2g2t5a There is no such thing as the 'same' instance of a particle at different times - i.e., there is no such thing as speed of 'one instance' in the quantum physics (Heisenberg uncertainty principle)

1-2g2s5 When the instances are fungible, there is no such thing as ‘which’ - histories and individual particles are not perfectly partitioned into instances
1-2g2s2a Quantum mechanical law of motion resembles the law governing the spread of an ink blot (確率分布)

1-2g2t5b The term ‘uncertainty principle’ is doubly misleading because first of all fungibility is a physical fact and not uncertainty of anything, and second of all because it can be derived from more general principle of quantum physics
