Andrey Koval's List: Causality, Randomness, and Chance

• quantum mechanics cannot give exact results, but only the probabilities for the occurrence of a variety of possible results.

  • knowing position of particles = control every TTV

  • This implies, that a given state does not have a predetermined effect, but a distribution of effects each with specific probabiliity of occurance.
    In reverse, when we observe an effect, we must understand how this effect and its probability of occurence fits into the distribution of effects for this particular given state (condition)
• future motion of a particle

  • Effect
• present   position and momentum and all of the forces acting upon it

  • condition, the controlled environment of experiment
• One cannot calculate the precise future motion   of a particle, but only a range of possibilities for the future motion   of the particle. (However, the probabilities of each motion, and the distribution   of many particles following these motions, could be calculated exactly   from Schrödinger's wave equation.)

  • Let's say we know the "present position, momentum, and all of the forces actiing upon the particle" in a given two-dimentional space.
    
    A. What is a population of a possible "future motion of the particle" (effect, outcome)? - Q. It would belong to this two dimentional space.
    
    
    The distribution of probabilitieswould be continous, but any point in this space would be specific outcome

• "relativity and quantum mechanics have forced physicists to abandon these assumptions as exact statements of what happens at the most fundamental levels, but they remain valid at the level of human experience."

• still incompletely known principles of causation that govern the universe

  • Ha! I told you so!
• Three academic disciplines have addressed questions about causality: theoretical physics has the most detailed theories of causation with the most stringent criteria of accuracy and predictive power; philosophy has been proposing and analyzing notions of causality since the time of Aristotle; and artificial intelligence has been developing theories of causality intended to simulate intelligent behavior from the insect level to the human level and perhaps beyond.

  • wtf??? The branch of science that studies the causality directly, empirically, and primarily - quantitative methods - is not even mentioned!
• Three academic disciplines
• they remain valid at the level of human experience
