Chapter 7 A basic introduction to quantum mechanics

“Fall in love with some activity, and do it! Nobody ever figures out what life is all about, and it doesn't matter. Explore the world. Nearly everything is really interesting if you go into it deeply enough. Work as hard and as much as you want to on the things you like to do the best. Don't think about what you want to be, but what you want to do. Keep up some kind of a minimum with other things so that society doesn't stop you from doing anything at all.”

Schrödinger’s equation:


Blinding you with science already?  Here is a very straight forward explanation of what happens.  It does not explain why it happens but it does explain what happens.  Just tap it into your browser or follow the link.


One explanation deeper explanation of what is going on is Richard Feynman’s explanation, some times called the many worlds or multiverse explanation.  At every moment in time every particle in the universe makes decisions, using the laws of physics, on where “they want” to go.  Each different set of decisions leads to a different universe.

However on the microscopic level most of these very small decisions come back to the same universe.  So particles do not have a position they have a probability wave of positions which we can see in the universe we are in.  In other branching universes the probability wave of positions is different and the electron arrived at a different place.  At the macroscopic level this allows us to have free will and make free choices which have bigger divergence of worlds.

This means you do not calculate a particles position but its probability wave function.  So what you saw in the video was not waves but the waves of probability from the multiverse where electrons chose a lot of different paths to get to the back pane and the sum of those probabilities is the final result in our universe.

When you observe the electron the probability collapses because at the point of observation the electron the electron is either there or not there so there is no chance of the electron being half there and half not there. 

The electron is a particle but it appears to be a wave while in transit and unobserved because it has a probability of being in any position in this universe or in other universes.  It is possible for it to get to anywhere or any when in the universe but the further away from where we expect it to be, the smaller the probability.

When it is next observed again we know where it is.  However in other branched futures in other branches of the multiverse, it could be observed somewhere or some when else.

The fact that particles can travel back in time allows the cosmos to have a feedback loop.  This allows the cosmos to learn.  Please note there are no more simple thinkers than particles at the subatomic level.

This is why Seth Lloyd thinks the Universe is a quantum computer


Occam’s razor suggests that this is not the simplest nor most economic solution.  However, I would point out that the foundation of this understanding of existence is that the Word exists in a purely abstract existence and the whole of existence is our lives are words an abstract construction of words.    So every permutation of every set of words exists.  So every possible Universe must exist and so the multiverse must be the correct explanation as that is the simplest solution.
