Cordial Deconstruction

Observations from our shared single objective reality in a materialistic, naturalistic, & effectively macro-deterministic universe.

Reply to a Comment on My Schrödinger’s Cat Post

Posted by Karl Withakay on May 1, 2011

Commenter your wrong left the following comment to my Deconstruction post on Flash Forward’s mishandling of the Schrödinger’s Cat thought experiment:

“Ok, you seem to have completely missed the point here. The point of Schrodinger’s cat is precisely about quantum probability, which you have stated, and you seem to have a knowledge of this thought experiment and what it means. The thing that is really getting to me is the fact that the point is still being made in almost exactly the same way, but you are quibbling over the fact that it is not explained fully and mentioned the radioactive isotopes and the Copenhagen interpretation. Surely a 10 minute conversation about this thought experiment would waste time in the programme and really doesn’t matter. The nitty gritty stuff is for scientists, not for people just watching some action on television. Don’t get me wrong I love reading physics as much as any studious person, but it really doesn’t matter in the slightest that he didn’t go into every single little detail regarding the experiment. Stop wasting your time complaining and read more physics, you’re obviously interested in it. Not only that but you’ve wasted my time having to correct your ignorance.”

What follows is my reply to that comment, which I felt was worthy of it’s own post.

It would appear to be you who has completely missed the point and demonstrated your ignorance on the topic.  By substituting a poisoned sardine for the decay of a radioactive isotope, quantum probability has been eliminated from the thought experiment and has been replaced by a regular non-quantum, deterministic event.

Further, when the physicist states that the observer gets to choose whether the cat is alive or dead, that is not quantum physics and the collapse of the quantum waveform, it’s a philosophy of a post modernist subjective reality, dependant on the perception and will of the observer.  In quantum mechanics, the observation of the cat in the original thought experiment collapses the quantum waveform and solidifies the current state of the cat; it does not choose which state the cat is in, which is what the physicist in the TV show said.

The writers completely misunderstood the thought experiment, and got it wrong on two key points.  They replaced a quantum probability with a deterministic event, and then gave the observer a choice in the end state of the cat rather than the observation only being a choice to create the end state of the cat with no ability to choose what that end state was.

It is acceptable to boil a scientific concept like quantum probability and decoherence down to a form the average TV viewer can understand, but only if it remains relatively accurate in the key points.

I have not wasted my time at all, and if you have wasted you time is not my fault.  It would seem that I have either read more physics than you, or I have at least better understood and appreciated the nuances of what I have read.  It also seems that you either failed to pay attention while reading my post, or you were unable to understand they key points of my post.   If by reading this reply you better understand the key points as to why the writers got the thought experiment wrong, then you have not wasted your time at all either.

And by the way, you’ve spelled your name wrong if your intention was to say “you’re wrong” rather than talk about a wrong that I posses.  I normally don’t quibble about simple spelling mistakes, but I would think if someone takes the time to compose a 181 word statement claiming someone  is wrong on a matter of quantum physics, that they would take time to make sure they haven’t confused “your” with “you’re”.  Such a mistake hardly adds to your credibility.
