If you are aware of an interesting new academic paper (that has been published in a peer-reviewed journal or has appeared on the arXiv), a conference talk (at an official professional scientific meeting), an external blog post (by a professional scientist) or a news item (in the mainstream news media), which you think might make an interesting topic for an FQXi blog post, then please contact us at forums@fqxi.org with a link to the original source and a sentence about why you think that the work is worthy of discussion. Please note that we receive many such suggestions and while we endeavour to respond to them, we may not be able to reply to all suggestions.

Please also note that we do not accept unsolicited posts and we cannot review, or open new threads for, unsolicited articles or papers. Requests to review or post such materials will not be answered. If you have your own novel physics theory or model, which you would like to post for further discussion among then FQXi community, then please add them directly to the "Alternative Models of Reality" thread, or to the "Alternative Models of Cosmology" thread. Thank you.

Video Description

Most presentations of quantum mechanics focus on one aspect of the subject and often on some oddity, which eludes common sense. This presentation focuses on an overall common sense understanding to enable the average person to see the worth of quantum mechanics in our society today. The goal is to show that quantum mechanics is a tool we use everyday like the machines we all use now. The method is to present observations from people since ancient times to present showing how the work of many formed a sophisticated science. In essence, this traces Aristotle's observation that light is a wave to the wave mechanics of electricity moving through a wire. The intent is to enable a person to say, "I understand quantum mechanics," after viewing this video.

Video Creator Bio

Al Schneider received a B. S. in Physics from Wayne State University, Detroit, Michigan in 1969. Professionally, he was a contract programmer focusing on industrial and scientific projects. His side interests included magic, karate, skiing, and theoretical physics. The interest in theoretical physics focused on special relativity and quantum mechanics. His goal in life is to find the end of the thread that would unwind the rug called universe.

Hi Al

I saw your video ... I saw it all. And I liked it.

As trying to initiate a scientific revolution, I often have to (try) to explain Quantum Mechanics to laymen, so I am always searching for new and simple ways to address the subject.

I did enjoy your didactics.

But I also noticed that you didn't mention the non-realistic and non-local aspects of Quantum Mechanics.

Do you agree that the local realistic part of quantum theory is enough for chemists and engineers to do their jobs? And that they see no practical use for superposition and entanglement?

I will vote for you. Simple. Comprehensive. No nonsense.

Good luck on the contest.

Teresa

I appreciate your post a great deal.

The goal of this article was to provide the layman viewer a real feeling of what quantum mechanics is.

In that vein, I avoided the collapse stuff, entanglement, etc.

Curiously, an acquaintance that had just graduated from college with a physics degree, much of which was about QM, said that he really did not understand what he had studied...

Hi Al,

I love people that get carried away with stuff.

You do not know what local realism is? (shame on me ... I probably should have put something about it in my video ... hehe)

Local realism is the combination of the principle of locality with the "realistic" assumption that all objects must objectively have a pre-existing value for any possible measurement before the...

I have taken some time to review material about entanglement and so on.

I need to devote more time to it but at present I am encountering three problems.

1. In my cursory search for experiments that have demonstrated Bell's theorem, I have not seen any with conclusive results.

2. In reviewing the presentations on the subject I see them begin with the idea that a particle displays weird behavior. Then the presenter goes on to use the weird behavior to explain the phenomena. To me this indicates that what is happening is not understood. Then, that which follows is inaccurate for it is based on non-understanding.

3. I have my own idea of how the universe is structured. This could be a problem for I view these explanations through a lens of my personal understanding.

Presently I am creating a video of my view of the universe. It is tedious. I shall continue to study the present work of entanglement as time permits.

Thank you for the kindness you have shown me.

Al Schneider
