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.

Why do we remember the past and not the future? Untangling the connections between cause and effect, choice, and entropy.

Can Time Be Saved From Physics?
Philosophers, physicists and neuroscientists discuss how our sense of time’s flow might arise through our interactions with external stimuli—despite suggestions from Einstein's relativity that our perception of the passage of time is an illusion.

Thermo-Demonics
A devilish new framework of thermodynamics that focuses on how we observe information could help illuminate our understanding of probability and rewrite quantum theory.

Gravity's Residue
An unusual approach to unifying the laws of physics could solve Hawking's black-hole information paradox—and its predicted gravitational "memory effect" could be picked up by LIGO.

Could Mind Forge the Universe?
Objective reality, and the laws of physics themselves, emerge from our observations, according to a new framework that turns what we think of as fundamental on its head.

Video Description

Quantum entanglement - which Einstein called "spooky action at a distance" - is one of most prominent and mind boggling features of quantum mechanics. To image the effects of entanglement directly, we created in our experiment a pair of entangled photons. The video shows images of single photon patterns, recorded with a triggered intensified CCD camera, where the influence of a measurement of one photon on its entangled partner photon is imaged in real-time. In our experiment the immediate change of the monitored mode pattern is a result of the polarization measurement on the distant partner photon.

Great video. Too brief, I think some additional explanations would do good, but it was excellent.

I watched, commented and rated earlier your video. If you have time, I would appreciate if you will watch and rate my videos The puzzle of quantum reality and Can a black hole keep a secret?.

Best regads,

This is a very interesting demonstration! Like Cristi, I would have enjoyed more explanation. But it was fascinating to see a video of the entanglement relationship. Thank you and good luck!

Cheers

Nice!

This was fun to watch and informative Robert, Mario, and Anton. As with other commenters, I'd have liked to see a little more content. It is kind of neat, though, that the short demonstration shows all by itself that strong correlations are taking place - which can be explained by entanglement, and are hard to explain otherwise (though not impossible). When people see it for themselves, however, the visual evidence has an impact that explanations don't.

All the Best,

Jonathan

I am hoping you will have time to rate and comment on my video..

Can the Mandelbrot Set help us understand the Cosmos?

I spoke with you briefly at FFP11 in Paris, Prof. Zeilinger, and as then I wish you continued success in your research.

Regards,

Jonathan
