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 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.

First Things First: The Physics of Causality
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.

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.

What a great way to wrap up the summer. Cassini finds liquid hydrocarbons on Titan, making it the only other place we know of with natural lakes and charging up the search for life outside Earth. Phoenix Lander finds water ice in the Martian soil, adding credence to the suspicion that microbes might once have evolved there. And, oh yeah, an Apollo astronaut admits that the government has...

On the subject of extra terrestrials, Guillermo Lemarchand has been writing about how we might build a universal language, or Lingua Cosmica, to communicate with aliens. (In “Close Encounters...,” of course, they did it with music.)

Lemarchand leads the SETI project at the Argentine Institute for Radio Astronomy. He notes that the different languages that humans speak can influence and restrict (or enhance) the kinds of thoughts they have and the way that they perceive the world. That difference would be amplified when considering how humans could communicates with aliens, to the point that we may never be able to recognize the way their intelligence manifests itself, or recognize, decode, and respond to their efforts at communication.

In the end, he suggests using symmetry, and in particular, communication based on the golden section, which is aesthetically pleasing to humans—appearing in nature and in art, architecture, and music—and could be universally appealing.

Excuse me, the first picture is right over the first bit of text, so I can't read it. This is the second time this happens. Is it my computer that does this or is it this blog that's wrong? Either way, can it be fixed?
