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.

FQXi's essay contests are always set up as a challenge for our community to push back on the boundaries of our understanding. This year was no different, as we asked you to decide how something could be undecidable, compute what we would find uncomputable, and predict where we will find the unpredictable. As ever the response to the call was impressive. After a long period of analysis and deliberation our panel have returned their verdict:

Unable to separate the top two candidates, the panel elected to jointly award first place to Markus Mueller for "Undecidability and unpredictability: not limitations, but triumphs of science" , and Klaas Landsman for "Undecidability and indeterminism" . The panel were impressed by the deep philosophical implications of Landsman's work, and the clear logical writing displayed by Mueller.

Taking a second place prize is David Wolpert and David Kinney's "Noisy Deductive Reasoning: How Humans Construct Math, and How Math Constructs Universes" . The panel cited the discussion of the role of mathematicians as imperfect reasoners as novel and interesting.

Discretionary prizes were awarded to Rick Searle's "Computational Complexity as Anthropic Principle" with the panel noting the entertaining literary device of an imagined conversation between Laplace, Champollion and a mechanical Oracle, and to Jochen Szangolies's "Epistemic Horizons: This Sentence is 1/√2(|True> + |False>)" for a creative approach to the problem.

Thank you to our sponsors, The Fetzer Franklin Fund and The Peter and Patricia Gruber Foundation for making this happen. We also thank our anonymous judging panel for the hard work they put in, and congratulate our winners. And finally, thanks to everyone who entered the contest. We hope to see you again in the next contest soon!

For a full set of winners with third and fourth place please see the winners list

Congratulations to all the winners!

I recall enjoying several of your essays. Some of my favorites were overlooked. I can't say I got to read all of the ones that turned up in the winner's circle, however.

Thanks to everyone who participated, for making it enjoyable. I really do enjoy the engaging debates. I'm not one of those folks who is just looking for appreciation, because I want to understand things on a deeper level.

So it is disappointing when some of the folks who end up winning choose not to engage with folks like myself. I think they would get something out of reading my essay, but many in these contests are very insular. That I don't like so much.

Best to All,

Hello Jonathan, hope you are well, I am understanding your words. I asked me if you could help me also in this project of global collaboration, the aim being to create concrete solutions adapted to our global system to optimise what we can improve. The aim is to convice this UN and make a win win for all. Hope you could put some ideas , I beleive strongly that it is important and that we must try to solve and FQXi and thinkers seems essential to reach this aim. take care, regards

Congratulations to the winners. I must confess that I didn't evaluate any of the winners. They have quite impressive credentials and from what I understood in the abstracts, challenging concepts. I most likely scanned several and with my meager math background went on. Like Jonathan, I have experienced evaluating winners in several past contests and most did not return the favor. Of course, some did. But under the circumstance, I value these contests and the opportunity to exchange ideas. I have learned a great deal from participants in the contest and hope to continue.

A big congrats to the winners and to everyone who participated! As a first timer submitting an article, I must say I was impressed by the diversity and originality of ideas submitted and the thought provoking topic selected by FQXi.

One suggestion I might offer for future contests is to add an "engagement" prize for one or more individuals who are especially responsive in replying to posts about their article and offering constructive feedback to other articles (but not necessarily rating their articles in return). This might help encourage healthy dialogue while discouraging the "I rated yours so you should rate mine" expectation.

Wish I could decide the next essay topic! Topics I would suggest include:

- Quantum gravity

- Is there a theory better than string theory?

- What theory would best unify QM with GR?

- What is the connections between wave functions and gravitons?

- Are the gravitons the foundation carriers of the physics constants?

- Does a gravitational propulsion experiment exist?

- Are the Einstein equations a special case for gravity?

- Forget a theory of Everything, is there a theory that will lead to new technology?

Hi Jason, lol Is there a theory better than string theory?, yes of course, the 3D quantum spheres but of course for this, the lobbies of strings , the universities and the strings theorists must less insist about the main origin of our physicality, they consider all that our geometries, topologies, matters come from fields , it is a fashion in fact because they had not an other theory, but these coded particles spherical turn, are in motions and oscillate ......

An other paramter is this vanity , all we are persuaded and it is difficult to change a line of reasoning, imagine all these Phd and professors having worked so many years in the maths of strings, and me I arrive with my small coded quantum spheres, I am a problem in fact and I am conscious of this, the vanity and the money are against me lol

instead to accelerate the process of evolution of discoveries, unfortunally this vanity decreases it , the competition is well but the points of equilibrium also like the complementarity ....

It is known to all that sometimes light seems to acting as wave and sometimes as like particle that means wave-particle duality. But in our present dissertation we considered that a kind of invisible light rays emerges by maintaining the wave-wave duality (firstly we imagined as an electromagnetic-like ocean may formed by the explained new energy sources beyond our Physical Universe and secondly the said ocean of new kind electromagnetic-like energy field force created after unfolding the Physical Universe) constructed by neutrino-like bosons as photon-like quanta from the new energy sources of SU(6), SU(12), SU(24),……etc. after unfolding the Physical Universe through successive symmetry breaking [considering as different layers of Universe] of the Generalized Gaussian Energy group (GGEG) as SU(11)  SU(6)  SU(5)  U(1); SU(23)  SU(12)  SU(11)  U(1); SU(47)  SU(24)  SU(23)  U(1); on. Therefore, there possible to created a new kind of electromagnetic ocean with discrete new energy wave functions within the folding Universe in another phase for the appearance of Fundamental Consciousness as well as we can imagine an ocean of electron with new kind of electromagnetic energies and new strong forces created after unfolding the Physical Universe through phase-like transitions of energies for the creation as Consciousness.

Cordially requested to read my all articles including "PHOTOELECTRIC EFFECTS: HUMAN MIND AND SENSE DATUM" and "How SU-Levels Are Imply Consciousness and Life".
