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.

It is with great sadness that we learnt of the death of John Barrow. John was a member of FQXi’s scientific council and contributed in shaping our research direction and focus. John was an accomplished physicist as both researcher and teacher, and played a large part in many successful outreach activities. He was committed to improving the teaching of mathematics at schools, taking on the role of director of the Millennium Mathematics Project, and writing dozens of books for the general public.

John was a central figure in classical cosmology, investigating areas that would prove counter-intuitive or unexpected, such as “big rip” and “sudden” singularities. His academic interests pushed the boundaries of the field - he was also a central figure in understanding the role of anthropic arguments in physics, and together with Frank Tipler wrote the central text on the issue. Just this year he was working on approaches to the fundamental issues - providing a novel method for estimating the entropy of a black hole.

On a personal level, I first met John in 2012 when I went to Cambridge as a postdoc; he was to be my supervisor. He was the driver of a range of fascinating discussions of physics; every week John would suggest a new area to look at citing papers from a remarkably broad array of fields from electrical engineering to philosophy. Beyond that, however, our discussions would consist of his teaching me about aspects of the world of which I wasn’t even aware that I knew nothing. His breadth of knowledge was intimidating - from how to write plays in Italian to the furniture of bishops. He was a fabulous storyteller with a quick wit and keen sense of humour. He was an accomplished athlete; on telling him I was going for a run one day he gave me routes, and times to attempt them in, from his past. I got about half-way through the first one.

John deservedly won a long list of prizes, any one of which would be the highlight of many careers - the Templeton Prize, the Kelvin Prize, the Dirac Medal and many more. He was an excellent physicist, a true renaissance man and fine mentor. We will miss him.

Hi Mr Sloan, I am sad , I liked this scientist, I have read two works from him, the origin of the universe, and theories of everything, he was a great scientist indeed .
