The three merry roads to time asymmetry

Yes.

**References should connect readers to full texts, and therefore favor OA editions.**

A nice argument from Patrick Dunleavy: "What is the essential purpose of academic referencing? ...A completely out of date answer dominates current practice — namely...[directing readers] to the same precise sources and pages that you yourself used in constructing an argument or a case....Referencing should instead be about directly connecting readers to the full text of your sources, ideally in a one-stop way....In other words, modern referencing is not about pointing to some source details for books that cost a small fortune and are buried away in some library where the reader is not present; still less about pointing to source details for an article in a pay-wall journal to which readers do not have access....With open access spreading now we can all do better, far better, if we follow one dominant principle. Referencing should connect readers as far as possible to open access sources, and scholars should in all cases and in every possible way treat the open access versions of texts as the primary source...."

Serious Bug: mathematics rendered by javascript does not appear on feedly, e.g. on wordpress blogs with a LaTeX plugin, or other blogs with a MathJax script. To reproduce, go to any blog with this kind of mathematics (example: Terry Tao's blog, http://terrytao.wordpress.com/2014/03/19/metric-entropy-analogues-of-sum-set-theory/ ). Notice the math. Now open the post in Feedly. Notice the math doesn't appear.

Javascript that turns Latex into readable images is the most common way for bloggers to post about mathematical topics, and so it really makes the Feedly service unusable for the math-types among us. I had to switch to The Old Reader to access them. But I prefer to use Feedly, and would love to come back when the problem is fixed!

Call for Papers, philosophers and physicists interested in time from the perspective of quantum theory. Know somebody who might want to submit?

CFP: "Quantum Time"

28-29 March 2014

Center for Philosophy of Science

817 Cathedral of Learning

University of Pittsburgh

Pittsburgh, PA USA

SUBMISSION REQUIREMENT: 1000-word extended abstract.

EMAIL SUBMISSIONS TO: pittquantumtime14@gmail.com

DEADLINE: October 15, 2013.

NOTIFICATION BY: November 10, 2013.

Many of the problems of time in physics are old and well-known, and their morals for metaphysics have been explored. In this workshop, we propose to attack a newer problem: How is quantum time special? More specifically, this workshop will explore the ways in which quantum theory leads to new insights about the nature of time, and how thinking about the role of time may lead to insights about quantum theory. Topics may include (although they are not limited to) the problem of time in quantum gravity, quantum time observables, temporal symmetry violation, and the unitary and non-unitary implementability of time evolution in quantum theory. We are holding an open call for papers presenting fresh new ideas, of which we can accept up to 6 participants. The participants will join the three invited speakers below. We welcome submissions of 1000 word abstracts from both physicists and philosophers, with the hope that this workshop will provide a useful forum for interdisciplinary engagement.

INVITED SPEAKERS: Abhay Ashtekar, Juan Gonzalo Muga, Laura Ruetsche.

ORGANIZING COMMITTEE: Thomas Pashby, Bryan Roberts, Giovanni Valente
