Wandering Towards a Goal: Winners Announcement
By BRENDAN FOSTER
We asked the question: how do mindless mathematical laws give rise to aims and intentions. So how does it happen? Well, we’re not going to just tell you the answer. You’ll have to read it for yourself — in our winning essays, which we are now...

FQXi Essay Contest 2016: Wandering Towards a Goal
By BRENDAN FOSTER
In physics we tend to stick to asking what happened, how did it happen? We like to describe, usually in minute details. We like to use the smallest possible components, “building blocks”, “unit cells".

But there are other ways to think...

By BRENDAN FOSTER
An FQXi mini-grant in 2015 helped fund a project of Member Hyung Choi of Greenville College, on "The nature of light explored through hyper-entanglement". Dr. Choi shared with us the story of his student Shuto Osawa's research journey, at this link....

Ultimate Reality
Tegmark's Mathematical Universe
By ANTHONY AGUIRRE
While he would be too modest to toot his own horn, there's nothing stopping me from pointing out that 'mad Max' has recently put out a very interesting paper on whether all possible formal systems (and the 'physical' universes that some subset of...

Cosmology
Alternative Models of Cosmology
By ANONYMOUS
In cosmology, it is believed that regions of space on `opposite' sides of the universe are too far apart to have ever been causally connected. That is, they are outside each other's `particle horizon'. Consequently, it is difficult to explain the...
