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...

Retrocausality, Terrorism, and How to Write...

The latest edition of the podcast is now up. (For those expecting our regular December countdown of the year’s top physics stories with Ian Durham, do not fear: I will be posting that too, later this month.)

I recorded a couple of the...

We Are All Connected
By BRENDAN FOSTER
Can you write a song about physics that is actually a good song? Not a joke song or a spoof song; not a song whose only purpose is to teach you the parts of an equation. A song that is on its own simply a good song, but that is also somehow about...

Ultimate Reality
Alternative Models of Reality
By ZEEYA MERALI
If you have an unconventional, alternative model of reality, then this is the place to discuss it. (This is for contributors who have preliminary ideas and would like feedback, but do not have an academic paper or arXiv preprint and have not given a...

A new thread to discuss an issue suggested by Alex Rhatushnyak (thank you).

Alex's summary follows:


At many complexity levels there seems to be two fundamental classes of
