By IAN DURHAM
In all the talk of the multiverse that gets tossed around these days, there's a subtle but important point that is often lost: there are really two completely different notions of a multiverse. What one thinks of when someone utters the word...

The Physics of What Happens Grantees
By BRENDAN FOSTER
This past winter, FQXi announced it's fifth Large Grant program, on the topic of The Physics of What Happens – a call for proposals for research and outreach projects on "Events". I am happy to announce that from an initial group of almost 250...

Ultimate Reality
The Race to Replace the Kilogram
By ZEEYA MERALI
Thanks to Steve Agnew for suggesting that we open a thread based on a new Scientific American article about the "long-running effort to ditch the decaying, 19th-century artifact that defines the kilogram," by Tim Folger.

The article is...

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...
