Trick or Truth? — Essay Contest 2015
By BRENDAN FOSTER
Physics and mathematics -- It seems impossible to imagine the history of either one without the other. For gravity theory alone, we see so many examples of this -- from Newton creating calculus, to Einstein mining differential geometry.

Detecting Dark Matter Using Space-Based Quantum...
By ZEEYA MERALI
I’m lucky enough to be attending a COST Action workshop on quantum foundations currently taking place in Erice, Italy, with lots of FQXi folk in attendance. (Thank you to the organisers, FQXi’s Angelo Bassi, Catalina Oana Curceanu and Detlef...
Collapsing Physics, Celebrating Ghirardi
By ZEEYA MERALI
Yesterday afternoon at the quantum foundations meeting in Erice (supported by COST) we celebrated the 80th birthday (somewhat in advance) of GianCarlo Ghirardi who famously worked on collapse models, in an attempt to deal with the quantum measurement...

Believe in Ghosts?
By ANTONY GARRETT LISI
Most of my research was motivated by an early frustration with what fermions are and where they come from, mathematically. A column of complex numbers, why? Ah, they're the irreducible spinor representation of the Lorentz group, or they're minimal...

The Fermi Paradox
By WILLIAM OREM
I'd be interested in hearing any proposed solutions to the Fermi Paradox. My experience has been that this is one of the Foundational Questions on which everyone you meet at a party has a ready answer, but the paradox turns out to be surprisingly...
