Why Time Might Not Be an Illusion
Einstein’s relativity pushes physicists towards a picture of the universe as a block, in which the past, present, and future all exist on the same footing; but maybe that shift in thinking has gone too far.

The Complexity Conundrum
Resolving the black hole firewall paradox—by calculating what a real astronaut would compute at the black hole's edge.

Quantum Dream Time
Defining a ‘quantum clock’ and a 'quantum ruler' could help those attempting to unify physics—and solve the mystery of vanishing time.

Our Place in the Multiverse
Calculating the odds that intelligent observers arise in parallel universes—and working out what they might see.

Sounding the Drums to Listen for Gravity’s Effect on Quantum Phenomena
A bench-top experiment could test the notion that gravity breaks delicate quantum superpositions.

Quantum Reality Check
Photon experiments suggest the wavefunction is real -- and quantum cats truly are dead and alive at the same time -- as physicists Alessandro Fedrizzi and Martin Ringbauer explain. Plus, FQXi releases its first two books.

Detecting Black Hole Firewalls
If you fell into a black hole would you be stretched into spaghetti or would you catch fire? Cosmologist Niayesh Afshordi discusses the possibility that neutrinos detected on Earth hold the answer. They may have been created by a ring of fire surrounding back holes.

Both of these publications are very good and interesting for the students, and people who are searching for some knowledge about the Information technology. People are discussing it at and some other places as well. Thanks a lot for sharing such information with others to make them interested in it, and get these books some more readers.
