Yet, one can tease out the hidden

quantum gravity theory by carefully studying how information is encoded in the purely quantum-mechanical system.

The Express Tribune spoke to theoretical physicist Carlo Rovelli about his new book, the elusive nature of time, loop

quantum gravity and the human quest to understand the order of the cosmos.

The semiclassical equations for

quantum gravity are as from M0ller [3] and Rosenfeld [1]:

The connection between the spin-networks used in Loop

Quantum Gravity and the Ising model has recently been discussed in [18-20].

Quantum Gravity Roderick I.

It starts with Democritus, who lived and wrote 26 centuries ago, the man who gave us an "immense vision"--a world made of atoms--"on which the knowledge of a civilization would later be built." The journey continues with Lucretius, Galileo, Newton, Faraday and Einstein, of course, from classical physics to today's research on

quantum gravity. Rovelli's enthusiasm, his excitement about discovering the true nature of things, is enhanced by Roy McMillan's narration of this mind-expanding audio.

All three received the Prize for transformative advances in quantum field theory, string theory, and

quantum gravity.

Weatherall contends, for instance, that differing notions of nothingness between theories of general relativity and quantum mechanics could help explain why scientists are still struggling to unite the two ideas into one theory of

quantum gravity.

"The Philosophy of Physics" discusses the three pillars of modern physics (quantum mechanics, statistical mechanics, and the theories of relativity), in addition to more cutting-edge themes such as econophysics,

quantum gravity, quantum computers, and gauge theories.

The author, Carlo Rovelli, is a top research physicist who is a co-developer of the loop

quantum gravity theory.

A study about them has been published in journal Classical and

Quantum Gravity.
