Ultimate Guide to the Multiverse
Whether we are searching the cosmos or probing the subatomic realm, our most successful theories lead to the inescapable conclusion that our universe is just a speck in a vast sea of universes.

Quantum Theorem Shakes Foundations
At the heart of the weirdness for which the field of quantum mechanics is famous is the wavefunction, a powerful but mysterious entity that is used to determine the probabilities that quantum particles will have certain properties. Now, a preprint posted online reopens the question of what the wavefunction represents—with an answer that could rock…

Proof Found for Unifying Quantum Principle
When John Cardy proposed a far-reaching principle to constrain all possible theories of quantum particles and fields, he expected it to be quickly rebutted. But for almost 25 years that hasn’t happened—and it now seems that his theorem may have been quietly proved earlier this year. If the solution holds, it is likely to guide…

The Quantum Universe
Brian Cox’s latest book, The Quantum Universe, which he co-wrote with Jeff Forshaw of the University of Manchester, is not a dry undergraduate text book, but nor is it a particularly easy read. The subject matter is hard. Quantum mechanics, which describes in subatomic detail a shadowy world in which cats can be simultaneously alive…

Cosmic Optimism: From the Principle of Maximum Diversity to Path Optimization
Before we turn to the Principle of Maximum Diversity, we review the development of the Principle of Least Action (or Effort), one of the mainstays of modern physics.

From Certainty to Uncertainty, Pt. 1
Quantum theory forces us to see the limits of our abilities to make images, to create metaphors, and push language to its ends. As we struggle to gaze into the limits of nature we dimly begin to discern something hidden in the dark shadows.

Taking a Look at Evolution From Quantum Reality
Molecules are the basis of life and molecules are quantum systems. We must, therefore, enter our knowledge of the quantum structure of molecules into the discussion of biology.

Of Quantum Non-Locality & Anti-Bullets
Responding to the question: What is the relation between quantum theory and religion or religious experience?

The Quantum Wave Function as a Psychological Barrier
Despite its formidable achievements, there is no consensus what quantum theory tells us about Nature.

Wolfgang Pauli: Resurrection of Spirit in the World
In considering this relationship between science and religion it is useful to turn to the life of Wolfgang Pauli, one of the most important physicists of the twentieth century.
