Sir Roger Penrose: Cosmic Inflation Is ‘Fantasy'

(NPR Science Friday) Sir Roger Penrose calls string theory a "fashion," quantum mechanics "faith," and cosmic inflation a "fantasy." ... What's wrong with modern physics—and could alternative theories explain our observations of the universe? Full lectures: Fashion, Faith, and Fantasy in the New Physics of the Universe (Lecture 1: FASHION)(Lecture 2: FAITH.)(Lecture 3: FANTASY.) [more inside]

My God, it's full of... everything

Revelations in the field of quantum physics have resulted in the discovery of the Amplituhedron, a jewel-like higher dimensional object whose volume elegantly predicts fundamental physical processes that took the brilliant Dr. Richard Feynman hundreds of pages of abstruse mathematics to describe. The theoretical manifold not only enables simple pen-and-paper calculation of physics that would normally require supercomputers to work out, but also challenges basic assumptions about the nature of reality -- forgoing the core concepts of locality and unitarity and suggesting that space and time are merely emergent properties of a timeless, infinitely-sided "master amplituhedron," whose geometry represents the sum total of all physical interactions.

“You’re maybe going to take this journey with me for a spell, People aren’t stones.”

"... That’s the way with epiphanies: You can’t know in advance what they’ll be. Even me. I can see them coming, but I can’t understand something until I understand it.”

Get ready for ?

We’re on the verge of two world-changing antimatter discoveries While the Large Hadron Collider is looking for the Higgs boson, we're on the verge of two huge antimatter-related breakthroughs. One could finally solve the universe's oldest mystery, while the other could reveal strange new particles that are perfect for quantum computers.

Schrödinger's Ratio

If you look around, you'll see that the ratio of 1.618:1 appears in architecture, nature, and artistic works (such as music, previously). Studied by the Greeks, the Golden Ratio is pretty much everywhere and is common accepted as aesthetically pleasing, and now it has been found to exist down into the nanoscale level, as a byproduct of investigating the Heisenberg Uncertainty Principle. We may not be able to nail down both position and speed, but it appears the macro ratio is an echo of the micro one. [more inside]

Quantum Chess!

"Computers can search all possible outcomes of all possible moves in conventional chess and beat even top human players, so Akl wanted to make the computation more difficult." The result? Quantum chess! [via]

The Blegdamsvej Faust

The year is 1932. Hitler is rising in power. Harold Urey announces the discovery of deuterium, a hydrogen isotope. James Chadwick discovers the neutron. Heisenberg receives the Nobel Prize for his work in Quantum physics. It is a miracle year in Physics, matched only by Einstein's advances in 1905. A few of the most brilliant physicists in the world decide to convene in Copenhagen and ... write a play! Written on the 100th anniversary of the death of Goethe, The Blegdamsvej Faust is a remarkable document from a turning point in Physics. [more inside]

Psi Not?

"You bend your words like Uri Geller's spoons", sang Toad. But how is it that science can dismiss Geller as the fraud he is without experimenting on every psychic claimant? Surely someone claiming telekinetic powers might be telling the truth? Quantum physics to the rescue.
