May 16, 2012 — Once again quantum physics gives us philosophical implications: physicists showed how a small amount of randomness can be amplified without limit. Classical physics is deterministic: for example, we can determine the position and velocity of a particle at any time in the future. Quantum theory, on the other hand, states that there exist processes which are fundamentally random: for instance, the outcomes of measurements of quantum particles seem to be determined entirely by chance. This is why Einstein argued in a publication in 1935 that the quantum theory is incomplete, and yet another kind of higher theory must exist, but up to the present time there has been no proof either that the world is purely deterministic and all randomness is due solely to a lack of knowledge about certain events, or that everything happens purely by chance. However, ETH Zurich physicists have now succeeded in showing in a thought experiment that randomness can be amplified.
A Theory on the Deja Vu or Déjà vu Phenomenon During the time while this web-page has been on the Internet, more than three thousand people (up to Nov 2009) have e-mailed to say that they have Déjà Vu experiences.
Course Overview Welcome to Physics for the 21st Century : an on-line course that explores the frontiers of physics. The 11 units, accompanied by videos, interactive simulations, and a comprehensive Facilitator's Guide, work together to present an overview of key areas of rapidly-advancing knowledge in the field, arranged from the sub-atomic scale to the cosmological. The goal is to make the frontiers of physics accessible to anyone with an inquisitive mind who wants to experience the excitement, probe the mystery, and understand the human aspects of modern physics.

Posted by majestic on July 4, 2012 CERN has indicated that after many false starts, it has finally found proof of the elusive “God Particle,” a/k/a the Higgs boson. It’s widely being hailed as the most significant scientific discovery of our generation, etc. But what exactly is it?
By William J. Cromie Gazette Staff "Two years ago we slowed it down to 38 miles an hour; now we've been able to park it then bring it back up to full speed."
John Gribbin For seventy years, physicists have worried about what quantum mechanics means.
We’ve been discussing the Higgs (its interactions , its role in particle mass , and its vacuum expectation value ) as part of our ongoing series on understanding the Standard Model with Feynman diagrams .

Quantum mechanics is an area of physics dealing with phenomena where the action is on the order of the Planck constant .

That's an easy one: it's the science of things so small that the quantum nature of reality has an effect.
“I found I could say things with color and shapes that I couldn’t say any other way — things I had no words for.” - When it comes to the Universe, it isn’t just the stuff that’s in it that’s important.
