What can be really said about the physical origin and the ultimate nature of the properties of matter described by Quantum Mechanics?

  Besides the inevitable emotional doubts accompanying fundamental physics research, Einstein’s results (in the EPR article) are right - there is action at a distance

The first really exciting thing from Run 2 at the CERN Large Hadron Collider (at least for me) has finally appeared. A 2.9 TeV dielectron event was recorded by CMS on August 22. At this mass a new Z' boson is not excluded by Run 1 searches.... And in the whole Run 1 data the highest-mass dielectron event collected by CMS was only 1.8 TeV. So by raising the centre-of-mass energy by 60% we collect a 60%-higher-mass event, but with 0.5% of the collisions. It is nice to think that the event might really be the first hint of a new resonance !

Back around 1960, at school I enjoyed a laboratory lecture on liquid nitrogen, watching a deep frozen squash ball being shattered at a temperature well below that at which it turns from a rubber into a glass, and then seeing a nail being driven into a block of wood with a hammer whose head was made of frozen mercury.  The repeated impacts left an impression of the nail head in the soft metal.

What is a quaternion? Mathematicians might claim it was the independent inventions of Gauss, Hamilton, and Rodrigues. Unit quaternions are useful to do 3D rotations and as an esteemed member of the standard model. They are also one of many Clifford algebras, Cl(0, 2) being its formal name.

Stephen Hawking said something! And again the international media is all a'buzz.
The fourth edition of the International Conference on New Frontiers in Physics has ended yesterday evening, and it is time for a summary. However, this year I must say that I am not in a good position to give an overview of the most interesting physics discussion that have taken place here, as I was involved in the organization of events for the conference and I could only attend a relatively small fraction of the presentations.
ICNFP offers a broad view on the forefront topics of many areas of physics, with the main topics being nuclear and particle physics, yet with astrophysics and theoretical developments in quantum mechanics and related subjects also playing a major role. 
As a whistle-blower and interdisciplinary scientist who appreciates the strength of philosophical arguments (read: logic!), I receive idiotic rejections declining to publish my work, perusing laughably silly justifications all the time. This is understandable in today’s throughout PC, eggshell walking careerist academia and publish-or-perish corrupted scientific community. But there are different degrees of how sure-of-themselves proud the rejections are for example. Physicists usually at least pretend to argue something, no matter it is clear that the editor or reviewers have not read beyond the abstract and reference list in order to find out whether they were cited.


One of the important things in life is to have a job you enjoy and which is a motivation for waking up in the morning. I can say I am lucky enough to be in that situation. Besides providing me with endless entertainment through the large dataset I enjoy analyzing, and the constant challenge to find new ways and ideas to extract more information from data, my job also gives me the opportunity to gamble - and win money, occasionally.
Nowadays Physics is a very big chunck of science, and although in our University courses we try to give our students a basic knowledge of all of it, it has become increasingly clear that it is very hard to keep up to date with the developments in such diverse sub-fields as quantum optics, material science, particle physics, astrophysics, quantum field theory, statistical physics, thermodynamics, etcetera.

Simply put, there is not enough time within the average life time of a human being to read and learn about everything that is being studied in dozens of different disciplines that form what one may generically call "Physics.
