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 !
Images of the systematic destruction of archaeological sites and art pieces in Syria are no news any more, but I was especially saddened to see before/after aerial pictures of Palmyra's site today, which demonstrate how the beautiful temple of Bel has been completely destroyed by explosives. A picture of the temple is shown below.

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. 
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. 


Twenty years have passed since the first observation of the top quark, the last of the collection of six that constitutes the matter of which atomic nuclei are made. And in these twenty years particle physics has made some quite serious leaps forward; the discovery that neutrinos oscillate and have mass (albeit a tiny one), and the discovery of the Higgs boson are the two most important ones to cite. Yet the top quark remains a very interesting object to study at particle colliders.
