From Prof. Chad Orzel's Graduation Speech: Science isn't a body of facts, science is a process for figuring out how the world works: you see something interesting, come up with an idea of why that…

If you have followed this blog for long enough, dear readers, the words "multi-muons", "anomalous muons", or even "lepton jets" are not foreign to you. They all refer to a paper appeared on the ArXiv…

In a few days italian post-docs working in high-energy physics will be asked to gather for a nasty exam, held by the INFN -the italian institute for nuclear physics- to qualify valiant researchers…

PrologueSome of you might remember the ripples caused in the blogosphere by the two-standard-deviation excess found by the CDF collaboration in their data in January 2007, while searching for a Higgs…

Below I offer a preview of the slides I will show tomorrow at an invited seminar on the rather technical topic of  "The b-jet energy calibration with Z-->bb decays", which I have come to CERN…

Tomorrow I am traveling to CERN, where I have been invited to give a seminar at a meeting of the LHCb experiment. My talk will discuss the issue of the energy calibration of b-quark jets, a topic to…

Created in a Bose Einstein Condensate, sound may enter these acoustic black holes but it may not leave.  This creates an system we can experiment with on a table top level and learn about black…

    Early science decided on the topology of matter as a system of atoms, durable units of mass.   The development of the full periodic table of elements gave each one a…

The search for planets capable of sustainable life (as we know it) is on, but with an infinite number of planets astronomers are focusing their attention on each system's 'habitable zone', where heat…

It is a well-known fact that it is much easier to measure a physical quantity than to correctly assess the magnitude of the uncertainty on the measurement: the uncertainty is everything! A trivial…
