An experiment designed to study neutrinos at the Gran Sasso Laboratories in Italy is under attack by populistic media. Why should you care? Because it's a glaring example of the challenges we face in the XXI century in our attempt to foster the progress of the human race.
What is a neutrino? Nothing - it's a particle as close to nothing as you can imagine. Almost massless, almost perfectly non-interacting, and yet incredibly mysterious and the key to the solution of many riddles in fundamental physics and cosmology. But it's really nothing you should worry about, or care about, if you want to lead your life oblivious of the intricacies of subnuclear physics. Which is fine of course - unless you try to use your ignorance to stop progress.
Following the appearance of Kent Staley's review
of my book "Anomaly!"
in the November 2017 issue of Physics Today, the online site of the magazine offers, starting today, an interview with yours truly
. I think the piece is quite readable and I encourage you to give it a look. Here I only quote a couple of passages for the laziest readers.
Another quite positive review of my book "Anomaly! Collider Physics and the Quest for New Phenomena at Fermilab"
(which these days is 40% off at the World Scientific site I am linking) has appeared on Physics Today
Writing a serious review of research in particle physics is a refreshing job - all the things that you already knew on that specific topic once sat on a fuzzy cloud somewhere in your brain, and now find their place in a tidily organized space, with clear interdependence among them. That's what I am experiencing as I progress with a 60-pageish thing on hadron collider searches for diboson resonances, which will appear sometime next year in a very high impact factor journal.
Today at CERN a workshop started on the physics of the High-Luminosity and High-Energy phases of Large Hadron Collider operations. This is a three-days event meant at preparing the ground for the decision on which, among several possible scenarios that have been pictured for the future of particle physics in Europe, will be the one on which the European Community will invest in the next few decades. The so-called "European Strategy for particle physics" will be decided in a couple of years, but getting the hard data on which to base that crucial decision is today's job.
Yesterday, October 20, was the international day of Statistics
. I took inspiration from it to select a clip from chapter 7 of my book "Anomaly! Collider physics and the quest for new phenomena at Fermilab"
which attempts to explain how physicists use the concept of statistical significance to give a quantitative meaning to their measurements of new effects. I hope you will enjoy it....
The Theory of Everything may be a mathematically simple model which is rich in implications and more difficult in concepts than calculations. The model I have just published as a candidate theory of everything is just such a model. String theory on the other hand is simple in concept but difficult in calculations. The concept of my model is that we treat all energy the same way. This is a MASSIVE oversimplification. All the scientific details for any experts that have questions are in the latest paper and the references to it.
Like many others, I listened to yesterday's (10/16/17) press release at the NSF without a special prior insight in the physics of neutron star mergers, or in the details of the measurements we can extract from the many observations that the detected event made possible. My knowledge of astrophysics is quite incomplete and piecemeal, so in some respects I could be considered a "layman" listening to a science outreach seminar.
Yet, of course, as a physicist I have a good basic understanding of the processes at the heart of the radiation emissions that took place two hundred million years ago in that faint, otherwise unconspicuous galaxy in Hydra.
At 10:00 AM this morning, my smartphone alerted me that in two months I will have to deliver a thorough review on the physics of boson pairs - a 50 page thing which does not yet even exist in the world of ideas. So I have better start planning carefully my time in the next 60 days, to find at least two clean weeks where I may cram in the required concentration. That will be the hard part!
Clamps are miniature
equivalents to the gravitational shock fronts caused by colliding black holes
that currently reach the press because very sensitive measuring equipment such
as LIGO can detect these fronts when they pass the
sensor. During travel, these fronts keep their shape, but the height
diminishes as 1/r as a function of the distance r to the trigger location. The
result is temporary, and the front integrates into the Green’s function of the
vibrating field. Thus, the spherical shock front deforms its carrier. Having
mass is synonym to having the capability to
deform its carrier. That vibrating field is our living space. Where a huge explosion triggers the front that passed
the LIGO sensor, are clamps triggered by a point-like artifact.
