Note to readers: this is my best attempt to describe some issues in accelerator operations; I welcome comments from people more expert than me if you think I don’t have things quite right. The operators of the Large Hadron Collider seek to collide as many protons as possible. The experimenters who study these collisions seek [...]

I’ve been away from blogging for quite some time – mainly to finish a book I was working on.   The book is unrelated to particle physics, but follows a course I teach at Harvard, called Primitive Navigation.   We explore navigational techniques used by cultures like the Polynesians and Norse, in addition to looking at environmental [...]

Okay, so there hasn’t been an official IceCube press release on this, not until the paper finishes collaboration review and is posted on the Arxiv, but there have been some talks showing neutrino events observed by IceCube which are almost certainly astrophysical in origin. Short version, neutrino astronomy is now a real thing. We are [...]

This essay makes a point that is only implicit in most of my other essays–namely that scientists are arro—oops that is for another post. The point here is that science is defined not by how it goes about acquiring knowledge but rather by how it defines knowledge. The underlying claim is that the definitions of [...]

A l’occasion de l’ouverture de l’appel à candidature 2013 de “Sciences à l’Ecole” pour l’accueil d’enseignants français au CERN durant une semaine, nous publions ces jours-ci le journal quotidien plein d’humour de Jocelyn Etienne qui a suivi ce programme l’année dernière, au mois de novembre dernier.   Chambre à brouillard: la chasse aux particules commence [...]

This Fermilab press release came out on May 8. Read the original press release. Scientists from 26 institutions around the world are planning a new experiment that could open the doors to new realms of particle physics. But first, they have to bring the core of this experiment, a complex electromagnet that spans 50 feet [...]

The US high-energy physics community is planning the next two or three decades of its future. The process, called Snowmass, is a big deal for everyone interested in astro/particle physics, cosmology and related areas. That is especially important in these times of shrinking budgets and dire job prospects, which affect academic career paths of researchers [...]

This article originally appeared in Fermilab Today on April 26, 2013. The Dark Energy Survey (DES) collaboration has captured images of 176 star explosions, called supernovae, including 16 that occurred farther than 7 billion light-years away and when the universe was only about half as old as it is today. A new type of CCD [...]

I wanted to bring to everyone’s attention a really great opportunity that is happening tomorrow. The Intensity Frontier Workshop at Argonne National Labs is taking place this Thursday (4/25/13) and Friday (4/26/13) and Snowmass Young has been given an entire parallel session during this important pre-Snowmass meeting. We have had three speakers agree to come [...]

This article originally appeared in symmetry on April 16, 2013. Suppose a team of auditors is tasked with understanding a particular billionaire’s bank account. Each month, millions of dollars flow into and out of the account. If the auditors look at the account on random days, they see varying amounts of money. However, on the [...]
