ATLAS is one of the largest and most complex science instruments ever built, designed to measure and identify particles coming from particle collisions. One of the most important measurements it makes is that of the energy of the particles. Stephen Goldfarb, ATLAS physicist (U of Michigan, USA) interviews ATLAS colleague Isabelle Wingerter-Seez, the Liquid Argon Calorimeter system project leader to find out how these measurements are made.

The ATLAS detector on the LHC will give us more and more data on particle collisions than has ever before been collected. How do ATLAS scientists select and keep the data that is important to them? In this interview by ATLAS's Steven Goldfarb (U Michigan), Wengler describes in simple terms what the trigger system is and how it works.

In ATLAS, the very first component that is reached by colliding particles is the inner detector. As particles collide, their tracks, momentum and charge must be measured with the highest degree of precision. In this interview by ATLAS physicist Steven Goldfarb of colleague Pippa Wells, ATLAS Inner Detector System Project Leader, viewers learn how this measurement is done in the heart of ATLAS.

The ATLAS detector is built with several layers designed to study different types of particles. At the outer-most layer lies the Muon spectrometer. ATLAS physicist Steven Goldfarb (U of Michigan, USA) interviews Ludovico Pontecorvo, ATLAS Muon System Project Leader to find out how the Muon Spectrometer measures these very small particles precisely.

ATLAS physicist Steven Goldfarb interviews colleague Fabiola Gianotti, ATLAS spokesperson. In this interview, Gianotti describes in simple terms the complexity of ATLAS construction and what it is designed to do. Topics covered include the numbers in the ATLAS collaboration, detector dimensions, numbers of electronic channels and length of cables, the readiness of the experiment for high energy collisions, possible discoveries, hunting the Higgs and how it will take time, and the potential benefits of findings to human kind.

Fermilab scientist Don Lincoln describes antimatter and its properties. He also explains why antimatter, though a reality, doesn't pose any current threat to our existence!

This is the worldwide first model of coupled pendula, which demonstrates the complete phenomenology of neutrino flavor-oscillations for 3 different neutrino species (flavors). Up until now, only models for just 2 flavors existed. The model is adjustable corresponding to variable neutrino mass differences and variable mixing parameters (PMNS angles) between the 3 flavors. Arbitrary oscillation patterns like those for solar neutrinos or atmospheric neutrinos can be simulated with any parameter settings (e.g. with the mixing angle 1-3 being zero or non-zero).

The Quarked! project was conceived by Professor Alice Bean and a diverse team of collaborators at the University of Kansas in 2003 as an entertaining method of introducing the world of subatomic physics to kids and adults. (...) Now, Quarked! - Adventures in the Subatomic Universe brings subatomic physics to life through a multimedia project including an interactive website, a facilitated program for museums and schools, and an educational outreach program. (...) Targeted to kids ages 7-12 (and their families), the Quarked!

Nel 2016 viene annunciata la scoperta delle onde gravitazionali. Un anno dopo, i fisici registrano il primo segnale “multimessaggero” della storia della scienza, aprendo la strada ad una nuova branca della fisica: l’astronomia multimessaggera.
