Analyzing data from the Large Hadron Collider is challenging. Around 3,000 scientists work on the problem, which means that there are 3,000 people contributing software. With such a large group, it is paramount that the code be tested to ensure that a new contribution doesn’t cause the rest of the program to malfunction. Scientist Sam Hewamanage shows how the code is checked. View the video. Video: U.S. CMS

The Fermilab LHC Physics Center, or LPC, provides a hub for U.S. scientists. Rather than having to fly to Europe, where the LHC is located, scientists can instead visit Fermilab, where about 100 expert physicists reside. In this video, scientist Sam Hewamanage describes the LPC. View the video. Video: U.S. CMS

It might be obvious, but a crucial step in understanding our universe is to take physical properties, for instance energy and position, and to quantify them. Once the results have been quantified, we can then turn to powerful mathematical tools to better understand what is going on. Scientist Titas Roy helps us understand this better. View the video.

Quantum electrodynamics, or QED, describes the emission of light by charged particles. Typically this means light emitted by electrons, but any charged particles will do. In this video, scientist Titas Roy briefly talks about her studies of the light-emitting properties of top quarks. View the video. Video: U.S. CMS

Studying short-lived particles is a crucial ability for a particle physics experiment. In this video, scientist John Stupak describes how it is done. View the video. Video: U.S. CMS

Scientist John Stupak talks about the discovery of the Higgs boson. Did scientists find the Higgs boson predicted back in 1964 or did they find just one of a group of particles, with the others still to be found? View the video. Video: U.S. CMS

The term high-energy physics says it all. Measuring energy is a key capability for a modern particle physics experiment. In this video, Fermilab’s Don Lincoln explains how it’s done. View the video. Video: U.S. CMS

The kind of matter that makes up you and the chair you are sitting on is made of atoms. This form of matter makes up only 5 percent of the universe. The rest is composed of two other forms called dark matter and dark energy. Andrew Whitbeck tells of plans to try to make dark matter using the Large Hadron Collider. View the video. Video: US CMS

Fermilab’s Nhan Tran explains the challenges facing LHC scientists as they try to determine which collisions are important to record and which are ones we can ignore. View the video. Video: US CMS
