Explore high energy physics at the Large Hadron Collider (LHC) in this Friday Evening Discourse at the Royal Institution. Join Professor Jon Butterworth, a member of the High Energy Physics group on the Atlas experiment, as he provides an in-depth overview of his work at the LHC. Delve into topics such as the Standard Model, Atlas Detector, muons, collisions, and the energy frontier. Gain insights into short wavelengths, energy density, conservation, and virtual particles. Understand the significance of data analysis in particle physics and learn about the everyday universe, the Higgs boson, and B quarks. This lecture continues the prestigious tradition of Friday Evening Discourses at the Royal Institution, which has featured major scientific figures since 1825.
