In this NOVA blog post by Don Lincoln, a senior experimental particle physicist at Fermi National Accelerator Laboratory and an adjunct professor at the University of Notre Dame, tries to shed some light on the the theoretical particles known as gravitons. He talks about what they are, and why it is so hard to find them, going briefly into a couple of new ideas that might help us to observe or detect these elusive particles if they exist.
The University of Edinburgh has paired up with FutureLearn to host the massive open online course (MOOC) called “The discovery of the Higgs boson“.
This MOOC introduces the theoretic tools needed to appreciate the discovery, and presents the elementary particles at the tiniest scales ever explored. Beginning with basic concepts in classical mechanics, the story unfolds through relativity and quantum mechanics, describing forces, matter and the unification of theories with an understanding driven by the tools of mathematics.
Narrating the journey through experimental results which led to the discovery in 2012, the course invites you to learn from a team of world-class physicists at Edinburgh University. Learners participate in discussion of the consequences of the Higgs boson, to physics and cosmology, and towards a stronger understanding and new description of the universe.
‘Colliding Particles’ is a series of films following just one of the teams of physicists involved in the research at the LHC. The project documents their work at the frontiers of particle physics, exploring the human stories behind the research and investigating the workings of the scientific process itself.
