I’m currently at the Quark Matter 2012 conference in Washington, DC, wearing my reporter hat for Ars Technica. Quark Matter is the international conference covering results in ultrarelavistic (meaning: extremely close to the speed of light) collisions between nuclei. We’ll be hearing from a number of the most important experiments in that area: the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory, the Large Hadron Collider (LHC) at CERN, and others. I’ll be live-tweeting the plenary sessions under the hashtag #QuarkMatter, if you want to follow along (no Twitter account necessary!).
