Chromodynamics: Gluons are just gonzo
One of the more fascinating bits of high-energy physics is the branch of physics called quantum chromodynamics (QCD). Don’t let the big name throw you off: it deals with a bunch of elementary particles that have a property called colour … Continue reading

Getting started on superconductivity
After the hoopla surrounding and attention on particle physics subsided, I realized that I’d been riding a speeding wagon all the time. All I’d done is used the lead-up to (the search for the Higgs boson) and the climax itself … Continue reading

Graphene the Ubiquitous
Every once in a while, a (revolutionary-in-hindsight) scientific discovery is made that’s at first treated as an anomaly, and then verified. Once established as a credible find, it goes through a period where it is subject to great curiosity and … Continue reading
