Jen-Luc Piquant and the Time Lord are off for a physics workshop in Trieste, followed by some vacation time in Buenos Aires, so the weekly roundups will be on hiatus for a couple of weeks. We'll be back July 29, though, and in the meantime, there was plenty of juicy physics news this past week to tide you over.
Tuesday was Independence Day, so everyone dusted off their evergreen explainers for the occasion to tell you everything you need to know about the explosive science of fireworks. Like, These are the Minerals That Give Fireworks Their Colors. Glitter starch, and gunpowder: Those are the chemicals that make fireworks burn, blast off, and change colors. Related: You’re A Firework (Scientifically Speaking): "The same process that powers those explosions is going on inside a grill when you cook a hot dog, and inside your body when you eat that hot dog.” Also: A recipe for disaster? Medieval fireworks: "Their use in England was first recorded in 1486 at the wedding of King Henry VII." Bonus: While most of us enjoy fireworks at night, there are special formulations made for daylight use. Finally, What were the 'rockets red glare' in the "Star Spangled Banner"?
July 4 was also the five-year anniversary of the announcement at CERN that physicists had discovered the Higgs boson. When physicists first switched on the particle collider, the world worried about black holes. But they ran into a totally different kind of problem. Related: When was the Higgs actually discovered? The announcement on July 4 was just one part of the story. Take a peek behind the scenes of the discovery of the Higgs boson.
Speaking of the CERN and the LHC, physicists discovered a particle with a double dose of charm. The new double heavy particle is expected to shine light on the strong force. Related: New Particle Discovery Reignites Decade-Old Physics Controversy.
