More Is Difficult

I’ve remarked several times that I think condensed matter physics gets slighted in public discussions of the field, especially relative to its usefulness. Particle physics gets all sorts of press, but in practical terms, it is essentially useless– whether CERN or Fermilab locate the Higgs boson or not will make absolutely no difference in the… Continue reading More Is Difficult

Matter and Interactions and Dark Matter for Kids

New ScienceBlogger and American Gladiator Ethan Siegel of Starts With a Bang has a couple of nice posts about dark matter and how we know it’s there (one, two). These posts reminded me that I never did follow up on the discussion following my post about Magic World Media, who are looking to publish kids’… Continue reading Matter and Interactions and Dark Matter for Kids

The Process Is as Important as the Answer

Over at the First Excited State, the quasi-anonymous proprietor laments the tendency of basketball replays to focus on the shot rather than the play that set up the shot, and compares this to a maddening student habit: Students in introductory physics classes inevitably place too much focus on the final numerical answer of the problem,… Continue reading The Process Is as Important as the Answer

Physics Communication Strategies

Physics World this month has a nice article by Robert Crease on the strategies used in popular physics books, drawing on a study of popular books by Elizabeth Leane (Reading Popular Physics, much of which is available via Google Books). He talks about three different strategies that she identifies, and how they’re employed in different… Continue reading Physics Communication Strategies

Up for Adoption

The spring round of the Adopt-a-Physicist outreach program will begin soon. I did this in the Fall, and it was a good experience, so I’ve registered myself again. The program pairs volunteer physicists with high school classes, and provides a web forum in which students can ask questions about physics and careers in physics. Back… Continue reading Up for Adoption

Course Report: Nuclei and Particles in 3+1 Classes

This is the final report on my modern physics class from last term, covering the last week of classes, which generally deal with nuclear and particle physics. This was actually three-and-a-bit classes, because I lost one class to a nasty cold a few weeks earlier, and used part of the lab period to make up… Continue reading Course Report: Nuclei and Particles in 3+1 Classes

Course Report: Solid State Physics in Three Classes

In the last course report post, we dispensed of atomic and molecular physics in just three classes. The next three classes do the same for solid state physics. Class 25 picks up on the idea of basic molecular potentials from the end of the previous class, and uses that to introduce energy bands in a… Continue reading Course Report: Solid State Physics in Three Classes

Course Report: Atoms and Molecules in Three Classes

I got way behind on my reports from my Modern Physics class– the last one was over month ago, and the class has since ended. There’s enough material left to be really awkward as a single post, though, so I’m going to take my cue from Brandon Sanderson and split it into three parts. The… Continue reading Course Report: Atoms and Molecules in Three Classes
