New Icons for Difficulty and Subject Area

New Icons!

You may have noticed that the blog has gotten more colorful! I have rolled out a set of icons that you can use to quickly identify the difficulty and content of each blog post.

####Difficulty Levels

Icon Difficulty Description
Easy Easy These posts cover introductory physics topics seen in an upper-level high school or lower-level college course. Depending on the post, you might see a few lines of basic calculus.
Medium Medium These posts cover intermediate physics topics that are usually seen by undergraduate physics majors. They include longer derivations and more sophisticated math techniques.
Hard Hard These posts cover advanced physics topics that are seen by upper-level undergraduate students and graduate students in physics. This is where I cover some of the difficult theory that physicists have to contend with.
