Here's a funny little variation on "rickrolling," a term some of our readers might not be familiar with. So let's quickly refer you to Wikipedia:
Rickrolling is an Internet meme involving the music video for the 1987 Rick Astley song "Never Gonna Give You Up". The meme is a bait and switch; a person provides a hyperlink which is seemingly relevant to the topic at hand, but actually leads to Astley's video. The link can be masked or obfuscated in some manner so that the user cannot determine the true destination of the link without clicking. People led to the music video are said to have been rickrolled. Rickrolling has extended beyond web links to playing the video or song disruptively in other situations, including public places, such as a live appearance of Astley himself in the 2008 Macy's Thanksgiving Day Parade in New York. The meme helped to revive Astley's career.
Now, in another sign that rickrolling has gone beyond the web, we have above a snapshot of a quantum physics written by Sairam Gudiseva, a student at (we believe) White Station High School in Tennessee. As the snapshot shows, Gudiseva managed to run the lyrics of "Never Gonna Give You Up" down the left margin of the page ... while still keeping his ideas flowing. Well done, young man. You can see a full page of his essay here.
By the way, this is not the first time some levity has been introduced to a physic paper. You might want to refer back to our 2012 post, Physical Attraction: Marriage Proposal Comes in the Form of a Physics Paper.
