The title text is referring to {{w|Phil Plait}}'s claim about the size of the sky, which was published on his blog: http://www.badastronomy.com/bitesize/bigsky.html. Dimensional analysis utilizes the rationale that both sides of an equation need to have the same unit. Radius typically refers to a length, which has SI units of meters. The surface area has SI units of square meters. The units of Phil Plait's "angular area" is as the title text mentions, {{w|square degrees}}. Thus the comic's {{w|dimensional analysis|dimensional analysts}} (not a profession, but instead the adherents of the mathematical technique) are said to be angered by this argument. | The title text is referring to {{w|Phil Plait}}'s claim about the size of the sky, which was published on his blog: http://www.badastronomy.com/bitesize/bigsky.html.
