Overheard: prograde/retrograde/diurnal planetary motion
Astronomy 210, Spring Semester 2011
Cuesta College, San Luis Obispo, CA
(Overheard after a whole-class discussion following an in-class activity ("lecture-tutorial") on the relative motions of prograde/retrograde motions of planets with respect to the background stars, and motions of planets across the celestial sphere in a single night.)
Student (realizing that prograde/retrograde motion of planets is much slower than their diurnal motion over a single night after instructor's class-wide explanation): "I don't know if it's because I'm a genius or if you're just a good explainer, but I totally get it now."
(Beat.)
Instructor: "I'm willing to split the difference."
Student: "Fair enough."

Overheard: Febtober
Astronomy 210L, Spring Semester 2011
Cuesta College, San Luis Obispo, CA
(Overheard during a backwards faded scaffolding introductory astronomy laboratory on the motions of the sun on January 31, 2011.)
Student 1: "Could you take a look at our computer? It [the Heavens-above.com Astronomy > Whole sky chart webpage] is giving us error messages."
Instructor: "What's going on?"
Student 2: "If we put in today's date, we get the star map to load. [Inputs 01 31 2011; star map loads.] If we put in two months from now, we also get that star map to load. [Inputs 03 31 2011; star map loads.] But when we go back to just one month from now, we get an error message. [Inputs 02 31 2011; error message comes up.]"
Instructor: "There's your problem right there."
(Beat.)
Instructor: "How many days does February have?"
(Beat.)
Student 1: "What?"
(Beat.)
Student 2: "Oh."
Esprit d'escalier:
Instructor (using best Sean Connery voice): "Since next month has 31 days, it must be...Febtober."
Student 2: "Then would Jantember be when this month has only 30 days?"
