"Happy Monday, everyone!" The professor paces at the front of the room. "Last week's problem set is all graded and your results are in the student portal. We're going to start on our next unit today. But just to give you all a little more time to wake up, I thought I'd go over some of the answers - and share a few particularly clever solutions..."
He pulls up a powerpoint slide.
"Emily Azuma - problem 9. Extremely thorough and done in a way I haven't seen before."
"And today I have another name to call out besides the usual... Nicholas Smith - problem 6. By using polar coordinates instead of Cartesian, the problem actually becomes a lot easier!"
Nick stands up, smug, and does a dramatic bow with a flourish when his name is called, triggering a wave of amused noise in the classroom.
"Yes, yes, good work. A new name breaking onto my little stage. Settle down, we have a lot to go over, as usual."
And class starts.
