The other day in class during an exploration into solid geometry, we discovered we could make these lovely flowers
by smashing the paper cones we had made.
Now, if I can just figure out how to test the students on this material.

It was superhero day at school, and a senior had donned some fake glasses as his costume. Confused, I inquired as to which superhero he was supposed to be. “Clark Kent,” he said. “Clark Kent is not a superhero,” I said. “Superman is a superhero, and Clark Kent is his alter ego.”
A rousing debate ensued. Well, it wasn’t really a debate; it was pretty much me against everyone else.
“No one calls out for Clark Kent in desperation,” I said. I was being difficult in my typical way. Yes, I was trying to make a legitimate philosophical point, but mostly I was just trying to intellectually irritate the students. The controlled chaos of classroom debate continued
“Bruce Wayne is not a superhero!” I was growing more confident in my stance, and sensed the argument drawing to a close. I was ready to claim victory. Then a clever student raised her hand. The class quieted.
“Clark Kent is Superman. Superman is a superhero. Therefore, by transitivity, Clark Kent is a superhero.”
In a rare moment, I had no clever response. In light of this stunningly elegant argument, I was forced to concede. But I’ll be back.
This photo reminds me of my favorite theorem from elementary geometry: if you connect the midpoints of two sides of a triangle, the segment is both parallel to, and half the length of, the third side.
