As a geometry teacher, I like to keep a Rubik’s Cube in my room. The students usually seem to think it’s a way for me to show off (my average time is about two minutes… not championship level, but fast enough to be impressive). But I’ve come to see the cube as a metaphor for…

Fuseli’s Favorite Fantasm
my friend is back sitting on my shoulder whispering in my ear telling me how pointless it all is how i’m talking to an empty room singing with a vacant orchestra shouting across the chasm at nobody when i turn to tell him to shut his mouth he disappears and i am at last…
Another Unarmed Black Man Murdered by Police…and This One Also Won’t be the Last
Here we go again. Every time I see the latest example of police brutality resulting in the death of an unarmed, usually black citizen, I try to be hopeful that this is the one that will cause the sleepers to wake up. Yet again, I’m disappointed. Terence Crutcher, 40, unarmed, black, and male, was shot…
The Vicious Cycle of Unequal Treatment
Critics of Black Lives Matter often argue that black Americans are more likely to commit crimes than white Americans, and that this explains why police are more likely to enter into an interaction with black suspects at a higher level of suspicion and aggression. Statistically, it’s true that African-Americans are disproportionately represented at all stages…
Inscribing an Equilateral Triangle
I was reminded of the cylindrical wedge that casts shadows of a triangle, a square, and a circle, and it got me wondering: What if I wanted to create such a shape with an equilateral triangle as one of its shadows? The wedge shown either casts an isosceles (but not equilateral) triangular shadow, or it…
The Evolution of Fear in Boys and Men
Lately, I’ve been thinking about the nature of fear. My son, age seven, has developed a consistent fear of marionettes and animatronics. The two monsters at the top of this anxiety are Mr. Slappy from the Goosebumps series and Foxy the Pirate from Five Nights at Freddy’s. The clarity of this fear reminds me of…
Shut Up and Dance
On August 26, 2016, a black man who is paid a lot of money to entertain people failed to stand for the National Anthem. In 2016 America, this is apparently news. This is the key part of the news. In the wake of this scandalous conduct, people have tried to make it about the man’s…
Cognitive Dissonance: Why Political Discussions Turn Nasty
If you’re like me, your social media has been populated lately with commentary using emotional appeals to get people to change their vote for President, with a combination of scare tactics to vote for Clinton or Trump in order to vote against the other and stubborn posts about the lesser of two evils still being…
Multiplying Negative Numbers
Students often struggle with the concept of multiplying negative numbers, particularly with the notion that multiplying two negative numbers results in a positive. I’ve seen numerous attempts by teachers and teacher educators to explain why, conceptually, it is that the product of two negative numbers is a positive number. However, what if the underlying presupposition…
Dismantling the Manhood Myth: Why It’s Damaging to Define Men in Terms of Size
When Donald Trump responded to Marco Rubio’s comment about his small hands being no indication of a problem elsewhere on his body, he invoked one of the most vulgar tropes about masculinity: That the size of the male genitals reflects an individual’s power. Like a pair of juvenile frat boys, Rubio and Trump quickly turned…
