Fibonacci: Hmm... I sure wish there was a way to mathematically represent an empty quantity.

The simple yet useful Arabic numeral:

log (😅) = 💧log 😄

One of my professors told us that as a teacher, you WILL cause harm at some point in your career. You will say something hurtful to a student or grade unfairly or make a harmful assumption. You learn about these things and try to avoid them, but if you teach long enough you will do something that’s harmful to a student. It’s a numbers game. It’s inevitable.

And that’s why it’s important that you learn how to react in a healthy and productive way! The example she gave was from her own teaching — she had an assignment where students made a presentation with photos that showed their relationship with math over their life (I studied math education). A trans student reached out and told her that they were uncomfortable using pretransition photos. In response, she changed the assignment! By the time I was in her class, it was “make a presentation with photos and/or memes” — a small change but definitely more inclusive!

I think this illustrates why it’s important to say something when you experience microaggressions. I, a trans person taking this class, had a more positive experience because a different trans person spoke up a couple years before.

But also, I think that harm is inevitable outside of teaching too. I think that if you have friends or family or interact with people regularly, you WILL hurt someone eventually. And you have to be comfortable with that possibility in order to respond in a healthy way.

I close my eyes. I enter my Mathemagical Mind Palace. I see the object before me. I'm working out the differential equations. The derivative of the function with respect to time is equal to a constant times the second derivative of the function with respect to distance from the origin. A billion vectors rendered in with ray-tracing. I see the phase portrait. I see the three-dimensional manifold in a four-dimensional space. The shadows on the wall and the ancient beings who make the shadows. I peer into the amethyst eyes of the unyielding serpent. I have done my calculation.

Out of the suggested cooking time of "18 to 20 minutes", I will be cooking this pizza for: 19 minutes.

if a number divided by itself is always equal to 1, surely this holds true for 0/0 as well
