I like fantasy video games.
The end you finally done it you’ve proven that the series converge is to pi squared over six you’ve published your work in a prestigious journal. you’ve been asked to your work mathematics conferences, your professor approaches you and i’m proud of you. I always knew you could do it. This problem has been unsolved for centuries. None of my other students could even touch it, but you not only approved that the serious conversion you found what it converses with a very elegant proof as the faculty position open in our university, are you interestedyou accept the offer and get to work as a professor the end.

Old Long Beach, as portrayed in the lobby of my building.
Black and white Photo taken from high and out in the ocean of downtown. There’s a semi-circular road that I’ve heard is called Rainbow Road. Photo of pier and beach, including roller coasters. Folks on beach are in wool suits and long dresses. The beach is absolutely packed with beach umbrellas. Photo of surfers and a recognizable hotel. From the top it would look like a square with a quarter circle removed centered at a corner. Looks a bit like a Bavarian tower. Arial photo of the busy beach and some downtown buildings, including the hotel from the previous photo.

Pink rock that looks like a giant Himalayan salt block. Surrounded by a fence because reasons.

This is on the wall outside my office door.
A representation of Pascal/Yang Hui’s Triangle. The center of the bottom row read … 120, 210, 252, 120, 120…

A guide to deciphering dessert. It contrasts cobbler, crumble, pandowdy, grunt, pie, crisp, buckle, and Betty based on how it’s cooked how the starch wraps and what materials the starch or pastries are made of. sorry the image is too small for me to read the text to turn it into all text

Eddy is a leather daddy!?

(I’d already paid for Duolingo for the year when they announced evil.)
Duolingo story about Eddy and Junior. Junior wants to be like hi dad, who he thinks is a lion tamer because he has whips and leather pants in his wardrobe.

No interest in marriage, but:

I do not know why I am so amused by this EMAIL that I received from a real website that I have previously given money.
What's your pet's sight? Gray cat looking up to the side, surrounded by the icons for the 12 Zodiac signs in a circle around its head.

Big day con el búho!
An announcement that I am on a 365 day learning streak with Duolingo featuring an owl that is on fire like a phoenix with glowing kind of creepy eyes. A notification from Duolingo that I have reached Spanish level 45 and then I have increased my Spanish score. It features an owl in this superhero pose, kneeling on a floating desk, glaring at us as though it’s about to leap into action.

Meet was a bit of a euphemism.
Mickey cat standing on my shoulders with her butt on the side of my head. I am laughing and her tail is knocking my hair into my face.

Boom!
This course has also radically shifted the way I view mathematics. At the beginning of the semester I thought of mathematics as extremely rigid and inaccessible. Something that can only be done by highly educated experts. As students and non-experts we would only learn from those experts and use what they create. Now I see it as much more similar to music, something that everyone can explore and participate in.
