I officially get to do math for at least 3 more years!!!!!

Curled up white cat with orange spots on a green blanket

It is a good day and tomorrow I will be a cube!

problem set? i'm sorry but we do 21st century mathematics in this classroom. here's your problem category

There’s a past version of myself that would argue to the death that “Room on Fire” was a better album than “Is This It?” and I would now argue to the death with my past self that the opposite is true

UW HOMOTOPY MUG!!!!

math so hard guys wtf

I’m so broken by chromatic homotopy theory… I was just in a seminar about smooth structures on spheres (very real tangible stuff) and there was a brief connection with periodic elements in stable homotopy (very fake made up stuff) and the only questions I had were about vn-periodicity

an 8 cell diagram over the Steenrod algebra. Curved blue lines, angular purple lines connect some of the cells.

I have learned how to use tikz. I am unstoppable.

I personally count the number of times I read “bo-resolutions” this year as 50 books

Happy Holidays!! Last Christmas in Seattle. Maddy and I spent yesterday getting Japanese curry, reading, going out to see It’s a Wonderful Life (3rd year in a row!) and drinking homemade eggnog (not pictured bc drank it very fast)

Dust bunny guy and the wanderer are freaking awesome

Me and my girlfriend sitting at a table, 2 people having a discussion behind us.

Me and my girlfriend posing for a photograph. We are wearing 70s party attire: I have on a large collar light blue button up with a white sweater vest, Maddy has on a caramel tweed dress over a dark turtleneck. Both wearing black boots.

Group photo of my coworkers

Pictures from the Christmas party for the coffee shop I work at! My 2nd and 3rd year of grad school I worked regularly, and the last 2 years I have filled in here and there. Not a good idea to work a second job while getting a PhD, but it was certainly the most fun I’ve had in Seattle.

Just realized the song being quoted is hip to be square …

Bridge down

I love living next to a bridge

Two cats sharing a chair. Incredible

Both of them!

E1 page of a spectral sequence with entries depicted as planar loops

I need to up my spectral sequence game! These charts are awesome

I am begrudgingly thinking about equivariant classifying spaces

Cat in a silly adorable position on blanket

Just unbelievable

I should maybe clarify that I did enjoy that one… but his sentences never go anywhere! I get lost in his insane rambling and plot jumping

I think I’m just not capable of enjoying Thomas Pynchon no matter how hard I try

I have been in probably 5 hotel rooms this fall and I have caught only the second half of My Cousin Vinny at least 3 of those times. I still don’t know how that movie starts but geez that last scene with Marisa Tomei is so cool
