Approximately 7 months ago, during my spectral theory class, I learned of the word sesquilinear and haven't gotten over it since.

Sesquilinear is the property of being linear in one argument and being conjugate linear in the other. In contrast to being bilinear, i.e. linear in both arguments. The root "sesqui" means one and a half, which, tbf, is reasonable enough.

(Side note: this is a property of inner products, which I learned about years ago? But I don't recall my previous measure/functional prof ever using it? Idk maybe just a language thing.)

But I think the word is just so funny? It sounds *silly*.

My perspective has only been moved into sillier territory by one of my friends adding "sesquilinear" to the "potential leopard gecko names" list that's taped to our office wall, shortly after we covered inner products in one of our shared classes this semester.

Idk when he added it, but he was there when I first noticed so I commented it seemed rather mean to do that. Then I recalled that he didn't actually like leopard geckos so okay, makes more sense now. Still mean, but makes sense.

Consequently, if I'm tired or otherwise a little out of it and hear sesquilinear, I cannot handle it and will have to stiffle giggles.

This hit recently during my linear algebra class when we defined bilinear, which shouldn't really have set it off since 1) literally not the same word 2) I wasn't even that tired. A little bored if anything. Otoh, same prof for spectral and linear. So I just sat and continued taking notes while grinning and smothering my giggles. Unknown if the professor noticed.

Parent Functions

I'm taking functional analysis and baby mathematician's first PDEs course (by which I of course mean it's a qual course) and since PDEs is actually just secretly functional, my constant state of being is calculating norms and inner products.

One of my friends who's also taking PDEs walked in to me doing functional homework and sounded sad on my behalf about the amount of norms I've been dealing with.

The analysis qual sequence (not measure and functional) also recently introduced norms, but like. Lightly.

update will be up tomorrow sometime!

also if u sent me an ask or message recently i promise i see it i’ll get to y’all asap!!

● Graphing linear functions means drawing straight lines on a coordinate plane using linear equations like y = mx + b. ● Find two points by plugging in x values to solve for y, then plot these points and draw a line through them

Impedance refresher.

[Click here for a PDF version of this post] Karl is taking his circuits course right now, which means that I get a chance to field some questions. I don’t get an excuse to think about this stuff any more. It’s fun material, since most of the ideas are all really simple, and you can figure out everything from first principles. Karl just started sinusoidal circuits, which I think is a bit exciting.…

Emotional Wounds and Functional Freeze: The Holidays

1/06/25 no energy and emotional wounds

Well we all know 2020 alone was super hard on everyone!!!! That year was hard to decorate for ANY holiday. Was also the year the unhealed trauma that I was unaware of, manifested itself physically and finally my gut gave way 😢 I had burning into my esophagus and I couldn’t eat for weeks!!!! Absolutely had to starve myself and lost over 25 lbs within 2 weeks… Everyone around me at the time got upset and started questioning me like crazy!!! I even tried to get into a Dr but it was heavy into Covid so… everything was about Covid and I couldn’t get help. People in my life still blame Covid for my situation and I don’t correct them 🥺🌹

Last Christmas in 2023, I fell off a ladder trying to hang up lights over my garage and I hit HARD, face planting on concrete and was nervous I broke my nose… THANK GOD nothing was broken that I know of but I had deep large bruises on my legs that changed colors for months and still if you press hard enough on my legs, I sorta can still feel it but it doesn’t hurt so much. THAT EXPERIENCE helped to mirror my unhealed emotional wounds 😭😭😭 That Christmas after I fell, it was super difficult to wrap presents or decorate cuz I was physically sore/tired and unsure what to do about my emotional wounds….

I had already made this blog and started writing down my story but didn’t understand why I was writing my story down…. I felt bad for making this blog and talking about my exes till I understand how important it is to process everything and talk about it. I needed to sort out my emotions and release everything I had been repressing!! As I continued to write though, I began to feel soooooo exhausted everyday. Almost zero energy and I push myself daily to get stuff done. (There was a traumatic death Feb 17th in 2024 also added to my plate)

This Christmas, all I wanted was lots of Christmas lights cuz it brings me joy but my family all begged me not to get on anymore ladders AND everyone was so busy, I couldn’t get them to come hang the lights for me, so I understood but was sad. I did get some lights up that I could reach and I did decorate inside but it all felt like a big chore. Buying Christmas gifts and wrapping them also felt like a major chore!!! Even though I wasn’t physically sore this Christmas, I just felt like I had to “get everything over with.” I mean, money has been tight since inflation, also stores closing down that I normally would shop at during Christmas…. So that was all sad. I LOVE Christmas it’s my fave holiday but it also always brings back bad memories of the Christmas I spent with my ex Andrew and the hurtful things he said…..

Now I’m taking down the decorations and ugggggh fudgin sucks!!! I just want it to be over with so I can get it off my plate. Part of me wants to throw a lot of it away but I know come next Christmas; I’ll wanna put it back out lol I would just leave it all up but eh, it’s over. Gotta accept Christmas is over. Just like I’ve had to accept my past is over. My exes are out of my life and they don’t love me. They only used me and hurt me. Idk why the wounds are so deep or why they take so long to heal. The impact alone from the emotional abuse has been CRAZY!! I’ve often wanted to pull my hair out and hide my face. Also, trying to get my energy back!!! It’s like in 2024, I just ….. am fried. Completely burnt out.

also this Christmas, I wanted to try makeup again and trying to style my hair and wore new dresses…. I just want to feel “beautiful” again…. Real beauty is on the inside but when you’re so exhausted and hurt, you struggle to feel any kind of beauty at all … there is a difference between humbling yourself and self-loathing. Gotta talk positively about yourself!! (Feels uncomfortable) Coming home to myself has been a journey separately in itself!! I am going to make it there and not give up!! Facing the demons of the past head on. Dismissing every lie my exes told me about myself with their brutal discarding!!! 🌹🌹❤️‍🩹
