Matrix Multiplication - Ex. 2

maybe maybe a mistake taking astronomy; idk why I thought I'd suddenly be a physics mastermind just bc I have more motivation for it now. It's the first week and I have no actual clue what I'm doing (or more accurately: should be doing. Mostly so far it's been lots of staring and muttering of "what the fuck" in regular intervals)

AAAAAAHHHH I HAVE A MATH TEST TMRW

Normally, I’m not so stressed, but I missed class this week (I was skipping shame on me 😭) and I have no clue what’s going on… Me and the math teacher are besties because he’s the coach of the golf team, so I’m scared of disappointing him with my bad test scores.

I also had a long lab in chem this week. It’s really sad because we got bad results even though we ran our trial for over and hour lol. I think it’s my lab partner’s fault because he keeps on putting his crusty fingers all over the cuvettes which is messing up the spectrophotometer. Hopefully he actually writes his part so it’s not another repeat of last year.

- Practice midterms for matrices

- Grade practice midterms

- Write lab report

- Debug binary system simulation

- Work on astro research paper

- Work on program applications

- Finish new deal research

- Finish college assessment

- Email people back 😬

Don’t ask me why we have a midterm in January… I have no clue.

yesss, chuck that horror show of indices away

DM me for proof :3

It is absolutely amazing how much upper div computer science/engineering relies on vectors and probabilities, considering those two classes were basically footnotes in my school's computer science curriculum

Post-Lecture Pondering #2:

What are some common (pure mathematics) applications/uses for block-diagonal matrices? Also, what (generally) are some interesting properties about them?

Additionally, what could you say about an “increasing block diagonal matrix,” where the non-zero submatrices of a square n x n increase from dimension 2 x 2, 3 x 3, ... , n/2 x n/2?

i swear to fucking god if i have to write one more fucking matrix...

i might have already posted about this a while ago but my favorite ace experience is adapting allosexual terminology for myself (because my friends use it, so i automatically pick it up too) without actually understanding what it means (like i know what it means literally, i just don’t understand the feelings)

what i say: “that’s hot!!” or “oh my GOD that’s so attractive”

what i mean: that is aesthetically pleasing, or it makes me feel safe & happy

what i say: “-5 shots to fuck them”

what i mean: i feel joy about this person!

truly my best brain time is in the middle of the night caffeine & sugar rush. I think I just understood math, like some part of the general pattern of math if that makes sense. something clicked somewhere in my brain and I felt it

so i see your tags on bats post and hm hm hm…

listen. realistically i could see both of them slaying the game in every branch of engineering, and i do respect your opinion. i hold you to the highest regard darling, however you’re incorrect.

you cannot tell me that sirius black - who invented a flying motorcycle for fun - is not absolutely entrenched in mechanical or aeronautical engineering. that bitch is obsessed with machines and moving parts and what comes with that??? physics. she loves physics.

james on the other hand i could see going anywhere. i do like the idea of her being a coding genius but that also feels too boring on its own so let’s give her something chemical or biomedical engineering-y, because you code in all branches of engineering!! i just think that if either of them is going to explode shit, light something on fire, invent bionic arms, it’s her. and she also codes her own games on the side for fun (and because she can sit in sirius’ lap and bounce ideas off of her when she does)

they both work in the same space and the content of engineering overlaps so much that they’re never out of touch with each other. it’s sort of like paralell play, and maybe they fuck up matrices together.

anyways sorry i kinda went off, i have a passion for this topic. i’d love to hear your ideas too <333

Okay fair point about the motorcycle, I did forget about that. I mean you do need chem for that, but yes it’s physics so maybe Sirius does both. I still like the idea of her being walter white tho

ALSO EXCUSE YOU CODING ISNT BORING (it is kinda boring actually but that’s my field i have to defend it).

Jamesy seems like a probability wizz actually. Maybe in ur casino au shes a card counter. Sirius is on her arm watching, knowing exactly what’s going on but she doesn’t really care cause that means james can buy her a drink later!!

OH MY GOD sirius is the dealer, james is a card counter. Thats so hot actually.

Got distracted, anyway james seems like she creates probability algorithms, like a quant, and does game dev on the side. Sirius checks her code and finds the random colon she forgot then holds her while she cries about it.

Okay so, Sirius gets mechanics, James gets statistics and they check each others work and do puzzles together like nerdss <33

30 minutes into speedrunning matrices and i get why the Matrix guys wanted to get out
