I should be reading my book on organic chemistry because I have the exam in like a month and I haven't learned shit yet bc my professor fucking sucks. But why does the book have to be so... idk, it's not even really boring cause I do find it kinda interesting how different groups in molecules affect the reaction but like... the reality and act of having to actively try and learn all this, just SUCKS. I don't want to memorize all these stupid mechanisms and then when you adjust the temperature something totally different happens and I need to know that. Not even that, I need to be able to tell what reaction happens based on the reactants and like... I wouldn't mind knowing that, but I also wouldn't mind if I didn't but I'll fail my exam if I don't. I just really don't want to put in the work because I don't like it enough because it's fucking organic chemistry and of course I have to do FOUR FUCKING SEMESTERS of this shit and I'm already hating the first WHYYYYYY 😭😭

In 1942, a team led by chemist Louis Fieser originally developed napalm for the US Chemical Warfare Service in a secret laboratory at Harvard University. The name “Napalm” is a portmanteau of two of the constituents of the original thickening and gelling agents: naphthenic acid and palmitic acid. The addition of these two helps gelatinize combustible materials like gasoline, which then sticks to surfaces and burns, causing more damage. Napalm was widely applied by the US during the Korean War for close air support.  It also became an intrinsic element of US military action during the Vietnam War. Reportedly about 352,000 tonnes of napalm bombs were dropped in the region within 10 years. The image shows a girl named Phan Thị Kim Phúc at nine years of age running naked on a road after being severely burned on her back by a South Vietnamese napalm attack.

naphthenic acid

Naphthenic acids (NAs) are a mixture of several cyclopentyl and cyclohexyl carboxylic acids. NAs is mainly used in the soap, textile and leather industries. It can also be used in the manufacture of disinfectants and insecticides, or in the manufacture of dry agents and brighteners for the paint and coating industry. NAs soap is also a good emulsifier and it is widely used to prepare lubricating coolant for metal working.

palmitic acid

Palmitic acid, or hexadecanoic acid in IUPAC nomenclature, is the most common saturated fatty acid found in animals, plants, and microorganisms. As its name indicates, it is a major component of the oil from the fruit of oil palms.

oh wow hey it looks like i need to average a 92% on every quiz + the final for the rest of this physics class if i want to end with an A. that’s. wonderful really. just superb

[t00thpasteface]

only about a month away from moving back into my dorm, so here's a little behind-the-scenes to celebrate. behold two bio majors who are entrusted with handling scalpels

roommate took a stupid selfie and i photobombed it holding up my elvis themed cup. then i redrew it. and then i showed this redraw to my roommate and she said we should name each other Trapper and Hawkeye in our phones. but bc we sleep in the same room and spend all day at the same campus we really only text each other "are you out of class yet" "do you want to get lunch" "are you still in lab bc i want to get sandwiches" "i'm in the cafeteria where are you" "i'm omw to the caf is the food good today?" "no"

First Impressions 🎀

I've had 4 of my 5 classes so far (one doesn't start til october) and I definitely have some thoughts on them, so I thought I'd share my first impressions!

Principals of Accounting II:

the professor seems a bit disorganized, nervous, and semi chaotic but I like his energy

so many people in southern attire, I was a bit surprised

might take a decent amount of study time and energy to keep my grade up in the class, but I'm always up for a challenge and I definitely know I'm capable

gotta figure out a time efficient study routine for this class

Learning (Psychology)

professor has an accent, no idea where he's from, but it's a cool and thankfully understandable accent

feels very content heavy. I definitely want to buy the textbook for this class

need to find a way to stay awake, that's one of the classrooms that make me sleepy

that professor likes to talk for sure (1 hour and 15 min of just the syllabus? man's can talk)

Integrated Survey of Organic and Bio Chemistry

the professor is definitely a science guy, him being the professor makes perfect sense

i really like how he explains and teaches

appreciate that all the content needed is already posted to our class online and all the slides are available already

I love science based classes because I know how to succeed in them and this one seems no different

I have a friend in the class so that's nice!

Intro To Business (Online)

lots of content

lots to do

I gotta make sure I time manage for this class cause otherwise, I'm gonna fall behind

an introduction video?? why not just a discussion post?? ahhhhh

Overall, with working full time, this is going to be an incredibly stressful, incredibly busy semester, but I'm so up for the challenge, and I know I can do it. I just gotta study efficiently, time manage properly, and keep disciplined. I WILL be successful.

til next time lovelies 🩷

— Pinnacle [ tsukishima kei university au series ]

— so i pay the price of what i lost ; yes it is right that you can handle anything, but you can’t handle everything all at once

author’s notes : no mention of (y/n), written in second person pov, alternative universe, timeskip!tsukishima, college life, not proofread, english is not my first language, long written chapter

[ masterlist ] | [ ask daleelah go to box box 🐭 ]

Winter break felt like a blur of constant assignments, stress, and messages from your mother. You found yourself buried in work, avoiding the outside world—especially your phone, which you knew was filled only with your mom’s relentless reminders to study harder, do better, and aim higher. Tsukishima and Yamaguchi’s contacts had been pushed to the bottom of your recent conversations, untouched since that day in the gym.

You haven’t seen Yamaguchi or Tsukishima since that winter class you skipped to watch their game. That day feels like it happened in a different life—before the semester started to suffocate you, before your every waking moment was consumed by endless biochemistry coursework. You don’t have time to think about anything else anymore, not when every day feels like a battle to keep up with the expectations of your professors and the relentless academic pace.

Classes in the second semester are intense, perhaps even more than you expected. One of your courses, Organic Chemistry II, is particularly demanding. The subject matter dives deep into reaction mechanisms, synthesis pathways, and the stereochemistry of complex molecules. There’s also Molecular Biology, where you’re expected to learn and apply the intricate processes of DNA replication, transcription, and translation. Your third major course, Biophysical Chemistry, focuses on the thermodynamics of biological systems—another subject that stretches your mind to its limit.

It’s only the second week of your new semester in biochemistry, but it feels like you’ve been dragging yourself through months. Everything seems heavier this time—every lecture, every lab session, every assignment. The moment you open your textbooks and class notes, you can feel your brain protesting. There’s an exhaustion that hangs in the air, a feeling like you’re constantly one step behind even when you manage to complete your work on time.

Now, standing outside the lecture hall for Organic Chemistry II, you realized nothing much had changed. The same heavy textbooks, the same tight deadlines, the same competition between your classmates as they all tried to one-up each other. The new semester had brought a new intensity. You were still trying to keep up with your classmates—some of them seemed almost unnaturally gifted, answering the professors’ most complex questions with ease, while you constantly second-guessed yourself, even when you knew the answer.

Professor Saito, a man with a greying beard and an air of calm authority, strode into the room with his usual collected demeanor. His reputation preceded him—tough, no-nonsense, and known for pushing his students to think critically. Today was no different. He picked up a piece of chalk and began scribbling a chemical equation across the board.

Without glancing back, he posed his first question to the room. “Can anyone explain the significance of this reaction in the context of anaerobic respiration in yeast?”

The classroom, filled with second-year students, was eerily silent. Your eyes traced the chemical formula on the board—glucose breaking down into ethanol and carbon dioxide. The answer floated on the surface of your mind, but your heart pounded in your chest as self-doubt crept in. You scanned the room, hoping that one of the top students would break the silence and offer the answer instead. But they remained still, unfazed, as if this question was beneath them.

You bit your lip, feeling the weight of the quiet hanging over you. It was a simple question, one you knew the answer to, but something held you back. You hated this feeling—knowing, yet hesitating, paralyzed by the fear of saying something wrong. The silence stretched on, and finally, despite the knots of anxiety in your stomach, you slowly raised your hand.

Professor Saito turned to face you, his gaze resting on you with a slight lift of his eyebrows. “Yes?”

Your voice wavered as you spoke. “It’s… the fermentation of glucose into ethanol and carbon dioxide,” you said quietly, swallowing back the stammer in your throat. “Yeast uses this anaerobic process to generate energy in the form of ATP when oxygen isn’t available.”

Professor Saito nodded slightly, his expression unreadable. “Correct. And why is this process significant in industrial applications?”

You took a deep breath. “It’s used in brewing to produce alcohol and in baking for the carbon dioxide that helps dough rise.”

He considered your answer for a moment before nodding again. “Yes. Good. Remember, however, that the ATP yield here is significantly lower than in aerobic respiration. That’s the key difference.”

Relief washed over you, and you allowed yourself to relax—just a little. But before you could even savor that small victory, another voice broke the quiet.

“Professor, could you explain the exact mechanism for the stereoselective alkylation of an enolate in asymmetric synthesis?” The voice belonged to Renji, one of the top students in the class. His question was sharp and cutting, a deliberate challenge. “And maybe elaborate on the difference between kinetic and thermodynamic control in that context?”

A ripple of murmurs spread through the room, punctuated by a few suppressed giggles. You stiffened in your seat. The question was far beyond the scope of what you’d covered in class, meant to impress—or worse, embarrass—the professor. Renji’s tone dripped with arrogance, and the way he leaned back in his chair, arms crossed, told you he already knew the answer.

Professor Saito regarded him for a moment, his gaze steady. He began to respond calmly, “In asymmetric synthesis, the stereoselectivity of the alkylation depends on—”

Before he could finish, another voice interrupted. “What about stereoelectronic effects when using Evans' oxazolidinone in highly hindered substrates?” Yumi, another top-tier student, chimed in with a smirk playing at the corner of her lips. She leaned forward slightly, her question laden with the same smug intent—to derail the lesson, to show off her own knowledge.

The air in the room became stifling. You could feel it—the discomfort rippling through the other students, the growing tension as Renji and Yumi sought to outwit the professor rather than learn from him. They weren’t asking to deepen their understanding. No, they were playing a different game, one of one-upmanship and arrogance.

Your stomach twisted with unease as you watched the scene unfold. Professor Saito, usually unflappable, seemed to falter for just a moment. You caught a glimpse of weariness in his eyes as he straightened up, preparing to answer yet another convoluted question. He had always been patient with his students, no matter how difficult the questions, but there was something in the way his shoulders sagged ever so slightly that made your heart ache for him.

You glanced around the room. Some students were fidgeting uncomfortably, others quietly whispering to their neighbors. The whole room had been hijacked by these few who cared more about showing off than learning, and the rest of you were left feeling small, inconsequential. You clenched your fists under the desk, wishing you could say something, do something to stop it, but the words stayed lodged in your throat. What could you say? What could you do?

Professor Saito began explaining the stereoelectronic effects, his voice steady, but you could sense his weariness growing. The air felt oppressive, like the weight of these students’ arrogance had smothered any genuine learning atmosphere. You shifted in your seat, feeling anxiety gnawing at your insides, hating the smug smiles that played on Renji and Yumi’s lips.

Before you could think further, you raised your hand signaling to interrupt the class. Professor Saito caught your motion and stop his explanation. “I’m sorry, Professor, may i speak?” Your voice came out a little shaky but louder than you expected, you can’t stop yourself right now. Every eyes are on you when the professor nodded. You land your gaze to Yumi—her smug faltered as she turned toward your seat. “I don’t see any stereoselective alkylation of enolates in asymmetric synthesis in our syllabus for this entire semester. So, if you’re going to interrupt the class with questions, at least stick to the topic we’re actually supposed to be learning.”

And now you turned to Renji’s seat, his face hardening as the room went deathly quiet. You could feel the eyes of the other students on you, and though your heart pounded in your ears, you pressed on. “And if you’re feeling that generously smart, maybe you should come up there and be the professor yourself. But what do you actually get from trying to make others—let alone the professor—feel small by throwing out questions just to outsmart them?”

Yumi’s smirk vanished, replaced by a look of shock. Renji shifted in his seat, his face hardening, but he remained silent. You could feel the tension swirling in the room, but it wasn’t directed at you anymore—it was directed at the arrogance that had poisoned the air.

Professor Saito stood there for a moment, his expression unreadable. Then, slowly, a small smile tugged at the corners of his lips. He cleared his throat, and the room snapped back to attention.

The room goes quiet, tension crackling in the air. You don’t usually speak up like this, but something about the arrogance in the room pushed you past your breaking point. The student sneers at you, but you don’t flinch. You’ve had enough of people trying to make others feel small just to inflate their own egos.

Professor Saito gives you a small nod of appreciation before continuing his lecture, the class quiet now except for the sound of his chalk against the board.

That evening, you’re back at your desk, struggling to finish another assignment. The words blur together on the screen, and despite your best efforts, you keep having to re-read the same paragraph over and over. You’re exhausted. There’s no other word for it. Even though you’ve tried to catch up on sleep, it never feels like enough. And there’s always another deadline looming, another mountain of work to climb.

Your phone buzzes next to you, but you don’t pick it up. It’s probably your mom again, asking why you haven’t called or berating you for not keeping up with her expectations. You’ve been avoiding her texts and calls lately because you can’t deal with the added pressure. She doesn’t understand how hard this is, how much you’re trying to juggle. Or maybe she does, and just doesn’t care. Either way, you don’t have the energy to explain yourself to her right now.

By the time you finish the assignment and hit submit, it’s nearly 2 AM. You slump back in your chair, staring at the ceiling. Every muscle in your body aches, and there’s a tightness in your chest that hasn’t gone away for days. You feel like you’re sinking deeper into a hole you can’t climb out of.

The thought of opening your phone again fills you with dread, but you do it anyway, more out of habit than anything else. When you do, you see an email from Professor Saito.

Subject: Checking In

I hope this message finds you well. I noticed that you submitted your most recent assignment late last night. While I am aware of the pressures you and many other students are under, I wanted to reach out personally.

Over the past few weeks, I’ve noticed how diligently you’ve participated in my class. I’ve seen how you’ve quietly answered questions, even when you seemed uncertain of yourself. I also noticed how you stepped in during that difficult class discussion the other day and helped refocus the conversation. You have a sharp mind, and I hope you know that.

That said, I am concerned about you. I can tell that you’re pushing yourself hard, and while I appreciate your effort, I also want to remind you that your well-being comes first. I know what it’s like to feel the weight of academic pressure, and I want to encourage you to take care of yourself, too.

If you ever feel overwhelmed or need to talk, please know that my office door is always open to you. You are a valued member of my class, and I believe in your potential.

Take care of yourself, and don’t hesitate to reach out if you need anything.

Warm regards, Professor Saito

As you read the email, you feel a lump form in your throat. You hadn’t realized how much you needed to hear those words until now. For so long, you’ve felt like you were just going through the motions, never sure if you were really doing anything right. But here, someone was telling you that you mattered—that your efforts weren’t invisible.

You close the email and stare at the screen for a long moment. Then, without thinking, you bury your face in your hands. The tears come quickly, a mix of exhaustion, relief, and gratitude. You hadn’t expected this—this kindness, this small bit of recognition in a sea of doubt.

MCSR As Chemical Compounds

idk either man. expect very little actual explanation and a lot of chemical yapping from a very big nerd

Silverr as Silver Nitrate:

AgNO3

the above is the crystal structure

appearance is just a white crystal kinda like sugar

it took everything in me to not just make silverr plain Ag

silver nitrate is the most common precursor for all other important silver salts

also an extremely important compound in the development of photography! (and iirc silverr is a film major)

Feinberg as Ozone:

O3

produced during lightning strikes

pale blue at high ppm

only leaves gas state at cryogenic temperatures

naturally occurring in the stratosphere and absorbs UV rays from the sun

Fruit as Nickel(II) Chloride Hexahydrate:

NiCl2•6H2O

green

the non-hydrate form is a sort of olive-y yellow color

used to absorb ammonia in gas masks

Raddles as Potassium Permanganate:

KMnO4

Sometimes referred to as Purple Potion Powder

goes CRAZY purple when dissolved and is lowkey my favorite chemical

very strong oxidizing agent

one time i stained my hand purple through my glove with this shit idk how it happened

if made in specific solvents can look extremely similar to dragon's breath in minecraft imo

K4 as Octathio[8]circulene:

C16S8

also referred to as Sulflower (like sulfur and sunflower haha get it)

planar which is fairly uncommon for molecules of this size

can be stacked together to make sheets of sulflowers

Cube as Cubane:

C8H8

yeah this is self-explanatory

what is interesting though is that ring strain in 4 membered rings/squares is really high, so cubane existing is a bit of a chemical anomaly

i havent read into it enough to know for sure but i suspect that ring strain is why cubane is a precursor to a HELLA STRONG explosive compound

Reignex as PPTA:

Poly-p-paraphenylene terephthalamide

[-CO-C6H4-CO-NH-C6H4-NH-]n

the name is complicated as shit but this is just kevlar!

aka bulletproof vest material

looks fluffy when not woven completely together

aligning of polymer chains w hydrogen bonds creates EXTREMELY high tensile strength

Mime as Phenylmagnesium Bromide:

C6H5MgBr

a common grignard reagent aka a compound that can be used in a grignard reaction, an extremely important reaction in organic synthesis as it creates new C-C bonds

another fun fact about grignard reagents is that if water is added to them- or even if they're handled in particularly moist air- they fucking explode

extremely strong nucleophile and base

Poundcake as Xenon Hexafluoride:

XeF6

Noble gases don't react unless you REALLY make them

so a compound containing xenon is really interesting

colorless as a solid but sublimes (aka skips straight from solid to gas) into a bright yellow gas

fun fact a lot of instances where typical chemistry rules are broken (noble gases not reacting, octet rule in general, etc) involve fluorine to the point ive heard it referred to as a "batshit electron thief"

Fulham as Iron Hexacyanidoferrate:

C18Fe7N18

also known as prussian blue

extremely common pigment in paints and the first modern synthetic pigment

used extensively in The Great Wave

another one of my favorite molecules bc im biased and like inorganic chem aka things that contain metals

used as an antidote for heavy metal poisoning which is interesting bc it contains cyanide ligands!

Couriway as Bullvalene:

C10H10

in a state of constant resonance

aka the double bonds are CONSTANTLY shifting and reforming bullvalene into... itself but moved around a little

the bonds fluctuate so rapidly that in nmr analysis each carbon and hydrogen in the entire molecule is read as equivalent (for my non-chem people that's very uncommon and very cool)

formed through photolysis (aka using light/photons to fuel a reaction)

[polskapika]

(iv) phylum: chordata from animal kingdom + did examples from phylum: annelida → hemichordata.

★ studied 'respiration in plants' from plant physiology.

hi y'all! good day, got a lot done in biology! did a satisfactory amt. of chemistry too, but kind of neglected physics unfortunately :( i'll try to wake up early tmrw and do numericals since that's a weak point that i need to get done with. mentally felt okay, also worked out so there's that :) i think it's slowly dawning on me that NEET is exactly 4 months away, so i need to get my shit together and buckle up lol. i'll be having exams till the 19th, so after that i'll try finishing up with the XI syllabus + XII syllabus (partially) if i can. (without compromising my understanding of important concepts)
