https://schaechter.asmblog.org/schaechter/2021/05/prokaryotic-organelles-yes-there-are-such-things.html a blog post on prokaryotic organelles the entire blog is pretty neat if you're interested in bio stuff

>>96 E.T. Jaynes' The logic of Science A logic -> bayesian probability -> information theory angle of statistics. Absolutely love the way it ties everything together from that standpoint, possibly start with Shannon's A Mathematical Theory of Communication for the information-theory intro to entropy if you aren't familiar with the idea. I was a bench scientist forever and it really bothered me no one could adequately explain why we use certain things, like assuming the t or normal distribution for data without much reasoning. The principal of maximum entropy provides and easy answer (assuming a finite variance, the normal distribution is the maximum entropy distribution to assume) and it just fit so nicely.

so there's this funny DOI: 10.1002/(sici)1097-4628(19981205)70:10<1939::aid-app8>3.0.co;2-g "Investigation of Alkaline Hydrolysis of polyethyelene terepthtalate by differential scanning calorimetry and thermogravimetric analysis" no idea how calorimetry works and why ppl use it but that's not what matters this paper was made by happas in the past century and can be summarized as "we tried to recycle plastics, it works" the plastic is called PET and it's basically 1,4 butanediol and terephthalic acid and 1,4 butanediol metabolizes into GHB inside of your body in a few minutes which makes GABA stuff in your brain spin right round insanely fast way better than alcohol and those red mushrooms so yeah if you don't like brewing or despise alcohol you can still easily fuck up your brain at home using plastics and toilet cleaners though hydrolysis takes a lot of time 10 grams of PET can take you like six or eight hours i recommend speeding things up by adding a bit of ethanol as a catalyst to your NaOH solution (KOH decomposes 1,4 into an unfunny glycol ) oh yeah there's also that terephtalic acid it's not "toxic" but there are lots of it you may want to remove it and most of the other nasty stuff by adding sulfuric or hydrochloric acid until the participate won't stop forming (stop as soon as it forms or you will burn your stomach) it also looks really cool you just one little drop and lots of crystals appear the participate is the nasty stuff just filter it out through a toilet paper and throw it away well it's kinda useful for other things maybe leave it 1,4 can be easily converted into GBL and then GHB but only the letters change effects are the same (and GHB is a salt while others are liquids) there was that one cool paper on dehydrogenation of 1,4 that yields GBL but i kinda lost it in my file directory labyrinth oh and yeah i just did some math 10 grams of pure PET will yield around 3/4 grams of 1,4 which is like two doses for non-tolerant people also some PETs have some brominated stuff that makes it hard to burn and that's really bad because ingestion of brominated things leads to a horrible death from cancer and it's almost impossible to filter those brominated things out so check how well your plastic burns before using it maybe i'll make a proper step by step guide later yeah i guess i will parody that asuka's meth lab webm someday too lazy rn

>>

>PET >it's basically 1,4 butanediol and terephthalic acid oopsie woopsie i made a fucky wucky so yeah plastic that's actually a 1,4 butanediol and terephthalic acid is called PBT and you should use it instead PET will yield some 1,4 but most of it will be 1,2 and 1,3 fuck i should proof read what i write

Would it be possible to make a microwave that allows you to heat with metal utensils inside?

>>

>>112 Yes, but ovens take forever. I'm talking about a quick and convenient way of heating.

>>113 Use an air fryer

>>

>>110 They should make an alternative way of heating Works similar to a microwave and is fast But is able to keep metal utensils inside

>>

>>122 Just use plastic utensils, or take the metal utensils out..

what books have you read recently, hikarin? what is your go-to literary interest? what's your reason for reading it? talk about fiction or nonfiction, academia or entertainment, everything in between, as long as you find it interesting. however, discussion of manga and comics should be kept to the /jp/ board. e-book resources: https://annas-archive.org/ https://libgenesis.net/ https://sci-hub.se/ https://archive.org/ https://openlibrary.org/ https://www.gutenberg.org/

>>489 Wouldn't that French aristocracy in question actually also be the left, too?

>>

>>489 >>490 Per the definition around the markets*

>>

sorry guys this has nothing to do with the thread but it came to mind what the fuck is up with farmers? like all of their crops and shit gets bought by the same enormous corporation, whats the poont of engaging in business when you dont have access to the bartering process that's fundamental to a market?

>>

>>491 Exactly my point, Hikarin! It’d be crazy calling the French conservatives and reactionaries leftist, but the market definition (because it takes our current world and political problems for granted) makes it seem like monarchist traditionalism could be leftist. Another example (I got this from Racecraft too but it’s the book I’m reading right now so still on topic!) is the set of antebellum southern planters who argued slavery was better ethically than capitalism. Their argument was basically conservative and paternalist, but many of their descriptions of capitalism can read as surprisingly left wing if you ignore what they thought was better.

>>

>>491 >>493 Isn't right-wing vs left-wing mostly about linking social hierarchy to property? Like rightists believe wealthy individuals and families have demonstrated their ability to preserve and grow value so it's fine if they run the show, but leftists believe this is an arbitrary and unethical way that leads to inefficiency and instability.

We post about our research group meetings. >someone can't get something basic to work, the professor tries to do some light troubleshooting then and there, but this makes the presenter nervous and they start to spill spaghetti >someone went over their time and talked for hours about nothing I have my research group meeting this Friday and I've barely started on implementing the control algorithm I said I'd have done. Please shoot me.

>>

>>410 What exactly do researchers do on a day to day basis?

>>

Hikarin, nobody here is smart enough to be part of a research group. cry

>>

>>432 Read papers, interpolate a research project between the most recent papers, design an experiment, run the experiment, write up a paper, repeat.

>>

>>410 The only time I was a part of a research group, I had to do everything myself.

>>

>>482 iirc in elementary the kids in my group were never recognizing that there was an optimal way to work the given essay or whatever, so i would be doing my own while they fucked around, it might have been the main language class where i submitted my own thing (that was miles better than what the other retards made) and the teacher gave me my first non-passing grade because i didnt cooperate lol

imagine if money, intelligence, focus, health, time, and other circumstances weren't a problem. what would you dedicate your life to studying? why does it fascinate you? as for me, i've always wanted to study brains. pick apart this dense mass of flesh that somehow encodes the human soul. i want to be a part of the science that's trying to map brains to computers, interpreting synapses with machine learning and using algorithms to model neural circuits. look closely at how information is processed by the brain, and maybe even try to analyze those heuristics to understand myself a bit better. my excuse is that i'm too dumb and not good enough at chemistry. i just can't commit. who knows, maybe i'll regret this fear of mine forever. i wanted to hear about your unsung passions, too

I would study applied metaphysics aka magic been reading the traditionalist school guenon, schuon, coomaraswamy, evola and evola's books on magic seem pretty cool, buddhist magic also seems pretty cool

>>302 Buddhist magic?

>>

>>302 >I would study applied metaphysics aka magic You know it takes alot of beleif and faith for atheism when all new atheists do even on imageboard boards is regurgitate what their group or favorite atheist says.

>>

>>268 >what would you dedicate your life to studying? why does it fascinate you? Difficult question for me. I believe I'd like to just study anything like philosophy, mathematics, religion and new atheism (even if it's shallow minded anyways) ect. It would just be fun to play video games I suppose and programming if money wasn't a problem or really any academic field.

>>

>>268 Same thing I'm studying now

I was self-learning Russian for a bit but I am nowhere able to construct more than a few basic sentences. cry Now I'm unsure whether I want to continue or learn Spanish instead. I know some people close to me who speak Spanish themselves and it seems more practical with how widely spoken it is. I'm indecisive.

Personally, I like switch-reference cases. https://en.wikipedia.org/wiki/Switch-reference

>>28 I'm too drunk to talk about linguistics but I dropped out of a masters in this so I know more about anyone else in this thread AMA

Currently in 2nd year of BS Information Technology; graduating by the end of 3rd Year. I only got 2 GitHub projects, both of which are crappy and nothing to show for. I don't know whether to apply for an internship early, or wait for the school to offer/assign one for us.

>>

>>388 >I only got 2 GitHub projects i relate to this so so much. do companies usually want 5+?

>>

>>335 My luck was against me when I picked my uni because they never told us we would need to grind certificates or show off some github as portfolio. I never had any well untill I finished my master's neco

>>

>>389 Jobbing at a tech interview is a bigger concern and would invalidate even 10 projects

>>330 hi math-anon. do you have any book recs for real variables that aren't rudin? it's extremely terse and dry and doesn't really motivate much it covers so i want to supplement it i was thinking of going through apostol or abbot but neither seem to cover lebesgue theory or multivariable functions as far as i know
