Excuse me, but why are math textbooks so expensive!?!? It's like 50$ a piece for these things. Jfc bros. And before you say "pirate them online", what if I want a hard copy to read? It's so much money.
>>16166695>wouldvewouldnt*btw that pic is the thriftbooks order i was referring to, looks like it was actually $10, free shipping.
>>16166695my bad, it was $15
>>16166683Those are all out of date though
>>16166737very funny, retard
>>16166737Out of date? What kind of math are you trying to learn that's new enough that you're worried about it being out of date?
Moomin editionLast thread >>16140594We discuss research, DO NOT offer advice (just fucking go see your doctor), make fun of premeds and shitpost.Keep vaccination/clamping/vitamin K/soliciting advice out of this thread and start your own because it takes a lot of space.
>>16166622>Idk what specialty I'd like though.I'm sure you'll find something you like during school. How have you been spending your time from being accepted until your matriculation? I remember that time finally being a break from the application cycle and I just relaxed.
>>16166628Been doing a masters at a pretty good uni. I won't say which for obv reasons, but I'm graduating from that on Saturday. After that, taking a vacation back to the old country, and maybe I'll stomp around in Japan for a week or two. This week I'm just melting my brain on modded skyrim and cooking every dish I never had the time to make during the school year. I never knew how easy it was to make pie crusts once you get the technique down. Wings have been another massive success.
>>16166514Enjoy your freedom now. You cannot prepare. I am not joking. Congrats homie
Sorry for the long post. but can I get any advice on leaving medical school? I'm currently studying for my second exam of M2 and I really hate it. I always wanted to work in a technical job in weird or remote places, like telecom technician, oilfields, merchant marine, etc... but opted to keep pushing during premed because I reasoned I could find rural or international work as an attending.Now I realize I don't enjoy biology, suck at clinical skills, and have much less passion for the field than any of my peers. Thank God I've been academically okay so far, but really burnt out and I have 3 more years + step exams. I don't want to start again or disappoint my parents, what do i do bros?

Are brain eating worms real? If so how do you avoid them? https://www.foxnews.com/politics/rfk-jr-said-worm-ate-part-his-brain-and-died-his-head>RFK Jr said a worm ate part of his brain and died in his head>RFK revealed in a 2012 deposition that he also suffered from mercury poisoning
>>16166706Yeah, but the first step to getting brainworms is getting intestinal tapeworms from undercooked cysts in pork, then going ass-to-mouth>Cysticercosis [brainworms] is usually acquired by eating food or drinking water contaminated by tapeworms' eggs from human feces>Among foods egg-contaminated vegetables are a major source. >The tapeworm eggs are present in the feces of a person infected with the adult worms, a condition known as taeniasis [gut worms].>Taeniasis, in the strict sense, is a different disease and is due to eating cysts in poorly cooked pork.

In Latin America, an estimated 75 million persons live in endemic areas and 400,000 people have symptomatic disease.[67] Some studies suggest that the prevalence of cysticercosis in Mexico is between 3.1 and 3.9 percent. Other studies have found the seroprevalence in areas of Guatemala, Bolivia, and Peru as high as 20 percent in humans, and 37 percent in pigs.[68] In Ethiopia, Kenya and the Democratic Republic of Congo around 10% of the population is infected, in Madagascar 16%. The distribution of cysticercosis coincides with the distribution of T. solium.[69] Cysticercosis is the most common cause of symptomatic epilepsy worldwide.[70]Prevalence rates in the United States have shown immigrants from Mexico, Central and South America, and Southeast Asia account for most of the domestic cases of cysticercosis.[71]

How do vaxxxies feel knowing that their life expectancy has been substantially reduced by their decision to take an untested medicine for a nonexistent viral epidemic? Foolish? Are there any vaxxxies on /sci/ that aren't too massively egotistical to admit that they got tricked and made a mistake by volunteering to a a guinea pig and doing it for free too?
>>16165251>Are there any vaxxxies on /sci/ that aren't too massively egotistical to admit that they got tricked and made a mistake by volunteering to a a guinea pig and doing it for free too?No, the vax scam specifically targeted people with highly narcissistic personalities

In my country we had reverse DEI, the rich built legal moats around their wealth and privileges and kept most people out. It wasnt just about their own money, but about controlling public assets, national resources, etc. It also failed since it wasnt selecting for the best, only for those in the club.

I know one case where whole family (parents + daughter) died taking Astrazeneca. that's why I opted for mRNA.I even hedged my bet by splitting my shots between of Moderna and Pfizer so the possible (bad) effects average out.
>>16164789if you took it years ago and haven't been bosting you probably would've noticed by now if something was wrong. unless the turbo-cancer meme is real and has more basis then just "cancer line go up", then I'd be worried. not sure what you can do in that case though, I don't think you can easily walk right into a doctor's office and get a detailed and accurate full body screening with 0 symptoms
>>16164789pfizer and moderna are mrna based vaccines, the astra vaccine is not mrna based and as a result carries some of the risks that covid does (in this case, clots)this isn't even the reason it got withdrawn, it's cuz it couldn't compete

I officially have an Erdos number of 2, anons!Does anyone else have an Erdos nunber?
Seriously, mine is 5. Not great, not terrible.

>>16165001Someone being proud of being part of a group?That sounds like potential identitarian thinking.And that sounds like anti-semitism to me.>Early lifeNevermind.
>>16165001Described by his biographer, Paul Hoffman, as "probably the most eccentric mathematician in the world," Erdős spent most of his adult life living out of a suitcase.[19] Except for some years in the 1950s, when he was not allowed to enter the United States based on the accusation that he was a Communist sympathizer, his life was a continuous series of going from one meeting or seminar to another.[19] During his visits, Erdős expected his hosts to lodge him, feed him, and do his laundry, along with anything else he needed, as well as arrange for him to get to his next destination.[19]BAHAHAHAHAHAHAAHAHAHA!Oh, Epstein knew what he was doing. Phenomenal.
Bad news fellow vaxxies, the "turbo cancer" rumor that the conspiracy theorists have been yammering about has turned out to be completely true, as proved by this recent publication:https://pubmed.ncbi.nlm.nih.gov/38234925/>The "hallmarks of cancer" were proposed by Hanahan and Weinberg (2000) as a group of biological competencies that human cells attain as they progress from normalcy to neoplastic transformation. These competencies include self-sufficiency in proliferative signaling, insensitivity to growth-suppressive signals and immune surveillance, the ability to evade cell death, enabling replicative immortality, reprogramming energy metabolism, inducing angiogenesis, and activating tissue invasion and metastasis. Underlying these competencies are genome instability, which expedites their acquisition, and inflammation, which fosters their function(s). Additionally, cancer exhibits another dimension of complexity: a heterogeneous repertoire of infiltrating and resident host cells, secreted factors, and extracellular matrix, known as the tumor microenvironment, that through a dynamic and reciprocal relationship with cancer cells supports immortality, local invasion, and metastatic dissemination.

>>16145861Feels good to be a pureblood.How many of the vaxxxxies of /sci/ are jealous of me?
>>16164958they won't admit to being jealous because they're ashamed of themselves for having been so easily tricked into taking an untested experimental medication for a nonexistent viral epidemic. nobody wants to be seen as a gullible, easily manipulated, low iq sucker

>>16166606That given explanation is fucking atrocious. It completely skips over what it's actually doing and why it's doing it.Trying reading this pdf. The third section is all about powers of 7 and finding their last digits, and it covers why mod 4 is used.
>>16166638You know Euler's theorem, right?https://en.wikipedia.org/wiki/Euler%27s_theorem[eqn]\varphi(10) = 10(1 - 1/2)(1 - 1/5) = 4[/eqn]So [math] 7^{4} \equiv 1 \pmod{10}[/math]Now just using this you get that [math]7^n \equiv 7^k \pmod{10}[/math] if [math]n \equiv k \pmod{4}[/math].Basically you can reduce the exponent mod 4.It's northing special about powers of 7. It will work with powers of all numbers that are coprime to 10.

How do u guys find math fun?What about it makes u love it
>>16166697I'm an INTJ so I don't so much love it as see it as a means to an end.
>>16166703To what ?
>>16166704NTA, but depending on the field it could just be an application thing. In my sub-field of engineering measure theory and functional analysis are super important despite them both being very "pure math."

>>16166487They use B.K. Driver's Probability Tools with Examples. Super rigorous and very "analysis forward" presentation of probability theory.I like it quite a lot as a "secondary" measure theoretic probability text after you've already gotten a good feel for things but it might not be the easiest as a first read introduction to the topic. There's a ton of exercises and the standard homework assignment list in the beginning of the book if I'm remembering correctly and it should be free through UC San Diego's website.
>>16165355Nobody I know spends more than a couple hours a day fiddling with a problem that you're making no progress onThere are many other things you can (and need to) do which you're actually capable of that you should always be able to give yourself a daily reminder that your brain isn't complete cottage cheese
>>16166129My post was because I just finished measure. I got a B+ (which was above average for my class) but I feel like I honestly didn't earn that grade even though in some sense I objectively did. I definitely learned a ton in that course but I'm not sure I'm much more confident in my proofs than I was prior because I'm just kind of a retard sometimes. It doesn't help that I'm not actually a math PhD and am instead doing a "math minor" for my EE PhD. It's kind of funny though. In some sense we have an advantage in EE because we have so much exposure to such advanced math so early, and as a result dealing with PDEs and complex analysis isn't that scary. We definitely don't focus on proofs though, and as a result I have a pretty underdeveloped skill set in that regard despite being in some sense more apt at the "computation" side of math than my math grad peers.
