and once you're done, you've basically learned nothing. Now compare that with soviet/russian authors like Landau/Lifshitz, Shilov, Fichtenholz, Arnold, Zorich, Gorodentsev, Piskunov, etc. All of their books are extremely concise, waste no space, make sure to include EVERYTHING, have hard as fuck but pedagogically valuable exercises, and you will be a fucking god in whatever field you choose after going through one of these books carefully.

Have you been doing your networking? Share stories of your expenses-covered travels.
I have made it with a woman, sort of, again. Last night, I treated myself to full nude VIP. Cover was $35, and dances were $30 each. A bespectacled Latina named Jessica approached me and led me by the hand to the VIP area upstairs.
Afterwards, back at the motel, I told a guy at the desk, "Hey, uh, cousin. I was wrong about this town. That was awesome." With a big stupid grin, I showed him the VIP wristband and the defense lawyer contact wristband.
In the morning, I attended the last of the geometry talks and asked some of its most competent questions. I joked with several of the younger men mathematicians I had become familiar with: You may have noticed that I am bundled tightly in my Weizmann Institute jacket with the collar sealed around my neck, when yesterday I was complaining about being hot. When we are in less polite company, ask me why that is.
In the less formal company outside, I explained: It's because my shirt smells as if - as if, mind you - I visited one of those gentlemen's clubs. This is not as wholesome a town as the one where I attended the representation theory conference last weekend, and I would never do that in the latter, though you shouldn't take that to imply something. I'm also heating the volatile compounds so that I can release them in the car and savor them on the drive home.
I forgot to mention to them that I could have bought the perfume for myself at a Victoria's Secret. In fact, I think it actually is from there, a perfume with a pear fragrance I remember from years ago.
We of the conference said our goodbyes. As I pulled the car out of the campus roundabout, I noticed a residue on the front of my shorts that I'm fairly certain did not come from me. When I get home, I shall thoroughly sun dry it to purify the rear of any traces of stuff from other dudes without washing Jessica's souvenir from the front, and I shall not wear them anymore.

Background: Symptoms of primary HIV infection, including fever, rash, and headache, are nonspecific and are often described as flu-like. COVID-19 vaccination side effects, such as fever, which occur in up to 10% of people following COVID-19 vaccination, can make the diagnosis of acute HIV infection even more challenging.
Case presentation: A 26-year-old man presented with fever and headache following COVID-19 vaccination. The symptoms were initially thought to be vaccine side effects. A diagnostic workup was conducted due to persisting fever and headache > 72 h following vaccination, and he was diagnosed with Fiebig stage II acute HIV infection, 3 weeks after having unprotected anal intercourse with another man.
Conclusion: Thorough anamnesis is key to estimating the individual risk of primary HIV infection, in patients presenting with flu-like symptoms. Early diagnosis and initiation of antiretroviral therapy is associated with better prognosis and limits transmission of the disease.

>Last September, astronomers in Japan detected a series of objects in the Kuiper Belt – described by the BBC as a "doughnut shaped region of icy bodies" beyond the orbit of Neptune – that had unusually warped orbits around the Sun. Researchers Michael Brown and Konstantin Batygin, from the California Institute of Technology (Caltech) in Pasadena, speculated that only a massive planet's gravitational pull could explain these "orbital anomalies", said Live Science.
>Then in February, scientists narrowed down the "likely hiding" place of the "elusive" planet after they "whittled away" 78% of the "hypothetical world's suspected orbital pathway", said Philip Plait in Scientific American.

Will Vyvanse still work if the powder is left out in the open air for a long period of time?
If one were to open a capsule of Vyvanse, pour the powder out, and let it rest on a plate in their room, would the Vyvanse become partially inactive? Would someone still be able to feel the effects if they consumed the powder, say, the next day? I have an exam tomorrow, I had split a pill the other day, and was planning to take the other half today. Took it, haven't felt anything. Need help pls.

The existence of transgenderism as an incurable medical condition which can best be treated through transition has been extensively scientifically proven. Brain structure and whatnot. It’s no more “up for debate” than climate change is.
Whether trannies are weird, gross, degenerates is however debatable. Whether it is better to treat them with hormones or to euthanise them still hasn’t been determined.
An important distinction. Facts don’t care about your feelings. The fact that transgenderism is real is objective true, and is not changed by anyone’s feelings that trannies are freaks. However, this fact does not mean one cannot have different ideas on what should be done about trannies.

Medical science isnt real. Its demons all the way down. Yk mental illnesses connect you to other realms:
Autism: spams you with information from all realms. Sometimes makes brain better at handling information.
OCD: serves your brain things that could have happened (related dimension). The brain wrongfully thinks this will happen if you dont do something.
Shizophrenia: positive: false truths recieved from different dimensions negative: energy sucked into those dimensions
Bipolar: alternation between recieving energy from place 7 and getting it taken away from place 4. more on places on /x/ soon.
So anyway there are 2 types of "medication":
T1: every demon gets in and starves after a certain amount of time
T2: the first demon you eat while not having that demon-species in you gets in, the others get tpd back. The demon eats the now empty "meds" (T2s contain food for the journey) if youre still trying to eat "meds" and if you stop he starves.
There are multiple demon types (that each have many species!) that belong in the "meds" catagory:
Anti psychotics: (T2)
The demon tries to block the connection using magic which has many side effects
Ssris: (T1)
The demons take the hit of the connection directly. Their very resistant but will eventually succumb to their wounds, leaving a numbing corpse. If you stop taking it theirs not enough to block the thing so they get thrown around causing a electro shock sensation.
Anti depressants: (t1)
Anti deprassants try to get some from place 7, but it usually corrupts along the way.
You may wonder why nsar tablets are so big
Well thats because theyre so powerful. Mg is acctually a hoax just size matters.
Nsar: (t2)
This one is very powerful as he records ur state in being, then tries to filter out the pain and then he plays it. Since hes a demon he isnt to careful on the filter part. He needs very much food.
