Is there any clue of what causes gender dysphoria ? Is there any way to treat it ?
Im sure any parent would rather have their kid treated at a young age to feel according to their biological sex than let them be whatever and suffer in their adulthood because "there is more than 2 genders, patriarchy, blabla"
Im sure feminist wouldnt like it but thats another discussion

This entire time, feminists and people who identify as different genders are the best trolls and we have all been to autistic to notice.

>Draw a line
>On your line, place a dot. This is your point of origin, or '0'
>Next, draw a second dot on your line that is to the right of the origin.
>The distance between your two dots is the unit length, or '1'
>Mark another dot one unit length to the right of your previous dot

Congratulations, you now have a number line.
I graduated with a subpar GPA of like a 2.95. Worked several years. Decided I wanted to go to a PhD program and enrolled as a postbac student at a top university that just happens to be in my state and made a 99 in my first course there and am on track to make another A in my second course. I'm sitting in a few other courses and doing the work there and would be a top student in those courses as well.
Anyone else have similar turn around stories? For whatever reason things are really clicking for me. Pretty much every class I'm in a developed a rep of being a top student. This by no means how I was when I was doing my undergrad degree.

Good argument. Infinite objects are hard to observe but the more we can observe that system the closer we get to pi.

>Sources of knowledge
Sciences that use deduction and induction as their methods do not generate new knowledge, they just study stuff that is alredy there.
Mathematicians didnt create any new knowledge when they first realized 2+2 was 4. 2+2 was 4 even before anyone noticed because it logically derives from the initial axioms.
>Thirdly, Peirce argued that abduction is the logical inference by which new knowledge could be obtained: \Abduction consists in studying the facts and devising a theory to explain them. Its only justi cation is that if we are ever to understand things at all, it must be in that way.
So sciences who produce new knowledge are those who use abduction like philosophy.

Why does /sci/ refuse to acknowledge the huge disparity in university quality? You get topics filled with people talking about their grades in Calc 1 and Calc 2 etc. You may as well talk about how long pieces of string are. Places like MIT do Calc 1 to 3 in two courses any way. And still have more content. And Caltech does proofs etc on day one. And that's just the disparity in two maths courses. Now imagine four times that difference every year because there are 8 courses, multiplied by four for every year of the degree, multiplied by being surrounded by smarter people rather than the dumb normies who got shit school grades.
Also another way you can tell that /sci/ goes to bad unis is when they boast "99 % of my CS101: Java Syntax class failed." How the fuck is this a boast? The shitter universities have higher drop out rates (a few exceptions, when they take many people but weed them out, but this is rare and mainly very prestigious nationalised institutions). Hard working students almost always pass. If a Harvard guy goes up to me and says "99 % of people passed CS101" I'm not going to see Harvard as shit.
When I once posted a problem from the first year Oxford maths course on here as a way to troll people at worse universities, I got tonnes of abuse.
Also I'm not an Ivy league guy. I'm a guy who went to a uni ranked 100 - 150 in the world and I am as butthurt as anyone can get. My anus is redder than a cherry dipped in blood. Don't think I'm trolling. Also there are very few exceptions to the stuff I say: I mainly think of Germany, or other mainland Euro countries (not France), where I think there is more equality due to government intervention or something (or maybe we just never hear about them).
>inb4 only grad school matters
Yeah, sure, 4 years of the difference in quality I talked about contributes zero difference to grad school performance...

It's true that the top universities sometimes cover more, but when it comes down to it, a degree in (speciality) engineering is a degree in engineering. With the exception of possibly the first employer, most aren't going to put much stock in your schooling, but instead your employment record, because all fresh engineering grads only know the basics, no matter where they came from.
And for the record, MIT calc sequence doesn't cover more than most schools (it actually covers less than a great many), because their calc courses are meant to function as a quick review (everyone accepted into MIT has taken at least calc 1). I followed Ocw when I was taking my calc sequence and we covered a lot more (probably because it was 3 semesters, and not 2). It's my belief that the power of top institutions lies in the prestige/ability of their professors, not the material they're teaching. Right now one of my physics professors can barely speak English, talks extremely low because he's unsure of himself. I imagine that doesn't happen at MIT

Curious to see what that problem was and how did you get it from. I'm also butthurt that I go to a noname yuropoor university (especially considering that I had a real chance to study dans la France), but I guess if you show initiative, motivation and get up to par with Cambridge/Oxford/whatever students' syllabus on your free time, you can still get pretty damn far.

Sup. Can any chemfags check my math?
Say I have a standard 4-stroke single cylinder internal combustion engine with 1" bore x 0.8" stroke. The head has no recess or special combustion chamber geometry. The valves seat flat to the surface of the head, so the top of the cylinder is effectively just a flat surface, 0.125" above the top of the piston at TDC. Naturally aspirated, no port tuning.
On the intake stroke, it draws in a stoichiometrically perfect amount of ethanol and air. How much of that is ethanol? How much is oxygen?
C2H6O + 3(O2 + 3.76N2) = 3H2O + 2CO2 + 11.28N2
I got 0.01029L of displacement = 4.59E-4 mol. (4.59E-4)/4 = 1.15E-4 moles of ethanol and (1.15E-4 * 3) = 3.45E-4 moles of air. (3.45E-4)/4.76 = 7.24E-5 moles of O2 and (7.24E-5 * 3.76) = 2.72E-4 moles of N2. That's the input.
4.59E-4 * (16.28/4) = 0.00187 moles = 0.0419L after the reaction.
Is any of that right? It's been a while since I took chemistry.
On the compression stroke, I believe finding the pressure at TDC is just (P1V1)=(P2V2) right?
So (101325Pa * 0.01029L) = (P * 0.00161L) -> P = 647598Pa before combustion.
On the power stroke, when the compressed air/ethanol mixture is ignited, how much does the pressure increase? How long does it take for the flame to burn all of the air/ethanol mixture? How much energy is released? Is the force exerted on the piston F=PressureĆArea?

You should post it with a picture of cartoon girl on front of blackboard with your problem written on it and add "you should be able to solve this" so we wouldn't notice it's your homework

>On the intake stroke, it draws in a stoichiometrically perfect amount of ethanol and air. How much of that is ethanol? How much is oxygen?
Google the ideal azeotrope for ethanol and oxygen in the gaseous phase. Remember that 70% of the air is nitrogen or what ever
Any graduate students here?
I just started my first semester in applied mathematics and am already feeling the pressure. I'm only taking 3 classes, one of which is the second semester of Undergraduate level real analysis using Rudin, but this real analysis class is sorta kicking my ass. Am I supposed to be spending all my free time on problem sets?
Does anyone have any advice about learning upper-level maths or any advice about graduate school in general?
Also should how soon should I start worrying about research?
>>8624651
>upper level math
>undergrad course using baby Rudin
Pick one.
>>8624673
Yeah I am taking a remedial class but it's good that I'm doing so because the grad level sequence would probably kick my ass even more. Is the jump in difficulty from rudin to graduate level texts really high? Will I ever get used to doing extremely technical proofs assuming I'm only barely slightly above average in intelligence?
>>8624697
Grad class content isn't that much different, at least early on with upper division undergrad. The difference is that the content is convered more quickly and the profs don't hold your hand through the development of the content. That puts more work on you, which is why it seems harder. I took a grad level class this semester because I met the pre reqs. But the review material was from courses I hadn't taken so I dropped it for something else. I definitely could have made it through but it would have been a lot more work than I'm willing to put in.
