Explain to me how transgenderism isn't a mental illness?
I have yet to see how they aren't just a bunch of psychotic faggots.
we don't discuss lgbt garbage outside of /lgbt/

It's certainly a mental illness. If you doubt this go to any hospital or psychiatric centre and tell them "I'm thinking of mutilating myself, I really want to cut my penis off" and see what happens. So why do we allow it to happen? Well partly because society has become more tolerant but also because, as it turns out, transitioning is the only way to reduce the daily anxiety that people with these delusions suffer from.

Politicization of clinical psychology, an already spurious discipline.
I'm starting graduate school in pure math this fall. Is this book any good? Also, how do I start an academic book library as a cheapass poor grad student.

Space exists, so it has to be something, it has to consist of something. Like, shouldn't space be made of 'units of space' that can, at least theoretically, be observed and measured? Mass has an effect on space, in other words space itself can be affected which would also mean it can be manipulated.
What is space? I know some of you guys actually know shit, help me out.
>>8006716
As far as physics goes, "space" is just a placeholder for "area".
https://en.wikipedia.org/wiki/Space
It really is just a set of coords to represent a location. You don't actually affect space, you affect the objects in it. You can represent that as using an alternate set of coords to show that "space" has been affected.
>>8006716
Mass has an effect on fields which permeate space, but it doesn't have an effect on space itself. Space is just a place that holds all these things.
Hi, I'm a mexican Mechatronics engineer, who always wanted to study something aerospace related. Due to family problems, I couldn't.
Now, I'm looking for a Ms.C. which can give the skills, to join this wonderful indsutry.
My most inmediate goal is to join a proper Masters program for this purpose, that's why I come today to you, /sci/chos to give me a proper guidance or recommendation.
Previosuly I asked about the topic, saying it pigeonholed me chossing this.
My main questions are:

Bro, I'm a Mech E. from Mexico and I'm wondering the exact same thing.
Last year there was a program by CONACYT to do you masters in the UK (on something related to astronautical/aerospace engineering), I'd recommend searching for something similar.
Narrowing the list, I highlight the actual univiersities who offer an MsC Aero program, supported by CONACYT
UK:
>Cranfield
>Bristol
>Sheffield
>Manchester
>Southhampton
>Leeds
USA
>Purdue
>USC (Viterbi)
Japan
>University of Tokyo
Spain

Hi , I want to read about alqumia and wanted to know if I can pass books on the subject (Obviously that can be downloaded from any page )
Thank you!

Your native language is spanish?
Yes, I not speak in english :(

>worried about the overpopulation crisis and man's damage to the environment
>pump more money into cancer, diabetes, Alzheimer's, obesity and mental health research to save precious lives
Why are scientists such hypocrites?
because people working for a better society get cancer, alzheimers and mental health issues as well
>>8004794
But what about the overpopulation crisis and man's damage to the environment?
>>8004791
I don't give a shit about your infantile "ethics". I just wanna get rich.
If I were to count for an infinite amount of time, what number could I count up to?
depends on how you are counting
>>8003757
One number per second, for simplicity.
>>8003758
Then you could count to one, for sure. Possibly even two.
/sci/, I very legitimately don't understand the Monty Hall problem. As a matter of fact, I think I don't understand probability in general.
So for the newfags who don't know the Monty Hall problem: https://en.wikipedia.org/wiki/Monty_Hall_problem
But anyway, my beef with it is this: When you are asked whether or not to switch doors or stay with your choice, isn't that a fundamentally different probability set than when you were first asked to choose?
I get that the idea is when you first choose, you only have a 1/3 chance of getting it...

there's three possible outcomes: {goat1, goat2, car}
if you picked a goat (2/3) then switching will get you a car whereas if you picked the car (1/3) switching will get you a goat.
So in 2/3 of possibilities switching will get you a car.
Actually, here's another beef I have with probability. Supposedly, with a hypothetically perfectly random coin, every time you flip the coin, there's a 1/2 chance of heads and a 1/2 chance of tails. EVERY time you flip the coin, regardless of what you've flipped previously.
And yet, to calculate the chance of flipping 3 heads in a row, one uses (1/2)*(1/2)*(1/2), which is 1/8. So on the first flip, there's a 1/2 chance of getting heads, then, on the second flip - since the chance of getting two heads in a row is 1/4, surely the chance of getting tails...

You can easily google this to get your answer.
The entire point to this thought experiment is that the person that opens a door after your initial choice knows what is behind each door. Given that he knows what is behind each door and won't open the only door you don't want to select, even a grade schooler can draw a simple diagram for each case and conclude that you're better off switching doors. If the person opening a door for you doesn't know what is behind any of the doors, it's...

As an undergrad doing research, how do I get rid of impostor syndrome? I know what I'm doing, but I feel like I shouldn't know what I'm doing. Does that make sense?
>>8005976
thats the opposite of imposter syndrome
I had never heard of this before. I looked it up and holy shit it's me in a nutshell.
>Despite external evidence of their competence, those exhibiting the syndrome remain convinced that they are frauds and do not deserve the success they have achieved. Proof of success is dismissed as luck, timing, or as a result of deceiving others into thinking they are more intelligent and competent than they believe themselves to be.
I don't mind though because it gives me incentive to not become complacent.
>>8005976
Short answer is that you don't ever really get rid of it. I'm a post-doc and still feel like I really have no business doing what I'm doing. At some point it jus kind of gets mixed in with a misplaced sense of arrogance where you feel some strange satisfaction when your peers fail at things that you succeed at, yet you can never really be happy with your own success because you feel that it is unwarranted and will get taken away at any moment.
I'm teaching Algebra I next week to the "troubled kids." How fucked am I? Any tips for keeping or getting their attention?
Balancing an equation is like balancing your life homes.
Lifes is like full of mysteries, and like, sometimes you have to solve for x.
But you gotta learn the correct order to do things in homes.
>>8005974
Use a graphing first approach. Have each member of the class come up and plot one point on the board until a line begins to form, conveying the idea that a line is just an infinite number of points, and that algebra is just about relations.
troubled kids as in troublemakers or slow people ?
Someone here uses GNU Octave? What can you say about it?
runs all my cfd code just as good as matlab
>>8005862
its not as good as matlab.
Is there any way to "show" octave code in a natural format i.e what TeX format does.

Where did I fuck up?
sinx + cosx = -sqrt(2)
sin^2x + 2sinxcosx + cos^2x = 2
2sinxcosx = 1
sin2x = 1
2x = sin^-1(1)
2x = 90
x = 45
2x = (90 +360k)
x = 45 + 180k
^but this isn't always correct either, how do i distinguish when k is nondivisible by 2?
>>8007940
it's a bit tricky since your original equation was basically for x from 0 to 360, but when you take 2x= sin^{-1}(1) you only get answers for 2x between 0 and 360 even though the number you want is more than that. i.e.
2x=sin^{-1}(1) implies 2x=90 OR 2x=450
and so x= 45 or x=225 but only the second one satisfies the equation you started with
>>8007951
when you square an equality you have done a non-reversible step which can add additional solutions, since a^2=b^2 does not imply a=b. so you always have to make sure when you do non-reversible steps that your final solutions after work with what you started with
I'll start and make it fancy in the form of a haiku.

I was so upset with an ongoing abuse of statistics in the media, that I came up with this initiative - www.statsguard.com . Whenever you see any misuse of statistics in the media, please report it through my website, I would really appreciate that :)
