I hate the constant lecturing about morality and ethics in stem. Why should I have to have my experiments approved by some council of roasties to say that the animals and subjects are treated in some random deemed "ethical" manner. the only thing that should matter is the data is replicable in the end.

If you want navel gazing, look what happens when computer scientists and the like discuss philosophy having read nothing but O'Reilly books and some science fiction. It's always ridiculous and the discussion is always "the world is like a computer (because I don't have the grounding to talk about it in any other way)." STEMfags spend a lot of time thinking in rigidly empirical or formal ways, they benefit from a little philosophical training to contextualize what they're doing more than anyone. Write off the classics at your own peril.

>discussions about ethics are hijacked for self-serving and political purposes.
Suppose I show up to your discussion and take a negative position (if you need a concrete example, imagine the discussion is about approving an animal experiment proposed by OP, and I'm advocating rejection on grounds of animal rights). How will you decide if I deserve a seat on the opposite side of the table, or should be forcibly expelled on grounds of attempted hijacking "for self-serving and political purposes"?
I don't think the dividing line is as clear-cut as you seem to be suggesting, and this is especially consequential as it is effectively a call to censor "unconducive" viewpoints.

Is algebra not a requirement for your math degree? I would recommend both if you have any interest in applied math, but algebra is far more central so I have to recommend it if you need to pick one.
>>
>>16153660
An "introductory algebra" class that covered polynomial rings and similar things is mandatory.

The "proper" algebra class in group theory isn't mandatory for people who double major.

But I do enjoy applied math too and would love to see real world applications of linear algebra in linear optimzation.

So maybe I should drop my plans to take measure theory so I can take both these classes.

Oh, I see. OK, my recommendation in that case is linear optimization and measure theory. Extra semesters of algebra are not required for undergrad in my opinion, especially if you tend more towards applied.
>>
>>16153764
Measure theory is one of those subjects that can be taught to such absurdly varying levels of difficulty (depending on the professor). If they just keep things to measures on the real line like Royden it's not so bad but things can get pretty messy when it gets more general and when you start dealing with normed functional spaces.

Why is this happening?

serious question
I have seen a lot of gore pics of neovaginas and I've seen a lot of pics of biological male transgender women that made me believe it would be obvious, but now I'm starting to be skeptical. I know there are trans-women from countries like the Thailand or the Philippines that look very close to the real thing, and if you search on the reddit, some of the surgeries look pretty close to a real pussy: https://www.reddit.com/r/Transgender_Surgeries/top/?t=all
Is it possible you could be fucking a post-op transgender and not know it? especially someone from a country where they already look more feminine like Thailand of the Phillippines

>Do CTRL+F 'Min Jun'
Lol no. They still look completely different to the real thing. I would 100% know if I saw that in real life. Retards would get fooled by that though. They use flattering lighting and angles in these photos too. Photos also don't account for smell and feel which would DEFINITELY be off

I don't know enough about other races but surgery will never replicate the real thing for anyone.

woman I am dating has very broad shoulders, larger hands, and her waist is not that narrow, but she still has quite wide hips, and feminine face. However, I know she had nose surgery, so maybe she could've had more face surgery. Her vagina looks very good, seems more tidy than usual though, like not a lot of labia. She definitely gets wet, but not dripping wet like some girls do. And it also seems quite low down... however, I'd think with trannies it would be the opposite. It should be a bit too high, right? Since the anogenital distance is longer in men than women
I find her attractive and everything, it's just I find her a bit more bony and heavy feeling than most women I've slept with. And since I found out about the rhinoplasty and the prominence of sex reassignment surgery in her country, I got kinda skeptical
>>
>>16154114
>I don't know enough about other races but surgery will never replicate the real thing for anyone.
I would agree, but idk. maybe I'm not up to date with the latest advances in surgery...
I'm obviously not equating trans women with women, I'm just wondering if men could be fooled if they didn't look closely.
The Min Jun ones definitely look the best, but I can see that there is a scar going around the neo-labia and down from the neo-vagina to the anus. Is this also related to the penile raphe?

previous thread >>16072199

if you love stats, weird numbers and counterintutive science, this is your general. Because one of the things with statistics is that nothing ever seems to be what it tries to show you on a first glance or glimpse. Doesn't matter if you are a seasoned professional, NEET or some disgruntled grad student. All are welcome.

Some people may not like it if you try to make them do your homework, others won't care and will just help you. Let's discuss theories together, ask questions and try to meme a little about this field.

in the previous thread we discussed why Julia has promise but is not delivering. How some people still use Matlab but hate it.

So, grab your favorite statistical software, dust off your textbooks, and join me in this exciting journey through the world of /psg/ - Probability and Statistics General! Let's embark on this adventure together and unravel the mysteries of data one statistical concept at a time.

Why is RMS more valuable then stay root-mean-cube? What makes Pythagorean distance so generalizable?
>>
>>16152168
There's an easy answer and a more general answer. This guy >>16152132 is somewhat right about the early rationalization for using MSE as your error criterion before the formalization of Lp spaces later on. The simple answer is that your MMSE criterion has a simple geometric interpretation, makes for easy linear solutions via least-squares, and is a good approximation of a wide variety of real scenarios.

The more complicated answer is that the L2 is also the only Lp space whose dual is exactly the same as itself. This means if your likelihood is fully characterized by its L2 representation (as Gaussians are) then maximizing your likelihood is the same as minimizing your MSE (in the unbiased case). Thus you can solve the harder problem of minimizing the mean-square error via the easier problem of maximizing the log-likelihood (in this case).

If you were to use mean-cubed-error, you'd have a circumstance where your answer could be either positive or negative, and you may have two complex roots. It also doesn't tell you all that much if you minimize the skewness of your estimator. You could have a totally non-skewed estimator that is complete junk (e.g., a uniform random variable centered at the right place but uses none of the information in the measurements). Being un-skewed has little meaning for general performance, while being unbiased (meaning your mean error is zero) and efficient (meaning your MSE is as low as is possible) has clear meaning for performance purposes.

Ok I am going to give you some solid advice.

Number one - pivot to another field from your ridiculously theoretical bullshit.

I suggest some fluid mechanics, RF calcs or anything that require a solid foundation of math.

Learn another language, like German and then just move. If I would have taken a big degree like you and the country I lived in would not let me work. I'd just pack my bags and fuck off.

Furthermore, you are living in one of the smallest places to work for your degree in the industrial world, barred iceland. Just move. Learn French, German or Italian.

Stop looking for jobs within quantum mechanics and math, because there are no fucking jobs in that field you retard manbaby.

Quantum tunneling just comes from putting a non-infinite potential into the Schroedinger equation. And guess what, no potentials are actually infinite. Physical contact is functionally infinite because your mass of entangled particles trying to push through the extremely high relative potential of another mass of entangled particles gives . The idea that physical contact is infinitely continuous materials pushing against each other is an incorrect view of the world based on our macroscopic point of view. Tunneling isn't actually strange at all.
