Is it meant to break someone mentally? Granted, I don't come from an engineering background, but what the fuck is this?
>>8920395
It's not so much that the work is extremely difficult (it is, trust me) but it's the VOLUME of the work.
They literally go through 3/4 chapters in two weeks, put the hardest and most fucked up problems of those chapters on the exams and then shrug when the averages are between 40-60. Not only that, but the projects are always, ALWAYS, intense, takes 500+ lines of code and it's just a fucking nightmare.
Everything about this degree is nightmarish. I'm partially regretful that I ever decided to switch out into PhD. Everything is a struggling nightmare. I've literally gotten at least one C in every single semester I've been in engineering grad school, with me praying to God/Allah/Buddha/Satan that I get an average of A/B to save me from being under a 3.0 in my other classes.
Just what the fuck is this? Is it meant to just break down students?
For the record, I attend a top 15 Math program / top 20 engineering grad school
Yea, I guess this isn't a blog after all.
Shouldn't have come looking to talk about my problems, anyway. It's 4chan after all.
You talking undergrad? I only do essential work during the term (projects) and just cram a few days before exams, and I cruise by with an 80 average in ME. I have tons of free time.

>Multiplication is repeated addition
>2*5 is the same as adding together two groups of five objects
>5*-2 is adding together five groups of -2 objects
but when we get to -5*-2 we're adding together negative five groups of negative two.
How can you add together negative five groups of something?
I can understand having 5 groups of -2 but having -2 groups of 5 or -5 groups of -2 makes no sense to me.
Can anyone explain to me what it means to have negative groups of something?
>>8919378
>multiplication is repeated adding
>2.3692 groups of 2.59285
>>8919488
That makes perfect sense.
You can have 2 groups of a number then take a fraction of the number n, thus have 2.n groups of a number
2.5 * 10 = 10 +10 + 5
>>8919378
I think what you are really asking is "why when you multiply two negative numbers together do you get a positive number?".
It's a natural result of the abstract algebra structure known as a "field" that follows from its axioms.

I don't feel like writing up the LaTeX, but this guy walks you through the proof.

Is there anything like "The Feynman Lectures on Physics" but for math. I want to learn math but with full understanding of the terms commonly used. Hope you can help anons.
sadly mathematicians are autistic and none have as much charisma as feynman, so no thing will ever exist

Because in your mind, you know in the future you could just have a machine do it
>>8919852
Exactly. In the future, lab chemists will be replaced with machines. But who designs how these machines work? Chemical Engineers, of course! Just goes to show that all of STEM except for the E is a meme.
Why is /sci/ the most intellectually dishonest board?

>as charitable as possible
sorry if you dont like cold hard facts and prefer them sugarcoated because your mother didnt love you but it's not my fucking problem.
you want an specific answer ask specific people snowflekin. dont go searching on 4chan for your subjective answer and cry when the earth is actually round
>>8917968
I'd tell you, but the fact you had to ask shows that you're too much of a brainlet to ever understand.
>>8917980
Being charitable is not about being nice, it's about making sure you understand your opponents argument as well and as honestly as possible, so that you're not attacking a strawman they never meant.

Has anyone else noticed that Engineers tend to me economically very rightwing while Mathmaticians and Physicists tend to be economically very leftwing?
I noticed it quite a lot in my department. But also in famous people. Example Ted Kaczynski is an extreme example and you literally cannot fail by picking a random engineer. They will 95% of the time be a Republican libertarian or even some Rothbardian anarchocapitalist type.
I guess it makes sense. One side is funded by the public to do research for the public good while the other is just a professional rendering a service for money. Mathematicians have potential to earn much more but forgo that path of life to do research instead.
Anyway, I'm mostly wondering whether you notice this pattern in your departments as well.
Also anything (*Applied), doesn't count. Their life is more like that of an engineer.
Yes. Pure math student myself. It is very evident in my department. What's the point of this thread, anyway?
>>8916966
Just wondering whether my dept. is an outlier.
>>8916944
Makes sense
When did you realize that science is the most unironically cucked career option available.
They promote Einstein to make you think that maybe someday you could contribute to society in a way that would make people like you.
All the benefits of science are given to the people who AREN'T doing science. New technology, AIDs treatment, consumer products etc.
A farmer gets to workout doors. A teacher gets to watch their students grow. Doctors get to see how much they make a difference to their patients.
Every job has appeals to them except science. If you slave away at equations enough you might benefit people who you don't know and who will never thank you.
How the fuck do people think that solving equations is the best thing in the world for them. You can never enjoy life as a scientist. Your always thinking about the future. You don't get to live in them moment.
All the people who don't do science get to live in the moment, enjoy life, let the millions of science-slaves slowly change and build the world around them.
Meanwhile you'll be solving the same problem for years and once your done with it; your only reward will be more problems.
I only wish I had known sooner so I wouldn't be in debt.
>don't do science goy!!! not worth it!!!
>>8916426
>make you think that maybe someday you could contribute to society in a way that would make people like you.
it's "contribute to society in a way that will benefit it"
you depressed selfish piece of shit
most of those people also do you something for you day in day out, and giving them better toold for it benefits you as well
>>8916432
>giving them better toold for it benefits you as well
Most likely won't make a difference to you while others get benefits.
If you think that's a good enough reason to stare at equations all day kindly reconsider.
Hey guys.
So, I'm pretty new to this thread, never posted here before. But since you guys like science and stuff, i'd like to hear what you guys think about this "multiple gender" thing thats been really trending lately.
Like, you are either born a male or a female, there is no extra gender.
Just because you are born a man, feel like you are a woman inside, and you are a-sexual, it doesnt mean that you need a gender just for that feeling.
I mean, I'm a straight male, and I like to eat every once in a while. Does the fact that I eat often, the fact that I am a man and the fact that I eat alot make me compatible for another gender?
NO.
Personally, I think this "multiple gender" thing is just this one thing that a few people thought of to get some attention. At the time this caught attention, noone did this before, so every TV channel wanted to report it.
Then all the fucking mongos from America came, and thought;
"Hey! My mother and father never cared for me, and I was raised by a fucking cardboard figure under the pier on the beach! If I identify myself as a lesbian mixmaster, I can make the news, and my parents will know what they missed out on! HAHAHA!"
Or, something like that.
But anyways, what is your opinion on this?
Multiple genders don't exist. There is only one gender: the human gender.
oh, you weren't here during the aftermath of that Bill Nye video. "spectrums" became this huge meme for like a couple weeks.
Of course you're right, but there's no sense in rationally arguing about it, no one who defends the opposing argument knows jack shit about biology, or if they do then they're lying either for money or some other motive.
Most of the people advocating this idea are trying to assert that 'gender' isn't the same as 'biological sex', and is related to emotional identity or something. But then of course we'd be left to wonder what exactly 'gender' is in the first place.
My own opinion is that this started off as an internet subculture like furries and otherkins, pretty much harmless, but then due to sparking the public bathroom issue it got adopted by tumblerfags and blown up into a social movement, and now Hollywood and the mainstream media have taken it under their wing as part of their endless crusade against morality.
Bill Nye is literally the closest thing we have to proof that there are multiple genders. Just him saying it. Other than that, biology is pretty clear.
Alright, give it your best shot to justify this fucking bullshit.

So biological immortality will probably be invented within the next 200 years. What do you think the chances of being alive when it happens are?
>>8913589
50%
either you'll be alive or you won't
>>8913596
Oh yeah I forgot thats how quantum mechanics answers all questions. Thanks anon.
>>8913589
0%. We'll be the last generation to live normal lifespans, the next will live mildly prolonged ones, then the next substantially and then their offspring will be designed to be immortal.

hey /sci/, I know this contains a video game reference but /v/ is in a tizzy over which scenario is correct, what do you think?
>>8911770
A is correct, there is no momentum transfer to the cube.
>>8911783
that's correct but people keep arguing that "relativity" makes b correct
>>8911787
how would that even work?
