Why are people afraid of cancer when it will probably go from a terminal condition to a chronic ailment within the next few years?
>lol why are people afraid of dying from horrible disease!?
fucking moron

and why would that be?

This.
The cure for cancer is a meme. You can never cure it. At most we will develop highly effective treatments, but they won't be 100% and they won't be the end of cancer.

Alright /sci/ Chemist needing some help here, trying to make up some crystals due to the cool orange look. Something has gone wrong obviously, I think I know what it is but if anyone has any other ideas they would be appreciated.
I melted a Stainless Steel spoon in 1 mol/liter HCl. This produced a mixture of FeOH, CrOH and NiOH, evidenced by a green colour of the Cr3+ ions. After this I added Sodium Carbonate to precipitate the Chromium Hydroxide then filtered, the dried slurry was then but in a container and I added concentrated H2O2 and then filtered again producing...

trichloro chromium III is supposedly green as a hydrate too, and certainly water stable. How does the carbonate work?
>>7800704
Couldn't you try adding some silver nitrate to a sample portion see if any silver chromate falls out of solution?
I believe upon the addition of sodium carbonate you also precipitated out Iron(II) carbonate,making with the other salts.
What's the general consensus about this here?
Pardon me if it has been asked before.
I'm in high school and want to excel in mathematics. Wanted to know the opinion of all you /sci/entists.
Thanks.

That picture is retarded as fuck. First of all it won't make you a "math monk" but only puts you on the level of a first semester undergrad. Secondly it is impossible to study PDE before analysis.
>>7800516
>first semester undergrad has learned all of calc, linear algebra, set theory, mathematical logic, combinatorics, graph theory, number theory, numerical analysis, differential geometry, probability, PDEs, abstract algebra, topology, and analysis
am i retarded? is this normal somewhere? are there high schools teaching PDEs, abstract algebra, analysis, and topology? are there high schools teaching math quickly and efficiently enough that you could learn all this going into you...

Short answer: no, no high school teaches these things
However I did take most of those classes in high school, but that was at a local college, and was highly unusual.
The pic in OP outlines what an undergrad should know upon graduation, more or less
who else /waiting for graduate admissions/ here

Is it scientifically possible to measure the intensity of pain?
If it is, then what is the objectively most painful form of torture?
>>7800409

Browsing /sci/
>>7800409
It's possible with psychophysical methods, but good luck getting IRB to approve the study.

Yes: here you go, no brain scanners or other plecebo bullshit that impresses plebs required.
Any machine learning / stats people here?
I need to fit a curve by manipulating 3 variables. The process that calculates my guesses is expensive to run (~45 minutes) so I would like to minimize my number of guesses. Are there some statistical methods that can give the optimal numbers to try?

yep

And they are?

GR is a meme, you shouldn't fall for the GR troll so easily, it's not really an established theory.

Please don't lump me in with the physicists. No ne respects them.
Anyways, let me play devils advocate and say that they use the word 'fall' only so that retards like you can understand what is happening.
Picture a plain surface and a point moving across it. Simple, right?
Now picture a slightly curved surface that you are looking at from the top. If the surface is curved down you would see a point moving down with the surface. If the...

Alright, /sci/.
I would go to /adv/ but I don't think the people that lurk there have the information I'm seeking.
I decided about 2 years ago that my goal in life is to participate in serving the world by lending my time to renewable energies. Solar, Wind, Geothermal, Tidal, what have you.
I think this is the best way to improve the world as it is and even if, somehow, renewables are -not- the future, I still want to work in the energy sector, the wee details of how energy operates and is harnessed is endlessly fascinating to me.

Call up/email companies in the related field and ask them yourself.

Why do you think renewable energy will improve the world?
>>7798658
I see it as more efficient. Yea sure, we could go into the whole save the manatees environmentalist side of it, and pollution is a real preventable thing but for me it's mostly an interest in bettering our proficiency as a civilization
Is Computer Engineering a meme degree?
I'm currently a first year CE student and my colleagues from the EE course always joke
about how CE is EE's retarded cousin.

>Is Computer Engineering a meme degree?
yes
>ME over EE
ebin
its pretty torturous and sucks the life out of you. it's great if you're a smart anti-social loner with no social life.
>>7797480
Why ME over EE, about to go into uni and picking my majors, and I think I will enjoy ME.
Friendly reminder that he was a talentless hack and a (SPOILERS) Jew who ripped off the work of actual physicists and took credit for it.
And you still probably believe he "discovered" relativity. Stay addicted to the jewish "science" good goyim :^)

Are there any ways to train your brain to work faster? For instance, if you were to practice doing mental arithmetics, seems like all that practice will do for you is memorizing results so you can later take shortcuts when working with them. Which is helpful for that specific purpose, but isn't actually increasing your brain's processing speed.
Is memorizing shortcuts for the specific activity you want to become faster at really all that you can do, or is there something else?
>>7803094
The brain doesn't work like a microprocessor or hardware computer system, it doesn't really have a definable processing speed or any method of increasing it. The brain is a greasy sack of chemicals with some meat-wires throughout and it's immensely less understandable than a computer.
There are drugs that modify brain chemistry, but never permanently and you develop tolerances.
So in short, no.
>>7803094
For increasing your raw intelligence, all of the shit you see claiming to do that is bogus. I've heard of Dual N back tests doing so, but the improvement fades after you quit doing them.
You get smarter/better at problem solving by doing really hard problems a lot. There's not shortcut. There's no game. Honestly, go pick up your text book, look at all the problems you weren't able to solve, and begin solving them.
If you want to become better at mental mathematics, look up Arthur...

Why are there more male female-foot fetishists than male female-hand fetishists?
Background: Someone told me that the seeking of female fertility markers (such as symmetrical features, ample breasts, lustrous hair) was the reason men find feet attractive.
>>7802077
You are mentally sick.
>>7802079
Please n-no
my perversion must be justified
The reason men find feet attractive is due to the location in the brain that controls our feet is right next to the portion of the brain that's responsible for our genitals, so the wires get crossed often. Men have higher sex drives, so that's the reason foot fetishes are more common in men (women would just get a pedicure if they wanted to feel good)
So, this is american science?
