How were the polls so wrong?

these polls are taken earlier than the only poll that matters (the one on election day)

also bad methodology (statistics is mathematical but it relies on a model with subjectively chosen factors to take into account)

Has it outlived its usefulness? Will we see any significant advancements besides the Higgs before it goes out of commission? And, in the end, was it worth the cost?

Nope, Higgs boson was pretty important.

It is on the nature of basic research that we do not know the end.

Hey /o, for my college science project, I made biodiesel, but now the problem is to prove that it works somehow. Any ideas? My budget is 200 dollars.

Theorem: I swear it works lol

Proof:
Suppose it doesn't work.

Therefore it works.

Is Europe superior over the US to work/study in the domain of science? Do any of you have experience with both? I'm an hs senior who's Swiss and American and I'm tryna figure out if I want to stay in Europe ...

Stay in Europe. America doesnt have any research. If they do, then its just a big competition on how shit you can go without getting your paper rejected

Portuguese engineering universities don't bet heavily on higher level maths. So, I guess I'll wait for a kinder anon

Although I am interested in learning the theory behind the method - so if anyone is patient enough, please do explain. I've read about finite volume method? Where you discretize your space and calculate values for each individual cell, but couldn't get much farther than that

Everything is deteriorating all the time. When something looks like it's not deteriorating, it's because something else is just deteriorating for it.

[eqn] \left ( \sqrt { 3x + 1 } + 2 \right ) ^2 \\ = \left ( \sqrt { 3x + 1 } + 2 \right ) \times \left ( \sqrt { 3x + 1 } + 2 \right ) [/eqn] Take the right most term [math] \sqrt { 3x + 1 } [/math] and distribute it over the both terms in the second bracket, [eqn] \left ( \sqrt { 3x + 1 } + 2 \right ) \times \left ( \sqrt { 3x + 1 } + 2 \right ) \\ = 2 \times \left ( \sqrt { 3x + 1 } \times \sqrt { 3x + 1 } + 2 \times \sqrt { 3x + 1 } \right ) [/eqn]

Simplify that then just do the same with the remaining [math] 2 [/math]

What's /sci/'s opinion on Cure-all supplements?

Do they work? Are they harmless? Whats the science behind them?
29 posts and 1 images submitted.
>>
Placebos. They're allowed to be sold with vague medical claims because it's a huge industry with lobbyists. Fake medicine is always dangerous because it confuses and demotivates people who need medicine that actually works.

They can also cause things like Hypervitaminosis because people don't realize it's possible to overdose on Vitamin A, B6, etc.
>>
If something isn't regulated, has no oversight, it's probably bogus for the most part. Without strict regulations, most of these supplements are just a waste of money, as there's no reason to have true quality control. Not to mention many supplements do not have a strong basis in peer-reviewed studies.

My mom takes so many bullshit supplements, she dumps thousands of dollars into buying bullshit "super food" pills every single year. No matter what I do, no matter what I tell her she refuses to listen to it. Fuck this new age bullshit.

how likely is it to die from excessive consumption of minerals?

It will suck if someone on my family dies from consuming these things, but I would hope that people around them will realize how these things are dangerous and should not be approached.

Is gender based on social roles that were made of initial sex diferences or is entirelly cultural?

Are you stupid or are you just pretending to be retarded?

>>8500901
serious question.

I do think gender traditional roles are biological.
>>
I don't see how gender can be totally divorced from sex the way those weirdos claim. Which they say as turn around and say long hair and wearing a dress means they're a woman and you have to respect their pronouns. They're more gender adherent than CIS are ironically.

I'm struggling in math. I just had a long conversation with an old lady who graduated at MIT with a double-major in Math and she recommended these particular books. I can at least confirm she was an old white lady because she was on chegg. First, Chegg tutors being white is pretty rare. Second, she did not want to do my PDF review for me for my final while I had Indian guys messaging me who said it would take a minimum of 12 hours time to do the review step by step. Third, she said to cover up the solutions and work on the problems till your brain hurts. Lastly, she did want to setup a time for any questions I may be struggling with if any. Did I just come across an honest lady on chegg who did not want to milk me for money? Is she making $300,000k/yr. lol. She also agreed with me that professors really do not teach anymore. Literally, I probably suck at trig because I relied on MyMathLab DL. Is this series of books or outlines /sci/ approved?

Very familiar situation like OP. I have a few wide gaps in Algebra, Geometry and Trigonometry and I was recommended Art of Problem Solving series books. Are they any good? They're pretty expensive.
