It increases intelligence, but so does any complex problem. Nothing special, just popular.

I'm aware of the fallacy, although the question still remains, do you think it can improve intelligence say more than dual n-back or bilingualism?

Is it normal to get penalized for not showing work for the quadratic equation and the auxiliary equation? Nobody knew we were suppose to show the work. At least two other people in a class of 10-15 people got heavily penalized for not showing the same. Is my college a meme?
>>8228070
No but your teacher is a dick
>>8228070
It is simple:
Step 1) Read instructions
Step 2) Show your work
Step 3) ???
Step 4) Profit
Showing your work is beneficial for two reasons: partial credit and telling your grader that you know what the hell diff. eqs. are. Otherwise how do you prove that you didn't cheat?
If I got a complaint like OP's, I would tell that student to retake the exam in my office while I watch him.
kill yourself my man.

WHY are there laws of nature?
>>8225645
Because our universe - imagine it as multiple geometrical shapes with different colors each - going trough each other - our universe is something random there - but if the triangle would be just a little down the universe wouldn't have enough dark energy, nor no law of gravity at all ... and the big bang - activated every single combination and we are one of the boom.
>>8225645
What would it be like if there weren't laws of nature?
>>8225645
Because quantum fluctuations.
What is consciousness?
In each 7 years all atoms of our bodies changes completely. There is not a single atom in commom in your body today as in 7 years ago. So are you a different person? The kid died? If consciousness is just chemical reactions, how can it be constant if the atoms were changed?
If something clones every single atom of you and paste it by your side, the clone will be you? Will you feel his existance, too? Both of "you" will feel each other existance?

Of course this is pretty much proven due to experimental verifications of Quantum Entanglement.

Is proving 1+1=2 the hardest problem in mathematics?
>>8219896
troll?
Ok, the proof starts from the Peano Postulates, which define the natural numbers N.
N is the smallest set satisfying these postulates:
P1. 1 is in N.
P2. If x is in N, then its "successor" x' is in N.
P3. There is no x such that x' = 1.
P4. If x isn't 1, then there is a y in N such that y' = x.
P5. If S is a subset of N, 1 is in S, and the implication (x in S => x' in S) holds, then S = N.
Then you have to define addition recursively...
Def: Let a and b be in N. If b = 1, then define a + b = a' (using P1 and P2).
If b isn't 1, then let c' = b, with c in N (using P4), and define a + b = (a + c)'.
Then you have to define 2:
Def: 2 = 1' 2 is in N by P1, P2, and the definition of 2.
Theorem: 1 + 1 = 2 Proof: Use the first part of the definition of + with a = b = 1.
Then 1 + 1 = 1' = 2 Q.E.D.
Note: There is an alternate formulation of the Peano Postulates which replaces 1 with 0 in P1, P3, P4, and P5.
Then you have to change the definition of addition to this:
Def: Let a and b be in N. If b = 0, then define a + b = a.
If b isn't 0, then let c' = b, with c in N, and define a + b = (a + c)'.
You also have to define 1 = 0', and 2 = 1'.
Then the proof of the Theorem above is a little different:
Proof: Use the second part of the definition of + first: 1 + 1 = (1 + 0)'
Now use the first part of the definition of + on the sum in parentheses: 1 + 1 = (1)' = 1' = 2 Q.E.D.

Interesting math probleem thread
>>8224296
A deck of 52 playing cards is shuffled and placed facedown on the table. Then one, at a time , the cards are dealt face up from the top. If you were asked to bet in advance on the distance from the top of the first black ace to be dealt, what position (first, second, third, ...) would you pick so that if the game were repeated many times, you would maximize your chance in the long run of guessing correctly?
>>8224317
First position?
@@@@possible spolier@@@@
To win the game you have to guess the right position of a black ace and the other ace must come after it.
The odds for one to guess the right position of any black ace is not influence by the position you pick, it will always be 1/26, but the chances that the other black ace comes after your bet is maximised when you bet the first position (it's 100% in this case. If you were to pick the 52. Position, then the chances you'd Winn would be 0). So I'd say the answer is 1.

I found this paper that studied the effect of an ADHD drug on the brain activity of 'normal' people:
http://wordpress.tobiasdonner.net/wp-content/uploads/2016/07/vanDenBrinkJN2016.pdf
Some highlights:
>We pharmacologically increased synaptic catecholamine levels and measured the resulting changes in intrinsic fMRI functional connectivity.
>atomoxetine reduced the strength of connectivity globally
>atomoxetine reduced the number of strongly correlated brain regions, as well as the extent to which correlated brain regions formed local functional ensembles
The paper is way more complicated then I can understand, so if anyone could have a look at it and tell me what it actually means that would be great. I take ADHD meds regularly and don't want it fucking with my brain correlations and connections.

Of course. Why do you think they give them to people, to "heal" them? Not at all. That doesn't make money.

Rest in peace, hyperloop.
Other than discussing that video, I am interested in how this guy is a chemist but debunks a bunch of projects that are mostly engineering and physics.
Were we all tricked? Is chemistry actually the true science with the most useful knowledge?
I hate that comic, he tries so hard to make the characters diverse, it's unrealistic

It is just a comic though. As long as all he is doing is using the paint fill tool with the color brown and not doing any kind of political pushing of diversity then it is fine.
Literally who cares.

Any I deas on how solve this? It's the first question of an ENS of Paris oral examination, it's supposed to be taken at the end of sophomore year. Also ideas in general to solve this kinds of questions?
Thx
>>8219670
First thing you need to do is to prove that
[math]\sup_{theta \in [0, 2\pi]}[\text{Absolute value of summation}] \geq \sqrt{n}[/math]
by definition of infimum as a greatest lower bound.
>>8219676
Just wrote that line to see how [math]\LaTeX[/math] would render. It looks disgusting, and I am sorry.
>>8219676
Yes I though about that but couldn't make it work
Keep in mind that the ENS takes like the 50 best math/physics student of France each year so that's not going to be enough
You should be able to solve this easily, /sci/
Yep, I solved it.

Why are a lot of people on /sci/ looking down on computer science degree?
Compared to majority of people with phys,math majors...etc. CS gets you way better quality of life, getting a job is way easier...etc.
I'm 22, I finally got the money for it and want to get a degree, I LOVE sci in general, everything really... but what I love even more is computer science in particular.
so what throws me off is when I see all of the people saying how its shit and how its not worth wasting money and time on a cs degree...etc.
So what's actually the deal with computer science? please explain in detail.
the deal is that panjeeb from duckaduckastan can do a 6 month degree and get your job
I love how geophys is in both the "good" and "great" tier.

>The correction is obvious: sets are generated by the human mind and are therefore finite. They are only as large as they’ve been created. By putting three periods together, one has not created an infinite anything. One has stopped thinking. Wherever the numbers stop, the numbers stop.
This is his real argument.
Just saved everyone 10 minutes of reading this.

he fails to contemplate the mind of god. Mathematics is about contemplating the infinite.
What a fag.
He points out how numbers are concepts, but for some reason must also simply rejects a purely formalist perspective on the cardinal aleph0.
Why?
>Mathematics is a theory with its own language, but unlike most theories, it perfectly maps onto the world. In other words, mathematical principles are not a linguistic convention; they are not a hypothesis; they are derived from the laws of logic, and they apply to all universes that are composed of existent things.

By experience, I mean some substantial degree of training or practice. At this point in my career, I don't have time to devote intense study of a subject matter that doesn't have direct application to my central focus. Hoping to hit that polymath master race status eventually though.

Difficult rigorous math seems really interesting. I accidentally took linear algebra thinking it was a pre-req for my major. We did a lot of proofs and I had a fun time.
