What kind of things do you think Mochizuki would be able to achieve if he took Noopept™?

He could make some great shitposts on /sci/ about nootropics

What is the difference between a railgun and a coilgun? Which one is more efficient?
Also, if you had a cylinder filled with a gas like hydrogen, and you had a piston at one end with an explosive on the other side, and the velocity of the explosive's detonation was higher than the gas's speed of sound, what would happen?

>What is the difference between a railgun and a coilgun?
Wikipedia it. One uses rails, the other one or many coils.
>and the velocity of the explosive's detonation was higher than the gas's speed of sound, what would happen?
Piston travels down tube and compresses gas, you just described a Light-Gas gun which you can also wikipedia for details.
Why ask retard central something when you can wikipedia it instead?
What exactly is wrong with Wikipedia? Is the information on the articles trustworthy? Is it dogmatic or is there writer's or publisher's opinions presented?
So, what does /sci think of this encyclopedia, which announces itself to be free?
Decent place to get a general overview. If you want deeper understanding, follow the source links.

What exactly ido you mean by "wrong", fgt?
>>7962735
Wikipedia being wrong is just misconception of retarded teens.

Why haven't you joined the Triangle Fraternity?
>Triangle Fraternity is a social fraternity, limiting its recruitment of members to male students majoring in engineering, architecture, and the physical, mathematical, biological, and computer sciences.

Kek, they just started that this year at my school. It's a bunch of awkward engineer phaggots. Do NOT join an academic frat.
A long time ago, I had this free software that was amazing.
You put in some input numbers, put in a list of input numbers and output numbers, and it generates a formula expressing the relationship between the outputs and inputs.
Anyone know what it's called? Does it still exist? I'm an absolute moron with math, so it was a godsend.
Deep Thought.

It's called non-linear regression analysis. I made a program like this in Python recently and will release it as free software soon.
If it follows the scientific method, why would you say it isn't a real science?
You can conduct experaments and observe results and such.
How do you even decide what is and what isn't a real science?
>>7957443
Predictive power, reproducibility, ability to distinguish signal from interest variable from confounding variable noise
Psychology comes up shorter on all of these than hard sciences do
>>7957458
I'd say it has quite the predictive power and reproducibility. It's just "unethical" to conduct these experiments.
That last one is a difficulty most sciences had or continue to have but is made easier with the advancing of research environment
Let me ask you one thing, though. Are the findings of psychological research false? Do they not have practical uses in the world?
>>7957498
>I'd say it has quite the predictive power and reproducibility.
You would be wrong.
Autodidact here, I have this inane habit of finding the course books for courses at advanced colleges and studying them independently in my spare time.
Any one else here do the same?
What do you study?
Can anyone hook me up with some great course ware?

Geniuses are criminals for suggesting they are like everyone. People might actually believe that and waste their lives pursuing careers they have no chance on,

Feynman was actually a nice guy by being a prick to his students, rubbing in their faces how their research was trivial and irrelevant.
Pure physics/maths is only for the greatest.

What's the hardest semester you've had and why was it difficult ? I'll start with mine (I'm now in my 3rd bachelor year)
Computer Science, 2nd bachelor year, spring semester.
Courses :
Theory of computation : The teacher had no experience in teaching, this was his first year and he didn't seem to eager to do so either. The course covered many topics (set theory, graph theory, turing machines...) and every week we had graded problem sets where we were asked to provide proofs for difficult theorems on these subjects. The problem is many...

My hardest year is still to come, it's going to be the second semester of my masters (so in 2017), I'll be taking:
>Modern QFT
>General Relativity
>Hamiltonian Dynamics
>Differentiable manifolds
>Algebraic topology
>Algebraic geometry
It's going to be hard because I didn't meet the prerequisites...

The French are still best at math
When is this shit actually used in the real world?
>>7955331
set theory is used by physicists. When they say that ''the mass is 10 kg'' they literally believe that there is a number 10 floating in space and somehow giving you the answer on your measuring device..
Now, what framework for numbers ? it is set theory, where numbers are encoded as sets.
Since physicists believe that the mathematical inferences describe the world, when the inferences lead to quantified/numeric facts, they equally believe that the axioms of the set theory is true.
The...

I learned more from Reif which is almost 60 years old at this point.
Is it a legitimate concept or entirely hormonal or whatever?
I'm interested in any actual data about it.
The last edition of the DSM added an entry to clarify that it is not a mental disorder, and there are many people who identify as asexual who have had their hormones check and found normal. It is not the same as having a low libido... it is simply not wanting to direct their sexual desire towards anyone. There are asexual people who have normal or even high libido.
>>7953977
do asexual people masturbate?
>>7953995
Some, yes.
I'm not asking if because in my mind it's an inevitability. My question is WHEN. When will human driven cars not be allowed on the road? I believe we will have full on self driven cars on the roads in at least 5 years and at most 10. No way it'll be longer than 10. So with these self driven cars when will human driven cars be outlawed on the roads? Human error is the cause of almost every accident so self driven cars are definitely the future.
pic related. Stop lights will no longer be needed if all cars are in constant communication with each other communicating...

Intersections like that may not be possible yet because you cannot predict road conditions and such. Rate of acceleration/decelleration may vary.
And not every traffic collision is the fault of a human. Icy road and a large animal comes into the path of the car and it is unable to stop. Nobody is at fault. Infact a human driver may have an advantage as it could swerve into a snowbank and have a softer landing instead of hitting a moose that weights half a ton.
>>7952845
The onboard computer can sense road conditions because... you know... it's on the road. It can tell if it's icy or what not. Also I guarantee you a machine would have a faster reaction time than any human. They'll break quicker or swerve quicker.
>>7952843
maybe not ever. You can still see horse driven carriages on some roads today.
How do humanities articles differ from stem articles in your country?
>>7950862
humanities articles are better grammar and vocabulary.
stem articles are written by 12 year-old who can hardly speak but yet manage to think that they are pedagogical in their communication. Their topography is equally awful, since they think that it is enough to use latex to have a good article. The best part is when they leave a baseline stretch of 2.
Now the content. The stem kids think they have content because they cling to their fantasy of the relevance of the formal deductive reasonings, with a...
