Hey there /sci/, /lit/ here.
Can you produce an example of one relevant scientific problem that wasn't based fundamental philosophical assumptions?
Thanks.
>>7756850
no we can't, why do you ask?
>>7756850
Nah
How is a problem based philosophical assumptions?
How do we kill sociology?
Or just fix its incredibly broken academic community?
What's so broken about it?
>>7756562
Replicability and Politics
>>7756559
The way to fix it is to get them to study the way the world works as opposed to the way they want the world to be.
Economics and power drives all human relationships, social norms develop only because the power that be endorse them and they are powerful because they have a monopoly on military power and knowledge. The powers that be endorse them because those social norms serve their power in some way.
Society is ruled and controlled by money, "money talks", everyone without exception is a self serving dis-ingenious prostitute that serves the powers that be by serving themselves through that phenom we call the dollar. People want to matter because their stupid brains equate that with a better survival and reproduction rate.
If you were special you wouldn't want to be special.
I enjoy studying mathematics as a hobby, mainly, and right now I've been pushing my way through into the land of formality and axiomatic systems. They were not joking when they said it was going to be traumatic.
Now, the question I've got is if it's possible to study mathematics on a higher level, as a hobby? I'm no genius but I'd like to believe I'm smarter than average. I primarily just enjoy playing around with ideas and discovering things, but I'm pretty awful at proofs and formality, although it's getting better, since I normally just think intuitively about these things.
The last question I have is for those that perhaps study the subject at university, and that's about the connection of intuition and formality. I realize formality is really important, but surely when trying to prove or solve something, or discovering something new, do you think formally? It's an intuitive process THEN put into formality to make sure it is correct, right?
Yes.
Yes.

It's incredibly important to have an intuitive understanding of every concept you study. If you don't, you're just learning text and algorithms.
Tadashi Tokieda put it like this: I'm not proficient at reading sheet music, but i know people who are, and they can read sheet music and "hear" the music while reading. When you just start out learning how to read sheet music, you just learn what every line means, and maybe you read something like G A B F E etc. You're not hearing the music. Similarly if you're just learning to play the piano you'll find that it's usually easier to play a song from memory than from a sheet of paper. When you get better at both, lines blur and the two start overlapping.
That's what mathematical formality is. You have to feel the maths as much as you know how to read it. When you do, proofs will come much more easily as well. Very few Theorems are strictly formal, usually they're a formalization of an idea.
Should high intelligence be classified as a mental illness?
1. High intelligence is abnormal (statistically very rare)
2. The ones affected by it are suffering. High IQ people tend to get bored quickly when having to deal with average brainlets. They suffer from alienation and from social stigma / bullying. Also they are more prone to severe depression.
3. High intelligence causes suffering to other people because they get envious.
Discuss.

lol
Should being OP be classified as a mental illness?
1. Starting new threads is abnormal (statistically very rare)
2. The ones affected by it are suffering. OPs tend to get bored quickly when having to deal with no replies. They suffer from alienation and from social stigma / bullying. Also they are more prone to severe faggotry.
3. Being OP causes suffering to other people because they have to wade through countless shit threads to find one or two worthwhile.
Discuss.

Autism is already considered a mental illness.
What courses are you taking next semester?
Real Analysis 2, Honors Algebra 2 and Topology.
Methods of Pharmaceutical Sciences, Pharmacokinetics and Membrane Dynamics
Technical Writing
Calculus(hopefully, currently studying to place into it)
Communication SHIT
Social Science SHIT

Is it easier to heat something up or to cool it down?
Depends on many variables. Heat moves from hot to cold so assuming you had something like a fire to heat an object up, but only air to cool it down then it will heat up faster.
What do you mean easier? It requires the same amount of energy.
>>7755708
Pretty sure lack of heat is a universal constant where there aren't suns providing heat
>A broken clock is right two times every day
What if my clock (B) was broken in such a way that it ran at 1.5x the speed of a reference clock (A)? How many times on average would it he correct every day?
What if my clock (B) ran in reverse at half the speed of clock (A)?
What if clock (B) accelerated over time at a rate of X^2?
Can you generalize this into a formula to determine the maximum, minimum, and average number of times clock (B) would be correct with respect to clock (A) on any given day?
Broken clock usually means clock that doesn't run at all though
The rest of your question is just high school level physics problem, and probably your homework
>>7755688
Is that your way of saying you can't solve the problems?
The difference of amounts of revolutions per day is equal to the number of intersection as long as they have constant speed.
Hey /sci/,
I'm trying to program a function that simply takes an integer, but cycles through all non-grey RGB values (i.e. one value is 255, one value is 0, one changes). My current method requires a lot of if-statements, so I was wondering if there was a mathematical approach I could take. The value of each color's brightness has a trapezoidal waveform, and so far I have this function (couldn't get latex to work for some reason so bare with me):
(255/pi) * [ sin^-1( sin( pi/2 * x ) ) + cos^-1( cos( pi/2*x ) ) ]
However I want to "stretch" just the horizontal parts so they last for a longer interval (picture is a visual explanation), so that the values read as follows:
x=0, y=0
1 <= x <= 3. y=255
4 <= x <= 6, y=0
Any ideas how to achieve this mathematically, without resorting to piece-wise?
>>7754984
Op here
To clarify, I want to preserve the characteristic that the wave goes from 0 to 255 in an interval of 1, or [x,x+1], so normal sinusoidal stretching won't suffice.
So /sci/, for a whole day I've had this very weird feeling.
It's as if the back of my brain is moving inside my head when I move it too fast.
Please tell why the fuck this is happening because everyone else has been unhelpful.
>>7754898
Please, is this shit dangerous
>>7754898
Please
>>7754898
you could have an injury to your cervical spine causing instability
which wouldn't be all that dangerous just massively uncomfortable
I wonder if it's possible to use lust as a motivation for doing productive things like studying. For example don't jerk off for a few days and then every 15 minutes of studying allow yourself to jerk off but not cum for 1 minute. I wonder if you would just be distracted while studying, or if you'd overall be more motivated to do it. Does anyone know of any experiments preformed on this?
>>7751776
that sort of thing doesn't work for me. sometimes i get horny while i'm studying and i gotta go take care of it right away or else i can't study
>>7751784
Have you actually tried to just not?
Lust is too strong for the mortal man.
Okay /sci/ does anyone have any experience with the application process to become an astronaut? Whether you completed training or just sent in a resume, I'm wondering if anyone here has taken any steps at all to go into space.
Right now I'm only a few semesters from finishing my Bachelor's an seriously considering applying to flight school with the US Air Force. I do have prior experience in the military, although in a different branch, so spending a few years in the USAF isn't something I'm worried about. I want to do flight school to get some time behind jet aircraft before sending in an application to NASA to see if I can get into the Astronaut Trainee program. This is all what-if and hearsay, of course, but I want to see if anyone on /sci/ has done anything relevant to this.
Have any of you done any applications into NASA's astronaut training programs, and is pilot experience really as valuable as they say?
>>7750913
Why do you want to be an astronaut? You'll just be a technician, but worse still you'll be a technician that the government had flung through the air ridiculously fast.
>>7750929
But do I die? Not that anon, but really interested to know
>>7750929
probably because this guy likes cleaning stuff for 7 hours a day, kek
stupid question thread:
I'll start. Pic related, how do I do this I realize that
[math]V=-\int \vec{E} \cdot d \vec{l}[/math]
But that's all I got
How is energy conserved in special relativity?
If you have a system containing two moving objects with one having a mass that is much greater than the other's, would the energy be the same regardless of which object's frame of reference you are in?
can someone recommend me a youtube channel to teach myself the first semester of Physics with calculus?
Does anyone know how to make a LOCK out of paper? It doesn't have to resilient. Just a lock that you have to enter a combination somehow to make it unlock?
Maybe a paper bent in half with locks made out of tiny paper strips with strings on them?
>learning maths from scratch
>just learned how to solve simultaneous linear equations through substitution and elimination
>so far it's all much easier than I anticipated
When do things get challenging?
>>7761826
How's highschool, bud?
>>7761830
I'm not in high school. Not everyone goes through a cookie cutter life. In a few short years I'll know more maths than you, so fuck you, cunt.

Attitude of a child. Underage confirmed
At what age did you learn S.I units?
Do americans learn it before university?
>>7764988
They're taught in elementary/middle school and high school physics classes use them.
>>7764988
I've known SI Units ever since I had a memory, but I had to learn the silly imperial units, because we used american books in high school.
>>7764988
desu until I enrolled into m community college (19 y.o.), then again I dropped out of high school.
Petition to replace captcha on /sci/ with mathematical equation.
Bump here if you support this. Only unique IPs and posters will be counted.

Nope :^)
It should be a quiz about our favourite scientists.
