You could take the word "non-zero" out of every sentence in which it is used and it wouldn't have any affect on the meaning.

I just finished a multivariable calculus course and went to check my final.
This is one of the problems I got wrong.
Does anyone know how to graph this properly?
>>8048474
It's a degenerate hyperbola
x^2 = y^2
=>
± x= ± y
That's both lines
>>8048488
Sorry, should really change
± x= ± y
into
x = ± y.
Same thing.
>>8048474
are you talking about the function [math]f(x,y)=cos(1/(y^{2}-x^{2}))[/math] ?
be more specific
Do you think the Collat's conjecture is true /sci/?
what do you mean by true? It works, but it hasn't been proven or solved yet
>>8048464
Do you believe it is true?
>>8048467
Its probably true
Can aeromodelling be considered science?
It's an applied use of several branches of science.

I am sure she developed it in her room, not in space.
Fucking jews, learn to fucking construct a coherent sentence.

Molecules with the same number of atoms arranged in similar way but reversed, like they a mirror effect on them.

Completely fucked up math education
Hey /sci/,
If (for example) string/QFT are some of the forefront most advanced forms of physics being researched at the moment,
What is the most advanced/difficult/theoretical form of chemistry being researched?
consciousness :v)
nice dimethyltryptamine, fgt
>>8048027
it's not DMT though, b/c that's a dihydroindole in the pic
>>8048484
Uh, no?
Greetings, /sci/.
I am confident to have made a most relevant discovery in the field of chemistry/physics.
I would like to share it with the scientific community.
How to write a scientific paper, thesis, etc, so it can be published in a big magazine like Nature? Who do I contact, how to make sure people will not steal my idea, how to spread the word to as much people as possible, etc?
For the purpose of credit I will not share any detailed information about the contents of the discovery itself.
>>8047864
you made an important discovery by yourself, isolated, with no supervision?
talk to your professors. you don't know professors in the field? then that's a huge red flag, 100% chance you didn't discover shit
>>8047870
>talk to your professors. you don't know professors in the field? then that's a huge red flag, 100% chance you didn't discover shit
ignore this elitist anon
publish your work however you can, usually conferences are easier than journals
you do NOT need an academic institution behind you, plenty of research is done by private sector companies and individuals working for them
>>8047907
>elitist
dude. if he has no education on the subject, and doesn't have a lab or know people who do, how the fuck would he make a breakthrough in chem / physics?
you're really giving him too much credit, waaaay too much.
Hi, I don't know if this is the appropiate place to talk about it I will go on another thread, does anybody know how a robot moves on a metallic strip or/and tape?
This thread is cancer, badly written and I am a faggot
>>8047767
Google line follower robot, it's a great beginer robotics project.
Here is an example of how to make one
instructables.com/id/Line-Follower-Robot/
Basically the robot has a strip of color sensors on it's front and tries to turn such that the black is in the middle.

I want to get a german one, not an italian one, because german shit is low price/well engineered and italian shit is high price/high aesthetic/ poorly engineered. I drink about 12 expresso shots a day and i want a good machine that will pound them out. Is krups german? I cant seem to find which makers are german and which are itrashian

You could start by spelling espresso properly.

Wow that distorted sine wave would sounds pretty cool
>Dr. Gates, is an American theoretical physicist, known for work on supersymmetry, supergravity, and superstring theory.
Thoughts on Dr. Gates's work /sci/?
>>8047586
He's a great supporter of the simulated universe theory, he's working with other great minds to prove it true. Brilliant man, my role model.
It's super

I love this guy
Why all matter in Galaxy spin in the same direction around its center? How can matter synchronize it's movement on such giant distance? Why matter around massive object forms disk instead of sphere? At the beginning it falls on the center of the mass chaotically in different directions and then something arrange it.
Imagine you have a solar system that's still forming. Some dust is going clockwise, some dust is going counter clockwise (1). Eventually, the dust is gonna collect itself under gravitational influence, and the newly formed dust grains/ rocks are going to crash into each other, going opposite directions and all(2).
Eventually, dust/ rocks going one way will eventually be eliminated by the dust going the other if the majority of it is larger (3) and fall into that dust's gravitational influence.
Eventually everything in the system will orbit one particular way in order to preserve momentum as it experiences a gravitational pull from the sun.(4)
It's the same with galaxies and planetary rings.
>>8047567
These clumps interacted gravitationally, putting tidal torques on each other that acted to give them some angular momentum. As the baryonic matter cooled, it dissipated some energy and contracted toward the center. With angular momentum conserved, the matter near the center speeds up its rotation.
Now you don't know, but that's cosmology; story telling.
