nicely meme'd friend
>>8133812
Religion is higher than psychology? What the fuck?
Has studying blackholes and pulsars or any deep space object yielded any practical applications?
>>8130002
Helped develop new models for your mom's gravity field.

OOOOOOOOOOOOOOOOOHHHHHHHHHHHHH!!!!!

20-80 hyperloop theorem (science reasons - hate it, for all my life)
100% came first. The Universe jizzed itself, when it did the only sure thing. Then it started to move. Then it deduced that experiencing the moving would be a fun thing to do too. Then the experiencing and moving got things jazzy (time was deduced). Then it deduced 120% and 6-sided figurines (time reasons). It was the first time it did two things at once, and then it split the information into two – three spatial dimensions and three time dimensions.

Need to advertise, I'm sorry to all.
Electronvolt is a word to describe electron's quantum movement through space.

When did you decide to dedicate your life to science?
>>8134762
When I got in an excellence program. In another universe I'm pretty sure I would be a codemonkey.
>>8134813
>excellence program
what is an excellence program?
>>8134868
It means i'm better than you
Try harder
How is the second true? I've seen in some cases this can be used but not all the time
>>8134755
If B implies A. In other words if B completely contains A.
>>8134775
the opposite of this. B is a subset of A
Should research institutes and universities exist outside 1st world countries? Usually they are way behind the current development, and are not even able to replicate or understand old result, less do something new.
Let me be more specific:
- poor people do not see or understand the causality, the cannot the difference between correlation and causation,
- they cannot handle facts in a systematic way, there is no tradition of doing so, even if they do the knowledge does not pass to younger generations,
- doing science requires peace of mind and your material needs to be satisfied, poor countries are always unstable which makes you think more about survival, not the nature of the universe,
- if you are poor you feel insecure and do not share your knowledge with anyone, nor talk openly about your research, this slows the development.
- even if poor people visit foreign universities they are forced to do what their supervisors required from them, when they come back, everyone is doing their own subject, so there is no coherence, just chaos,
- it ends looking like the cargo cult, and is an offence to rational thinking and common sense, moreover they are made to publish a lot which ends in publishing shitty, poorly written papers,
- last but not least, young intelligent people have no incentives to become researches, work in foreign company is better paid and often easier, and they see the misery of the elder
In the ancient Egypt the knowledge was kept by priests. You should go back to that pattern and stop tormenting subhuman creatures with things they are unable to cope with.

>- poor people do not see or understand the causality, the cannot the difference between correlation and causation,
your reasoning is simply unquestionable
there should be a law making it illegal for any countries outside the US, Canada, Europe and maybe Japan and South Korea to have universities, instead they should focus on issues that affect their poor population like buses and running water
>>8134698
>they cannot tell the difference between
maybe not a law but just a principle
one cannot simply skip several hundred years of development and claim everyone has equal chances
it is a lie
>>8134985
No one wants "development" à la West.
6 billion people actually make fun of you guys because you're only driven by money and think you're actually free.
The truth is you're afraid that people in poorer countries focus more on engineering than on liberal arts.
Liberal arts pleb here
I'm taking some low level physics course right now and I'm having a little trouble understanding dispersion/refraction.
I get the basic principle, that light propagates at different speeds through different mediums.
Refraction is the change in the light's vector/direction when it passes through a certain medium, correct?
And dispersion is the act or process of light being separated into its constituent components, right?
Why does light change direction when entering a different medium?
What exactly...

>>8134362
Also, what is dispersion ration/ index of dispersion, and how does it differ from refractive index?
>Why does light change direction when entering a different medium?
The best way to explain this is with the wavefront theory of light. Imagine you have a point light source, and imagine the light radiating from the point is doing so as fronts of concentric spheres. Each sphere is one wavelength apart and these are known as wavefronts.
Now imagine a point source very far away, and to keep it simple lets only do 2 dimensions. The wavefronts are now circles, and far enough away from the point source the curvature is so large that small sections...

Alright I think I can follow that. How about the rest of my questions?
>there are more atoms in the sun than there are grains of sand on every single beach in the whole world
really puts things into perspective
>>8134283
No it doesn't you dumb fuck
>>8134287
Yeah, theyre SOO big but we are all very small, but even they look small in our sky, shows you how big we really are. Where did you learn philosophy, Arizona?
>there are more atoms in a grain of sand than glasses of water on the entire sun
Electromagnitism travels by photons
Strong Force travels by gluons
Weak Force travels by bosons
Why haven't we discovered/disproved the existence of "gravitrons" yet? Is it possible to even devise a test to discover such a particle?
>>8134205
Fuck particle physicists and their incessant need to make everything into particles
>>8134205

bullshit
I'm doing Physics for the first time in 8 months and I have an exam tomorrow determining the future of my life.
I need to be tested on the following topics:
-Mechanics (projectile motion, momentum, forces, work+energy+power)
-Materials (density, stoke's law, hooke's law, pressure, young modulus, elastic strain energy)
-Thermodynamics (heating, molecular kinetic theory, ideal gas equation)
-Further Mechanics (impulse, kinetic energy of a non-relativistic particle, motion in a circle, centripetal force)
-Oscillations (simple harmonic motion,...

you can't learn that in 10 hours. give up.
if it determines the future of your life you should have thought about it in the previous 8 months.
also: electricity (p.d, resistance, electrical power, energy and efficiency, resistivity, current)
>>8134003
but I can. I can memorise the equations and definitions. I have pretty eidetic memory, its just I don't have the resources right now and don't have time to create them from creative sources
seeing as there's no health board or psychology board, you're my next best hope.
Is pic related a chemical imbalance/serotonin deficiency or just cognitive behavioral abnormalities? for the longest time I try to justify it as the latter because I hate being a special snowflake but no amount of meditation has gotten me anywhere.

>Let's ask /sci/ questions that haven't been solved, they sure know.
Christ I want this meme to end. If you want armchair psychologists to make up bullshit to answer your question you might as well go to Omegle and ask there.
>>8133910
In a similar vein, let's not ask /sci/ how the universe was created, or how black holes work. gg mate.
>>8133872
Take SSRIs and compare results.
Is there any way to prove that:
[math] \frac{1}{x+y+z}=\frac{1}{x}+\frac{1}{y}+\frac{1}{z} [/math] ?
fuck me, I meant:
Is there any way to prove that:
[math] \frac{1}{x+y+z}=\frac{A}{x}+\frac{B}{y}+\frac{C}{z} [/math] ? For any A, B and C
true for x=y=z=0
Which set of equations govern everything we know in the universe? Is it really just these two (in natural units)?
[math] \displaystyle (i\partial/-m)\phi=0 [/math]
[math] \displaystyle G_{\mu\nu}-8\pi T_{\mu\nu}=0 [/math]
If not, what other equation(s) need to be added to include everything? I guess you could argue that this could be added to the mix:
[math] \displaystyle H^2=\frac{8\pi}{3}\epsion-\frac{\kappa}{a^2R_0^2} [/math]
What does /sci/ think?
>>8133408
>Which set of equations govern everything we know in the universe?
no such thing
> Is it really just these two (in natural units)?
definitely not
>If not, what other equation(s) need to be added to include everything?
A lot
>>8133408
The universe is not describable in closed form.
>>8133429
proof?
why do men have a better body and mental capabilities than women?
what's the evolutionary and genetic reason for this?
inb4 first programmer was a woman
we all know the true story
>>8133352
because they have to work, while women have to raise children.
men and women are not meant to be equal.
hey /sci/, what kind of math is this? what do I need to learn to understand this? I feel so fucking stupid :(
>>8133294
chain rule
>>8133299
I think these are matrices, right? How does chain rule work on matrices? Also, notice that circle with dot inside? wtf is that?
>>8133306
It works the same with matrices and vectors.
It looks like calculus of variations potentially just with a lot of random shit in it.
Where did you find this?
