can jet fuel melt steel beams?
It doesn't need to melt them when it can weaken them to the point of failure, and that's what matters.
Now it's time for you to leave >>>/pol/
the terror attack was real, but dick cheney and the secret services probably knew al-qaeda is planning something big in the usa and they all agreed on letting it happen because they all would gain politically from a big terror attack. this is the truth.
Phd in materials science here.
Tge rebeg constant of steel is aprox 1.58 and since most jet fuel is made with mendelevium which has like 3 atoms for each free electron it has a Hödge power of more than 3*10^5 spectral lumens and by Caeler theorem we know that it can melt things up to a rebeg constant of 6.39. So yes it can melt steel beams
Why did the Earth end up under the control of a type of primate and not to some other variety of animal? Is it really just something retarded like opposable thumbs? And will this same type of animal inevitably emerge supreme on alien planets too?
Try to think of some other appendage that would allow for an animal to use tools and create things with the complexity that humans do.

Cathedral termites do pretty well. Not the greatest architecture in the world, but maybe somewhere between abos and african humans.
>>8724617
This. And bipedalism to allow easy use of hands.
I'm not an evolutionary biologist though I know a bit and have posted at length in similar threads here. The prevailing assumption among most people is along the lines of, life on other planets wouldn't be humanoid because that would be a) too much of a coincidence and b) just egotistical of us to think so. But in previous threads I've asked for someone to post reasons why or how sentient, technology and tool-using life would or could develop along any other line than we have. It's harder than you think; just about everything in the human design has enabled us to get where we are, and it's difficult to envision any other design which could do the same. Perhaps a reptilian equivalent, like a Cardassian. But certainly not things with tentacles, insectoid forms, blobs of slime, etc.
Is the earth Flat, or Hollow?
Flat
Now get back.
>>>/pol/
its hollow but big govement tried to cover it up by putting rock and mineral in the earth.
>>8724539
No it's fat. REAL PLANETS HAVE CURVES!
>>8724447
damn, tough one.
guess it's something with arcsin (because of the form), but I don't have the patience to start substituting integrals.
>>8724447
Nice try. We won't do your homework, cunt.
Why do white people age so poorly compared to everybody else?
because of cherrypicked images in your meme picture
>>8724413
damn, good proof

please define what sub group of white skin pigmented humans you're talking about.
is it greek, russian, Italian etc etc
Is Khan academy good?

Have you tried using it?!
Like...you can answer your own question here OP
>>8724315
I don't want to waste time
For what I've heard, no
what exactly did this guy do, he has become a meme on here
and don't say Computer architecture, because that was really the work of Mauchly and Eckert
linear operators in quantum mechanics, and a million other things.

Game theory, among many things.

Before I write an email to my friend's tard physics professor, please let me know that I actually did this right.
Question: A car (m = 1250kg) travelling south at 1.30m/s and a truck (m = 4460kg) travelling west at 9.35m/s collide perfectly inelastically. Calculate the x and y components of the final velocity.
This should be simple, use conservation of momentum to find the final velocity via: [math]m_car * v_car + m_truck * v_truck = (m_car + m_truck) * v_final[/math] (assuming the car and truck are stuck together. You get v_final = ~7.59m/s. Then you find the angle in order to calculate the x and y components. The angle is found by putting the car's momentum on the x-axis of a triangle, and the truck's momentum on the y-axis, then use using the tangent formula to find that theta = 2.23 degrees. Then you take that angle and plug it into another triangle, where the final velocity is the hypotenuse. Solve for the x and y components using sin and cos formulas and you should find that the final answer is (-7.58, -0.295) and is using exact numbers every step along the way only rounding down to three sig figs at the very end.
Obviously the professor could have rounded more sloppily than I, but this dumb cunt's final answer is (-7.30, -0.295). That cannot be correct and even though I know this confidently, my friend doesn't trust me so if you could just confirm that the professor made a mistake (or is a dumb cunt) so I can show my friend, that would be very appreciated.
You dumb nigger, if the collision is perfectly inelastic then all kinetic energy is converted to heat. You're even more retarded than the professor.
>>8724298
It means the two objects stick together, retard.
>>8724281
>dumb frogposter
>makes retarded mistakes and blames prof
Fucking use the law of momentum conservation for X and Y axis separately instead of going into trig to solve an easy as fuck problem.
What are your thoughts on this guy, /sci/?
>>8723357
he has a method of talking about science that gathers attention from people who would otherwise be preoccupied with more tangential things.
He pisses off people who devote their lives to science becuase when you really devote yourself to something you often lose the ability to relatably communicate that information to people not as involved with your studies
Good orator, kinda handsome, not too sure about what he does scientifically.
>>8723357
I don't watch TV, so he's just a guy that makes an ass out of himself on twitter regularly.
How do I come out to my parents as an engineer?
My family is pretty liberal so I do expect they should accept me.
I don't know how I am going to tell my dad that I am not going to become a physicists like every father before me for past 12 generations.
Is it ok to become a physicists and do engineering on the side or is that just internalized engineeringphobia?
>>8723337
Or, become a good engy and work for CERN or Fermilabs?
And then make your kids get into physics.
come out as gay first and they'll figure out the engineer part
that's the easiest way to do it
>>8723337
Repair the closet.
Will taking intro to psych to be near a particular girl destroy my GPA?
I'm not very artsy and the unit coordinators name literally ends in stein.
I'm not biting
Still enrolled in psych
Got until Friday to change
Need some answers pls
psych 1 is easy as fuck, you don't have to be artsy or creative, you just read the book and learn the information.
If you're so smart why are you on 4chan.
I'm to smart too browse other websites

t. maths major so i'm little biased, though :3

Who or what is your intellectual motivation /sci/? What do you study for and who do you want to be like?
Pic fucking related
studying helps to distract me from my crushing nihilism
To keep my mind off being a worthless stoner and drug addict.
Is TerraPower the way to go with nuclear energy?
>>8722727
No. NuScale is gerting NRC approved much, much sooner. Terrapower hasn't even started the process.
>>8722737
Never heard of NuScale. It seems to be going live in the mid 2020s at the same time as TerraPower says its first commercial plants will be live though.
I'm not certain TWR's are feasible without very large and very enriched starting fuel loads. Nuclear power has a capital cost issue (mostly driven by the red-tape filled regulatory environment) and I think this will make it worse.
>>8722818
Terrapower haven't begun the licensing process while NuScale have.
Does 1+1+1+... = 1/2 or -1/2?
depends on whether the riemann hypothesis is true, false, or undecidable in ZFC
(it's equivalent to the wave/particle duality)
