HOW THE FUCK DO I ESTIMATE LOGS??
REEEEEEEEEEEEEEEEEE
Power series.
Very carefully
>>7969583
how does this work?
Is /sci/ interested in books and shows about science fiction? Realistic ones, say, with actual science
>>7969349
yes.
Also, much of science fiction has basis in real science. Probably not the movies/books you've been subjected to. A lot of sci-fi books have realities that are theoretically possible, or totally possible just maybe not logical if said logic is to be applied to the world you and I live in.
Authors like Isaac Asimov and Arthur C Clarke.
Ray Bradbury is a good author as well but many of his stories or closer to fantasy than sci fi.
>>7969353
Thank you.
What about a book set in the very near future, with weaponry that's only just beyond our scientific grasp today?
>>7969349
Ye like xdiles
Is language merely an accidental byproduct of more complex thought patterns?
>>7969347
Chomsky says yes
>>7969350
Chomsky also thinks there is a universal grammar
I am taking an intro to physics class, physics 101 essentially, the professor is a goddamn nincompoop. He doesn't know anything, it's so sad and pathetic can someone here help me on my journey of discovery. Can someone here on /sci/ help a anon out. I am a biochemist and I have never taken a single physics class not even in high school.
>>7969071
I need to take 8 hours as a pre requisite to get into medical school, however I have never been satisfied just memorizing things I need to truly comprehend it
>>7969071
I need someone to teach me so I could learn, it is unfortunate that I gave my money to this jokester because he is incompetent. stop being dicks and recommend some materials
>>7969100
Suck your own cock faggot.
You know calc? Apply calc to the material. Use MIT open courseware and the many free tutorial sites. Those are kinematic learn force diagrams and their rules.

you link a subject for biology students.
what do you study and what do you want to do ?
>>7969052
Oh really? That test is math for bio students? I may be worse off than I thought then.
I have been involved mostly in combinatorics and graph theory projects including the Bruhat graph combinatorics and forbidden Berge subgraphs problems. I have also been involved in a few projects in mathematical biology and one in space physics. I hope to study pure math at ENS. I would like to study rings but I don't have experience in this area beyond my coursework
>>7969052
wait what do bio students even need math for?
If the sun were scaled down to the size of a tennis ball, how hot would it be?
Could we hold it in our palm?
Note, scaled down to size, not "compressed" down to size.
>>7968960
This makrs literally no sense.
>>7968966
I think he's trying to say how hot would a tennis ball size piece of the sun be
That doesn't make sense anon. You can't scale down atoms of hydrogen and helium.
Even if you could shrink it somehow why would that affect it's temperature?
Is real life "memoryless". That is, does where the universe go next depend entirely on its current state only, or does one need to know the history of the universe in order to predict its future?
>>7968951
Both.
It will be perpetuated by events of the past, of course, but inductive reasoning will only get a human so far.
>>7968951
Real life is a gigantic open markov chain network.
Hello /sci/ I was in physics lecture (waves and optics) and I asked the professor if the intensity maximum of slit experiment light increases if the number of slits increases.
At first he thought they did not and the intensity remained the same, but then I talked to him again after class and expressed how I thought the intensity would increase as a function of the integral.
Online MIT and Georgia Tech lecture notes always show the maximum intensity as one as the attached image shows. Is this correct? I think the intensity would increase as the interference decreased....

Total area is conserved so peak heights must increase.
>>7968952
That is what I was thinking, could you explain why the area must be conserved?
Also why does MIT and Georgia Tech both have it wrong? I guess NYU as well because the professor did it wrong at first.
>>7968949
as the number of slits increase, the distance between each slit decreases (we want to keep the original area that light strikes the same to ensure we are always talking about the same incoming energy). We know that for diffraction gratings, m=d/lambda where 2m+1=max number of bright spots. Since d decreases, m also decreases and the total intensity f course stays the same. So it seems you're correct that the more slits a grating has the higher the intensity of each spot.
The Chinese, and possibly Russians, are sending people on a one way trip into space. Why does the US government give one flying fuck if people want to possibly volunteer their lives for the exploration of space? I don't want to die of old age.
Anyone psychologically deficient enough to throw their life away to hurl into space and not come back is not fit to be in charge of a spaceship

>clouds are behind the sun
wrong
the sun is behind the clouds
the clouds are really far away too.
have you ever touched a cloud?
didn't think so.
>>7968894
Wrong! The sun forms the clouds and they float through space toward Earth.
Hey /sci/ I want to transform pic related the orange into a simple function.
So that I can predict the boiling point of any n-alkanes by doing simply math.
Is there any software for that?
It look like a log function to me
I did some excel stuff to get a standardized evolution to erraze little mistakes.
How can I get the global function?
>>7968812
>what is excel
Other pic.
Hey /sci/, I've been busting my ass with gen end courses and have about 3.7 but I'm about to start getting into the physics/Math courses making up the bulk of my engineering major.
This summer, I'm deciding on getting a tutor or two in order to help me set a strong foundation in order to really grasp and get a semantic understanding of the maths and physics needed.
I want to get to Calc 3 Levels and pretty high in physics.
Are there any subjects that you guys recommend for me to really focus on over summer for a MechE degree which may eventually...

What's going on in this picture?
He's trying to prove e=mc^2 by using only the quadratic formula, a cube, a parabola and a random equation.
That's pretty impressive if you ask me
>Okay, Jeffrey, and everyone else! Listen! Get in position for the photo. Wait, why is nothing written on that board? Can you scribble some formulae down so our audience knows it's a maths class? Google something, quick. "A=1/2 bh" is apparently the area of a triangle, can you draw a triangle? Can you draw a cube somewhere else? Write E=mc^2 too. Quadratic formula should be good, and can you sketch a quadratic too? Okay, we're running out of time, just get in position!

It is (0) of a numeral system.
m = E / c^2
Mass is nothing more than a property of energy.
Explain /sci/
>>7968486
Not a property of energy. A state that energy can be in.
>>7968486
>nothing more
You are nothing more than an idiot shitposter.
Explain.
How can mass be a property of energy if energy isn't anything physical? Isn't energy just a property of mass?
