Retard here!
Looking things about cosmology in wikipedia, I found the article called "ultimate fate of the universe" understand their possible endings, but one I do not understand (maybe I'm a retard).
Just a little more understandable explanation, someone could help me?
Pic related.
>>8441825
Cosmology? I think >>/fa/ is where you should be.
>>8441839
It is a serious question... for me.
>>8441851
I was serious too. Cosomolgy is makeup and shit right? So that goes in fa
Did you know there are about 1 million words in the English language? Yet, using the latin alphabet (26 letters), we could form a total of 308 million diferent 6 letter words. What does the mean? The English language is highly ineficient!
Hereby I propose a new, efficient language: Tsm.
With only 7 different letters, each and every Tsm word will be up to 7 characters long. That way we are able to accomodate a 10 million word lexicon.
Why use Tsm? Fewer letters and smaller words will mean more efficient communication. Keyboards will be way smaller too.
Thoughts?
Your mum m8. Try to say that in your nerd language.

Ur mom, mate.
See? Way more efficient and totally intuitive for a native English speaker.
If you can't solve the retard test, you have no business posting on /sci/.

Anybody here already went through this?
How good does your calculus need to be to fully understand it?
>>8441717
basic integreals
>>8441755
No vector calculus, none of that?
I don't know much, but higher electricity and magnetism concepts involve higher forms of calculus right?
>>8441717
Upto Vector Calculus
why are med students and doctors such stuck up cunts who think they know more about nutrition than nutritionists, microbiology than microbiologists, better scientists than biologists or know more about sports science more than sports scientists, regardless of their field of specialization?
jesus fucking christ I hate doctors so much.
biologists and pharmacologists are the ones doing the real scientific work. doctors are nothing but overpaid technicians.
>>8441714
They know every one of those things relevant to general human disease and their own patient populations [in a specific area].
Nutritionists would be a but too specific in some ways but I agree they are more important. pharmacy is redundant, only ones doing the actual work or researchers who actually develop shit. >Sports medicine and biologist
lol. way to broad and it depends on the specialty. All I hear is a butthurt Med lab technician upset about their shit pay lol
>>8441714
Tell me who rustled your jimmies and I'll give you an honest answer.
>>8441714
Get back to me when you get a MD and PHD, brainlet.
Seriously what's going on here?
How do they cause charge to move?
Is charge crossing over the gap between the plates? If so, how?
>>8441691
So what's it like taking physics 2 for the first time?
>>8441694
How many times did you take physics 2?
>>8441703
Hopefully once.
Someone red pill me on petroleum engineering.
High-paying, mentally demanding, often involves international travel, working with some of the largest, most successful corporations to solve some of our society's biggest problems. What's not to love?

No way, I think it's the future for a long time. After all the tight oil and shale is sucked out there will be a big drive to recover used oil and goo from every nook and cranny in the machinery of mankind in one last ditch to keep civilization moving along. This will require petroleum engineers. Of course only the cream of the class will make it to that level, most will end up petroleum technicians...the hands on goo recovery people.
What is the next discovery/invention that will revolutionize the world?
Seriously hoping it's automated cars.
Advanced Machine Learning, I like to say.
>>8441538
I think automated cars will increase productivity and efficiency a bit, but I am on the fence as to whether or not they will revolutionize the world. We'll be able to work/rest while we travel, traffic might go away, maybe shipping companies will be able to get things out to customers quicker. It seems like it will just be a quality of life improvement.
I had a question /sci/ I'm doing an undergrad CS major with a Mathematics minor and I'm wanting to specialize in cryptography and hopefully do grad work in the area. These are the Math courses I was going to take:
Calc 3
Discrete Mathematics (two courses of this the cs bullshit one and the actual math one)
Linear Algebra
Abstract Algebra 1 and 2
Number Theory
Coding/Info Theory
and maybe a Mathematics software class?
I'm worried because this cuts out all the analysis related things (numerical/complex/real), and all the Diff Equations/ODE/PDE related things but I'm not sure if this is a mistake or not? Can anyone here speak to how relevant these topics are to crypto?
I also am really on the fence about whether or not I should take a Diff geometry class or a topology class maybe? I know these things are vaguely related to algebraic num theory, but are they essential?
I realize I can take any of these that I end up needing once I'm in grad school buuuut I would rather just start off on the right foot with a well rounded undergrad degree..
Quantum Memechanics.
Crypto is very cross disciplinary and what you mean by crypto is not well defined. Implementing crytography, "pentesting", are distinct from what normally constitutes academic cryptography, and then cryptography itself has different fields. Differential equations wont be too relevant, but you have no chance at understanding components of modular forms, elliptic curves, and arithmetic geometry that make their way into cryptography without even a basic analysis class. Take my advice and dont try to rush things your a fucking undergrad just take eat maths and like it.
How would you calculate the distance between the spacecraft and the galaxy they're looking at in this picture?
>>8441461
you can't
http://www.talkorigins.org/faqs/astronomy/distance.html
>>8441461
Wouldn't you have to first know how big the galaxy is?
Solve for the two indicated lines. Good luck
>>8441280
You can't solve that because it isn't an equation, it's just colored shapes.
This supposed to be a pepe you messed around with using a filter on photoshop?
Suppose that for all purposes, no matter what you believe in, the universe came from nothing
If there is such a thing, then wouldn't nothingness not even have "quantum potential"? As in, not even the possibility of a break in physics to give rise to the universe?
I'm not knowledgeable in physics, so that's the best I can express myself, sorry for my lack of actual knowledge
Just to try and consider the concept of 'nothing' is to meet the limits of human thought. There is nothing useful which can be gained by trying to extrapolate from the idea of nothing when we simply can't contextualise it or understand it in any way.
In b4 mathematics.
>I'm not knowledgeable in physics
then the first thing you need to educate yourself about is the difference between physics and philosophy. your question is philosophy, it is not something that science aims to or is even capable of answering.

I've been reading very extensively into LFTRs and the thorium fuel cycle, can somebody explain to me the fission chains of transuranic waste and how it can be simply fed into an LFTR and burned into stable transition metals?
Also this is not for my homework, but I do want all of the details.
>>8441106
Simple.
Thorium cycle doesn't involve Plutonium-239 products, which has a half-life of 24,000 years. This is the primary transuranic waste of Uranium-cycle LWR.
This doubles as an excellent non-proliferation advantage, which is the primary reason Thorium was neglected for reactor research. The Military wanted their nukes so they could play Brinksmanship.
>>8441331
*I should add that LWRs are not the only way to do reactors and other types of reactors have higher burn-up of fission products like Plutonium. A lot of this is done by altering neutron densities.
But none of this matters, because there is quite literally only ONE thorium-based reactor that is COMMERICAL (all others are Experimental) even being built in the next 10 years. And it is not an MSR, due to all the extra difficulties and uncertainties with that design.
>>8441106
>>8441331
>>8441347
I should also add that none of this matters in the end because FISSION is a dead-end.
The future is going to be Fusion, lead by the efforts of ITER and others such as the ARC Reactor at MIT. The recent advancements made in super-conducting electromagnets, necessary for plasma confinement is making Fusion is a reality. The big problem with Fusion was always in how to contain the Plasma for non-trivial periods. The next step will be understanding and creating better confinement chambers in the Tokamaks to withstand the neutron bombardment. That or switching to an alternative design like Lockheed Martin's energy amplifier, which intends to create a steady beam of neutrons that is manageable rather than have them go all over the place within a confinement chamber.
This is a really, really great watch if you are interested. It talks about where we are, how we got there, and what is next.

Thoughts on the IQ test?
I ask because /pol/ and /leftypol/ are talking about it again. Any hard evidence for/against either side?
What IQ test?
There are many different ones.
>>8441018
Sorry, I mean the idea of standardized tests which attempt to measure intelligience with an "IQ" - intelligience quotient.
Basically, /pol/ thinks that these tests are correct and they do accurately measure intelligience, and that one's score cannot be signifigantly improved via repetition or study. /leftypol/ argues that IQ tests do not accurately measure intelligience and that one's score can be improved through repetition and study.
The argument occurs because /pol/ argues that IQ tests show that whites (and maybe asians) are generally smarter than other races. /leftypol/ argues that this is because of the social and economic disparity between whites and other races, allowing whites to study more and repeatedly take IQ tests, skewing the results in their favor.
>>8441038
No one test is going to be 100% "correct", it gives the examiner a better understanding of cognitive functions, spatial reasoning skills, etc
