I don't think we are. And if we are, I really think we shouldn't care
Wait... If space itself expands faster than light, and this destructive wave can only travel light speed, doesn't that mean we can just "outrun" the wave?
what is better
solve an exercise alone
or look at the solution and try to understand?
The first is probably better but the second is way faster.
>>8397802
Look at solutions (or even better: a script or textbook) first and then practice it.
The exam will obviously not ask you if you understand a ready made solution to a problem, but it can definitely help having seen how it shiould be done.
>>8397802
>1) read theory
>2) follow example problems
>3) try to solve on your own
study in that order. it is a process, not just one easy trick

What's with all the schizos on this board today? It does seem to be worse than usual.
is economics the most patrician field?
difficult applied math? check
historical analysis and application? check
use of rhetoric and philosophy? check
how can physics, chem or bio even compete. Pure math is a joke as we all know already
Pure math led to the discovery of the RSA method you use daily for encrypted comms. No joke.
>econ
>difficult math
HAHAHHAHAHAHAHAHAHAHAHAHHAHAHAHHA
classic econ major. tell me econ major, what is a Fourier decomposition? tell me, what is an infinite dimension vector space?
>those have no application
lol, guess you have no idea what a cell phone is. Both of those concepts are key to signal processing and encryption.
good bait though, made me respond
>>8397763
Math major here and ever since I started reading game theory I started respecting economics more. Even though you are, like everyone else, inferior to me, I respect a field that does not pussy out like biology and accept that mathematicians are always right and start to apply our theorems.
Everyone else should be more like you, economists. If biologists and other faggots also learned higher mathematics then we could cure cancer in like a day.
>how can physics, chem or bio even compete.
Physicucks already accepted that we are better than them and started applying mathematics ever since Newton. Chemists are still fighting it but slowly they are realizing that mathematical structures and mathematical models make more sense for chemistry than the bullshit diagrams they have been shitting out for hundreds of years and thus now chemists learn group theory and graph theory... like they always should have.
Biology is the one that is a full pussy. I seriously do not understand how they can even be a science.
>Pure math is a joke as we all know already
Hey, don't get out of line. We gave you everything you have. Treat us with respect, you little shit. But oh well, you made me laugh. It is fun when people from inferior fields try do some banter.
Mathematicians are the kings of banter, bitch.
Are there any humans who commit suicide who do/did not suffer from any neuropsychiatric symptoms? Is this possible?
>>8397761
Does culturally-encouraged suicide count? The Romans definitely saw it as a acceptable or even honorable response to defeat and humiliation.

Sure, everyone can become tired of life. Life is pretty pointless.

post some challenge questions. I'll start:
Derive the Complex numbers from Real numbers without using the identity:
i2 = -1
In other words, that identity (or its dual √(-1) = i) should be a consequence of your formulation.

Only a handful of them may have practical implications.
Almost all the useful work is made in silence by physicists/mathematical physicists and engineers.
>By and large it is uniformly true that in mathematics there is a time lapse between a mathematical discovery and the moment it becomes useful; and that this lapse can be anything from 30 to 100 years, in some cases even more; and that the whole system seems to function without any direction, without any reference to usefulness, and without any desire to do things which are useful.

Off of this board with you pedophile cartoons.
So, /sci/, I'm new to the EM drive controversy. So, it violates Newton's third law and the conservation of momentum correct?
How is this thing even possible then. Is it just pop-sci bullshit like usual?
Its called the meme drive for a reason
>>8397672
Couldn't you play devils advocate and say that relativity was thought to be impossible at first?
Photons have momentum

When native English speakers refer to *reading* a textbook, do they imply studying it or skimming it?
In Italian I would say that I *studied* from Rudin reserving *read* for regular books.
Sometimes single pages from difficult books require a lot of time to be satisfyingly understood.
If you're a CS brainlet I doubt you were able to completely figure out some of the sketched proofs contained in the book.
I used it for self studying mathematics but I have some experience from several other analysis textbooks.
If you actually did it, then you're OK.
This device detects when you enter REM sleep and induces lucid dreaming by flashing lights against the hoods of your eyelids.
For the small price of 300 USD you too can control your dreams.
For free you can try controlling your life and make your dreams come true.
Isn't lucid dreaming all about being able to recall your dreams though by keeping a dream diary?

Carrier waves, signals and systems, literally all anolouge technology, harmonics, fucking anything.

This is probably a dumb question but I'm gonna ask it anyway. Are all electromagnetic waves a result of entropy within a system? As in, can you classify electromagnetism as a waste product that is irradiated?
Thing is I'm writing a book that is mainly biology/psychology/history/investing but I want to mention the findings that the temporal lobe is affected by certain electromagnetic waves, which in some people cause delusions. I'm an absolute layman in physics, at best, so I'd appreciate your input. In the footnote I explain what electromagnetic waves are, and I'd greatly appreciate if you guys could also tell me whether I'm even understanding it correctly:
" Electromagnetic waves are patterns of subatomic particles that are released as a result of processes requiring energy. The frequency at which the particles oscillate determines the type of radiation that they are. Everything from visible light, to x-rays to radio waves are part of the electromagnetic spectrum, and their prime difference is simply the wavelength that the particles possess. "
Thanks in advance

You should stop writing books about things you don't understand and consider suicide. It's already nigh impossible to wade through all the trash looking for a good read.
>>8397389
I shall consider it, but in the meantime...
Again, I AM NOT WRITING A GODDAMN PHYSICS BOOK. If you have trouble finding something to read, consider getting a Goodreads account, rather than harassing random people you know nothing about.
My book is mainly history, with a bit of social sciences mixed in. These are topics I understand well, but I also think my argument would be remiss if I don't include that tidbit about how schizophrenic people react negatively to certain elecromagnetic waves, and thus have to include a brief explanation of it. I'd agree with your assessment, if I was pretending to be an expert in physics - I'm not, by any stretch of the imagination. I said so in the OP.

Don't write about shit you don't understand. It's a pathetic attempt to be esoteric.

I have the worst ability to be able to focus on my studies and I don't understand why. I've always been this way and have always ran away from doing any
sort of academical work. I know that educations important, but for fuck sakes, I almost fall asleep in lectures when they waffle on about shit just to pass the time.
I tried adderall once and it was fucking amazing, everything felt as if it all made sense, thing is I dont have ADHD and due to being a 21 year old male, doctors
will jump to the conclusion i'll abuse it.
I have so many things on my mind at once that I cant sit down and do work for longer than 10 minutes. Doesn't help that I'm a programmer because having access to a computer just causes me to open a tab and search for whatever I was thinking about.
how the fuck can i kick my life into gear and focus on something, I love the feeling of achieving at my studies but it is so damn hard for me to get there in the first place.
I'm just sick of making excuses for my failures and want to change for good...
Also pleas share your study-, reading-, summerizingtechniques with me
>>8397359
Try reading out loud.
Or if that is not efficient for you, hold your breath for as long as you can while reading silently.
Are you interested in what you are studying? I would constantly fall asleep on analysis and physics lectures, and while studying them on my own, my mind would just go on its own adventures. Yet, when I read about things I'm interested in, I wouldn't even notice if someone cut off my limbs or fired a cannon next to me. This then lead to it that I'd fall asleep on lectures about interesting stuff, too, since I was already familiar with it.
Is having an internet connection obligatory for you? If not, then turn it off. If it is, there should be some extensions for browsers allowing parents to prevent their kids from going to bad websites. Use such an extension to block the sites distracting you.
One more thing! Try listening to music with long pieces, classical, prog, jazz, black metal, post-rock, etc. Not while studying, but otherwise. Develop your concentration by really listening through a whole piece. It lowers my anxiety and makes me functional, so there is atleast one person for whom this works.

Not necessarily your style, but this is one I've used to get to the state of mind required. A nice piece from a nice composer, and not even that long.
>>8397374
Yes of course! I love my subject, know that it's important for me, but got this extream procastinationg habbit, because of this lack of focus and concentration.
Interessting you mentioned music. Sometimes I've got the feeling that while playing music in the background, it seems to be a lot easier for me to study. I may should check htis theory and and work in this direction.
