If it's raining uniformly at a constant rate, will I get more wet if I stand still or run on a flat surface?

You'll get more wet if you stand in the rain like a retard you fucking idiot.

But you only run to get out of the rain.

Could it be possible that there is life in interstellar space, like in nebulae for example?

every thought you have is just some electrical energy, distributed in a certain way

what's a good book for a relative normie to understand things, in a layman's way, like theoretical math?

I like learning layman's theoretical physics, and I was curious about math

The /sci/ site books page has quite a few choices, and links to where you can get them if interested. It also depends on what you are curious about. The page is broken up by topic so take your pick, not sure how up to date it is though. https://sites.google.com/site/scienceandmathguide/general/books

I graduated with a chemical engineering degree over a year ago from a top 20 American University and possess an EIT certification.

For the life of me, I can't find a job. I've sent out over 300 resumes, cold called companies, contacted network connections from school, showed up to companies with resume in hand...I've broadened my search to other engineering disciplines, looked outside of my state, and even volunteered free labor to large corporations.

No one will touch me. My GPA is on the lower side, though I had good reason for it during school and my work ethic and quality is admirable. I'm starting to lose hope, I recently accepted a job at a local coffee shop as a barista because unfortunately my financial situation cannot cope with another year of unemployment.

Does anyone have any sort of out of the box suggestions? I can't help but feel I really wasted my time working so hard for my degree - people who partied hard in college and majored in sociology found careers, while with the so called STEM promise of a decent career I'm left on my ass.

What did you do to get your first job? I don't have any family or friend connections in an engineering field.

I've reviewed templates and have a friend who works in HR (in an unrelated field).

Got any quick tips or resources I could use to buff up my resume? I don't have any applicable engineering experience, though I do have work experience in unrelated fields.
>>
If you aren't mentioning how well of a team player you are you ain't gonna make it, did you do some sort of team project either extra curricular or not?

If you have a lower GPA (how low we talking?) you need to bring other stuff, eg tea working, management experience

I need some help with an algorithm. I'm attempting to write an approximation to vertex cover using the bipartite homeograph of a planar graph but I can't figure out how to actually construct this homeograph. They make it seem simple--"just turn every face into a vertex and make an edge to its adjacent faces", but I dont see any algorithms on doing that for undirected planar graphs.

>>7932562
I can probably use the boost library's boyer myrvold planarity test to generate a planar embedding and use that in the planar face traversal, but this doesn't tell me how to get the adjacent faces for a geometric dual or even how the algorithm works
>>
what data structure are you using for your graphs?

the algorithm to construct the homeograph certainly depends on how a graph is stored.
>>
>>7932620
literally just an unordered set of vertices and a vector of edges, in no particular order.
I'm probably going to use boost now

If Diamorphine (Heroin) and Alcohol are both very addictive (topping the charts), than how come alcohol can be used so frequently by people, without getting addicted to it (forming some kind of dependency), but heroin is portrayed as making you addicted to it way "easier" (I heard people saying that 3~5 consumptions is all it takes for an average person to develop some kind of dependency). Does it relate to different amounts of dopamine binding in the dopamine receptors (D1,D2) in the basal ganglia?

Well heroin is definitely more euphoric than alcohol, so that is probably a big factor.

Part of it also might be not the pharmacological reasons, but the way alcohol is accepted in society.

You can be functionally addicted to alcohol and casually drink beers all the time and no one will think anything of it, but being a casual heroin isn't accepted.
>>
>>7932538
Addictions disappear when you find something better.

Most people have something better than alcohol to begin with so it's non-habit forming, but when you take a stumble in your life and don't have any better way to feel self-content, alcohol easily becomes habit forming. Sometimes life picks back up and the cravings wean away.

There's nothing better than heroin, even having a great life, so anyone who takes heroin is gonna get fucked up
>>
>>7932538
alchohol addiction is a negative addiction. heroine is overtly positive

Hi /sci/ undergrad mech engineering here. How did most of you get good specifically in physics, I can solve a lot if its given simply, but once a problem is given in a different way where I have to derive and find angles with wacky formulas I get lost. Is there something I'm missing besides practise? No memes and eng hate you can fuck off

I can't find an answer for this anywhere, I'm getting desperate for help, so I hope someone is willing.

From my understanding, in an electromagnetic wave, the direction of propagation is perpendicular to the magnetic and electric fields, which are perpendicular to eachother as well.
for example,
E x B = direction of propagation

If given an Electric field equation of a EM wave, like e.g E = E_o x e^(ky-wt)

and nothing else, how do I know whether the direction of the wave is in the x or z direction? as both are perpendicular.

I have to answer a multiple choice where there is a choice for all 3 directions. I'm not given the magnetic field, only that equation above.

Stop trying to make us help you pass your phys/chem midterm. Learn you useless, degenerate, piece of shit.

This is kind of /pol/, however I need logical (logical 4chan lol) to assist.

I have a mega liberal friend who, in the case of this hypothetical refuses to rectify his logical error.

His claim is that all life is equal, regardless of any and all life choices, and that all life is worth saving.

However, he claims in this situation that it is better to split the medicine and "at least try" to save both lives, even if it definitely means they will both die, rather than saving one.

Thus, someone who claims that all life is worth saving, is also claiming that at least trying to save both is worth more than ACTUALLY saving one.

How would /sci/ approach this?

I believe you would go with the one that has a higher chance of success. The drugs in the other man's system will make it hard for them to treat him without first purging his system. Purging takes time, and his life probably depends on a timely transplant.

>trying to save both
