fuck off with your autistic shit
Ask for advice, give advice, cry and celebrate that you did or didn't get the place that you want.

How hard does ee get in the final years?

Anyone here doing enviro work? swiching majors after this year.
>>8061757
sort of? i was in environmental science then dropped out for a couple years, moved around the country and now i'm majoring in geomatics. i think it's really interesting in any case. options are pretty open ended so "enviro work" is afterwards is totally an option depending on who you work for, though the opposite is also a possibility (resource extraction industries etc)
I want to kill myself.
But since you die only once, I want my death to be something special. So please give me scientific suggestion for an orioriginal method of suicide. Best suggestion will be executed in public.
>>8061361
Get helium tank
Tie uninflated balloons around neck
Inflate balloons
Die or fly into space
>>8061361
don't do it in public
people already got enough problems, they don't need to have their week ruined by seeing some angsty asshole commit suicide in a flamboyant way
What's a good short combinatorics book that covers all areas of combinatorics at least to a small extent?

If we are truly living in a multiverse and our world is one in an infinite variety of expanding and collapsing universes, is it possible for our body and brain to be reborn in a parallel universe? Not as in us being reborn as a buddha and remembering our previous lives, but a carbon copy of us like a clone. Same DNA, same body, same neurons, no memory of past lives, just a different universe. Could this be a form of reincarnation or am i just being autistic?

>is it possible for our body and brain to be reborn in a parallel universe?
Why don't you go ask Jesus.
>>8061166
Not literally our brain, if there is infinite universes then some of them are bound to be similar to ours... and eventually a version of ourselves will be born. Not literally us but might as well be us, if we are nothing but neurons and chemical reactions an exact clone is technically us. No time travel or wormholes just the power infinity..

Good news Anon, "you" are reincarnated as a wave on the pacific ocean every day.
How do I obtain sodium metal?
I live in a nanny-state where I can't buy this from suppliers or import it from China. I've also looked at how to synthesis it from sodium chloride/carbonate but thats 2scary 4 me
I only want about 30 grams
What unregulated items contain sodium metal?
>>8061121
>What unregulated items contain sodium metal?
Bottles of sodium metal.
>But they're regulated!
Well how the fuck am I supposed to know what is and is not regulated where you live?

use some common sense???????

Do a reaction you pussy
I've heard it is around 200 people competing for one tenured post so your chances of getting it is about as slim as you becoming the next Taylor Swift. Why would anyone want to do research then? Being in a publish-or-perish environment ain't fun. You will be flipping burgers if you have nothing published.
>>8061019
I want to research Taytay's body, alright.
>>8061019
>200 : 1
that's substantially better than my becoming the next Swift

Well I mean doing a PhD
As humans, and perhaps as mammals more generally, we are used to the following theme:
Women looking beautiful, and men doing what they can to impress them to win access to their vagina.
Studies of sexual partners seems to back this up: Women are more choosey, whilst men sleep will sleep with right munters. Chat-up lines are learnt by the men; PUAs exist to teach men how to pick up women, etc.
In the mammal world, the typical rule is that the men are stronger and more physically capable than the women. The competition for which male is most physically superior is one...

>So.... can you think of any species in which the burden of attracting a mate rests more on the female?
This would potentially happen to a species where the burden of carrying young falls on the male.

There are always exceptions.
Your mom, for instance.

If your theory holds water, sea horses would be a good case study.
Let's say I need to prove that the expression of a function f(x) can be re-written in some other way than its original expression.
To do that, can I just assume and state that both expressions of the function are equal, and then see how it goes from there? So that if I will arrive at an equality with same expressions on each hand, the proof will be completed. (If the opposite is true, though, it would prove that the function can't be re-written as that expression)
Is there a faster and more acceptable way to do proofs like that?
>>8060942
Proof that the thing that is changed is the same can sometimes be faster. Can u give an example?
>>8060949
This is a very basic example that I came up with:
Prove that the square root of x^3 can be rewritten as x^(3/2).
What I do is write sqrt(x^3) = x^(3/2), and then work from there.
>>8060958
Why would you need to proof this? These are two times literally the same function. Wtf anon?
Thoughts on Cognitive Science as a major?
I mean, I know interdisciplinary studies can kinda suck- but it seems decent as a way to officially study technoshamanism.

I mean, I've done a lot of drugs, and well- it seems like the shit I've already been interested in.
It's either that or something like logic.
>>8060660
I'm interested in cog sci as well. I'd love to create an IQ test for highly gifted people such as myself. Unfortunately the conventional IQ tests stop being accurate at 160 but mine is definitely higher.
I don't know how it works in the states, but you can do dual majors or even dual degrees over here -- if you're interested in that, spend the arts half your degree doing psych/neuro/philosophy and the science half doing chemistry/neuroanatomy/mathematics
without the science no one will take you seriously, but without the arts you won't get laid, or have a "theoretical framework" to justify all the drugs you're doing
Logic is near
Am I retarded or is everyone else retarded?
How is this any different than how a voltimeter will slightly change the current of a circuit?
>>8060621
As in, the tool you're using to observe the phenomenon will slightly alter the phenomenon?
>>8060621
I suppose it would be different in the sense that the observing mechanism is not changing the frequency or measureable input or output, but the actual perceived state of matter or energy in question.
>>8060621
But measurement doesn't merely slightly disturb a quantum system, it completely changes it.
Hi /sci/
I'm about to wrap up a math undergrad. I focused my curriculum on probability & statistics since I found this to be the most interesting. This means that I've omitted a lot of abstract algebra that I could have taken. Pic related is the textbook used for the algebra sequence at my school. I think the Dummit & Foote book is split into a 3 course sequence on abstract algebra. Is this book any good for self study? Is this too babby tier? I'm fairly strong (for an undergrad) in analysis & functional analysis but I only have experience in...

I'd say bad overall for self study. It's a classic though, and there are lots of solutions online. Be ready to discuss with other people if you want to work through the book and complete all exercises.

i thought it was shit, fraleigh is much better
First of all what do you plan on using algebra for?
Second of all, at least for self-study, Aluffi > D&F

Ridiculously dangerous chemical compound/pathogen/anything thread.
"It is, of course, extremely toxic, but that's the least of the problem. It is hypergolic with every known fuel, and so rapidly hypergolic that no ignition delay has ever been measured. It is also hypergolic with such things as cloth, wood, and test engineers, not to mention asbestos, sand, and water — with which it reacts explosively. It can be kept in some of the ordinary structural metals — steel, copper, aluminum, etc. — because of the formation of a thin film of insoluble metal fluoride...

say you have two atoms
they're traveling towards eachother at the same speed
hat would happen when they collide?
depends on what the atoms are

also depends on how fast
Why we acknowledge other people farts as smelly and nasty yet most people find their own farts bearable or even smelling good?
If this works because we have an hypothetical "unique scent mark" or something, then why other personal body odours such as armpits, foot or halitosis are immediatly identified as nasty even from the owner of the smell?
Makes no sense at all
probably something to do with gut bacteria or olfactory conditioning so we know when a gas is from our own ass and thus not horribly dangerous
>>8060377
>yet most people find their own farts bearable or even smelling good?
my farts must really be toxic then
>>8060377
You think your farts smell better than your bad breath or armpits?
What the fuck is wrong with you? People actually enjoy the smell of their own farts?
