I am taking Linear Algebra II this coming fall semester and we have been using the textbook Linear Algebra - Fraleigh, Beauregard. Can anyone recommend me some supplementary texts that can further my understanding of linear? I feel as though the current text does not do a great job.
>>9148976
Lay is commonly used. My first course used Anton, which I found readable. Axler's text is a meme, but still probably worth checking out. And then there's Strang.
This right here.
Ill look into this
After I am admitted to grad school for chemistry, when do I start? That summer? The coming fall? Thank you.
And here ladies and gentleman is the proof that a undergrad means shit in this day and age. This retard can't barely conceive the notion that this answer may vary based on his particular program or method of entry and that his best approach would be looking at his particular institution.
>>9148884
I'm guessing this retard hasn't even started their undergrad yet and is just thinking they're automatically going to be a chemistry grad student.
Really depends. How big the program is, how popular your advisor is/desirable to join his group, how large your incoming class is, your selection of possible advisors.
Me personally, I had a small incoming class of 29. My number one choice was THE guy to join but he was able to take 2-3 students. I moved in about a month before the semester start and immediately began attending his group meetings and getting involved. Joined his group the day before the official start of the semester. He was the main reason I chose where to go but my two back up Professors were half bad options.
How do l imagine 4 dimension functions? Seriously l can't. How would you imagine a 4 dimension sphere like this for example? 1 = x^2 + y^2 + z^2 + w^2
You shouldn't be able
>>9148622
>4 dimension sphere
There's your first mistake, let go of what you know of all other dimensions.
>>9148622
think about 3d cross sections
What I've been taught in primary school about math and physics of motion:
>Your position/coordinates are the basic and most relevant information
>Speed is a just neat way of representing the change of position
>Acceleration is just a neat way of representing the change of speed, ie. Change in change of position
Fast forward past my first worthless degree.
What I'm being taught now, as I try to grasp higher physics:
>Acceleration is the most important thing and the only one with real relevance and tangible effect
>Speed is that thing that changes when you accelerate. Barely matters on it's own and can be safely disregarded most of the time
>what the fuck is a position
Life was easier before humans invented science.
>>9148617
lol OP I laughed sry your thread has no replies
>>9148617
Babbys first
Well, if you weren't a retard you would have realized that the easiest variable to change in a physical system between the three is acceleration, it is also the one that is mostly constant/can be described without respect to time most of the time.
Which periodic elements could a human drink in liquid form without dying?
>>9148586
Any in a small enough quantity
>>9148586
Any liquid you drink besides water is poison, but won't necessarily kill you. Stay well under the LD50 and you'll probably survive. Anything emitting alpha particles stay away from though.
>>9148586
Liquid nitrogen and similair inert undercooled gasses you could probably drink a cup of if you drink slow enough.
Of all things I cant wrap my head around how do we see distant galaxies and stars.
Do lenses,like,zoom to that distant place or its just about being sensitive enough to detect that weak light from those distant objects?
>>9148268
Yes

what's with the waves of yesposters recently? not only on /sci/ but other boards as well.
is this what millenials find entertaining?

All acceptable evidence points to East Asians being the most intelligent of humanity.
>outperform all others in measures of intellect
>aren't ashamed of their past like Euros
>>9148143
No arguments here.
>t. white guy with Korean bf
>>9148143
No arguments here.
>t. half white half Chinese guy
Also, sage for not science.
>>9148143
Not really, or you can say that they are intelligent but then you will have to say that Whites are transcendental. Asians can have a civilization by themselves but without white people they are extremely backward and not really that intelligent when you consider that they literally study all day and are just as smart as whites who don't study at all. Whites try to transcend(or should I say tried) while everyone else just has a primitive objective. You simply can't compare.
The Origin of Life
whodunnit? was it magic soup? jesus? aliens?
How long until we figure out all the steps between simple organic chemistry to full mitosis?
>ITT speculate on how2copypaste
I'm still baffled why would nature even do "life". Why would molecules want to replicate themselves? How does that help them reach lower energy levels? (presumably that's the only thing a molecule wants to do)
Molecules can end up in extremely stable states but still maintain some complexity
If a set of molecules happen to replicate, then the replications will probably also replicate. That repetition is the closest thing to things "wanting to replicate"
>all natural systems can be described mathematically
>consciousness is a natural system
>consciousness can be described mathematically
Which, if any, of these statements is false?
Your follow-up question will be "Then why haven't we done so?"
>>9147873
No it won't. The answer to that is obviously a combination of practicality and the lack of a reliable model of reality to house the consciousness.
I'm merely interested in different opinions on the matter from /sci/. There's no right answer until a falsifiable test for it can be determined.

How do we stop this charlatan?
Do people change or is personality permanent? How much can people change? Give some an anecdotal examples to prove your point if you want.
>>9147541
>Give some an anecdotal examples
that's all you can get in psychology, since it's not a science
I would say by the time you're 25 your personality is permanently set in stone. Experiences in the formative years will shape it greatly
>>9147558
25 is a good age. Women look best around that age. Most males have bleed off most of their retardation.
Story Time:
Hey /sci/, so I've experienced a very near death experience on lsd. I'd rather not get into the exact specifics but basically I jumped from a second story balcony, busted through a pool cage, and fell into the shallow end of the pool. For obvious reasons I could've sustained extreme brain damage or death during that set of events but thankfully I didn't. This was the worst experience of my life and I've been getting slight flashbacks of the experience. I would really love to take acid again, but I'm afraid I'll fall into a bad trip of reliving that moment. Do you guys have any advice of how to get over the experience and the fear? Have any of you had any experiences like this on acid and dealt with it?
>>9147368
get a tripsitter
someone you trust to not let you do stupid shit, who can do so with force if necessary
other than that, lock your balcony doors, any windows, any doors etc. etc. etc.
you had a panic attack because for a moment your brain on lsd was finally able to realize exactly how stupid it is.
the panic came from realizing your general lack of ability to cognate beyond the scope of rewarding your ego for anything longer than thirty seconds in the future
i would suggest stopping all forms of degeneracy until you get your shit straight, though if the pool cage is not yours, or the property isn't your families, you should kys. really

ghost and then [untitled]... the emotion apex of the album... but it's better to listen to it in the context of the album
I don't find stimulation or inspiration to be particularly helpful when studying, personally. I listen to various Post Rock bands that I have listened to a thousand times before.
Pleasant, but not distracting.

So what about an "infinite set"? Well, to begin with you should say precisely what the term means.
Okay if you don't, at least someone should. Putting an adjective in front of a noun does not in itself make a mathematical concept.
Cantor declared that an "infinite set" is a set which is not finite. Surely that is unsatisfactory, as Cantor no doubt suspected himself. It's like declaring that an "all-seeing Leprechaun" is a Leprechaun which can see everything. Or an unstoppable mouse is a mouse which cannot be stopped. These grammatical constructions do not create concepts, except perhaps in literary or poetic sense. It is not clear that there are any sets that are not finite, just as it's not clear that there are any Leprechauns which can see everything, or that there are mice which cannot be stopped.
Certainly in science there is no reason to suppose that "infinite sets" exist. Are there and infinite number of quarks or electrons in the universe? If physicists had to hazard a guess, I am confident that the majority would say: No. But even if there were an infinite number of electrons it's unreasonable to suppose that you can get an infinite number of them all together as a single data object.
>>9147282
>Surely that is unsatisfactory
how ? even a brainlet can understand this, it is simply a set that contains more elements then any subset of it containing a natural number of elements .
An infinite set is a set that you can't map a finite set into. It's not particularly ambiguous or ill-defined. Considering the practical applications of the results of Real and Complex Analysis. It does not particularly matter whether or not they "actually exist", i.e. if the universe is actually some plank-intervalled machine that is using mechanics which only "approximate" infinite continuity; infinite sets and Cauchy sequences have already proven their worth.
Is this guide any good?
>>9147225
>transition to advanced mathematics

Clearly written by a CS brainlet.

nah, just another memelist
The ordering is intentionally retarded. Probably as a joke or a bait. Learning it this way would be like saying you have to learn Molecular Chemistry before you learned Newtonian Physics because physical objects are made of molecules.
