What do you guys think?

it's as dumb as you are
>>8073196
B-but which part?
is the blue mist the singularity?
if I major in electrical engineering can I make and design stuff like bulbs, electric chargers, cheap toys for kids, meme shit like free energy and meme shit like tesla shit?
What else can I do with an electrical engineering?
I saw some robotic shit on youtube.
Also, can I do shit like making a lamp that uses biological shit like fireflies to charge with sun light and then on the darkness it shines?
It would be possible with an electrical engineering?
Also can I do wifi shit and work with arduinos?
You need to do ecological engineering for that
>>8073105
can't I simply take some classes or ask some bio and chemical dude for help?
I really want to study shit like batteries, wireless transmission of energy and information, shit like ilumination systems (lights and bulbs), design some cheap electronic toys for kids, some electronic shit for holydays, chrismass cards, arduino shit.
>>8073100
Yeah, you can do all kinds of shit with an EE degree. For more obscure/specific shit, you might need to do a doctorates or some shit.
Or some companies would be okay and be like shit, he could probably do this shit with just a BS or some shit.
So you can do pretty much any electrical/electronic shit with a shit E shit E shit degree. shit.
Can entropy be reversed, /sci/?
>>8073084
Of course.
entropy can never happen because of gravity
Yes
Its called life
Another question: should the criteria for a thing being life be changed to simply "something that actively resists entropy"? That whole 6 characteristics of life thing has too many exceptions for my autistic brain desu
Who /sliderule/ here?
>>8072999
no thanks i have an iphone
>>8072999
I have a pretty rare Gilson Binary 8.5"
>>8072999
I have one, have had it for about a decade, but I don't know how to use it as of yet. It's pretty similar to that one, except the end-bits are plastic as well.
I also got myself a nice compass kit recently. It passed the >draw a circle test. The trick is to keep the center pinned on a static spot, however. I may use it to go through the Elements the old-fashioned way.
I've been on a primitive kick lately, and I have the above two, and recently I've been looking for an abacus....

phenylalanine is it safe?
yes, so long as you don't have phenylketonuria
That's quite rare though, isn't it an allergy? has there been a study on the long-term effects. I drink zero sugar drinks all the time. Statistical correlations?
>>8072945
structure in pic isn't phenylalanine, it's L-DOPA
What is the voltage at point A? How would you calculate it?
88 Volts
>>8072817
I know for a fact the peak voltage is around 21.9V
What I'm really looking for is how to get there
>>8072815
24V - 2 diode drops so 23~22.6V
So now that it's settled that [s4s] is the smartest board, seeing that that is where eccentric geniuses flock to when they're on their creative downtime, what's next?
/lit/ or /sci/?
probably something like

and 6+ years ago

what's the difference?
>>8072738
probably specific majors at particular colleges that wouldn't generally be classified under what's colloquially thought of as humanities
Are successful/famous mathematicians more talented than their colleagues, or they just simply got lucky? Were these guys seen before their achievements who will further mathematics? Are there any counter examples? Guys with great expectation living up to their potential regarding their impact?
john von neumann would be a good example of a prodigy living up to expectations
although he is probably the smartest human being to ever live, so i don't know if its fair to count him
>>8072715

What's the difference between boolean algebra and propositional logic? Are they isomorphic to each other?
I fail to see the difference between them.
boolean algebra, propositional logic, and predicate logic are all pretty similar
the different names are used to refer to distinct subtle differences between them between each field (e.g. you wont find sets in propositional, but will in predicate)
tl:dr their the same for all intents and purposes and even if you mix them up in your PhD thesis, no one will care and even if they do you are still technically correct
Its all jargon from a leftover era
>>8072305
who cares? the real question is why anyone would study this nonsense
>>8072337

Today I opened this book in the library and got scared.
probably not much, just watch a few documentaries on physics.
anything by stephen hawking, neil degrasse tyson, coral sagan, brian greene, michio kaku, brian cox, or morgan freeman would be fine
ofc the tryhards here will tell you you need some shit 4 year physics degree but they are just trying to justify their own shit life choices.
morgan freeman explains the double slit pretty well
his thoughts on how it might relate to god are also interesting
>>8072205
you still think of god as a person rather than a concept? huehuee
So, how many classes do all engineering classes share in common?
So, following that logic, how many engineering majors can I get (the degree paper) in 10 years of study?
Also, what engineering major is best for making electronics, plastic crap, electric bulbs and so on.
>>8072145
A lot more than you think
>2 years of history, english, and lit classes
>gen ed bio, chem, and phys
>math through at least DiffEqs
Really just the last half of your junior year and senior year, or 36 or so credit hours are your engineering specialty.
>>8072159
This is true. I know a guy who switched from Chem E to Biomedical Systems E at the end of his junior year and is still graduating on time w/o too much effort.
Google is your friend mate, learn to use it.
Suppose f is a polynomial with complex coefficients. Is there a way to test if there are polynomials g and h with degree(h)>1 such that
f(z)=g(h(z)) identically? Is there a way to characterize such f and find the "factors" h and g?
Clearly the degree of f can't be prime. Also, for any complex c, h must map the solutions of "f(z)=c" to the solutions of "g(z)=c" so, for
example, h would need to map the roots of f to the roots of g, respecting multiplicities.
Any other thoughts?
My thoughts are that you can pass to an algebraic equation via
https://en.wikipedia.org/wiki/Fa%C3%A0_di_Bruno's_formula#Formal_power_series_version
and going from small to high exponents (the higher use the smaller ones too),
maybe the solutions can be parameterized by h's coeffieints.
>>8071970
Yes, I you could (once you pick degrees for g and h) multiply out g(h(z)) and equate coefficients. This looks like it would be a mess though. I was wondering if there were a necessary condition based on examining the roots of f. For example, must every root of f have the same multiplicity which is >1 ? If b is a root of f with multiplicity m, then c=h(b) must be a root of g of multiplicity k that divides m, and b must be a root of h(z)-c of multiplicty m/k.. or some such. Seems like there should be a way to make this sharp.
>>8071943
it feels weird.
I feel like f and g can't contain as much information as f.
In fact I'm pretty sure that's key to the problem.
say f, g and h are of degree n, p and q with n=pq
f has n+1 independent coefficients.
g has only p+1, h has only q+1
so I would say a strong condition for f=g(h) would be that (p+1)+(q+1)>=n+1 (basically you need to have more degrees of freedom to be able to fit the resulting polynomial).
this results in p+q+1>=n, or p+q>n.

>there are people on this board who unironically like abstract algebra
>>8071873
As someone in an applied field I feel mislead in that I thought learning the field (and other "advanced" pure math fields) would make me better at mathematics in general, I invested a lot of time working for Pinter and not only were there no useful applications that aren't both simplistic and more easily solvable with unabstracted math in the sense that you can learn it on-the-fly in applied texts which is both easier and more useful. Worse still it doesn't even help you understand advanced applied...

I don't really like it by itself. But I do like Algebraic Geometry, and you kinda need to know algebra to do algebraic geometry.

Nice meme.

Doesn't what? Have free will.

>i mean it's all just atoms, right?
>>8071891
Who are you quoting?
Isn't geometry the basis of every science and perhaps even of everything?
I have just noticed that every single problem I've worked on in every subject was essentially a question of geometry. How are objects positioned in relation to each other and how does this relation change over time, the latter being the question of processes. It always comes down to this.
One could also argue that intelligence itself is the measure of a person's capability to see and work with these relations. If that fundamental truth is discovered, maybe one can increase one's intelligence?
