11:00 PM
hence my confusion
 
so we both need more context
perhaps you're supposed to prove that or disprove that?
no i mean what is the context?
 
where did you get that sentence?
 
question 1
 
hahahaha
a and b are not the questions
they are mathematical statements
 
11:01 PM
oh
then the question is the last bit
 
the question asks you to write the negations of those statements as clearly as possible
yeah
 
i thought that applies to question 2
 
no
 
well thats alot easier
 
It's above problem 2
hence part of problem 1
 
11:02 PM
yeah i need clearer instructions than that to not get confused
 
shrugs
honestly that's bad problem formatting
 
<== brain < retarded
 
problem 1 should've said "Consider and negate the following statements."
 
i would of understood that lol
 
@Faust do you mean that in the sense of mental illness or lack of skill?
cause tbh that problem is badly formatted
most of my math class last spring would've complained about that for sure
 
11:04 PM
i Have something called dysgraphia and autism
 
oh
that is not the same as being retarded
not even close
 
Are you an undergrad math major @Typhon?
 
its very hard for me to understand clear instructions
 
@Jasper yeah
 
let alone confusing ones
 
11:05 PM
@Faust Fair enough.
@Faust I wouldn't sell yourself short though. You have to be pretty darn smart to be studying graph theory, lol.
@Jasper also a computer science major
 
@Typhon Very much work needed for a double major.
 
@Jasper it's really not that hard. Not for me anyways.
 
@Typhon evewry heard the term idiot savant?
ever*
 
@Faust nope.
 
@Faust Nope, lol.
 
11:07 PM
it was created to describe people with autism
 
<=== also, if you click the arrow there is an edit button.
@Faust I would see that as a decent description. Naive could also apply.
 
perhaps tell someone tells you to play the colour purple...
 
you can't play the color purple.
unless colour isn't a typo?
@Faust I'm guessing that confuses you and other people?
 
color?
we but a u in it
 
what is colour?
it's spelled color?
 
11:13 PM
only in usa
not in canada or uk
 
Colour is the British spelling.
 
ugh
 
its colour
 
Color is the American spelling.
 
fine
fair enough
 
11:13 PM
Likewise, we have diarrhoea and diarrhea, LOL.
 
anyway eithier moxart or beetovhen
 
ok
 
asked his musicains or w,e to play the color purple
apperntly he could see music in colors
 
Also, tomato is pronounced very differently in the UK than in the US.
 
its dysensia or something
 
11:14 PM
@Faust I've heard of that
that's freaky
so what was the color purple?
 
it was a specfic note he wanted played
 
yeah, I meant what note. XD
 
Purple is the colour I hate the most.
 
but no one could "see" the colour purple so they had no idea what he was talking about
 
don't say "see"
 
11:15 PM
whats the write word?
right*
 
he saw the color purple when certain notes played. It's not that weird. Just bad wiring in the brain.
@Faust i meant no need for quotes
:p
 
ah
 
Maybe it's good wiring? LOL
 
english language is nonsense
 
@Jasper depends.
what if you go to a concert and are literally blinded by sound?
 
11:17 PM
i can glimpse numbers but its hard requires alo of focus not natural
 
English is a very complicated language. When you see the questions on the Eng SE sites, you feel you no longer know English.
 
@Faust like... actual hallucinations?
that's cool.
 
in my mind
 
oh
 
like i can push them together
 
11:17 PM
that's called imagination
 
to genreate other numbers
 
i think
 
without adding them
 
There was once I went off my meds and I could hear the wind blowing in my ear once every hour.
 
or multipling
 
11:18 PM
small numbers or large numbers?
 
sometimes my brain can see a solution i can't interpret
its always correct
 
That's called genius.
 
hahahah
 
even if it takes me an hour to figure out why its correct
 
i know what it is
 
11:18 PM
if i get a diffrent number than i need o do question again because its always right
than it*
 
en.wikipedia.org/wiki/Adder_(electronics) yer brain has one of these in it somewhere
like... in the sense that you must've grown a biological adder
only thing I can figure
that's pretty darn special
 
There are people who can add numbers faster than you can even read them.
 
brian is smart
 
I can't do that.
 
i can just somtimes hijack something meant for something else to do math
 
11:19 PM
@Jasper yes, but they do so consciously.
 
Like they can add 10 3-digit numbers in less than 5 seconds.
 
this sounds unconscious.
 
These people have brains wired differently from ours.
 
it kind of is but i see the result without computing it
brain computes it
but i dont trust it :P
so i do it myself
 
@Jasper hence why I said it's like his brain grew a math circuit. He can just add numbers instantly with no conscious thought.
 
11:21 PM
oddly my medication dulls the effect
 
@Typhon Yeah but these people who are good at arithmetic, well, I don't think they really excel in mathematics itself.
 
Whenever i take dexedrine or adderall it gets weaker
 
@Faust yeah but I mean you don't have to think about the term by term adding. It just does it. If it were my head, I'd probably give it some large numbers to try and see what might happen. I'd be especially curious if it has overflow or underflow errors.
@Jasper excelling in math is a skill that is obtained through practice. Raw brainpower has no help there. So that's no surprise for me. I hate raw arithmetic.
 
ive been with it for a long time (realized when i was a kid) in that time through numerous classes of math physics etc ive never know it to be incorrect
 
intriguing
shrugs
 
11:23 PM
is what it is
 
@Typhon I think other than practice it also requires some talent. I don't agree that genius is 99 per cent perspiration and 1 per cent inspiration. Maybe more like 50 50.
 
is it good with non-numerical things like integrals and stuff or is it just arithmetic?
 
geometric things
its much much better than i am
it came up with a special case of stokes theorem on its on
totally baffled my physics prof
 
@Jasper true, but pure raw computing power is irrelevant. Otherwise computers would be solving proofs with little to no difficulty. Even the most simple integrals allude them at times. Humans still beat computers cause we have the ability to actually think about problems
i think that is what you refer to
 
@Typhon I am very amazed though that Deep Blue beat Gary Kasparov in chess.
 
11:25 PM
ehhh, when it comes to integrals I'm a bit dubious.
I'm not saying that mathematica, for instance, can do every possible integral.
 
Well, Waiting is the world's leading authority on integrals. =D
 
@Semiclassical cough mix the floor function in cough
 
but I'm skeptical that the exceptions would count as 'simple'
hmm
 
@Typhon basically it can do anything i can do just better and faster but i cant control it just like 10-15% of the time it says the answer is "dah dah dah etc" with no proof
 
x^2*floor(x)^2 I believe beats wolfram alpha
and I can do that by hand quite easily using the proper methods
 
11:26 PM
even if im 15 steps away from a solution
 
I have never used Mathematica or Maple or Matlab or Wolfram, LOL.
 
interesting
what if you specifically want step X?
 
However, I did use a pocket calculator, LOL.
 
XD
 
nope final answer only
 
11:27 PM
hmm
sounds like some kind of multi-use dynamic circuitry
 
Interestingly, if I do something like
 
I'm a computer science (programming) major
 
Integrate[Floor[x], x, Assumptions -> 10 > x > 0]
 
so I apologize if I'm acting weird about it
 
@Typhon perhaps some broken multi-use dynamic circuitry :P
 
11:28 PM
then it does give a piecewise linear function from 0 to 10.
 
it's just intriguing as it seems like it implies that your brain is somehow doing something normally unfeasible.
as in, if we recreated whatever that is that your brain is doing... it would beat some math algorithms by a long shot
 
@Typhon perhaps it works the same as everyone else's im simply more aware of it due to some mis-wiring
 
I'd characterize it more as doing something which the program wasn't expecting.
 
@Faust jumping 15 steps ahead is not like everyone else.
 
perhaps it was simply doing the problem with me and simply finished faster because its more efficent?
 
11:30 PM
@Faust true, but it's the fact that it is subconscious that is intriguing
 
i dunno it works oddly if i take enough medication it basically goes away entirely =)
 
that would make sense if it is the result of unique brain chemistry
or configuration
 
my brain doesnt fire neurons correctly
 
the medication would disrupt whatever it is that does that
I'd argue they fire more correctly
but I don't know of any health risks your misfiring might cause
such as organ failure
 
the medication increases the number of firings per second to supposibly help me keep my train of thought
 
11:32 PM
(or organ shutdown to be more precise)
 
i should get back to work
 
@Faust It's probable (but I'm no biologist) that the firings not going into your train of thought are going towards a pretty decent computational engine
k
cya later
 
ttyl =)
 
@Semiclassical I just put x^2*floor(x)^2 into wolfram alpha and it couldn't integrate.
there is a closed form answer I think
difficult to find
but it exists
 
the funny thing is that the function on each [k,k+1] interval is simple
 
11:35 PM
indeed
 
and so it's easy enough to identify the antiderivatives up to additive constants
 
@Semiclassical floor within an antiderivative can sorta be rephrased as a "functional equation" requiring you to find a continuous function satisfying certain qualifications.
 
but there's a different additive constant for each interval, and identifying those is the not-obvious part
 
the trick is to only look at antiderivatives up to additive piecewise constants.
that allows for a superset of discontinuous antiderivatives
 
right.
 
11:37 PM
which are trivial to find
you just substitute floor with a constant and integrate and then substitute back
the functional equation aspect then asks one to find the piecewise constants that when added to the result gives a continuous function
that completes the integration
so an algorithm sorta exists
 
I suspect there's a clever way to do it, but eh
i don't have the energy to think about it
 
@Semiclassical that is the clever way
and extends to diff. eq.
fully, except for the partial derivative case
 
eh, not clever in the way I had in mind.
but i'm not really able to formulate what I have in mind, so it's a moot point
 
@Semiclassical fair enough, but if you have a table of ways to solve functional equations of that type and especially a table dealing with e^(f(x,floor(x))) type things then you basically solve all linear homogenous diff. eq. with piecewise constant coefficients.
i don't know the usefulnes mind you.
 
ehhhh. i think you're overstating it slightly: the intervals here aren't arbitrary
 
11:41 PM
@Semiclassical ?
not sure what you mean
 
well, the following is also piecewise constant: 0 from 0 to 0.5, 1 from 0.5 to 0.75, 2 from 0.75 to 0.875, ...
 
uuuh
no
it's not
im pretty sure measure theory rejects that
ironically I don't know measure theory
 
sure it is. it's not piecewise with respect to [0,1], [1,2], [2,3],...
 
oooh
change the coordinate system
 
something like that.
 
11:44 PM
genius
dude
yer a freaking genius
 
i guess my point is more that you're assuming that it's constant on 0 to 1, and on 1 to 2, etc.
but you could pick different intervals
 
Just use a ruler to measure, that's measure theory, lol.
 
@Jasper referring to the analytical side of such as lebesgue measure and stuff
 
that still counts as piecewise constant. so I think the example you give isn't quite generic enough.
 
@Semiclassical actually piecewise constants are defined as the following in my eyes
let f be a continuous function
g(x) = f(x) + h(floor(x)) where h is a continuous function and g is continuous
actually that's not what I used to use
 
11:46 PM
@Typhon I did my undergrad paper in measure theory. =D
 
it's been so long since I messed with this
i stopped thinking about it cause I finally had enough to say it was likely true
XD
 
well i was mostly trying to rigorize the concept of the intermediary integral i used.
 
Is intermediary a word?
 
which is the inverse of the "implied derivative"
which is basically a multi-valued derivative consisting of the two one sided derivatives
 
11:48 PM
pretty sure it is, though I think it's typically a noun and not an adjective.
 
@Semiclassical that's someone who intermediates
intermediary is an adjective
 
Oh but I think we should use intermediate there.
 
oh maybe
ugh, grammar.
 
Intermediary is someone who carries messages between people.
 
dictionary says both meanings are valid
 
11:49 PM
Oh OK.
 
@Semiclassical changing coordinates was what was going wrong with the 3d renderer i have to help fix up for my senior design. So... that bit of inspiration was quite helpful
 
ah, neat.
 
yay lighting is fixed
 
Sorry I don't trust dictionary dot com, lol.
 
11:49 PM
XD
 
@Jasper but everything you read on the internet is true
 
Unless it sources from respectable dictionaries.
 
@Semiclassical you ever get ur tuition sorted?
 
yep, whew
 
11:50 PM
@Typhon By the way, have we talked before today?
 
@Jasper Merriam-Webster?
 
congrats +)
 
@Jasper no clue
 
@Semiclassical That's one American standard.
 
hey
im curious
what happened to the moderation chat?
 
11:54 PM
They made it private for now, for good reasons.
 
that makes no sense though
the point of the chat was for us to contact them
 
eh, that wasn't the only purpose
it was also for mods to discuss stuff
 
I guess there was too much crap being said in there, too much noise.
 
but it was the primary purpose
I heard rumors that a moderator deleted it out of spite
cause he was getting banned
 
The mod getting banned from what?
 
11:56 PM
idk
 
Nonsense.
 
i heard that some moderator who got in trouble for something or was really rude a lot did that to spite the mods
some amin guy?
(no not admin)
 
Amin is not a mod, lol.
 
oh
 
And that's a whole nother issue.
 
11:57 PM
ooooh
they deleted the mod chat because of what amin did
I've spoke with amin before
been gone a while
what happened?
 
Let's not add more drama now.
But the mod chat thing has nothing to do with Amin.
There are several different issues here I am aware of, which I won't discuss, because I don't want to add drama.
 
alright
fair enough
i wasn't sure if it was something simple
like he spammed or something
 
By the way, you had a fight with another user in the Education Opportunities room @Typhon?
