The new chat thread - now with bitter arguing

i hate nernst. oh, and also donnan.

it's been a while since i did one of the really-uber-exams and fitting about 700 pages of this in my head seems impossible, especially now that i understand a third of it :p

luckily i don't have back pains, migraines are enough. the pills that the doctor gave me to try only worked for the first half of the month, so i'm uncertain about trying for another month, they make me feel weak.
 
@hilj: i hope you find something that works for you, from what i hear migraines can be awful. do discuss your doubts with your doctor.
i have an uber exam in a few weeks too, but i'm not worried about information fitting in my head, i already assume they won't. :D

turns out my back pain was a sore muscle, self-massage rules.
 
Fuck me running I made over $1000 in two days :Spin:

C'mon I'll buy you all beer, Laphroaig, back-pain medicine, donuts, meatball heroes, happy juice, and whatever else you exam-taking overworked-poorbasta'ds may be in the mood for.
 
@siren: massages do rule :) mr hilj's father is able to do some very painful but quite effective neck massages that help my migraines.

i decided that i'll ask for some help on some parts of the exam, i'm starting to see weird math symbols that i could only describe as weird Es with even weirder letters on the top and on the bottom, and i doubt i can explain it this way at the exam.

Are they Greek sigmas? ([SIZE=+2]Σ[/SIZE]) If so it's summation. It's just a shorthand of writing a very long sum of related terms, so by no means should you be discouraged :)

yeah i know the summation symbol :), but this one has little things written over and under, technically the book should explain what "l" "g" and "n" are for, but it doesn't, at least, not yet. so it's not clear for me how i should read and apply it. i'm gonna ask to someone who remembers what was said during classes :p

its weird that the book doesnt even explain the formula...
isnt there anything usefull on wikipedia?


i have an awfull math exam on Feb. 25.... i dont know yet how I will manage to understand all the demonstrations, and when i try to do the exercices, there's always something I cant do.

I will have a quite a few difficult exams this semester. Maths, Eletrotechnics, and materials science (all those symbols to remember, and the very specific vocabulary, when you learn that in a foreign language its not easy to understand everything).
 
Oh hey, instead of memorizing what specific letters mean (because they can change) just keep in mind this: In summations like that one usually increments a specific number by 1 at a time. At the bottom of the Sigma is the information about which is the thing that is incremented (1 at a time) and where it starts (what its first value is). At the top of the Sigma is the information about where to stop (what the last value is). And at the right of the Sigma is the form that each term takes.


[size=-2]8[/size]
[size=+2]Σ[/size] w
[size=-2]w=3[/size]

means: 3+4+5+6+7+8 (which = 33)


[size=-2]31[/size]
[size=+2]Σ[/size] 2/y
[size=-2]y=28[/size]

means: 2/28 + 2/29 + 2/30 + 2/31


[size=-2]m[/size]
[size=+2]Σ[/size] 2n
[size=-2]n=1[/size]

means: 2(1) + 2(2) + 2(3) + ... + 2(m)
 
@D_S: i'm sure the book explains somewhere, but it's not very well done, it uses the same letters for different examples, and it does not state clearly when the meaning is changed and what it means then. so i spend quite some time wondering for example what an ion would do in a summation, because previously the same letter was used to indicate, say, sodium and now it means another kind of thing

@MagSec4: wow thanks! that helps a lot :) my math is very poor and it's hellish to spend a lot of time trying to find comprehensible mathematic notions while i study physiology or other unrelated things.

that reminds me of my very awfull math exercices...

Sorry to talk about old news but:

Aye congrats, mind sharing how you came upon your small fortune?

On the topic of whiskey: you need to try Bushmills 16 y/o. Great stuff, but about $50 a bottle.

Nick
 
Hiljie: Yeah, no problem. I'm glad to be of help.


Nick: Trading stocks. It's good to have good gains when I do have the chance. The problem is that I don't always have the time and care that one needs to do it successfully. I've had some losses as well, and sometimes I miss the chance to take gains. But it's been generally good.
I've never tried Bushmills. Of the more mainstream Whiskeys out there, I personally prefer Chivas Regal, a great quality and nicely-aged Scotch.
 
BTW, how do you pay taxes on those gains? I mean - what's the order, if any (do you report those or get some form or whatever?)

Also

Rocky Balboa was shot on our block 2 years ago (just night before we left for Hollywood). Last night and tonight there's a film crew shooting something in our building - in the apartment above mine, hall, entrance and tonight right outsied my window. So I hear "Action!" and some acting. No, it's not a porn flick.

Haha, speaking of which: I live between sex shop and ganja novelties place (not a joke - both places are quite famous and been around for years). So, this morning I was awaken by a guy from sex-shop - scary 40 year-old punk rocker with a hawk (whatever you call those?), "Punks not dead" t-shirt and severe hangover, who was banging on my door at 8 AM, his question was about a hundred dollars Anal... pardon me - Alan owed him. It appeared Alan was supposed to be in the apartment right above ours... Gee, it's a fucking center of the universe or what?
 
^Sounds like fun. Reminds me of this weird English program to rehabilitate old punk rockers who left school as teenagers and now are pretty much broken, smelly and brain-damaged. Don't know how well that's working.
 
@plintus: i don't know about the US but in europe the trading firm you use pays your taxes for you.
 
plintus: When that time of the year arrives, you'd get a form from whoever handles your trades. That'll tell you what amount is taxable.
It's like the W-2 form from your employer, and the form your bank sends you regarding the interest you earned.
